Yes it is safe. If this is the first time you have used an acid treatment, we recommend that you first do a test on a small part of the face, and gradually introduce the Peeling ampoule into your routine.
The Peeling ampoules help to exfoliate our face in an effective, complete and uniform way, being suitable for the daily routine. Therefore, our advice would be to stop using other products that you use for facial exfoliation, whether they are physical or with AHA or BHA acids.
Our vials always come in an amber glass vial that guarantees the preservation of the formula from UV rays, light and oxidation. Once the ampoule is opened, the recommendation for use is to apply it morning and/or night, keeping it open for a maximum of 48 hours to guarantee its effectiveness.
