From your description, your “bumpy” skin do seem to be what we frequently call: closed comedones. These are formed when there is an accumulation of debris, sebum and skin cells beneath the skin.
Treatment include:
- Retinoic creams, Benzoyl peroxide
- Exfoliation with chemical peels
- Oral medication to decrease sebum production such as oral contraceptive pills, Isotretinoin etc
As my colleague has pointed out, if it is not severe, the side effects of Isotretinoin may outweigh its’ benefits.
Intense lasers (such as fractional lasers) should not be performed concurrently when on Isotretinoin as it can impair healing and may cause further scarring.
Speak with your doctor so that an appropriate plan can be penned out for you.
Hope that helps.
All the best!
