Who's It For

For vitamin A beginners and sensitive skin targeting the earliest signs of ageing who want a gentle but effective start.
Description

Medik8 Crystal Retinal 3 is a beginner friendly retinal night serum formulated with 0.03% stabilised retinaldehyde. Designed to visibly reduce fine lines and improve skin texture, it delivers fast acting vitamin A results with minimal irritation, making it the perfect entry point into the Medik8 Crystal Retinal ladder.

Encapsulated retinal is released gradually alongside hyaluronic acid, glycerin and vitamin E to smooth uneven tone, support hydration and improve comfort. Skin looks noticeably clearer and more renewed with consistent use.
How to Use

Apply two pumps to the face and neck in the evening after cleansing, then follow with a moisturiser. New users should apply twice weekly for two weeks, then every other night for two weeks, before moving to nightly use. Patch test first, and always wear SPF the next morning.

We use it at night after cleansing and pair it with Super C Ferulic in the morning, so a proper vitamin C sits under your SPF while retinal does its work after dark.
Ingredients

Retinaldehyde (0.03%): gentle fast acting vitamin A that smooths and renews.

Hyaluronic Acid: hydrates for a comfortable introduction.

Vitamin E: antioxidant support that conditions.

Please Note: For an accurate listing of ingredients in each product, please refer to your product packaging prior to use. SkinShop also recommend all products are patch-tested 24 hours before application.

So far, so good!

So far too early to tell proper results, but no dryness and the serum feels gorgeous on the skin - super silky and easily absorbed.
