Active ingredient
Glycerin
INCI · Glycerin
Glycerin is a small triol humectant used in nearly every category of skincare to draw water into the stratum corneum. It binds water molecules at the cell surface, plumps the look of the skin, and supports barrier recovery in dry or compromised conditions. Pairs broadly with most actives. No major conflicts.
Pregnancy and breastfeeding
No specific caution is known for cosmetic use during pregnancy or breastfeeding. If you are unsure, ask your doctor or pharmacist.
Topical glycerin is considered safe during pregnancy and lactation per Mother to Baby and Trivedi et al. (2017). It is one of the most universally tolerated humectants in cosmetic use.
Mechanism in detail
What Glycerin does
Humectant that attracts water to the skin. Core hydrating ingredient across face, body, and baby formulas.
Evidence
What the research says
- +59%Hydration up 59% one hour after a three-active fluid
In 20 women, one application of a fluid with hyaluronic acid, glycerin and a Centella extract raised forearm hydration by 59% at 1 hour, 48% at 8 hours and 29% at 24 hours versus an untreated site. Glycerin was one of three actives.

Where it helps
Concerns Glycerin addresses
Dryness
Dryness is a barrier dysfunction in which skin loses water faster than it can retain or replenish it, presenting as flaking, tightness, dullness, and roughness. Mild dryness reflects routine over-cleansing or environmental exposure; chronic dryness signals a deeper deficit in skin lipids (ceramides, cholesterol, fatty acids) and humectant content (the natural moisturising factor). Effective treatment hydrates and replenishes the barrier through three layered actions: humectants that draw water in, occlusives that seal it in, and barrier actives that rebuild the lipid mortar. The BIOSAR Hydraderm range delivers this layered hydration and visibly plumps dehydrated skin.
Hyperpigmentation
Across Fitzpatrick III–V skin tones — the majority of darker skin tones — the most common consultation is the same: the patch on the cheekbone that did not fade. Melasma, post-inflammatory hyperpigmentation, the marks that follow acne and friction. The pattern is photoresponsive, the mechanism is mapped, and visible improvement is reachable with consistent care. The Whitepurity range is built for that work — Alpha-Arbutin for stable tyrosinase inhibition, Niacinamide-led brightening, and the SPF discipline that decides whether any of the rest will hold.
