Rating (out of 5): 4

Vitamin A, particularly in the form of topical retinoids (such as tretinoin, retinol, and adapalene), is scientifically validated for the treatment and cosmetic improvement of age spots, also known as solar lentigines or liver spots. Retinoids are derivatives of vitamin A that have been extensively studied in dermatology for their effectiveness in promoting skin cell turnover and reducing hyperpigmentation associated with chronic sun exposure and aging.

Numerous clinical studies and dermatological guidelines support the use of topical retinoids for fading age spots. Retinoids work by accelerating the exfoliation of pigmented keratinocytes and stimulating the production of new, evenly pigmented skin cells. In addition, they inhibit the activity and transfer of melanin, the pigment responsible for dark spots, by modulating gene expression in skin cells. According to peer-reviewed studies published in journals such as the Journal of the American Academy of Dermatology and Dermatologic Surgery, regular use of tretinoin and other retinoids can result in significant lightening of age spots and improvement in overall skin texture and tone over several months.

While some mild irritation or dryness may occur, retinoids are considered a first-line, evidence-based option for non-invasive management of age spots. Oral vitamin A is not used for this purpose due to toxicity concerns. Overall, the use of vitamin A derivatives for age spots is strongly supported by scientific evidence and clinical practice.
