AmLactin for chicken skin: what to know

Lactic acid loosens compacted surface cells while helping skin retain moisture. That combination may flatten the rough feel around follicle openings, although the bumps can return when treatment stops.

Keratosis pilaris commonly presents with small, firm, rough bumps on areas such as the upper arms or thighs. Folliculitis can also cause bumps, but these are more likely to be tender, itchy, pus-filled or centred on an inflamed hair follicle. Lactic-acid lotion is not a substitute for treating an infection.

Redness around otherwise rough plugs may become more obvious if too much acid is used. Picking and squeezing can damage follicles and produce lingering marks.

Try the lotion on a limited patch of unbroken skin and use it as directed on the label. If comfortable, build a consistent routine rather than applying a thick layer. Skip it after hair removal when the area feels raw or has tiny cuts.

Use lukewarm water, a mild cleanser and light pressure when drying. Avoid grainy scrubs and do not combine several acids on the same evening. Sun protection matters when treated areas are exposed outdoors.

Have the area checked if bumps are painful, hot, draining pus, crusted, rapidly spreading or leaving scars. Stop the lotion for blistering, pronounced burning or swelling. Trouble breathing or swelling of the lips, tongue or face requires urgent medical help.

Ask whether the appearance fits keratosis pilaris, folliculitis, ingrown hairs or eczema. A dermatologist can also explain whether lactic acid suits the affected body site and what to use if redness, itch or follicle inflammation is the main concern.
