It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated! Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin. This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products. Just know very high concentrations (>40%) can feel tacky in low humidity. Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine. Phenol is an antimicrobial preservative used to extend a product's shelf life by inhibiting the growth of bacteria and mold. It's most commonly found in lip care, cleansers, and treatments at concentrations of 1–2%, and can also function as a denaturant, deodorant, or fragrance ingredient. Unlike most cosmetic preservatives, phenol can damage skin at the concentrations typically used in products. Research has identified roughly 1.5% as the threshold at which phenol begins to cause skin damage - sitting within the range it's normally formulated at. It works by denaturing proteins, which is what gives it both its antimicrobial activity and its potential to cause chemical burns, redness, peeling, or stinging. Phenol also has a mild local anesthetic effect, so irritation may not be felt right away even when damage is occurring. The lips and other thin-skinned areas are especially susceptible. The use of phenol in cosmetics is prohibited in the European Union and Canada. In the United States, it remains permitted primarily in OTC drug products such as oral analgesics and medicated lip balms. Niacinamide is a multitasking form of vitamin B3 that strengthens the skin barrier, reduces pores and dark spots, regulates oil, and improves signs of aging. And the best part? It's gentle and well-tolerated by most skin types, including sensitive and reactive skin. You might have heard of "niacin flush", or the reddening of skin that causes itchiness. Niacinamide has not been found to cause this. In very rare cases, some individuals may not be able to tolerate niacinamide at all or experience an allergic reaction to it. I No written reviews yet.
