Readers Love Medik8 Retinol For Being Gentle and Effective

Retinol has long been a skin-care staple, celebrated for smoothing wrinkles and refining texture. but often at the cost of redness and sensitivity. For years, that trade-off was considered worth it. But what if you didn’t have to choose between results and a calm complexion?

When we asked more than 400 NewBeauty readers* to name their favorite skin-care products, one retinol formula rose to the top: Medik8 Crystal Retinal 1 Serum.

Clinically proven to visibly smooth wrinkles, brighten dark spots, decongest pores and firm skin, this vitamin A night serum delivers impressive results without irritation. In a 12-week clinical study, users saw significant wrinkle reduction.

NewBeauty readers praised its gentle yet effective formula. A 32-year-old said, “I love their retinal. It’s gentle and effective.” Another, 47, simply called it “effective,” while others highlighted how well their skin responded to the thoughtful ingredient list.

The secret lies in Medik8’s use of retinaldehyde, a next-gen form of vitamin A that the brand notes works up to 11 times faster than traditional retinol. What makes it even more user-friendly: six progressive strengths tailored to every skin type and experience level. From Strength 1 (0.01%) for sensitive skin to Strength 24 (0.24%) for expert users, it’s easy to build tolerance and customize your routine.
