After a cosmetic treatment, we can advise you on a skincare regimen to follow. Many cosmetic treatments, such as chemical peels and medical needling [microneedling] stimulate new collagen production through controlled trauma to the skin. It is therefore normal for the skin to become more sensitive after treatment. All post-treatment skincare, such as moisturisers or cleansers, focus on restoring the natural protective barrier of the skin. By ‘nursing’ the skin back to health and encouraging the skin to heal will allow results to be that much better.

However, after a heavy-duty treatment or undergoing plastic surgery of any type is not the time to start experimenting with new products. Plus, there are plenty of ingredients that you'll want to steer clear of until your doctor gives you the green light (usually one week or so depending on the procedure and how the skin is healing) to resume using them. Those actives include:

Retinol & Retinoids: For as much good as retinol and retinoids do, the one time you want to stay away from the vitamin A derivatives at all costs is after anything invasive. Some providers advocate for using retinol to help speed up the exfoliation process post-treatment, but this needs to be done carefully and under strict supervision.
Anti-Acne Ingredients: Those who regularly use anti-acne ingredients like salicylic acid and benzoyl peroxide should not use them (or any other blemish fighters) until the skin fully heals because acids and other potent actives can further compromise and dry out the skin.
Vitamin C: Some skin types are inherently sensitized by vitamin C, depending on the concentration and source, which is why many experts suggest laying off of it in the days following a procedure.
