Active ingredient

Calendula

INCI · Calendula Officinalis Flower Oil (and separately Calendula Officinalis Flower Extract)

Calendula is a botanical extract from Calendula officinalis flowers, used in skincare to soothe inflamed, compromised, or post-procedure skin. Its triterpenoid faradiol esters and polysaccharides reduce erythema and support repair of the stratum corneum. 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 calendula is considered acceptable during pregnancy and lactation per Mother to Baby. Oral preparations are not recommended during pregnancy, but cosmetic surface use raises no documented concern.

Mechanism in detail

What Calendula does

Botanical with soothing properties, traditionally used on reactive skin. Delivered as oil and extract for complementary comfort and barrier support.

Evidence

What the research says

  • 41% vs 63%Skin reactions during breast-cancer radiotherapy

    A phase III trial in 254 women receiving radiotherapy after breast-cancer surgery: moderate-to-severe skin reactions occurred in 41% with a calendula ointment and in 63% with trolamine.

    A clinical study in patients, in a medical setting. It is shown for the science of the ingredient, not as an example of cosmetic use.

Where it helps

Concerns Calendula 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.

  • Sensitivity

    If you have sensitive skin, you have probably been told it is in your head — by a product that says "gentle" on the label, by a friend whose skin tolerates everything yours cannot, sometimes by a professional who could not find a visible cause for the symptoms. It is not in your head. The mechanisms are measurable, the biology is mapped, and the care that follows from understanding them is what the Sensimed range was built around.

  • 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.
