Are fine lines becoming deeper, does your skin texture feel uneven and does pigmentation linger? Then Medik8 Crystal Retinal 10 – the potent vitamin A serum from the Crystal Retinal ladder – is the logical next step. With 0.1% retinaldehyde this is an advanced strength: for anyone who tolerates Crystal Retinal 6 daily and wants to keep building visibly smoother, firmer skin. Suitable for all skin types, provided you build up gradually.

How it works

Retinaldehyde (retinal) is the form of vitamin A that works up to 11 times faster than traditional retinol, because the skin needs fewer conversion steps. It stimulates cellular renewal and collagen production, visibly reducing fine lines, wrinkles and pigmentation. Sodium hyaluronate holds on to moisture, squalane and glycerin support the skin barrier, and tocopheryl acetate (vitamin E) acts as an antioxidant. That keeps the formula gentle, even at this higher strength.

Texture and use in your routine

A light, creamy serum texture that absorbs quickly and has a subtle, soft scent. Crystal Retinal 10 is the A step of the CSA routine and is used in the evening only, after cleansing and before your night cream. Pair it with Advanced Night Restore for overnight renewal and Hydr8 B5 for extra hydration. Mornings always call for vitamin C (such as C-Tetra) and an SPF 30 or higher, for example Advanced Day Ultimate Protect SPF 50+. Avoid the immediate eye area and pause temporarily if irritation occurs.

Frequently asked questions

Is Crystal Retinal 10 suitable as a first retinal?

No, start with a lower step such as Crystal Retinal 1 or 3 and work up through 6. Strength 10 is intended for advanced users who tolerate step 6 daily.

Can I combine it with vitamin C?

Yes, but separately: vitamin C and SPF in the morning, Crystal Retinal 10 at night. That is exactly the Medik8 CSA philosophy.

How long does 30 ml last?

Using 2-3 drops each evening, a 30 ml bottle generally lasts several months with daily use, and longer during the build-up phase.

Crystal Retinal 10 works with 0.1% retinaldehyde, a form of vitamin A that acts up to 11 times faster than traditional retinol because the skin needs fewer conversion steps. It stimulates cellular renewal and collagen production, visibly reducing fine lines, wrinkles and pigmentation while refining skin texture. Sodium hyaluronate binds moisture, squalane and glycerin support the skin barrier and vitamin E works as an antioxidant. This keeps a high strength comfortable to use, without extreme irritation.

Use Crystal Retinal 10 in the evening only. Apply 2-3 drops to cleansed, dry skin and spread over face and neck, before your night cream. Avoid the immediate eye area. Start every other evening and gradually build up to daily use. Pause temporarily if irritation occurs. Always use vitamin C and an SPF 30 or higher during the day.

After a few weeks skin feels smoother and fine lines look softer. With consistent use the texture becomes more even, skin appears firmer and pigmentation visibly fades. Mild dryness can occur during the build-up phase and usually settles once your skin has adjusted.
