# I had a reaction after using Perfecting Solution N°03

It's important to note that slight redness may be normal immediately after the application of a peel containing active ingredients such as AHAs and PHAs (Alpha Hydroxy Acid and Poly Hydroxy Acid). Slight tingling may also be felt following use, as the skin is thoroughly cleansed. Peels are designed to remove dead skin cells and stimulate cell renewal, which may cause slight temporary irritation.

We strongly advise you to use our day/night cream or serum afterwards, and not to apply it more than once or twice a week. If you have sensitive skin, do not apply [Serum N°08](https://www.codageparis.com/products/serum-n08-night-rejuvenation) on the day you use it, to avoid sensitizing your skin.

For [Perfecting Solution N°03](https://www.codageparis.com/products/perfecting-solution-n-03), please read the precautions for use on the packaging and bottle.
