I am the perfect candidate for this product as I have skin that is both aging and is also prone to breakouts and blackheads. Since I have been using the serum, the sebum level of my skin has been under control so it has cleared up my blemishes and prevented the start up of further breakouts. Not only does it target blemishes/acne but it simultaneously works on your fine/lines and wrinkles and any discoloration/sun damage your skin has. I love the dropper type application and the formula is completely non-oily. The formula includes salicylic acid which is the hero ingredient behind the blemish control, as salicylic acid penetrates the pore lining and exfoliates inside the pore and on the surface of the skin and prevents breakouts and reduces acne & blackheads etc. The hero behind the resurfacing of skin/wrinkle reduction and the discoloration reduction is the glycolic acid and citric acid (the AHA's) This is one powerful and potent treatment for aging skin with imperfections! It is recommended to use once or twice a day, expect a little tingle for the first couple of days.
