Synopsis

Rating (out of 5): 3

Apple acid, more commonly known as malic acid, is an alpha-hydroxy acid (AHA) naturally present in apples and other fruits. Its use in supporting or treating age spots (also known as liver spots or solar lentigines) is primarily based on its scientifically recognized exfoliating properties. AHAs, including malic acid, are widely used in dermatology and cosmetic products to promote skin cell turnover and improve pigmentation irregularities. Scientific studies have demonstrated that AHAs can reduce the appearance of hyperpigmentation, including age spots, by increasing epidermal cell turnover and facilitating the removal of pigmented, damaged skin layers.

Malic acid is less studied than glycolic or lactic acid, but research supports its effectiveness as an exfoliant and in improving skin texture and pigmentation. For example, a 2013 review in the Journal of Clinical and Aesthetic Dermatology concluded that AHAs can effectively lighten hyperpigmented lesions and improve photoaged skin. Topical malic acid is included in some over-the-counter formulations for these purposes. However, the evidence is less robust than for other, more potent AHAs, and most studies group AHAs together rather than focusing on malic acid specifically.

In summary, the use of "apple acid" (malic acid) for age spots is scientifically supported, mainly due to its AHA properties, although direct evidence for malic acid itself is less extensive than for other AHAs.
