What do they do?

AHAs work by dissolving the sticky substance between cells that stop the skin’s dead surface cells from falling off naturally. They also exfoliate the dry, damaged cells that clog pores and cause unsightly blemishes and infections.

So why would I benefit from using AHAs?

Some benefits of using AHAs are:

• they can exfoliate dead skin cells, giving you a clearer and cleaner complexion.
• They are great moisturisers (with 8% of either glycolic acid or lactic acid) - even better than normal moisturisers.
• Good for using on dry areas on the body as well - so throw away your tired old loofah. You can apply this type of body scrub just before putting on your fake tan for a more even and longer lasting result.
• Effective in reducing aging signs such as fine lines and discolouration.
• Good for acne.

How should I use this type of product?

If you are using Retin A or hydrocortisone cream for any reason - seek out the help of a beautician or other expert before using AHA creams.

Otherwise, most skincare specialists recommend that they be used only at night time after your skin has been thoroughly cleansed.
