Rough, sandpaper-like cheeks are a top routine question right now. A two-week lactic acid and ceramide trial shows what actually moved the needle, and where its limits are.

A common complaint in skincare forums right now: cheeks that feel like fine sandpaper even after a gentle routine is in place. The instinct is to scrub harder or add another acid. The research that exists points the other way: rough texture is most often about scale that has not shed evenly and water that is not being held in, and the fix that was actually measured combined mild exfoliation with moisture, not more abrasion.
Rough, sandpaper-like skin is typically a surface issue: dry flakes and uneven shedding of the outermost layer, which catch the light and the fingertip. Dermatology trials score this directly. One lactic acid trial rated tactile roughness, visual roughness, flakiness and luminosity on a 0 to 4 dry skin scale, which shows that clinicians treat roughness as a measurable cosmetic attribute and not just a feeling. That framing helps because it separates two questions: how much dead scale is sitting on the surface, and how well the skin is holding water.
The most useful published data point we found is a randomized, evaluator-blinded study of 56 healthy women aged 50 and older with dry, rough shins (grade 3 to 4). One shin received a lotion containing lactic acid, glycerin and a ceramide blend twice daily for 14 days, and the other shin was left untreated.
The numbers were large for a two-week study:
Important limits: the lotion was funded by its manufacturer, two authors were employees of its parent company, and the test site was the shin, not the face. The authors also list the short duration, single site and limited diversity as weaknesses, and the trial did not compare against other moisturizers. So the result supports a lactic acid plus humectant plus ceramide approach for rough dry skin on the body. It does not show that the same product would look the same on cheeks.
The trial authors state that lactic acid by itself does not relieve dry skin and needs to be formulated with an occlusive to keep water in the outer layer. This is the piece many routines miss. If you add an exfoliating acid to a thin, watery moisturizer, you may remove scale and still be left with a surface that dries out by afternoon. Pairing a mild acid with a cream that contains glycerin and ceramides, as in the test lotion, matches what was studied.
A separate hairless-mouse study compared creams with and without hydroxy acids. Only glycolic acid and lactic acid significantly increased stratum corneum thickness, which the authors read as exfoliation in progress, and no inflammation was evident. The authors also noted that acid esters at pH 4.5 to 5.0 were less effective than the free acids. This is animal tissue under a microscope, so use it for mechanism, not for predicting how your cheeks will respond.
Rough skin tempts people to exfoliate daily. Four board-certified dermatologists quoted by Prevention in August 2025 did not recommend daily exfoliation for any skin type. Their ranges were once or twice a week at most for dry or sensitive skin, two to three times weekly for oily skin, and once or twice weekly with mild products for mature skin. They list redness, stinging, tightness, cracking or peeling and breakouts around the cheeks and mouth as signs you have overdone it, and note that reactions can take a day or two to appear.
Overdoing it creates a loop: stripped skin flakes, flakes feel rough, and rough skin invites more scrubbing.
If the texture persists after a month, or if your skin is itchy, painful or changing, talk to a dermatologist.
For sandpaper cheeks, the evidence points to less friction and more water retention. The best-measured approach in our sources was a mild lactic acid combined with glycerin and ceramides, with exfoliation capped at one or two nights a week and daily sunscreen on top. Treat the shin trial as encouraging but limited, and judge your own result by how skin feels and looks after two weeks, not after two days.
