Yes, you can use a BHA in the morning and an AHA at night. BHA stands for beta hydroxy acid, and AHA stands for alpha hydroxy acid. Both are chemical exfoliants that can help improve skin tone and texture. Generally, BHA is better for oily skin, while AHA is better for dry and sensitive skin. However, using both can be beneficial for most skin types, as long as they are used in the right concentrations and at the right times.

Can I use AHA in the AM and BHA in the PM?

Yes, you can use AHA in the morning and BHA in the evening. AHA (alpha hydroxy acid) is a chemical exfoliant that helps to remove dead skin cells and reduce the appearance of wrinkles. BHA (beta hydroxy acid) is an oil-soluble exfoliant that helps to clear clogged pores and reduce inflammation. Both AHA and BHA can be used together to provide maximum benefits, however, you should always use a broad-spectrum sunscreen with an SPF of at least 30 when using these products.

Can you use BHAs twice a day?

Yes, BHAs (beta hydroxy acids) can generally be used twice a day — once in the morning and once in the evening. However, it is important to consult with a dermatologist before using any type of chemical exfoliant, since sensitive skin may be more prone to irritation. It is also important to use a sunscreen when using BHAs, since they can increase the skin’s sensitivity to the sun.
