Active ingredient

Peptides

INCI · Palmitoyl Tripeptide-1

Peptides are short chains of amino acids used in skincare to signal fibroblasts toward collagen production, refine barrier, and visibly firm the skin. Different families act differently: signal peptides (Matrixyl), carrier peptides (copper-GHK), and neurotransmitter inhibitors (Argireline). Pair well with most actives. Apply at a different routine step from high-pH acid peels, which can cleave peptide bonds.

Pregnancy and breastfeeding

No specific caution is known for cosmetic use during pregnancy or breastfeeding. If you are unsure, ask your doctor or pharmacist.

Cosmetic peptide complexes are large polar molecules with minimal stratum corneum penetration. Mother to Baby and Trivedi et al. (2017) flag no concern for topical peptide use during pregnancy or lactation.

Mechanism in detail

What Peptides does

Short chains of amino acids that act as messengers in the skin. In anti-aging formulas they support the signals behind firmness and elasticity, softening the look of fine lines for smoother, more resilient skin.

Evidence

What the research says

  • 12 weeksFewer fine lines than the same moisturiser without it

    A double-blind split-face trial in 93 women aged 35 to 55: a moisturiser with palmitoyl pentapeptide, used for 12 weeks, reduced wrinkles and fine lines versus the same moisturiser without it, by image analysis and expert grading.

Where it helps

Concerns Peptides 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.

  • 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.

  • Dullness

    Dull skin is the visible loss of luminosity, where the surface appears flat, grey, or fatigued instead of light-reflective. The underlying causes are dead-cell accumulation on the stratum corneum, dehydration, microcirculation impairment, and oxidative stress. Effective treatment combines gentle exfoliation (alpha- and beta-hydroxy acids), antioxidant serums (vitamin C, niacinamide), barrier hydration, and consistent broad-spectrum SPF. Visible improvement typically arrives within two to four weeks of a structured routine, matching the natural cell-turnover cycle of healthy 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.

  • 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.
