Welcome to HealthcareMagic,
yes dear its is side effect of the ACUTRET
(10MG) which you are taking for acne
.It a common side effect which occurs usually after 2 wks of the therapy.But this side effect goes off once you stop the medicine.Usually it is given for approx 6 months depending upon your body wt.It is good and very effective medicine.There are other precautions which needs to be taken while one is on acutret..some investigations need to be done...Kindly talk to your dermatologist
about these precautions.You can apply CETAPHIL
MOISTURIZING CREAM on lips as and when required or any lip balm to keep it moist.
