Skincare Fundamentals & Skin Health
Why is it important to use SPF every day?
SPF, also called sunscreen or sunblock, is one of the most important steps in any skincare routine. It helps protect the skin from harmful ultraviolet (UV) rays that can cause sunburn, premature aging, hyperpigmentation, and skin cancer. Even on cloudy days or while indoors near windows, UV rays can still affect your skin. Daily SPF use helps preserve the results of your skincare treatments and protects your skin’s long-term health.
What are free radicals?
Free radicals are unstable molecules that can damage healthy skin cells and accelerate signs of aging. They are created by everyday environmental factors such as sunlight, pollution, and smoke. Over time, free radical damage can contribute to wrinkles, loss of firmness, and uneven skin tone. Antioxidants like Vitamin C help defend the skin against this damage and support a healthier, more youthful appearance.
Why is hydration important for skin health?
Proper hydration helps maintain the skin’s protective barrier and supports overall skin function. When skin becomes dehydrated, it may feel tight, appear dull, and become more susceptible to irritation. Hydrating ingredients attract and retain moisture, helping the skin look plumper, smoother, and healthier. Well-hydrated skin is also better able to tolerate active ingredients and environmental stressors.
Mineral vs. chemical sunscreen
Both mineral and chemical sunscreens protect the skin from harmful UV rays, but they work differently. Mineral sunscreens use ingredients such as zinc oxide and titanium dioxide to form a protective barrier on the skin’s surface. Chemical sunscreens absorb UV radiation and convert it into heat before it can damage the skin. Both can be highly effective when applied correctly, and the best sunscreen is the one you will use consistently every day.
What is the difference between dry and dehydrated skin?
Dry skin is a skin type that naturally produces less oil, while dehydrated skin is a condition caused by a lack of water within the skin. Dry skin often feels rough and may be prone to flaking, whereas dehydrated skin can appear dull, tight, or more prone to fine lines. Even oily skin can become dehydrated. Understanding the difference can help you choose products that properly address your skin’s needs.
What is the skin barrier and why does it matter?
The skin barrier plays a critical role in protecting against environmental aggressors while keeping moisture locked in. When functioning properly, it helps maintain smooth, hydrated, and comfortable skin. A weakened barrier can lead to dryness, irritation, sensitivity, and breakouts. Supporting the barrier with gentle cleansers and nourishing ingredients is essential for overall skin health.
What are the different skin types?
Most people’s skin type falls into one of four main categories: normal, dry, oily, or combination. Your skin type is largely determined by genetics, but environmental factors and age can influence how your skin behaves. Understanding your skin type can help you select products that effectively address your unique concerns. A customized routine often delivers better results than a one-size-fits-all approach.
Why does skin become more sensitive?
Skin sensitivity can develop for many reasons, including environmental exposure, overuse of active ingredients, aging, or a compromised skin barrier. Sensitive skin may react with redness, itching, burning, or discomfort. Identifying triggers and using products designed to soothe and strengthen the skin can help reduce irritation. A simple, consistent routine is often the best approach.
Aging, Prevention & Skin Renewal
How does retinol help the skin?
Retinol is a vitamin A derivative that encourages skin cell turnover and supports collagen production. It is widely recognized for its ability to improve the appearance of fine lines, wrinkles, uneven texture, and acne-prone skin. As new skin cells replace older ones, the complexion can appear smoother and more radiant. Because retinol is highly active, it is often introduced gradually to allow the skin time to adjust.
How does collagen change with age?
Collagen is the protein responsible for keeping skin firm, smooth, and youthful-looking. Beginning in our mid-twenties, collagen production gradually decreases each year. Environmental factors such as sun exposure, pollution, and smoking can accelerate this process. As collagen levels decline, skin may develop fine lines, wrinkles, and reduced elasticity. Proper skincare can help support collagen production and protect existing collagen from damage.
What causes fine lines and wrinkles?
Fine lines and wrinkles develop as collagen and elastin production naturally decline with age. Repeated facial expressions, sun exposure, and environmental stressors can accelerate this process. As skin loses firmness and elasticity, lines become more noticeable. Consistent use of sunscreen and targeted skincare ingredients can help minimize their appearance and support healthier-looking skin.
Why is prevention better than correction?
Many signs of aging and skin damage develop gradually over time. Preventive skincare focuses on protecting the skin before concerns become more noticeable. Daily sunscreen, antioxidants, and a consistent skincare routine can help preserve skin health and delay visible signs of aging. Taking proactive steps today can help maintain healthier, more youthful-looking skin in the future.
What happens during skin cell turnover?
Skin cell turnover is the natural process by which old skin cells are shed and replaced with new ones. In younger skin, this cycle occurs relatively quickly, helping maintain a fresh and healthy appearance. As we age, the process slows down, which can contribute to dullness, rough texture, and uneven tone. Many skincare ingredients are designed to support healthy cell turnover and promote brighter-looking skin.
Why is consistency important in skincare?
Healthy skin is built through consistent daily care rather than occasional treatments. Most skincare ingredients require regular use over several weeks to deliver visible results. Sticking to a routine allows active ingredients to work effectively while supporting the skin’s natural renewal process. Patience and consistency are often the keys to long-term success.
How do growth factors support skin renewal?
Growth factors are naturally occurring proteins that help regulate cell growth and repair processes within the skin. In skincare, they are used to support skin rejuvenation and improve the appearance of aging skin. Growth factors may help enhance firmness, smoothness, and overall skin quality by encouraging healthy cellular activity. They are often incorporated into advanced anti-aging and post-procedure skincare routines.
How do growth factors support younger-looking skin?
Growth factors play an important role in helping the skin maintain its natural renewal processes. As we age, the production of these proteins gradually declines, contributing to visible signs of aging. Skincare products containing growth factors help support skin rejuvenation by encouraging healthy cellular activity and repair. This can result in skin that appears smoother, firmer, and more refreshed over time.
Why do antioxidants matter?
Antioxidants help protect the skin from free radical damage caused by environmental stressors such as UV rays and pollution. Free radicals can accelerate signs of aging, including wrinkles, loss of firmness, and uneven skin tone. Ingredients such as Vitamin C, Vitamin E, and ferulic acid help neutralize these unstable molecules before they can damage skin cells. Incorporating antioxidants into your routine can support healthier, more resilient skin.
How does blue light affect skin?
Blue light is emitted by digital screens, smartphones, and other electronic devices, as well as the sun. Emerging research suggests prolonged exposure may contribute to oxidative stress and visible signs of aging in some individuals. While more research is ongoing, many skincare professionals recommend antioxidants to help protect against environmental stressors, including blue light exposure. Daily sunscreen remains one of the most important protective measures.
How does pollution affect the skin?
Daily exposure to pollution can contribute to oxidative stress, which may accelerate visible signs of aging. Pollutants can settle on the skin’s surface and interact with free radicals, potentially leading to dullness, uneven tone, and loss of elasticity. Proper cleansing and antioxidant protection can help defend against environmental damage. Healthy skin is better equipped to withstand these daily stressors.
Skin Concerns & Conditions
What causes hyperpigmentation?
Hyperpigmentation occurs when the skin produces excess melanin, resulting in dark spots or uneven skin tone. Common causes include sun exposure, acne breakouts, hormonal changes, and skin irritation. Consistent sun protection is essential when treating pigmentation concerns, as UV exposure can worsen discoloration. Ingredients such as Vitamin C, retinol, arbutin, hydroquinone, and other brightening agents can help improve the appearance of dark spots over time.
What causes acne?
Acne develops when pores become clogged with excess oil, dead skin cells, and bacteria. Hormonal fluctuations, genetics, stress, and certain skincare products can all contribute to breakouts. Acne can appear as blackheads, whiteheads, pimples, or deeper cystic lesions. Consistent use of targeted ingredients and a proper skincare routine can help manage acne and reduce future breakouts.
What is skin texture?
Skin texture refers to the surface quality of the skin and how smooth or uneven it appears. Factors such as aging, acne, sun damage, and dehydration can contribute to roughness or visible irregularities. Ingredients that promote cell turnover and hydration can help improve texture over time. Smoother skin often reflects light more evenly, creating a healthier-looking complexion.
What causes dark circles under the eyes?
Dark circles can develop for several reasons, including genetics, aging, fatigue, dehydration, and thinning skin around the eye area. As skin becomes thinner, underlying blood vessels may become more visible, creating a darker appearance. Lifestyle factors such as lack of sleep and sun exposure can also contribute. Proper hydration, sun protection, and targeted eye care products, like Vivier GrenzCine Eye, may help improve their appearance over time.
Why is exfoliation important?
Exfoliation helps remove dead skin cells that can accumulate on the skin’s surface and contribute to dullness or congestion. By encouraging healthy cell turnover, exfoliation can improve texture, brightness, and the appearance of pores. Both physical and chemical exfoliants can be effective when used appropriately. Over-exfoliation should be avoided, as it may compromise the skin barrier and cause irritation.
What are alpha hydroxy acids (AHAs)?
Alpha Hydroxy Acids, commonly known as AHAs, are a group of exfoliating acids that help remove dead skin cells from the skin’s surface. Popular AHAs include glycolic acid and lactic acid. By promoting healthy cell turnover, AHAs can improve skin texture, brightness, and the appearance of fine lines. Regular use may reveal smoother, more radiant-looking skin.
What’s the difference between AHAs and BHAs?
AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids) are exfoliating acids that help remove dead skin cells, improve texture, and promote a smoother, clearer complexion, but they work in slightly different ways.
AHAs, such as glycolic acid and lactic acid, primarily exfoliate the skin’s surface. They can help improve dullness, uneven tone and texture, fine lines, and signs of sun damage.
BHAs, most commonly salicylic acid, are oil-soluble and can penetrate into pores. This makes them particularly helpful for oily or acne-prone skin, clogged pores, blackheads, and blemishes.
The best choice depends on your skin type and concerns, and some skincare routines may benefit from using both.
What is salicylic acid?
Salicylic acid is a beta hydroxy acid (BHA) commonly used to treat oily and acne-prone skin. Because it is oil-soluble, it can penetrate into pores to help dissolve excess oil and debris. This makes it particularly effective for blackheads, congestion, and breakouts. Regular use can promote a clearer, smoother complexion.
Why is salicylic acid effective for acne-prone skin?
Salicylic acid is one of the most widely used ingredients for managing acne and congestion. Because it is oil-soluble, it can travel deep into pores to help dissolve excess oil and remove buildup that may lead to breakouts. This makes it particularly effective for blackheads, whiteheads, and oily skin. Products such as Vivier Medicated Wash utilize salicylic acid to help maintain clearer-looking skin while supporting a healthy cleansing routine.
Professional Skincare & In-Clinic Treatments
Why doees professional skincare complement in-clinic treatments?
Professional skincare and in-clinic treatments can work together as part of a comprehensive approach to skin health. Treatments such as laser procedures, chemical peels, and microneedling can target specific concerns, while a consistent at-home skincare routine helps support the skin between treatments and maintain results over time. The right products can also help address concerns such as pigmentation, dryness, acne, uneven texture, and signs of aging.
Should I change my skincare routine before an in-clinic treatment?
Possibly. Depending on the treatment, you may be advised to temporarily stop certain active ingredients, such as retinoids, AHAs, BHAs, exfoliating products, or other potentially irritating ingredients. This can help minimize sensitivity and prepare the skin for treatment. Always follow the specific pre-treatment instructions provided by your clinic or treatment provider, as recommendations can vary by procedure and skin type.
What skincare should I use after a laser treatment, chemical peel, or microneedling?
Immediately following many professional skin treatments, a simple and gentle routine is usually best. Your provider may recommend a mild cleanser, hydrating or soothing products, moisturizer, and broad-spectrum sunscreen while your skin recovers.
Products specifically formulated for post-procedure care, such as Hale Derma, can also be used to help soothe, hydrate, and support the skin following certain aesthetic treatments. Always follow your provider’s post-treatment instructions, as the products you can use and when you can use them will depend on the procedure.
When can I restart retinol, AHAs, BHAs, and other active ingredients after a treatment?
There isn’t one timeline that applies to every treatment. Retinoids, exfoliating acids such as AHAs and BHAs, vitamin C, and other active ingredients may need to be temporarily paused while the skin heals. When you can safely restart them depends on the treatment you received, the strength of the products you use, and how your skin is recovering. Follow your provider’s instructions before reintroducing active ingredients into your routine.
Why is sunscreen so important after professional skin treatments?
Daily sun protection is always important, but it can be especially important after treatments such as laser resurfacing, IPL or BBL®, chemical peels, and microneedling. Skin may be temporarily more sensitive to UV exposure following treatment, and unprotected sun exposure can contribute to irritation, pigmentation, and signs of premature aging. Using a broad-spectrum sunscreen as directed helps protect your skin while it recovers and supports your long-term results.
Can professional skincare help maintain my treatment results?
Yes. While professional treatments can create changes that skincare alone may not be able to achieve, your daily routine plays an important role in maintaining overall skin health between appointments. Products selected for your individual concerns can help support hydration, even tone, smoother texture, clearer-looking skin, and protection from environmental damage, helping you get more from your overall skincare and treatment plan.

Ingredients & How They Work
What skincare ingredients are best for anti-aging?
Some of the most widely used ingredients for addressing signs of aging include retinoids, vitamin C, peptides, and alpha hydroxy acids (AHAs). Retinoids help support skin cell turnover and collagen production, while vitamin C provides antioxidant protection and can help brighten uneven skin tone. Peptides can help support firmer, smoother-looking skin, while AHAs exfoliate the skin’s surface to improve texture and radiance. Daily sunscreen is also essential for helping prevent premature skin aging caused by UV exposure.
What does vitamin C do for your skin?
Vitamin C is an antioxidant that helps protect the skin from damage caused by environmental stressors such as UV exposure and pollution. It can also help brighten the complexion, improve the appearance of uneven skin tone and pigmentation, and support collagen production. Vitamin C is commonly used in the morning underneath moisturizer and sunscreen.
What does retinol do for your skin?
Retinol is a form of vitamin A that helps increase skin cell turnover and support collagen production. With consistent use, it can help improve the appearance of fine lines, uneven texture, pigmentation, and blemishes. Retinol can cause dryness or irritation when first introduced, so it is generally best to start gradually and increase use as your skin adjusts.
What’s the difference between AHAs and BHAs?
AHAs (alpha hydroxy acids), such as glycolic and lactic acid, primarily exfoliate the skin’s surface and can help improve dullness, uneven tone and texture, fine lines, and signs of sun damage.
BHAs (beta hydroxy acids), most commonly salicylic acid, are oil-soluble and can penetrate into pores, making them particularly helpful for oily or acne-prone skin, clogged pores, blackheads, and blemishes.
Some skincare routines may benefit from one or both depending on your skin type and concerns.
What does hyaluronic acid do for your skin?
Hyaluronic acid is a humectant that attracts and retains water, helping keep the skin hydrated and plump. It can help reduce the appearance of dehydration and support a smoother, more supple skin barrier. Despite having “acid” in its name, hyaluronic acid is not an exfoliating acid and is generally suitable for a wide range of skin types.
What do peptides do in skincare?
Peptides are short chains of amino acids, which are building blocks of proteins such as collagen and elastin. In skincare, different types of peptides are used to help support the skin’s natural functions and improve the appearance of firmness, texture, and fine lines. They are often included in anti-aging and restorative skincare formulas.
What does niacinamide do for your skin?
Niacinamide, a form of vitamin B3, is a versatile skincare ingredient that can help strengthen the skin barrier, improve hydration, reduce the appearance of redness, and balance excess oil. It may also help improve uneven skin tone and the appearance of enlarged pores. Because it is generally well tolerated, niacinamide can be a useful ingredient for many skin types.
Can you use multiple active skincare ingredients together?
Yes, but more is not always better. Ingredients such as retinol, vitamin C, AHAs, BHAs, and other concentrated actives can often be incorporated into the same overall routine, but using too many at once may increase dryness, irritation, or sensitivity. How products are combined depends on their formulations, concentrations, your skin type, and your individual concerns. When introducing active ingredients, start gradually and follow the directions for each product.
