As per your description, it will cystic acne which might be caused due to hormonal changes that usually happen during adolescent years. We recommend trying any above mentioned method to reduce the inflammation, redness and other discomforts caused by cystic acne. Apart from that, we have also mentioned dietary changes he should consider for effective and faster results.
Any acne treatment is a weeks-long experiment that you’re conducting with your skin. Acne is slow to heal, and in some cases, it can get worse before it gets better (nearly every benzoyl peroxide product we looked at emphasized the likeliness of irritating acne further, and starting off with a lighter application). April W. Armstrong, a doctor at the University of California Davis Health System, recommends waiting at least one month before you deem a product ineffective.
If you notice that you’re breaking out right around your period every month, your acne might be linked to hormones. “A sensitivity to the hormones called androgens manifests in the form of cystic acne,” Dr. Linkner says. Androgens, namely testosterone, cause the skin to produce more sebum. More sebum equals more acne. Birth control, which has estrogen and progestin, helps keep hormones balanced and skin clear. Ortho Tri-Cyclen, Estrostep, and YAZ are all FDA-approved as acne treatments.
Spot treatments are designed to give problem pimples a mega-dose of concentrated benzoyl peroxide — in a couple of regimens, like the Proactiv Teen Kit, the spot treatment had nearly three times the benzoyl peroxide as its all-over treatment. The logic: If benzoyl peroxide can be irritating to the skin in high concentrations, limiting its intensity to just the pimple itself could save the rest of your healthy skin.
How to Handle It: Pair two of the best-known acne-fighting ingredients, salicylic acid and benzoyl peroxide, in the week leading up to your period. (If you're feeling bloated, now's the time to do it.) The combo can help prevent hormonal acne from happening in the first place. Zeichner suggests following a salicylic acid wash, like fan-favorite Neutrogena Oil-Free Acne Wash Pink Grapefruit Facial Cleanser ($7), with a benzoyl peroxide spot treatment, such as Murad Acne Spot Fast Fix ($22). If you're still seeing zits, "visit your dermatologist to discuss prescription options, like birth control pills, oral spironolactone — which blocks oil — or topical Aczone 7.5 percent gel," says Zeichner. "It's shown to be particularly effective in adult women without causing irritation." Oral contraceptives level out those hormone fluctuations, keeping your oil production normal and your skin clear.
Natural treatments are usually free of the side effects sometimes caused by prescription options. But they may not be as effective. Research on natural options is lacking, and at this time nothing has been proven to produce results. Talk with your doctor about potential risks and to ensure the treatment won’t interact with any medications you’re taking.
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). Topical antibiotics alone aren't recommended.
