What is Crystal Retinal

No, it's not a spelling mistake! Just when you think you know everything you need to know about Vitamin A or Retinol, Medik8 introduce another version of this anti-ageing wonder cream!

When it comes to anti-ageing, Vitamin A is the gold-standard. That being said, not all vitamin A is created equally.

Retinoic acid is the strongest form of Vitamin A on the market. It works rapidly to significantly combat signs of ageing, but it also comes with side effects – excessive dryness, peeling, redness and irritation, to name a few. For this reason, it is only available by prescription from a doctor or dermatologist.

So, if you're looking for an over-the-counter option, Retinol is the most popular form of Vitamin A you can get without a prescription. It also provides significant anti-ageing results. However, when applied topically, it must be converted into Retinoic acid by the skin before it can take effect, a process that requires a two step conversion.

This two-step conversion slows down the effect of Retinoic acid on the skin, which means less irritation, but it also means you have to wait longer before seeing results

And here's where Retinal enters! Medik8 researchers have harnessed the power of a form of Vitamin A that is even better than Retinol, and can be sold over-the-counter.

Present in their all-time best-seller Medik8 Crystal Retinal, this form of Vitamin A is a game changer in cosmeceutical skincare.

Why Crystal Retinal by Medik8 is such a game changer in the skincare industry

This powerful anti-ageing serum-cream has been formed with retinaldehyde, an advanced Vitamin A molecule that serves as the direct precursor to Retinoic Acid.

Because this advanced molecule only requires one step conversion to Retinoic Acid instead of two, it can can deliver results comparable to clinical-grade Vitamin A, up to 11x faster than classic forms of retinol. Even better, it remains as kind to the skin as traditional Retinol thanks to Medik8’s crystal-shaped encapsulation system. This is truly the next-generation of Vitamin A.

Which Crystal Retinal strength should I use?

If you are new to Vitamin A or looking to move up from a Retinol product, then starting with Crystal Retinal 1 or Crystal Retinal 3 would be a great start.

Once your skin aclimated to the strength of Crystal Retinal, then upgrading to Crystal Retinal 6 is your next step. From there you can either stay at 6 if you are happy with the results, or move up again to strength 10 of Crystal Retinal.

Superior Stability

Medik8’s crystal encapsulation acts as a time-release mechanism as well as a stability enhancer. Retinaldehyde is encased within a crystal-shaped molecular vehicle that is gradually broken down by the skin’s natural enzymes as the serum is massaged into the skin.

This unique action controls the release of the active to ensure the formula remains stable, absorption is optimised and the highly-potent formula is distributed evenly and consistently throughout the night.

Optinum Hydration

Featuring a nourishing blend of multi-weight Hyaluronic Acid, Glycerin and Vitamin E, Crystal Retinal can also:

  • Hydrate skin at every level
