Hi! You could try using a gentle BHA exfoliant or BHA based serum/toner etc (from Cosrx or Some By Mi) to help with the bumps After that for additional maintenance in the long-run, the Houttuynia Cordata will help. Just on it's own, it would help but it might take longer as it is more gentle
Hello, we have had cases where our customers have used it while on oral isotretinoin. To be sure, you can check with your dermatologist, or patch test and mix it with a calming One Thing Extract - like Artemisia. Or even use a couple drops in a soothing moisturiser or toner to ensure that it is gentle on your skin.
