🌿 Key ingredients
MEDITHERAPY Retinal Skin Booster Serum 150ml Duo
Meditherapy Retinal Skin Booster Serum uses an encapsulated retinal, a next-generation retinoid known to act faster than classic retinol while remaining kinder to the skin. Its watery texture penetrates quickly and starts to refine surface texture, blur post-blemish marks and address early signs of aging within a few weeks.
The 150ml duo is designed for those already familiar with the formula and looking to secure long-term supply. Because the serum is gentle enough for daily use in most skin types, having two bottles ensures uninterrupted results across seasons and travels.
Koolseoul recommends this duo as a foundation of any modern K-beauty derma-cosmetic routine. Pair it with the Meditherapy Squalane Moisturiser to buffer sensitivity and with sunscreen every morning to protect your investment in smoother, brighter skin.
