Acne Spot in my Face

The most common topical prescription medications for acne are:
Retinoids. These come as creams, gels and lotions. Retinoid drugs are derived from vitamin A and include tretinoin (Avita, Retin-A, others), adapalene (Differin) and tazarotene (Tazorac, Avage). You apply this medication in the evening, beginning with three times a week, then daily as your skin becomes used to it. It works by preventing plugging of the hair follicles.
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin).
Dapsone (Aczone). This gel is most effective when combined with a topical retinoid. Skin side effects include redness and dryness.
Antibiotics. For moderate to severe acne, you may need oral antibiotics to reduce bacteria and fight inflammation. Choices for treating acne include tetracyclines, such as minocycline and doxycycline.
Your doctor likely will recommend tapering off these medications as soon as your symptoms begin to improve or as soon as it becomes clear the drugs aren't helping — usually, within three to four months. Tapering helps prevent antibiotic resistance by minimizing undue exposure to these medications over a long time.
You will likely use topical medications and oral antibiotics together. Studies have found that using topical benzoyl peroxide along with oral antibiotics may reduce the risk of developing antibiotic resistance.
Antibiotics may cause side effects, such as an upset stomach and dizziness. These drugs also increase your skin's sun sensitivity. They can cause discoloration of developing permanent teeth and reduced bone growth in children born to women who took tetracyclines while pregnant.
The most common side effects of these drugs are headache, breast tenderness, nausea, weight gain and breakthrough bleeding. A serious potential complication is a slightly increased risk of blood clots.
Anti-androgen agent. The drug spironolactone (Aldactone) may be considered for women and adolescent girls if oral antibiotics aren't helping. It works by blocking the effect of androgen hormones on the sebaceous glands. Possible side effects include breast tenderness, painful periods and the retention of potassium.
Isotretinoin. This medicine is reserved for people with the most severe acne. Isotretinoin (Amnesteem, Claravis, Sotret) is a powerful drug for people whose acne doesn't respond to other treatments.
Oral isotretinoin is very effective. But because of its potential side effects, doctors need to closely monitor anyone they treat with this drug. The most serious potential side effects include ulcerative colitis, an increased risk of depression and suicide.
These therapies may be suggested in select cases, either alone or in combination with medications.
Light therapy. A variety of light-based therapies have been tried with success. But further study is needed to determine the ideal method, light source and dose. Light therapy targets the bacteria that cause acne inflammation. Some types of light therapy are done in a doctor's office. Blue-light therapy can be done at home with a hand-held device.
Possible side effects of light therapy include pain, temporary redness and sensitivity to sunlight.
Chemical peel. This procedure uses repeated applications of a chemical solution, such as salicylic acid. It is most effective when combined with other acne treatments, except oral retinoids. Chemical peels aren't recommended for people taking oral retinoids because together these treatments can significantly irritate the skin.
Chemicals peels may cause temporary, severe redness, scaling and blistering, and long-term discoloration of the skin.
Extraction of whiteheads and blackheads. Your dermatologist uses special tools to gently remove whiteheads and blackheads (comedos) that haven't cleared up with topical medications. This technique may cause scarring.
Steroid injection. Nodular and cystic lesions can be treated by injecting a steroid drug directly into them. This improves their appearance without the need for extraction. The side effects of this technique include thinning of the skin, lighter skin and the appearance of small blood vessels on the treated area.
consult dermatologist for further evaluation and treatment.
