My 13 yr old DD has benzoyl peroxide treatment for acne and is getting sore skin (it’s clearing the acne though). She needs moisturiser to help, oil free to stop it making her acne worse, but most moisturisers sting. Purifide 30spf works during the day but I’m after a cream for the night that doesn’t sting and doesn’t break the bank! I’m a bit rubbish at this stuff - not really sure which of the ingredients will be making her skin sting and so what to avoid. Any ideas?
