If you’re considering freshening yourself for summer, now’s the time to review your skincare options. An exfoliating peel is the most effective method, so select an at-home treatment or seek the services of a reputable salon. Unsure what to ask for? Here’s a breakdown of the key active ingredients (hydroxy acids) available. Glycolic acid: derived from sugar cane. It’s perfect for targeting aged or sun damaged skin, and is the most commonly used alpha-hydroxy acid. It can be irritating however, so begin with a less concentrated preparation. Citric acid: derived from citrus fruits. It has astringent and anti-oxidant properties. Lactic acid: derived from milk. It has similar properties to Glycolic acid but far gentler. And, Salicylic acid: a beta-hydroxy acid. It’s particular good for congested skin types as it penetrates deeply, targeting the root of the problem.
