That’s why, no matter how uncomfortable your skin may feel while plagued with acne, you must resist the urge to touch your skin. If the irritating sensations become unbearable, there are other methods of treating your skin, such as cooling it with ice packs or aloe vera gel. You can even use medicated creams designed to soothe irritated skin – given that your dermatologist says it’s okay.
You won't find a face wash in this list that's not universally beloved, but keep in mind that what works for one person won't work for everyone. The biggest secret to finding a great facial cleanser is choosing one that's formulated for your skin type: dry, oily, combination, sensitive or blemished. Unfortunately, few women really know their skin type.

Oral antibiotics are recommended for no longer than three months as antibiotic courses exceeding this duration are associated with the development of antibiotic resistance and show no clear benefit over shorter courses.[87] Furthermore, if long-term oral antibiotics beyond three months are thought to be necessary, it is recommended that benzoyl peroxide and/or a retinoid be used at the same time to limit the risk of P. acnes developing antibiotic resistance.[87]

Azelaic acid has been shown to be effective for mild to moderate acne when applied topically at a 20% concentration.[66][129] Treatment twice daily for six months is necessary, and is as effective as topical benzoyl peroxide 5%, isotretinoin 0.05%, and erythromycin 2%.[130] Azelaic acid is thought to be an effective acne treatment due to its ability to reduce skin cell accumulation in the follicle, and its antibacterial and anti-inflammatory properties.[66] It has a slight skin-lightening effect due to its ability to inhibit melanin synthesis, and is therefore useful in treating of individuals with acne who are also affected by postinflammatory hyperpigmentation.[1] Azelaic acid may cause skin irritation but is otherwise very safe.[131] It is less effective and more expensive than retinoids.[1]
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.[34] By interfering with new production of melanin in the epidermis, hydroquinone leads to less hyperpigmentation as darkened skin cells are naturally shed over time.[34] 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.[34] The use of a sunscreen with SPF 15 or higher in the morning with reapplication every two hours is recommended when using hydroquinone.[34] 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.[34] 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.[34] 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.[34] 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.[34]

The dermatologist Dr. Dennis Gross did a major study on water and its effect on skin and he found that the heavy metals in tap water can actually ruin the benefits expensive lotions and serums do for skin. Some cities (New York and L.A., for example) have worse water than others (Seattle, for example). While some dermatologists aren't buying his claims, (Patricia Wexler for one), you can fight the drying effects of water on skin by cleansing with cold cream, a practice common with European women.
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
