Do you ladies think its safe to use 5% concentration of lactic acid in a serum? I have used products in the past with 2% salicylic acid & they worked pretty well on my skin. Lactic acid is milder than salicylic acid so do you ladies think I can use 5% of it?

You could do a skin test on the inside of your arm to see if there's any reaction?
