Experts in Vitamin A
Retinol (vitamin A) is the gold-standard of anti-ageing. Highly regarded by dermatologists and skin therapists alike, it is second to none when it comes to improving signs of photoageing. As the experts in vitamin A, we understand its exceptional importance in the skin.
Anti-ageing like you’ve never seen it before
Vitamin A is able to stimulate cellular turnover in the skin, pushing fresh skin cells to the surface for a smoother, youthful-looking complexion. This helps to unclog pores for a blemish-free complexion. Vitamin A also enhances collagen production to combat fine lines and wrinkles, and helps block the formation of pigment in the skin for brighter, more even-toned skin.
However, let’s just say it… Vitamin A has its issues. When delivered at levels high enough to have a visible effect on skin ageing, it can cause irritation in the form of stinging, redness and peeling. So we decided to do something about it.
The side effects of retinol are often associated with too much of the active being delivered too quickly. To counteract this, Medik8 developed a unique Time Release (TR™) delivery system. All of Medik8’s vitamin A serums use the active encapsulated in a micro-fluid or polymer shell. As the serum is rubbed into the skin, the encapsulation breaks down and the vitamin A is slowly released into the skin. This significantly minimises the risk of irritation and ensures that skin benefits are received slowly over a prolonged period of time. That’s why we consider all our retinol products: “intelligent retinol”.
At first, start with an entry level strength product, such as Retinol 3TR™ twice a week for the first 2 weeks, then once every other night for a further 2 weeks and then nightly application. Once your skin has built up a tolerance to the ingredient, you can then move on to a higher strength vitamin A.
Medik8 has a range of vitamin A products to suit every skin type and need. We don’t use traditional retinyl esters (such as retinyl palmitate) because they are very weak and poorly absorbed by the skin. Instead, we focus all our attention on forms of vitamin A that are scientifically proven to provide great results. Take a look at the comparison table below.
You can be confident that our entry-level vitamin A is better than many competitors’ highest level.
We focus our attention on forms of vitamin A that are clinically proven to provide results
The classic form of vitamin A. Tried and trusted in numerous dermatological journals, retinol is the form of vitamin A that makes the headlines. When retinol is applied to the skin, it undergoes two conversions. First, it is converted to retinaldehyde and then to retinoic acid. Retinoic acid is the active form of vitamin A; the form that can actually be utilised by the skin. It triggers cellular renewal and collagen production to give the amazing effects experienced by retinol users. We have a comprehensive retinol product collection, ranging from Night Ritual Vitamin A™ (0.2%) for absolute beginners, to maximum strength Retinol 10TR™ (1%) for experienced vitamin A users.
With innovation at our core, we just weren’t quite satisfied with our range of intelligent retinol serums. We decided to take vitamin A to the next level and introduce retinaldehyde – a next generation vitamin A molecule which is one step closer to retinoic acid than retinol. Delivering results up to 11 times faster than classic forms of retinol in Crystal Retinal™,1 retinaldehyde rapidly resurfaces the skin while helping rebuild collagen. Delivered in a crystal encapsulation system, the active is time released throughout the night. This means retinaldehyde is just as gentle on the skin as retinol, but has effects similar to prescription-strength retinoic acid. Unlike the other forms of vitamin A, retinaldehyde boasts direct antibacterial action, making it the ideal anti-ageing ingredient for blemish-prone skin. Available in four different strengths, start with Crystal Retinal 6™ or Crystal Retinal 3™ to get your skin used to the new vitamin A, using the retinal ladder, and then move up to Crystal Retinal 10™ when your skin is ready. For sensitive skin, we also have gentle-strength Crystal Retinal 1™.
A true breakthrough in anti-ageing skincare, this innovative active was the result of 8 years of research in collaboration with a Korean superlab. Retinyl retinoate is a hybrid molecule which fuses retinol and retinoic acid. Patented worldwide and exclusive to Medik8, this encapsulated new molecule exhibits properties of both source ingredients; improving the anti-ageing activity of retinol without the irritating side-effects of retinoic acid. Found in r-Retinoate®, it increases collagen production and wrinkle repair by up to 8 times more than standard retinol.2 Plus, unlike many other vitamin A derivatives, retinyl retinoate is much more stable in sunlight, meaning remarkably it can be used day and night for accelerated results.

As a general rule we say start on a strength lower than you were using from another brand. Unfortunately we do not know how stable the other brand’s retinol serum was; what was labelled as 1% retinol may actually be equivalent to a much lower concentration of retinol if it has degraded. Therefore, to stay on the safe side, we would recommend go lower in strength with our stabilised retinol serums to ease your skin into using them, and avoid irritation.
What percentage of retinol were you using in the other brand?
Don’t know - start on Retinol 3TR Intense
0-0.6% - start on Retinol 3TR Intense
0.7-1% - start on Retinol 6TR Intense
If Retinal - start on Crystal Retinal 3
If Retinyl Retinoate - start on r-Retinoate Day & Night or r-Retinoate Intense
In general we recommend that new users of Crystal Retinal start with Crystal Retinal 3.
This is an effective, but relatively lower strength of retinaldehyde, to give your skin an opportunity to adjust to the new vitamin A molecule.
There are a couple of exceptions depending on which retinol product you are currently using. Here is our guide:
If you have very sensitive skin -> Crystal Retinal 1
Night Ritual Vitamin A -> Crystal Retinal 3
Retinol 3TR/Intense -> Crystal Retinal 3
Retinol 6TR/Intense -> Crystal Retinal 3
Retinol 10TR/Intense -> Crystal Retinal 6
If you have sensitive skin - Crystal Retinal 1, Night Ritual Vitamin A, r-Retinoate Day & Night If you do not have sensitive skin - Crystal Retinal 3, Retinol 3TR Intense, r-Retinoate Day & Night or r-Retinoate Intense
Every time you start on a new molecule of vitamin A (eg. switching between Intelligent Retinol and Crystal Retinal).
Except when switching to r-Retinoate Day & Night, which is so gentle it doesn’t need to be phased in.
You do not have to phase in when moving up strength in the same vitamin A ladder (eg. moving from Crystal Retinal 3 to Crystal Retinal 6).
If moving from Intelligent Retinol to Crystal Retinal - phase in
If moving from Crystal Retinal 3 to Crystal Retinal 6 - don’t need to phase in
If moving from Intelligent Retinol/Crystal Retinal to r-Retinoate Day & Night - don’t need to phase in
If moving from Intelligent Retinol to r-Retinoate Intense - phase in (due to retinal content)
If moving from Crystal Retinal to r-Retinoate Intense - don’t need to phase in (same molecule retinal)
r-Retinoate Intense is a nourishing cream formulation, which contains lots of emollients, squalane and ceramides, which minimise its potential for irritation on the skin, in comparison to Crystal Retinal 6 which is a lighter cream-serum. It also contains 3 types of Time Release Technology; polymer-encapsulated retinyl retinoate, crystal-encapsulated retinaldehyde, and polymer reservoir technology. All three modes of Time Release minimise the irritation potential for r-Retinoate Intense, and we are confident that most skin types will be able to phase this into their skincare routine without issue.
