Glycerin's Benefits and Drawbacks as an Ingredient for Skincare Cosmetics

Glycerin's hydrating characteristics have made it a staple in the beauty industry. Being a humectant, it helps keep skin moisturized and healthy by drawing in and holding onto moisture. However, much like any other skincare component, glycerin has both benefits and drawbacks when used in cosmetics.

Skin irritation is a possible drawback of using glycerin. Some people may experience redness, itching, and swelling if they are sensitive to or allergic to glycerin. You should always do a patch test on your product before fully committing to a new glycerin-based skincare routine.

Glycerin's dependence on relative humidity is another thing to think about. Glycerin hydrates the skin by attracting moisture from the air and locking it in. In low-humidity or very dry environments, however, glycerin may have the reverse effect, drawing moisture from the skin's deeper layers. Therefore, it's crucial to also include actives that hydrate the skin from “the inside” to eliminate this issue. 

With its occlusive characteristics, glycerin greatly helps people with dry skin since it creates a barrier on the skin's surface that blocks the evaporation of moisture. However, the occlusive nature of glycerin may clog pores and lead to breakouts for people with oily or acne-prone skin. Before selecting to add high levels of glycerin to your skincare product, it is important to evaluate your target’s skin type and the problems they are trying to solve.

In addition, glycerin may change the efficacy of other substances when combined with acids or alcohols. To get the best effects from your skincare routine, you need to pay close attention to the composition and compatibility of glycerin with other substances.

In conclusion, glycerin's moisturizing characteristics make it a popular component in personal care products. While it has many uses, it's important to weigh the pros against the drawbacks, which include skin irritation, reliance on humidity, occlusive qualities, component interactions, and individual preferences. As noted above, one of the best choices for advanced skincare is to combine glycerin with actives that help lock in internal moisture, help promote the production of hyaluronic acid and other glycosaminoglycans in-situ and increase the health of the Dermis and Epidermis to lock in moisture and lower TEWL (Trans Epidermal Water Loss).

Here at OpenBoxChemistry, we’ve taken a look at glycerin alternatives and synergist and would like to recommend the cosmetic chemist and marketing groups evaluate what we find are terrific raw materials.
