LHA (lipohydroxy acid, a capryloyl derivative of salicylic acid) is a lipophilic beta-hydroxy acid that provides gentle, controlled exfoliation by acting at the skin surface and within follicles. It is used to improve skin texture, unclog pores, and address acne and signs of photoaging while being generally well tolerated.
