4. MEDICUBE Deep Vita A Retinol Serum

Medicube is a powerhouse in Korean skincare, and with its new AGE-R device, it’s leading the charge in home care innovation. But today, let’s focus on a must-try product for retinol newbies: the Deep Vita A Retinol Serum.

What makes this serum stand out? It’s packed with 4th-generation retinol (HPR), which is gentle on the skin yet highly effective in fighting wrinkles.

7. AESTURA Retinoid Eye Serum

The skin around your eyes is the thinnest and most delicate on your face, making it highly sensitive to irritation.
