Hi,
From the photo, it appears that you have mild acne with comedones (whitehead & blackheads) and a few inflamed small lesions (or papules as they are termed medically). Do refer to the Acne section for more details on the various treatment options for mild acne.
A combination of topical benzoyl peroxide and topical retinoid (tretinoin or adapalene) will probably a good first line treatment option to start with.
Do see your doctor for a closer examination, full assessment and discussion of treatment options. It is important to treat mild acne early before it gets more severe and cause scarring.
Hope this helps!
