You should not wash the areas of the skin treated with benzoyl peroxide for at least 1 hour after application.
First, lather your face with a Benzoyl Peroxide wash. Let it sit for 5-10 minutes. Then rinse it off with water.
1 If you're just beginning with your benzoyl peroxide treatment, start using moisturizer now, even before you notice any uncomfortable dryness. You may be able to stave off the worst of it. If you've already succumbed to benzoyl peroxide-induced dryness and flakiness, slather on moisturizer as often as necessary.
Benzoyl peroxide, like all treatments, takes time to work. You may need to wait eight to 10 weeks, sometimes a bit more before seeing a noticeable improvement in your skin. As tempting as it may be, don't slather on more medication, or apply more often than directed.
When using topical benzoyl peroxide, moisturize first. Let in soak in, then apply the benzoyl peroxide. This helps buffer the medication and compensates for its drying effects. With benzoyl peroxide cleansers or washes, first cleanse, then apply moisturizer while your skin is still damp.
Leaving a wash on overnight may irritate the skin due to the detergents in the wash. There are however benzoyl peroxide products that can be used as a wash, short-contact therapy (meaning you leave it on for 10-15 minutes then wash off) or as a leave-on product.
You've probably seen these emergency pimple treatments at the drugstore — usually an extra-strong solution of salicylic acid, glycolic acid, or benzoyl peroxide. And yep, they can actually get rid of pimples overnight.
If you're new to benzoyl peroxide, start with once a day only. Gradually work your way up to morning and night applications. If you use a retinoid or retinol product at night, apply benzoyl peroxide only in the mornings. This will prevent irritation and other side effects.
If you use a product containing benzoyl peroxide, it is best to wait until this product has been fully absorbed before applying a serum and/or moisturiser. Benzoyl peroxide works best when it has the chance to absorb into the skin first. This only takes a few seconds.
Don't leave wash-off benzoyl peroxide products on your skin, as this can increase the chances of irritation and dryness. Since all benzoyl peroxide products – especially at higher concentrations – can have a drying effect on the skin, it's a good idea to use a non-oily moisturizer after each use.
During the first 3 weeks you are using benzoyl peroxide, your skin may become irritated. Also, your acne may seem to get worse before it gets better. If your skin problem has not improved within 4 to 6 weeks, check with your doctor.
It can even remove dark spots and pimples or acne scars. The key difference between any benzoyl peroxide product and other topical antibiotics for acne like clindamycin is that our bodies do not build up an antibiotic resistance to the product.
People can find benzoyl peroxide in over-the-counter (OTC) topical treatments or in lower concentrations in supermarket products, such as face and body washes. Benzoyl peroxide also has bleaching qualities.
Use An Over-the-Counter Acne Spot Treatment
Salicylic acid, mentioned above, is one of these. Another important ingredient to look for is benzoyl peroxide. In addition to reducing oil and removing dead skin cells, benzoyl peroxide also helps kill the bacteria that cause the pimples.
Does putting toothpaste on a pimple make it go away? You may have heard this suggestion, but experts on acne say don't try it. Toothpaste could make that spot on your skin even more red, irritated, and noticeable.
If you have blackheads and whiteheads, salicylic acid alone should work well to clear out your pores. If your acne tends to be inflammatory, such as papules and pustules, opt for benzoyl peroxide to stop outbreaks at the source. For sensitive skin, start with salicylic acid, since it's less likely to cause irritation.
To help with the dryness and flaking, apply the moisturizer before the acne medication. If you're using a benzoyl peroxide cleanser, apply the moisturizer immediately after washing your face while the skin is still damp.
Benzoyl Peroxide and Premature Skin Aging:
Benzoyl peroxide creates free radicals and is known to cause premature skin aging, just like repeated sun exposure or persistent acne.
Benzoyl peroxide does not usually darken your skin. Some brown or purplish spots may appear in the acne-affected areas, which are completely normal and part of the healing process. But in rare cases, benzoyl peroxide can cause hyperpigmentation and dark skin.
Dark spots
But constantly touching the zit can leave behind a stubborn dark spot or scar that can take weeks if not months to fade. But benzoyl peroxide can help you get rid of the dark spot quicker. It has the ability to slough off dead skin cells, making dark spots and scars appear less prominent.
Benzoyl peroxide is not classifiable as to its carcinogenicity to humans (Group 3).
Your skin is very smart; it regulates itself and produces only as much sebum as it needs to stay healthy, hydrated, and youthful. However, when we wash it too much, it first becomes overly dry. This leads to a backup of dead skin, and in turn triggers an overproduction of sebum.
