Botanical ingredients reduce mild acne-related erythema
A pilot study recently published in the Journal of Drugs in Dermatology shows that a combination of salicylic acid and botanical extracts can reduce erythema associated with mild acne.
Researchers combined an over-the-counter topical gel containing 2 percent salicylic acid combined with botanicals that have been known to have anti-inflammatory properties.
This was a proof-of-concept randomized, blinded, split-face study whose goal was to determine if this formulation could reduce the redness, elevation and induration associated with acne lesions. It included 25 patients who, after 10 days, reported having a 15-20 percent reduction in redness consistently over the course of the study.
