MEDITHERAPY

Retinal Skin Booster Serum

For fine lines, uneven texture, and dull skin.

A retinal serum that breaks the usual rules of the category in two ways — it's gentle enough to use daily, and it comes in a generous 150ml bottle when most retinal products are rationed out in tiny 30ml droppers. That size matters: it reframes retinal from a "precious, careful-dab-at-night" active into a genuine skin booster you can apply liberally across the whole face. The retinal itself (retinaldehyde) is one conversion step closer to active retinoic acid than retinol, which makes it more potent — but Meditherapy encapsulates it in liposomes for stable, gradual, low-irritation delivery.

What makes it work for sensitive skin is the supporting cast. Around the retinal, the formula is built like a calming serum: a full Cica Biome complex (centella asiatica plus its TECA actives and centella-derived probiotics), ceramide NP and cholesterol for barrier support, niacinamide and a stable vitamin C derivative for brightening, plus beta-glucan, oat, and artichoke extracts for soothing. Non-comedogenic, passed skin irritation testing, and suitable for sensitive and acne-prone skin.

Best For: Anyone wanting to introduce a retinoid without the harshness — sensitive skin, retinol-intolerant skin, or anyone after fine line, texture, and pore care in a daily-use format. The large size also makes it good for full-face and neck application.

Key Ingredients
Retinal (Retinaldehyde, Liposome-Encapsulated) A more potent retinoid than retinol. One step closer to active retinoic acid. Encapsulated for stable, gentle, gradual delivery. Cica Biome Complex (Centella Asiatica plus TECA plus Probiotics) A full centella panel plus centella-derived probiotics that calm irritation and strengthen the barrier. The reason this retinal stays gentle. Ceramide NP and Cholesterol Two core barrier lipids that reinforce the defenses of the skin and offset the dryness retinoids can cause. Niacinamide and Vitamin C Derivatives A brightening pair (niacinamide plus stable ascorbyl tetraisopalmitate and sodium ascorbyl phosphate) that evens tone and works synergistically with retinal. Beta-Glucan, Oat and Artichoke Extracts A soothing, hydrating blend that keeps the formula comfortable for sensitive skin even with an active retinoid.
How to Use
After cleansing and toning, dispense an appropriate amount and gently pat across your face and neck (the generous size means you don't need to be stingy). Use at night to start. Follow with moisturizer, and always apply SPF the next morning — retinoids increase sun sensitivity. Tip: Even though this is gentle, ramp up slowly — 2–3 nights a week for the first couple of weeks, then build to nightly as your skin adjusts. And don't be tempted to use more just because the bottle is big; a thin, even layer is all a retinoid needs to work. More product means more irritation risk, not faster results.
