Shah often recommends over-the-counter retinols or prescription retinoids to her acne-prone patients. “I find that compared to other treatments they are beneficial for not just treating acne but also preventing new acne from forming as they help prevent that initial stage of the follicle getting clogged,” she says. “They can also help with some of the post acne [problems] such as hyperpigmentation.” But keep in mind if you have sensitive skin (or eczema or rosacea), a prescription retinoid might be too strong an option. However, your dermatologist can recommend an over-the-counter retinol with a low concentration (0.1 to 0.25 percent), which might be better tolerated. Retinol also isn’t a quick fix. It takes time to see results, and it’s something you’ll have to keep using to maintain its benefits. Shah also mentions that retinol plays well with other acne treatments on the list. "Retinol can be combined with other over-the-counter or prescription medications such as benzoyl peroxide, topical antibiotics, and oral medications. The right combination depends on the severity of the acne and your skin type."
Benzoyl peroxide (BPO) is a first-line treatment for mild and moderate acne due to its effectiveness and mild side-effects (mainly skin irritation). In the skin follicle, benzoyl peroxide kills C. acnes by oxidizing its proteins through the formation of oxygen free radicals and benzoic acid. These free radicals are thought to interfere with the bacterium's metabolism and ability to make proteins. Additionally, benzoyl peroxide is mildly effective at breaking down comedones and inhibiting inflammation. Benzoyl peroxide may be paired with a topical antibiotic or retinoid such as benzoyl peroxide/clindamycin and benzoyl peroxide/adapalene, respectively.
Oral isotretinoin is very effective. But because of its potential side effects, doctors need to closely monitor anyone they treat with this drug. Potential side effects include ulcerative colitis, an increased risk of depression and suicide, and severe birth defects. In fact, isotretinoin carries such serious risk of side effects that all people receiving isotretinoin must participate in a Food and Drug Administration-approved risk management program.
Hydroquinone lightens the skin when applied topically by inhibiting tyrosinase, the enzyme responsible for converting the amino acid tyrosine to the skin pigment melanin, and is used to treat acne-associated postinflammatory hyperpigmentation. By interfering with new production of melanin in the epidermis, hydroquinone leads to less hyperpigmentation as darkened skin cells are naturally shed over time. Improvement in skin hyperpigmentation is typically seen within six months when used twice daily. Hydroquinone is ineffective for hyperpigmentation affecting deeper layers of skin such as the dermis. The use of a sunscreen with SPF 15 or higher in the morning with reapplication every two hours is recommended when using hydroquinone. Its application only to affected areas lowers the risk of lightening the color of normal skin but can lead to a temporary ring of lightened skin around the hyperpigmented area. Hydroquinone is generally well-tolerated; side effects are typically mild (e.g., skin irritation) and occur with use of a higher than the recommended 4% concentration. Most preparations contain the preservative sodium metabisulfite, which has been linked to rare cases of allergic reactions including anaphylaxis and severe asthma exacerbations in susceptible people. In extremely rare cases, repeated improper topical application of high-dose hydroquinone has been associated with an accumulation of homogentisic acid in connective tissues, a condition known as exogenous ochronosis.
Therefore, it is very important that you wear sunscreen everyday, with an SPF of 30.Of note, after SPF 30, there are decreasing marginal returns in UVB protection. The % of UVB protection as a function of SPF Value is a log graph and plateaus after SPF 30. Therefore, there is not much difference in protection between SPF 40 and 50. Sunscreens with an SPF 100 are banned in some countries.
Baby acne is a common condition that affects many babies within several weeks to several months of age. Most pediatricians agree that the best treatment for baby acne is nothing at all, since the condition is natural and will clear up quickly enough as long as the baby's face is gently washed. Under severe conditions, though, your baby's doctor may recommend a stronger treatment. Here's what you need to know about getting rid of baby acne.
The Pore Normalizing Cleanser is designed just to cleanse, not treat, which is a good thing: The Nurse Practitioner study emphasizes the importance of washing with mild cleansers in conjunction with topical acne medications to combat or avoid excessive skin irritation. This one is water-based and fragrance-free, and uses sodium laureth sulfate (as opposed to its harsh cousin sodium lauryl sulfate) to eliminate any chance for irritation.
Isotretinoin is an oral retinoid that is very effective for severe nodular acne, and moderate acne that is stubborn to other treatments. One to two months use is typically adequate to see improvement. Acne often resolves completely or is much milder after a 4–6 month course of oral isotretinoin. After a single course, about 80% of people report an improvement, with more than 50% reporting complete remission. About 20% of patients require a second course. Concerns have emerged that isotretinoin use is linked with an increased risk of adverse effects, like depression, suicidality, anemia, although there is no clear evidence to support some of these claims. Isotretinoin is superior to antibiotics or placebo in reducing acne lesions. The frequency of adverse events was about twice as high with isotretinoin, although these were mostly dryness-related events. No increased risk of suicide or depression was conclusively found. Isotretinoin use in women of childbearing age is regulated due to its known harmful effects in pregnancy. For such a woman to be considered a candidate for isotretinoin, she must have a confirmed negative pregnancy test and use an effective form of birth control. In 2008, the United States started the iPLEDGE program to prevent isotretinoin use during pregnancy. iPledge requires the woman under consideration for isotretinoin therapy to have two negative pregnancy tests and mandates the use of two types of birth control for at least one month before therapy begins and one month after therapy is complete. The effectiveness of the iPledge program has been questioned due to continued instances of contraception nonadherence.
Antiandrogens such as cyproterone acetate and spironolactone have been used successfully to treat acne, especially in women with signs of excessive androgen production such as increased hairiness or skin production of sebum, or baldness. Spironolactone is an effective treatment for acne in adult women, but unlike combined birth control pills, is not approved by the United States Food and Drug Administration for this purpose. The medication is primarily used as an aldosterone antagonist and is thought to be a useful acne treatment due to its ability to additionally block the androgen receptor at higher doses. Alone or in combination with a birth control pill, spironolactone has shown a 33 to 85% reduction in acne lesions in women. The effectiveness of spironolactone for acne appears to be dose-dependent. High-dose cyproterone acetate alone has been found to decrease symptoms of acne in women by 75 to 90% within 3 months. It is usually combined with an estrogen to avoid menstrual irregularities and estrogen deficiency. The medication has also been found to be effective in the treatment of acne in males, with one study finding that a high dosage reduced inflammatory acne lesions by 73%. However, the side effects of cyproterone acetate in males, such as gynecomastia, sexual dysfunction, and decreased bone mineral density, make its use for acne in this sex impractical in most cases. Hormonal therapies should not be used to treat acne during pregnancy or lactation as they have been associated with birth disorders such as hypospadias, and feminization of the male babies. In addition, women who are sexually active and who can or may become pregnant should use an effective method of contraception to prevent pregnancy while taking an antiandrogen. Antiandrogens are often combined with birth control pills for this reason, which can result in additive efficacy.
Acne treatment that you apply to the skin: Most acne treatments are applied to the skin. Your dermatologist may call this topical treatment. There are many topical acne treatments. Some topicals help kill the bacteria. Others work on reducing the oil. The topical medicine may contain a retinoid, prescription-strength benzoyl peroxide, antibiotic, or even salicylic acid. Your dermatologist will determine what you need.
