Beginner-Friendly Retinaldehyde Serum for Face & Body | Korean Skincare
The MEDITHERAPY Retinal Skin Booster Serum is a next-generation K-beauty retinal serum designed especially for beginners and sensitive or blemish-prone skin. Using retinaldehyde (retinal)—a more advanced form of vitamin A—this lightweight, non-irritating formula delivers faster visible results than traditional retinol, without discomfort.
Manufactured by KOLMAR KOREA CO. LTD, this large-size serum is suitable for both face and body, making it a versatile staple in any skincare routine.
⭐ Why This Retinal Serum Stands Out
✨ Beginner-Friendly Retinal Technology
- Uses retinaldehyde, a next-generation retinoid
- Works up to 11× faster and 3× more potent than retinol
- Delivered via nano-liposome technology for controlled, gentle absorption
- 0.00 irritation index with no artificial coloring
✔️ Ideal for first-time retinoid users

All with greater efficiency and less waiting time than retinol.
