KEY INGREDIENTS
Retinaldehyde
Proven to work up to 11x faster than standard retinol,[1]retinaldehyde (retinal for short) is a revolutionary retinoid that effectively targets the appearance of fine lines and wrinkles, dark spots, uneven skin texture and loss of firmness - without irritation.
Hyaluronic Acid
With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the skin. This leaves the complexion visibly nourished and supple.
Vitamin E
A powerful antioxidant that's naturally present in the skin, Vitamin E works to nourish the complexion.
Glycerin
A natural humectant which traps moisture within the skin to leave it hydrated and comfortable.
THE SCIENCE BEHIND THE FORMULA
When it comes to retinoids; the more stable the molecule, the more effective it can be on the skin. Crystal Retinal serum offers a level of retinal stability that can only be found at Medik8.
Our innovative stability system features our renowned crystal encapsulation technology, a patented carrot seed oil complex, and airless packaging. All this comes together to protect the retinal molecule for unmatched potency, long-lasting effectiveness and proven skin comfort.
Unlike many retinals, which can cause flaking and irritation, Crystal Retinal has been expertly formulated in our in-house laboratory with a unique combination of the highest quality ingredients and patented technologies so it's gentle yet very powerful.

Why are Crystal Retinal 20 and Crystal Retinal 24 peach-colored?
Why are Crystal Retinal 20 and Crystal Retinal 24 peach-colored?
The bright peachy tone of Crystal Retinal 20 and Crystal Retinal 24 is a combination of the natural yellow color of the retinal, and some natural extracts which shift the color from yellow to a more peachy tone. Crystal Retinal 20 and Crystal Retinal 24 are brighter than the lower strengths of Crystal Retinal due to their higher concentration of retinal.
Will Crystal Retinal 20 / Crystal Retinal 24 stain my bedding, pillows, or pajamas?
Will Crystal Retinal 20 / Crystal Retinal 24 stain my bedding, pillows, or pajamas?
Crystal Retinal's peachy tone gets more intense as you go up the ladder and may create a peachy tone on the face or potentially transfer onto bed sheets. Color left on bedsheets can be mitigated by allowing Crystal Retinal to absorb fully and dry before making contact with light- colored fabrics (such as pajamas, bedding, or pillows). We would also recommend applying a moisturizer over the top of Crystal Retinal 20 / Crystal Retinal 24 to seal it in. If sheets are left with color on them, wash at 30 degrees and leave to dry in the sunlight - retinal degrades in the sun which helps the color to quickly fade away.
