Hi there.
Empathise with your problem. Since it is 12 years, prefer it if you could upload both frontal & lateral view clear photographs & using the 'upload data' feature, upload it onto this site. Understand from the sign-off name that you may be a woman & apprehensive..hence please feel free to ask for me specifically & use the special 'ask-a-doctor' package & WE CAN TAKE IT FURTHER FROM THERE.
As you have used many creams et al over the years, dont want to suggest yet another remedy haphazardly. Rosacea needs to be addressed in toto with advice on diet & DIET habits, photoprotection creams & advice, topical immunomodulators eg 1% pimecrolimus & yes systemic (oral) meds such as isotretinoin & psychological counselling pertaining to handling stressors. All this is a package deal & needs a detailed consult. If you get back & tell me which region of India or the world you reside, i would be happy to recommend a dermatologist in your area, Personally I am from Bangalore & you are most welcome to visit me here! Cheers & wish you good health & closure of the rosacea issue soon!

Hi,
Welcome to HealthCareMagic,
Following Life style changes will be helpful:-
Take nutritious & balanced fibre rich diet, sleep for 8 hours daily and drink more than 8 glasses of water a day. Never pick or squeeze pimples.
Acne treatment is focused on (1) to unclog pores, (2) to kill bacteria, and (3) to minimize oil.
Wash your face twice daily with a mild cleansing soap or liquid. It will keep your skin clean and minimize sensitivity and irritation or cleanse twice daily with a 5% benzoyl peroxide wash. An alternative for those who are allergic to benzoyl peroxide is 2% salicylic acid.
A variety of mild peeling agents (scrubs, exfoliants, and masks) can be used. These products remove the outer layer of the skin and thus open pores.
Retinol (derivative of vitamin A) can help promote skin peeling.
To get rid of oil on your face and reduce the embarrassing shine, use a gentle astringent/toner to wipe away oil. Masks containing sulfur and other ingredients draw out facial oil. Antibacterial pads containing benzoyl peroxide have the additional benefit of helping you wipe away oil.
Apply a gel or cream containing 5% benzoyl peroxide; an alternative is sulfur or resorcinol.
At night, apply a spot cream containing sulfur to the affected areas.
Use a light skin moisturizer and water-based oil-free makeup.
You may require a course of Antibiotics (erythromycin, clindamycin , sulfacetamide or azelaic acid).
Retinoids ( Retin-A /adapalene/tazarotene) are especially helpful for unclogging pores. Epiduo gel contains the adapalene along with the antibacterial cleanser benzoyl peroxide and can be applied once daily.
Some contraceptive pills have been to shown to have modest effectiveness in treating acne. Spironolactone act by blocking androgen (hormone) receptors.
Cortisone injections make large pimples and cysts flatten out fast.
Isotretinoin is an excellent treatment for severe, resistant acne. It should be used for people with severe acne, chiefly of the cystic variety, which has been unresponsive to conventional therapies like those listed above.
Laser treatments of acne is best thought of as an adjunct to conventional therapy, rather than as a substitute.
Superficial chemical peels (like glycolic acid) & deeper ones (performed in the doctor's office), are modest, and give supportive benefit only, and in general, they do not substitute for regular therapy.
Don't be afraid to hide blemishes with flesh-tinted coverups or even foundation, as long at it is water based (which makes it noncomedogenic). Steaming and "deep-cleaning" of pores is useful. Strips are available, which you can put on your nose, forehead, chin, etc., to "pull out" oil from your pores.

Hope you found my response to your query informative and helpful.
With good wishes,
Dr.Chandra Shekhar Sharma
