Since Im very interested in serums in my 20s, I thougt this could be good for my entrance to serums, it claims the improvement for wrinkles, to prevent skin dry, controls the moisture and more whitening things.. It actually breakout severly my skin face, sever acne in my cheeks that actually never got in my life. Dont know if the products I combined with this serum are the reason D: totally looking for what caused this.
