CERAPEP · CERAMIDES, PEPTIDES & DAILY COMFORTCYRÈNE · SINCE 2012
Cyrène began in Türkiye in 2012 with cosmetic chemist Shirin Koseoglu, MSc. Thousands of formulations later, our attention still moves between the science and the experience: the ingredients in a serum, the glide of an emulsion, the softness of a cream.
We bring that curiosity to encapsulated retinal, peptide serums and ceramide moisturisers. Our idea of everyday luxury is care you enjoy using and can afford to keep in your routine. Expertise in the formula. Pleasure in the ritual.
Our approach to skin longevitySKIN LONGEVITY, THE CYRÈNE WAY
A change of season. A drier-feeling week. A new evening ritual. Caring for skin over time means paying attention to what it needs today, too.
For Cyrène, skin longevity means looking after skin for the years ahead: moisture and barrier care, daily sun protection, and considered use of active ingredients. Our holistic approach connects these habits with a routine that feels good to use.
Your outer skin layer helps limit water loss. Humectants such as glycerin attract water; emollients such as squalane soften skin. Ceramides belong to the lipids naturally found in the barrier. These roles explain why a hydrating serum and a moisturiser can complement each other.
CeraPep brings ceramides, peptides and squalane to daily moisturising. Skin Rescue combines ceramides NP, AP and EOP with cholesterol, phytosphingosine and humectants.
Explore CeraPepExplore Skin RescueRetinal is a form of vitamin A used in skincare for visible signs of ageing. Diamond Retinal uses encapsulated retinal in a choice of concentrations. Introduce it gradually, leave room for moisturiser and adjust frequency to your skin’s tolerance. A higher percentage is a choice, not a milestone.
Compare retinal formulasUV exposure contributes to premature skin ageing. Daytime sun protection gives your routine a different kind of care: use a broad-spectrum SPF 30 or higher as directed, alongside shade and protective clothing. Retinal and antioxidant serums do not replace sunscreen.
