hi..thanks for your query.
the treatment for the scars depend on the nature and extent of the inflammatory injury.There can be either hyper pigmentation following acne ,or there may be atrophic scars as a result of deeper injury.
For hyperpigmented scars , the treatment options include:
1)Topical depigmenting creams: creams containing Hydroquinone, Kojic acid, arbutin etc.
2) Chemical peels : Glycolic peels for a few session from an experienced dermatologist ever 2-3 weeks.
Sunscreens should be applied on the face always to prevent these scars from getting darker.
For atrophic scars, treatment options include
1) Chemical peels: TCA peels
2) Microdermabrasion
3) Laser
4) Dermarollers
Usually a combination of 2-3 methods give an optimum result
Hope this helps.Take care!

Hello,
Thanks for the query

Retinoids are the drug of choice today for acne, comedones as well as acne scars.

you can apply 1 % adapelene gel once daily in night, a sunscreen must be applied in day.
usually there are not much side effects except slight burning.

It usually takes around a month for lesions to disappear with regular treatment.

However for best results apply the creams for at least 2 months even if there are no lesions.

Acne is blockade of sebaceous duct, do the following to keep them open.

1. Wash face at least three times a day. Instead of soap use a pH balanced syndet.

2. Drink lot of water and reduce oily food intake.

3. Take lot of green leafy vegetables, they add fiber which in turn reduce oil absorption from intestine.

4. Don’t apply too many cosmetics and don’t change them, use a single brand whichever suit you.

Thank you
