Medicube Deep Vita A Retinol Serum offers next-gen retinol benefits without irritation, thanks to a 4th-generation liposome delivery system backed by 25 clinical tests. This antioxidant-rich serum visibly improves texture, post-acne marks, and fine lines while being gentle enough for sensitive skin (pH 6.3). Dermatologist-approved, vegan, and sustainably packaged, it’s the smart upgrade to traditional retinol.
