Medik8 Crystal Retinal 10 ingredients: is it worth it?
A genuinely potent retinal serum buried in an expensive, fragrance-allergen-containing luxury base—not a miracle, but one of the stronger over-the-counter vitamin A formulas.

READ MORE
The efficacy score is driven primarily by retinal listed in a dedicated treatment position and supported by encapsulation technology, with additional but secondary support from sodium hyaluronate and emollients. The advertised 0.1% retinal concentration is meaningful for experienced users, while the vitamin C derivatives sit lower in the list and should not materially drive the score. The formula does not disclose a pH, so acid-dependent vitamin C performance cannot be confidently credited, and the botanical/fragrance components add complexity without proven anti-aging value. Medik8 identifies Crystal Retinal 10 as a 0.1% retinal serum for advanced vitamin A users.
