Active ingredient
Glycolic Acid
INCI · Glycolic Acid
Glycolic Acid is the smallest alpha hydroxy acid, valued for gentle surface exfoliation. It helps loosen the bonds between dull surface cells so they shed more readily, revealing a smoother texture and a brighter, more even-looking tone over regular use.
Mechanism in detail
What Glycolic Acid does
It weakens cohesion between surface cells, encouraging gentle exfoliation and visible surface renewal.
Where it helps
Concerns Glycolic Acid addresses
Aging
The first time you notice it is rarely a wrinkle. It is a quality of light — the way your skin catches it differently in a morning mirror, or the photo where you look more tired than you feel. The mechanism is real (collagen synthesis slows; elastin fragments; barrier turnover lengthens), but the felt experience comes first. Serenity Age is the range BIOSAR built for that pivot — Retinol for visible renewal and collagen support, peptides selected for documented signaling activity, and the SPF discipline that protects every other active you apply.
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.
