Where it helps
Concerns Chronocyclin 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.
Sun Damage
Sun damage is the cumulative photoaging caused by ultraviolet radiation, presenting as solar lentigines, irregular pigmentation, fine lines, deeper wrinkles, leathery texture, and elevated skin cancer risk. UVA penetrates the dermis and drives collagen breakdown; UVB damages epidermal DNA and triggers melanin overproduction. Extrinsic factors, with UV exposure carrying the largest share, account for an estimated 80% of premature visible skin aging. Daily broad-spectrum SPF, antioxidant serums, and pigmentation correctors reverse early damage and prevent further progression. The BIOSAR Sunprotex range delivers broad-spectrum UVA + UVB protection layered with antioxidants for measurably stronger photoprotection.
