Medik8 Crystal Retinal 24 is a very strong over-the-counter retinal serum, described as 20% stronger than the next equivalent strength. Board-certified dermatologist Dr. Sarah Sheu notes the brand offers six strength levels and a patented stabilization method, but warns the price increases with each step. Amanda Z, a beauty content creator, finds it "very strong" and says it might even be too strong for her, so cautious introduction is advised.
