Maskne is one of the most common skin problems lately, even if I'm a certified esthetician, and I'm used to working with a mask on my face, my skin didn't go through mask season well. Thanks to Bioderma's campaign I found a dermatologist who recommended me to try Aklief - a new generation of retinoid, and since it's a new treatment, I want to share with you few tips which I wish I knew when I started to use Aklief.
