Is this normal or is it an allergy?

Recommended Posts


I'm in the UK and stumbled across this website when i was desparately looking for help.

I managed to source some BP 2.5 from an online UK pharmacy and have used it for two nights in a row. The first time it semeed ok, no major itching or redness. This morning one side of my face has swelled and i have itchy red spots on my cheeks and chin. I only applied the BP to my chin where the spots are.

I feel a bit gross and am reluctant to keep using it in case it gets worse.

I'm not sure if it's an allergy or if this reaction is normal. I know by reading the instructions that i should expect redness and some irritation.

I tried to make an appointment at my doctors but they are closed for staff training, i was wondering if anyone had any advice on here?

Thank you.

From the FAQs:

Q: My skin looks absolutely terrible. It is peeling off, red, and I am miserable. What do I do?

A: You are either allergic to benzoyl peroxide, or you started too fast. 1-3% of people are allergic to benzoyl peroxide and experience swelling and/or crusting. If your skin swells up, discontinue use immediately. Most likely if you are experiencing severe dryness/redness, you simply started too fast. It takes a few days to a few weeks for your skin to become acquainted with benzoyl peroxide, and the redness/dryness should subside with time. Using a non-overdrying liquid cleanser can help preven this dryness as well. If you really can't stand the dryness, stop the Regimen completely, give your skin a few days to recover, and begin again with a much smaller dosage, only ramping up the dosage as you feel comfortable. But remember, you eventually need to use A LOT of benzoyl peroxide to achieve total clearing.
