The Alpha Arbutin Discoloration Care Serum helps target hyperpigmentation to even out skin tone. So far I’ve noticed a big difference in how much brighter my skin looks and I’m excited to see some more of my dark spot lightening with time. The AHA BHA Blemish Treatment comes with cotton balls in a separate container to which you add the serum and then use the cotton balls for sport treatment. I’ve seen such an improvement in how quickly this product gets rid of breakouts. It is formulated with glycolic acid and salicylic acid. Sometimes strong acids can irritate my skin when applied all over the face so I love that these are for spot treatment, causing less irritation to the skin.
