GEEK & GORGEOUS A-Game 20 Anti-Wrinkle Serum with Retinal 0.2% and Ectoine 30 ml

User Instructions / Warnings: Evening care: Apply a small amount of serum (about a pea) to dry, cleansed facial skin, avoiding the eye area. Frequency of use: At first, use the serum 2-3 times a week to allow the skin to get used to the effects of retinal. Over time, you can increase the frequency to daily use if the skin responds well to the product. Sun protection: During the day, always use a cream with SPF 30 or higher, as retinal increases the skin's sensitivity to UV radiation. Combining with other products: You can use the serum alone or combine it with other moisturizing products. However, avoid using it at the same time as strong acids and other retinoids.
