Detailed Answer:
Hello, and welcome to 'Ask A Doctor'

Thanks for posting your query.

I have gone through your query.
For Acne you need:-
- Regular and gentle washing of your skin with a mild cleanser like Cetaphil twice daily.
- Avoid harsh cleanses.
- Avoid all the regular use creams, moisturisers, sunscreens that you may be using for the time being till you are on anti-acne treatment.
- Avoid taking facials.
- Avoid picking your acne.
You will need oral antibiotics if you are having red, pus filled acne. You can take:
- Capsule Doxycycline 100 mg once daily at bedtime for 2 weeks
- Apply gel containing combination of benzoyl peroxide and adapelene on the lesions at bedtime for 1 hour and gradually increase the contact time to 2 hours, 3 hours and then overnight.
- Topical antibiotics like either Clindamycin 1%/ benzoyl peroxide 2.5% OR Nadifloxacin creams should be applied during the day time.

For pores:-
Oral retinoids reduce the size and hence the activity of sebaceous glands to 10% of what it initially was, after a month of regular use. You can take:-
- Tab. Isotretinoin at a low dose of 10 mg or 5 mg once daily, for this purpose
- Regular salicylic acid chemical peeling will also refine your pore size. The peeling sessions are usually repeated once every 2 weeks.
For sun protection you may use a broad spectrum sunscreen e.g Neutrogena ultrasheer dry touch sunblock with SPF 50, can be used 15-20 minutes before stepping outdoors.

Most of them are prescription medicines and you may want to visit a dermatologist before starting the medicines.

I hope this helps. Please feel free to discuss further if any.
Regards,
