Buyers note initial irritation requiring dose adjustment, which aligns with critics' observation that the product is gentle but some users experience sensitivity during adaptation.
In their words
“Buying Crystal Retinal serum is honestly one of the best decisions I’ve ever made for my skin. It’s the first time, after trying during so many years so many products, I can say that a brand like Medik8 fulfills what it promises. Today a friend that lives in other country texted me asking what I’m doing to have such a radiant and beautiful skin, just by seeing some pics I posted. I’m so happy!”

“I've been using the Crystal Retinal 6 for about a month now and I'm loving it! I jumped right in and started using daily but did notice after a few days a small bit of irritation so I then dialed it back to just using once a week and it was fine. Now using every other day and my skin is doing great!”
