I’ve been using vitamin A before from another brand, what should I move onto in Medik8?
As a general rule we say start on 1 strength lower than you were using from another brand. Unfortunately we do not know how stable the other brand’s retinol serum was; what was labelled as 1% retinol may actually be equivalent to a much lower concentration of retinol if it has degraded. Therefore, to stay on the safe side, we would recommend going lower in strength with our stabilised vitamin A serums to ease your skin into using them, and avoid irritation.
What percentage of retinol were you using in the other brand?
Don’t know - start on Retinol 3TR
0-0.6% - start on Intelligent Retinol 3TR
0.7-1% - start on Intelligent Retinol 6TR or start on Crystal Retinal 3
If retinyl retinoate - start on r-Retinoate Day & Night or r-Retinoate Intense
