What is a type of superficial chemical peel?

1. Salicylic acid

2. TCA (trichloroacetic acid)

3. Retinoic acid

4. Phenol

The correct answer is: Retinoic acid

A superficial chemical peel primarily targets the outermost layer of the skin, also known as the epidermis. This type of peel is generally less invasive and has a shorter recovery time compared to deeper peels. Retinoic acid is recognized for its ability to enhance the turnover of skin cells and improve skin texture. It works by promoting exfoliation and is significantly effective in treating conditions like acne and hyperpigmentation. Retinoic acid can stimulate collagen production and facilitate cell renewal at a superficial level, making it a suitable choice for a superficial chemical peel. In contrast, the other options, including salicylic acid, TCA, and phenol, represent different types and depths of chemical peels. Salicylic acid is often used in superficial peels as well; however, it's more focused on treating specific issues like acne due to its oil-solubility. TCA and phenol are utilized for medium to deep chemical peels, targeting deeper layers of the skin, thus involving more extensive recovery periods and potential risks.
