    Powerful Retinal

    In my opinion, the best retinal there is. Have tried others but have come back to this one. Pores, blemishes, and fine lines have reduced. Better skin tone and radiance. Also very gentle on the skin. #lykoreview

    Retinol-retinal

    I have been using retinol for a good while and have robust and normal skin that can tolerate a lot. I have some fine lines and volume loss which are my main challenges (I am 38 years old). I have been using Bioterm Blue retinol serum for a long time now, and I tolerate it well. I want to test something with a bit more kick. What could be a good next product?

      Hi Marthe 👋 This product is actually a really good "next step" if you want more effect than regular retinol 🤩 Medik8 Crystal Retinal 10 Serum contains 0.1% retinaldehyde (retinal). It is a different type of vitamin A than retinol. Retinal is one step closer to the active form. This means that retinal can work significantly faster and more effectively than classic retinol, because it requires fewer conversions in the skin 🧬 Medik8 also states that retinal can deliver results up to 11× faster than standard retinol. That’s why many choose retinal when they want to upgrade their retinol routine 🙌 You mention fine lines + volume loss. Retinoids are one of the few ingredients that can actually affect this because they: -increase collagen production -improve skin texture -reduce fine lines -even out pigment and skin tone Tip 👇 Even if your skin is robust, do this for the first 2–3 weeks: -week 1–2: every other night -week 3: daily if the skin feels good -use good moisture + SPF This helps you almost always avoid retinoid irritation ❤️

    Cream or serum?

    Hi, the product is called Cream but the picture and reviews refer to the serum I'm looking for. Just wanted to double-check that it refers to the Crystal Retinal serum 10 product?

      Hi Ava😊 Thank you for being attentive🤍 I will take it further right away so that it doesn't get confusing and is correct in the name, i.e. serum also here on our website. The reviews refer to this serum anyway, so you can feel at ease regarding that. Hope the answer can be helpful and that you have a lovely day💫

    Strength Choice

    Hi, If someone has used Retinal 3 and hasn't experienced any irritation, should they switch to this next? Or how would you recommend proceeding with strength, since they are only using this brand?

      Hi Annemari ✨ Great question! After Retinal 3, it is recommended to switch to 6-strength, and then you can move to 10-strength! Even though the skin is well accustomed to 3-strength, it's a good idea to start trying the next strength gradually to avoid skin irritation 🥰

    What strength?

    I'm using Geek & Gorgeous A-Game 10 0.1% Retinal Serum today. What strength of Medik8 Retinal do you recommend then?

      Hey Hanna! If you're already using Geek & Gorgeous and tolerating it well, Medik8 Crystal Retinal 6 would be good to switch to (start slowly and feel it out since it's a different type of formula). Take care 🤗

    The real elite product in its class!

    Over-the-counter retinoid products are absolute elite and honestly my favorite products among all skincare products. This retinaldehyde product has not irritated my skin even with frequent use, as retinol products sometimes do. Very pleasant texture and a mild, pleasant scent (usually I would give minus points for fragrance, but in this product it didn't bother me at all). The gradually increasing strengths in the product are an excellent thing, easy to switch to a milder version during the brighter times of the year and back to a more effective treatment when desired. Expensive product, but worth the money and also quite economical.

Main ingredients
RETINAL/RETINAL DEHYDE:
This is the next generation form of vitamin A that works 11 times
faster than retinol. Retinaldehyde enhances collagen production,
accelerates cell renewal and inhibits pigment production for one
youthful skin with an even tone. Retinal is also antibacterial and
counteracts Propionibacterium acnes which causes acne
HYALURONIC ACID:
Hyaluronic acid has a unique ability to attract and retain more than 1,000 times its own weight in water and draws moisture from the surrounding
the air and the lower skin layers to the top layer of the epidermis. Hyaluronic acid with different molecular weights is used consistently in Medik8's products. When molecules
with different weight used together they distribute the moisture in all skin layers for a soft and supple skin
VITAMIN C:
Antioxidative effect that counteracts the free radicals that occur in
UV radiation and fights visible signs of aging
Vegan (certified by The Vegan Society as formulated without ingredients or by-products of animal origin) formula.
