Derm Terms

A who’s who and what’s what of skincare terminology.


NIA-114™ is StriVectin's patented, optimized form of Niacin / Vitamin B3 clinically-proven to strengthen the skin barrier

Skin Barrier

The skin barrier provides an important function by protecting skin against external / environmental aggressors and helps minimize water loss.


Epigenetics is the study of how multiple factors like diet, exercise, lifestyle and behavior can affect how we age.


Known as skincare’s gold standard ingredient, Retinol helps improve cell turnover while targeting all key visible signs of aging. Retinol can also help enhance visible skin firmness and elasticity and diminish the look of lines and wrinkles. See the Advanced Retinol collection.

Hyaluronic Acid

Hyaluronic Acid is a powerful hydrating molecule that can hold up to 1,000x its weight in water. Found naturally in skin, Hyaluronic Acid diminishes with age and over time which leads to dehydration and the appearance of lines and wrinkles.

Glycolic Acid

Glycolic Acid is the most effective of the alpha-hydroxy acids (AHA), Glycolic Acid exfoliates dead skin cells to reveal smooth, renewed skin.

Oleic Acid

Oleic Acid is an Omega-9 fatty acid that replenishes skin’s lipid layer – an essential component of the skin's barrier.

Niacin/Vitamin B3

Niacin/Vitamin B3, also known as nicotinic acid and niacinamide is one of the most effective ingredients for aging skin. Niacin targets multiple concerns of aging skin, strengthen the skin barrier, visibly reduce lines and wrinkles, improve the appearance of pores, uneven skin tone and dullness.


Skin has three layers. The outermost layer of skin is called the epidermis.


Peptides, an important ingredient in anti-aging skincare, are amino acid proteins. If you're looking to address visible signs of aging, like thinner skin and the appearance of lines and wrinkles, look for products containing peptides and other potent ingredients, like the Advanced Retinol Intensive Night Moisturizer and Multi-Action Active Infusion Youth Serum.


When it comes to hydration and water retention, ceramides are critical. Found naturally in skin, these lipid molecules can help replenish and restore skin, improve texture and leave skin more supple.


Collagen is a protein found naturally in our skin. In fact, collagen makes up about 70% of our skin and is the key to plumpness and elasticity. Collagen is also found in topical and injectable skincare products that claim to restore collagen within skin.

Youth Collagen/Collagen III

All collagen is not created equal. There are 28 types of collagen in our bodies, most of which deal with tendons, cartilage and ligaments. Only two types - Collagen I and Collagen III - impact our skin’s strength, elasticity and firmness. And only Collagen III is the essential contributor to our skin’s bounce and spring, which is why it is known as ‘Youth Collagen’.


Elastin is a protein found naturally in our bodies that possesses elastic properties. It allows skin to “snap back” after being stretched or contracted. Along with collagen, elastin is key to youthful looking skin.

Digital Aging

Digital Aging is the appearance of lines, wrinkles and sagging skin accelerated by technology.

Screen fatigue

Screen fatigue is caused by prolonged use and squinting at digital screens, which can result in weakened skin , dark circles and fine lines around the eyes.

Tech Neck

The average person looks down at their phone 221 times/day. This repeated motion can lead to horizontal neck lines and sagging skin as the head bends forward,  also known as tech neck.


Antioxidants help protect skin from damaging free radicals, which can damage skin and accelerate signs of aging.

Free radicals

Free radicals are often the result of environmental factors like (pollution) as well as lifestyle and behavior (dietary choices, smoking, alcogol consumption). These stressors can damage skin and accelerate signs of aging.

UVA and UVB rays

UVA and UVB are two different types of rays produced by the sun. UVA rays penetrate skin more deeply than UVB rays and are known as primary drivers of photo aging / skin aging. Both UVA and UVB rays are culprits behind premature skin aging.
