Isotretinoin
Isotretinoin is a type of vitamin A derivative, a drug used especially for treating severe acne. It is often prescribed when conventional treatments are not effective, and because it is effective but also has many side effects, it is called the ultimate weapon (last resort) against acne.
It is a powerful drug that puts a burden on the liver, and taking it during pregnancy or while trying to conceive can cause teratogenicity (birth defects) in the fetus, so if you take it, an examination by a doctor and a blood test at a medical institution, including our clinic, are always required.
While it is very effective, its side effects are significant, so it cannot be the first choice for acne treatment.
If other treatments show no effect, it is prescribed at the doctor’s discretion.
At our clinic, we have you visit the acne clinic, carry out an examination and blood test, and prescribe it while carefully observing your condition.
Effects
- Suppression of sebum secretion: It shrinks the sebaceous glands and greatly reduces sebum secretion, suppressing clogged pores and the growth of acne bacteria
- Normalization of the stratum corneum: It prevents the keratin of the skin from hardening and reduces clogged pores
- Anti-inflammatory action: It has the effect of reducing inflammation caused by acne
- Prevention of recurrence: The effect continues long after treatment ends and can prevent acne from recurring
Side effects
While isotretinoin is highly effective, many side effects may occur
- Dryness: Dryness of the skin, lips, eyes, and nose is the most common
- Cracked lips: Along with dryness, lips often crack
- Effects on liver function: It may burden the liver, so liver function must be checked during treatment
- Teratogenicity: Taking it during pregnancy has serious effects on the fetus, so pregnancy during treatment must absolutely be avoided. Contraception is strongly recommended for female patients during the treatment period
