The Ordinary Lactic Acid 10% + HA 2% High-Strength Exfoliating Serum for Uneven Texture - 1 fl oz - Ulta Beauty

A: I think it evens up your skin tone. Hyperpigmentation would be an example!

A: In MY personal experience, for the first 1-2 weeks, it can seem yo cause additional bumps/pimples to form -- it seems to help "purge" your skin. For me, after two weeks of nightly use, my skin was much more smooth to the touch, had far, far less clogged pores, especially on and around my nose and unlike previous mild acid exfoliants, I didn't walk around with a red face for weeks. After repeated, lonterm use (6+ months), it has given me a much more clear, smooth AND even-toned complexion. I don't know the right skincare-type words to describe it, but it has made even my naked skin --like just stepping out of the shower before putting even a single skincare product on my face -- it has made my skin feel so smooth to the touch. For quite some time, I have had a small pea-sized "rough patch" near my rightside temple and another near the the hollow of my left cheek -- both felt rough to the touch and no amount of moisturizers and repeated "apricot scrubs"* helped. After using this lactic acid for just once a day for a month, those two rough, dry and darker-pigmented areas have quite literally disappeared.

A: Initially, I'd suggest every other night for 10-14 days (every 3rd night for sensitive skin), and if you have no sensitivity to it, every evening thereafter.

A: It would be a pricey endeavor to use all over your scalp as it would need to be done for several consecutive days. I would suggest using a scalp scrub instead AS this may eventually damage the hair by making it more porous - scalp scrubs can be pricey for the amount of product. So, I suggest you look into a homemade scalp scrub that contains table salt or white sugar granuals to use to scrub the scalp areas that need exfoliating -- a rubber-bristle based scalp brush would likely improve results -- oh, and don't fork over an enormous amount for a rubber scalp brush -- just buy one at a pet store for a significantly lower price AND you can select the firmness of the rubber brustles. You may want to mix the salt or sugar into a paste with dandruff shampoo + a drop of water and use that to dry-rub on your scalp and use it again after fully wetting your hair. I definitely would not use this as a daily or even weekly topical to the scalp as it may cause damage to the hair -- that won't show up until a few weeks of use. Even if cost was of no concern and you could purchase 4 bottles of this lactic acid every week to use on your scalp I think the damage it would do to your hair over time would not be welcomed. That's just my two cents.

A: It can appear foamy or bubbly when applied vvigorously. To minimize this, try patting it onto the skin instead of rubbing.
