How long does it take for topical clindamycin to calm inflamed acne (nodularcystic)? (tretinoin at night, no usage of oral antibiotics)

Thanks for the detailed summary. There’s no problem at all with seeing a GP to treat your acne – the treatment algorithm for acne is pretty standard. My pet peeve is only with clinics who overcharge based on having some sort of special super secret ingredient “miracle acne creams”, because the reality is that all effective topical creams contain well-known ingredients, and packaging it under their own brand shouldn’t give them the right to charge more, or “lock-in” patients to only using their creams.

Hi S – Unfortunately apart from Benzoyl Peroxide, the rest of the topical creams require a prescription in Singapore. The National Skin Centre pharmacy is your best bet (and probably cheapest option) for all the creams above, including Epiduo, Retinoic cream and Clindamycin. Otherwise, private dermatologists/aesthetic doctors and GPs with a special interest in skin will likely stock some or all the above creams, in that order of likelihood.
