My skin care faves currently Every mornig i start with a vitamin c serum, it is important that you get one with more than 10% Vit C. I use Retinol every evening, since my serum is with a very low concentration (0,2%). If you are using retinol for the first time i recommend using it every 2-3 days so that your skin gets used to it, and after that increasing the concentration or the frequency. It is really important that you also use SPF with the Retinol serum!!!!
