    How do I choose the right strength?

    Hi! I use the “Retinal + Niacinamide Youth Serum” from the brand “Youth to the People” which contains 0.15% stabilized retinaldehyde. I really like the product but I'm curious about Medik8 and their retinal, so I'm wondering which product I should choose from Medik8 considering what I'm using today? I would be very grateful for guidance!

      I understand! When I look, it seems like Medik8 Crystal Retinal 10 – contains about 0.10 % retinaldehyde, which is close to your current strength and a good alternative. If you want to start cautiously, choose Crystal Retinal 6 (0.06 %) and ramp up later. Tip: Introduce the product gradually anyway, even if the strength is similar – just a reminder that the formula differs between brands. Feel free to continue with soothing and moisturizing products in parallel. Hope this can help you a bit on your way and wish you good luck with your skincare😊

    Does it go together?

    Hi, I use Augustinus Bader The Cream and serum. Can I use this serum under the cream at night? Also, what strength should I start with? I have used retinol before but not Medik 8. Thanks!

      Hi Bettina Katalin😊 Thank you for your question✨ Since Augustinus Bader The Cream contains retinyl palmitate, which is also a vitamin A, I do not recommend using these at the same time. One vitamin A product at a time is sufficient, otherwise there is a risk of irritation and sensitivity in the skin. If you still want to use Medik8, I suggest using it on the evenings you do not use your Augustinus Bader The Cream. If you have used retinol before, I recommend starting with the lowest strength for Medik8 as it is powerful, i.e. 3, and start gently: 2 evenings/week, then gradually increase. Also, don’t forget sunscreen during the day. Always listen to your skin: if you see signs of irritation, redness, flaking → reduce the frequency. Hope the answer can be helpful and that you have a lovely day🌞

    Storage?

    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!

This product is not available in your market

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.
