    Hi! Do you know if this needs to be stored in the fridge or if it’s okay at room temperature? 😊

      Hey Liviana-Elena! You don't need to store this in the fridge! It thrives best at room temperature, as long as it stands in a cool and dark place, like in a bathroom cabinet or drawer. It helps protect the sensitive retinaldehyde from light and heat Take care!

Rediscover youthful skin with Crystal Retinal 6™, Medik8’s latest innovation in vitamin A. Formulated with 0.06% stabilised retinal, a powerful derivative of vitamin A with next-generation anti-ageing results. Unmatched in its age-defying power, retinal can deliver results comparable to clinical-grade vitamin A up to 11 times faster than classic forms of retinol. The ground-breaking overnight serum visibly minimises fine lines and wrinkles; firming and plumping the complexion to resurface skin texture and soften the face. Featuring hyaluronic acid, glycerin and vitamin E, it hydrates skin at every level to deliver a supple, even-toned, more youthful-looking complexion. More than that, it actively helps reduce blemish-causing bacteria to keep skin clear and balanced. In just 4 weeks, skin is noticeably younger, smoother and undeniably radiant.

Crystal Retinal 6 is perfect for those who are new to vitamin A or who are looking to upgrade their retinol results.
