FOR AHA SKIN PEELS INCLUDING GLYCOLIC ACID, LACTIC ACID AND COMBINATION PEELS
-
Do not use if pregnant, breastfeeding, allergic to aspirin, on photosensitising medications (e.g. Roaccutane), or undergoing strong skin treatments such as Retin-A, laser, or dermabrasion. Avoid use on broken skin, wounds, or if you suffer from cold sores.
-
No — these products are not suitable during pregnancy or breastfeeding.
-
No — wait at least one week after the cold sore has fully healed.

Yes, chemical peels can be safe for darker skin tones when performed by a qualified professional using the right type of peel. Superficial peels (like glycolic and lactic acid) are usually preferred, as they carry less risk of post-inflammatory hyperpigmentation. Stronger peels should be approached with caution and always under professional supervision.
-
Darker skin types are more prone to hyperpigmentation (dark marks) or, less commonly, hypopigmentation (light patches) after a peel if it’s too strong or not applied correctly. Choosing the right peel type, building tolerance, proper aftercare, and sun protection are key to minimising risks.
-
Yes, but you must take a cautious approach. Sensitive skin is more reactive, so the safest option is to start with a lactic acid peel at the lowest strength (10%). Lactic acid is gentler because it penetrates the skin more slowly.
-
Perform a patch test 48 hours before your first peel. If tolerated, begin with lactic acid at a very short application time (1–2 minutes), then neutralise. If your skin responds well, you can gradually increase the duration over several weeks.
-
Not initially. Glycolic acid penetrates deeper and is more stimulating, which can overwhelm sensitive skin. Once you have safely built tolerance with lactic acid — and your skin feels strong, stable, and calm — you may consider introducing a low-strength glycolic peel under cautious use.
