The Everyone Vitamin A

Medik8 Retinal

Retinaldehyde (retinal for short) is a completely different vitamin A molecule to retinol. Don’t be fooled into thinking it’s just a misspelling of retinol! That one vowel change is small but the difference between retinol and retinal is quite stark.

Prescription strength without the prescription

Retinaldehyde is a relatively new vitamin A ingredient but still has significant published studies proving its efficacy: in particular, it is proven to be 11 times faster acting than traditional retinol. Read: faster results. However, it is notoriously difficult to stabilise. That’s why you won’t find it in many other brands. But Medik8 has managed it through a delicate crystal-shaped encapsulation system which breaks down on contact with the skin to slowly feed it over time. This is astounding since retinaldehyde is the closest thing to prescription-strength retinoic acid - the biologically active form on the skin. But now you obviously don’t need a prescription to get your hands on it.

The clever encapsulation system avoids any of the well-documented vitamin A side effects that can come with stronger formulations - flaking, redness etc. It also gives the product its name. Customers who try this vitamin A seem to universally adore it; as well as scores of influencers worldwide. One of our bestsellers for a reason. Take a look at the science behind it here.

Available in 5 strengths, we call it the ‘Everyone Vitamin A’ as it’s just that. If you’re in the market for a vitamin A, Crystal Retinal is for you. We recommend starting at strength 3 and working upwards if you want to boost results. (We only recommend strength 1 to those who are very sensitive).
