Salicylic acid

 

Acne in many cases of mild to moderate severity are well suited to effective treatments such as Salicylic Acid, a form of BHA's (beta hydroxy acids). This agent is used for treatment of mild to severe comedonal acne (non-inflammatory lesions). Salicylic acid is also helpful as a renewing agent for scar treatment. These treatments are convenient to use, safe and effective. Four clinical studies support efficacy and safety of Salicylic Acid in concentrations less than 3% and renders them among effective acne treatments. Adverse reactions to Salicylic Acid are generally limited to slight irritations occurring in a minority of treated patients. Severity of acne is always a determinant factor for its treatment. Use of salicylic acid for treatment of non-inflammatory lesions is indicated, alone or in combination with other modalities.

A study on effective acne treatments done by Davis DA and et al attests that adult acne patients without gross skin disorders are at minimal risk of adverse systemic effects from routine use of topical products containing 2% Salicylic Acid, most popular form of BHA's.

Many studies support efficacy of Salicylic Acid in adult acne treatment and acne scars treatment, it reduces the number of microcomedones and counteracts plugging of the follicles. It is also effective in healthy women who take oral contraceptive without any adverse effect.

In three placebo-controlled studies and a comedolytic assay, salicylic acid pads reduced the number of primary acne lesions and thereby the number and severity of all lesions associated with adult acne. Comparative studies of salicylic acid have shown it to be superior such effective acne treatments as benzoyl peroxide. Adverse reactions to salicylic acid are generally limited to mild, local irritation occurring in a minority of patients.

Beta hydroxy acids are another group of cell turnover accelerators which are derivative of aspirin and naturally can be found in willow bark. The most well-known BHA is salicylic acid. Some authors claim that BHA's are stronger exfoliants than AHA's, alpha hydroxy acids, and interestingly more gentle to the skin. A salicylic cream is also facial pores-clearing and can help with both treatment of blackheads and comedone clearance. Use of BHA's alone for treatment of scarring is not very promising, even though overall somewhat smoother skin is the net result of using a salicylic acid cream for at least three months.
