Why choose Medik8 Retinal?
Medik8 Retinal works 11x faster than standard retinol. This means that you will see visible results faster: fewer wrinkles, a more even complexion and a firmer skin structure.
Thanks to the addition of hyaluronic acid, vitamin E and glycerin the formulas are not only powerful, but also exceptionally gentle. The skin is hydrated, soothed and protected, without excessive irritation. The patented one Crystal Retinal technology also ensures that retinaldehyde remains stable until the last drop.
Retinal vs. Retinol: What's the Difference?
- Retinal (retinaldehyde) is the direct predecessor of retinoic acid – the active form of vitamin A that stimulates the skin to renew.
- Retinol must first be converted into retinal and only then in retinoic acid. This makes retinol less powerful and slower acting.
| Feature | Medik8 Retinal | Traditional Retinol |
|---|---|---|
| Speed of operation | Works until 11x faster thanks to direct conversion to retinoic acid. | Slower, requires multiple steps into the skin. |
| Effect on the skin | Rapid improvement in texture, clarity and firmness within weeks. | Results visible after longer consistency (several months). |
| Irritation sensitivity | Low – Medik8 combines power with comfort thanks to soothing formulas. | Higher chance of redness and dryness, especially in sensitive skin types. |
| Stability | Exceptionally stable thanks Crystal Retinal-technology. | Sensitive to degradation by light and oxygen. |
| Frequency of use | Can be built up to daily use more quickly. | Requires longer adjustment period. |

What is the difference between Crystal Retinal and retinol?
Crystal Retinal contains retinaldehyde, a form of vitamin A that is one step closer to retinoic acid than retinol. This means that retinal works more directly in the skin and is often chosen when people want faster results, with a controlled build-up.
Which Crystal Retinal strength should I choose?
Beginners usually start with strength 1 or 3. Once tolerance has been built up, you can choose 6, 10, 20 or 24. The right choice depends on skin type, sensitivity and experience with vitamin A.
How do I build up Crystal Retinal safely?
Use the product in the evening, starting 2 to 3 times a week. Gradually increase the frequency as soon as the skin tolerates it well. During the day, a broad spectrum SPF is essential.
When will I see results from Crystal Retinal?
Many users notice a more refined skin texture and smoother appearance within 4 to 6 weeks. Consistent use and good sun protection are important for optimal results.
Is Crystal Retinal suitable for sensitive skin?
Crystal Retinal has been developed with supporting ingredients that help with skin comfort. For sensitive skin, choose a low strength and build up use slowly.
Can I use Crystal Retinal during pregnancy?
Products containing vitamin A, such as retinal or retinol, are not recommended during pregnancy. During that period, for example, choose:
Medik8 Bakuchiol Peptides as an alternative.
