If you're into skincare you most likely hear the same trio of products touted as the recipe for healthy skin: the best vitamin C serum, retinol and a daily facial sunscreen. The term ‘retinol’ is often used to refer to any derivative of the vitamin A spectrum (more on that later), and one product range that regularly tops the lists of the best retinols is Medik8 Crystal Retinal.

The CSA Philosophy Explained

Part of Medik8's derm-approved CSA philosophy (Vitamin C, Sunscreen, Vitamin A), Crystal Retinal Night Serum is one of several vitamin A-based products that Medik8 sells, and arguably its most famous. It uses an internationally patented delivery system, is clinically proven to deliver noticeable results, and is a favourite with beauty editors—including us at SkinShop.ie. Aside from its impressive youth-boosting effects on the skin, what makes Crystal Retinal so popular is how gentle it is.

Gentle and Effective

Using retinol-type products can often result in dryness, flaking, or increased sensitivity as new skin cells are regenerated and old ones are shed. Medik8 encapsulates its retinal (retinaldehyde to use its full name) in a slow-release ‘crystal’ technology, meaning maximum results with minimum risk of irritation. Medik8 reports that 97% of testers felt that their skin looked more youthful after using this serum for 12 weeks, with 100% also saying that it felt gentle. Crystal Retinal is available in five strengths ranging from 1 (0.01% retinaldehyde) to 20 (0.2% retinaldehyde), so there’s something for everyone, from vitamin A newbies to experienced users.

What is Retinal?

Contrary to popular belief, retinol isn't the only player in the vitamin A skincare game. Retinal, also known as retinaldehyde, sits closer to retinoic acid (the active form) on the vitamin A spectrum. When applied, enzymes convert retinal into retinoic acid, boosting cell turnover and collagen production for smoother, younger-looking skin.

Here's the key: all vitamin A derivatives (esters, retinol, retinal) need to convert to retinoic acid to work. Fewer conversion steps mean faster results. Retinal, requiring just one step, is 11 times faster-acting than retinol (two steps). While this translates to quicker rejuvenation, retinal's potency can also cause more irritation

How Should I Use Retinal?

Because retinal is more potent than retinol, it's important to start with lower concentrations and gradually increase your use to minimise potential irritation. Medik8’s ladder system makes this simple. We advise doing a patch test before applying any new retinal product, starting with every 2-3 nights before increasing usage. Apply to a clean face, avoiding the eye area, and follow with a moisturiser if needed.

Retinal can increase your skin's sensitivity to the sun, so it's crucial to apply a broad-spectrum sunscreen with SPF 30 or higher during the day. Consistency is key, so stick to your retinal routine even if you don't see immediate results.

The Crystal Retinal Range

The Crystal Retinal serum is available in five strengths, ranging from 1 to 20, ensuring there's a perfect option for everyone, whether you’re new to vitamin A or an experienced user.

This star ingredient helps to smooth skin texture and visibly reduce fine lines and wrinkles. Retinal also promotes a visibly decongested skin appearance. The groundbreaking Crystal Retinal formula works fast to deliver benefits showcased in an independent clinical study. With just one tube:
