<s>[INST] hi am 20yrs old.. I have a dark skin surrounding my mouth, that is the area below the nose and lower cheeks and chin........ i was using HYDE cream before 2yrs.... when i was using it,my mouth area was looking fair...and now i discontinued it and it again turned dark after discontinuing it. can i use it again surrounding my mouth... can you please suggest me any other good cream for me to lighten my mouth surrounding area....?? [/INST] HIThank for asking to HCMI really appreciate your concern looking to the history given here I could say that certain systemic condition might be responsible for this and in my opinion this need to be ruled out and for that you have to see the physician instead of using some skin lighting agent, hope this information helps you take care and have nice day. </s>
