Who was studied
20 patients with acne vulgaris
Sample size

Measured outcome
In a prospective, randomized, evaluator-blind, split-face trial of 20 patients with acne vulgaris, two 50% glycolic acid + 0.5% salicylic acid peels significantly reduced total lesion count (P<0.001) and produced fewer side effects than Jessner's solution.
Certainty
Moderate
Who was measured
Patients with acne vulgaris receiving two 50% glycolic acid + 0.5% salicylic acid peels 2 weeks apart (one side vs Jessner's solution on the other).
Study limits
Small sample (20) and a combination peel (glycolic + salicylic acid); this is a procedural peel.

  1. Skin effect
    The effect of physically applied alpha hydroxyl acids on the skin pore and comedone

    In 23 women, a single application of a 4% alpha-hydroxy acid solution combined with negative-pressure physical action significantly reduced whitehead and blackhead counts at 1, 2 and 4 weeks, and reduced pore area and number at week 1, compared with AHA peeling alone.

    Shake-Induced Temporary Ion-Pairing Between Lecithin and Glycolic Acid for Enhanced Exfoliation in a Novel Biphasic Serum: Comparative Ex Vivo and in Vivo Randomised Studies

    In a 2-week double-blind split-face study of 37 participants, a biphasic serum with 10% glycolic acid delivered 45.52% greater exfoliation (p<0.001) and improved skin brightness, texture and hydration versus the comparison side.

  3. Skin effect
    A comparative study of gluconolactone versus benzoyl peroxide in the treatment of acne

    In a double-blind trial of 150 people with mild-to-moderate acne, a 14% gluconolactone solution and a 5% benzoyl peroxide lotion each reduced inflamed and non-inflamed lesion counts significantly more than the vehicle lotion, and fewer side-effects were reported with gluconolactone than with benzoyl peroxide.

  4. Skin effect
    Topical azelaic acid, salicylic acid, nicotinamide, sulphur, zinc and fruit acid (alpha-hydroxy acid) for acne

    Against topical tretinoin, salicylic acid showed similar values in overall acne improvement (RR 1.00, 95% CI 0.92 to 1.09; one trial, 46 participants). The review graded the certainty of that finding as low.

    Guidelines of care for the management of acne vulgaris (2024)
