Retinol is suitable for all skin types, from sensitive, anti-aging to acne prone skin types. Many retinols are fairly potent and take a little bit of time for the skin to get used to it. Frequency of use can be adjusted till the skin gets acclimated to the potency of this serum. Our Emerge night serum is a great serum for those who are used to using Retinols or people that are new to the ingredient Retinol. It is also a great one for sensitive skin types.
