Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got post inflammatory
hyperpigmentation leading to scars and also redness seems to be due to inflammation of skin..
As she has open pores it leads to more accumulation of dirt and leading to clogging of pores and black heads..
I would suggest that she should
consult a Dermatologist and get evaluated and a thorough clinical evaluation can help..
He can advise you to wash your face with
salicylic acid containing facewash..
Apply creams or ointments containing Kojic acid,
glycolic acid and arbutin..
You can also be advised Vitamin E and C preparations..
Exfoliate your skin twice a skin with a mild scrub to unclog pores and it will help in reducing blackheads..
Limit sun exposure and always apply a sunscreen lotion when exposed to sun..
Drink plenty of water, take nutritious diet and avoid oily food..
You can also go for treatments like
Microdermabrasion and chemical peeling..
Hope this information helps..
Thanks and regards.
