If you are using any acne cream or facewash let it go on the way. But strictly you wash your face with ice cold water 3 times daily, From the second day you get the result

• Change your pillowcase daily. If you're poor just buy a bunch of cheap white towels from Walmart. If you're lazy just rest your head on clean shirts. Also if you flip it over you can get a couple uses out of it.
• Dyes and perfumes irritate many peoples skins. Choose a detergent without these chemicals when doing the wash.
• Don't use a fabric softener. Can be irritating.
• Avoid dairy. This one actually cured my acne. I didn't eat much cheese but when I stopped my face completely cleared up. If you search PubMedyou will see a lot of studies showing a link between dairy and acne. Again, with some people there is no correlation at all. It depends on your genetics.
• The other dietary link to acne for some people is food high on the glycemic index. The glycemic index measures how quickly blood sugar levels rise after eating some food. Basically, try a paleo diet and cutting out sweets.
• Try to use lukewarm water. Very hot and very cold water irritates and dries out the skin. Contrary to popular belief, pore size is genetically determined and steam does not "open pores."
• While I'm on the subject, acne is interesting because it is one of those things in life that you have to kill with kindness. Harsh scrubbing will just exacerbate your acne further. It's a good metaphor for problem solving.
• Don't overwash your skin. For most people washing their face twice a day works best. With others once a day is actually better. However, rarely is it the case that washing his or her face more than three times a day gives better results.
• Prefer chemical exfoliation over manual. AHA's like Glycolic Acid and Lactic Acid and BHA's like Salicylic Acid are generally considered superior to physical exfoliation products because they don't irritate the skin (kill acne with kindness). A lot of people prefer BHA's for their anti-inflammatory properties.
• Prefer low concentrations of chemicals. Benzoyl Peroxide (BP) kills Propionibacterium acnes, the acne bacterium. If that is the sole cause of your acne it won't be much longer with BP treatments. That doesn't mean you should get a 10% BP product though. Studies have shown that 2.5% is just as effective without drying and irritating the skin as much. Also, don't apply it too often because you can get chemical burns. That happened to me a couple years ago when I was still a novice to acne research. Healed completely thankfully.
• Is acne only at one spot on your face? Only your shoulders or forehead, for example? Then the cause is likely something that touches those parts of your body, like greasy sheets or bangs. Try washing both with a detergent more often.
• Drink a lot of water. I'm sure you've heard this before in many different contexts. It's human fuel. 3 days without and you're done. Drink more water. How do you know if you're drinking enough? Your pee should be clear instead of yellow.
• Have a healthy diet. Acne is mostly caused internally and shows itself externally. You're probably deficient in Vitamin D and Omega 3 fatty acids, even with a good diet. Vitamin D is pretty much only obtained through direct sunlight and sunscreen/cloudy days/winter time prevents it from being synthesized. Also, the sun is bad because it causes skin cancer. Wear suncreen, hats, and take Vitamin D supplementation for optimal health. You can pretty much only get sufficient Omega 3's from a fishy diet and expensive grass-fed meats so I just supplement it instead. I only supplement Vitamin D and Fish Oil because even with an okay diet you're probably only deficient in those two things.
• If you move around a lot during sleep and your face is rubbing against a harsh fabric or oils it could irritate your skin. Try sleeping on your back with proper pillow positioning to maintain a neutral spine. Personally I have a bad back so I have to sleep on my side and just try not to move around too much.
• Don't touch your face. Your hands, and fingers especially, are probably dirty, or at least oily and greasy. The only time you touch your face is while you're washing your face and are cleansing/exfoliating/moisturizing/whatevering.
• Don't pick at your skin or squeeze parts of your skin. The only time you should really do this is after you've washed your hands during your skincare routine and should only attempt it if it's ready to pop and you only need to apply a small amount of pressure in order to release it.
• Don't use any product that clogs your pores.Here's a list of comedeogenic ratings for products. Comedeogenic just means tendency to clog pores. This list doesn't mean that something with a 4 will definitely clog your pores though (depends on skin type/genetics/etc). Some people are fine with coconut oil, for example. I just chose to skip that step and just go with products rated a 0 like Shea Butter.
• Use a moisturizer if your skin is dry. How do you know if your skin is dry? Well, hours after your skin care regimen or after you wake up, is your skin dehydrated at all? Do you have any crusted skin near your eye area or does your skin feel really tight and not elastic? You may also only need to moisturize certain areas (combination skin). See how your skin normally feels without it and react accordingly.
• Cleanse your skin during your skin care routine. During the day and night bacteria accumulates, skin cells turnover, sebum is produced, oils are gathered, and products (make-up, sunscreen, moisturizer, etc.) are applied. It's just like brushing your teeth. Twice a day and feel fresh.
• Exfoliate, but not too often. It can lead to redness but also allows you to remove the outer layer of skin to reveal the newer skin beneath. Maybe a couple times a week. Chemical is great but physical can be good too, every once in a while. Try Extra Virgin Olive Oil and White Sugar rubbed on your skin a couple times a month, for example. Works great for the rest of your body too.
• Avoid the sun. Other than sunlight basically being carcinogenic by UVA and UVB radiation mutating DNA and causing skin cancers and premature aging but its "positive" effect on acne is mostly an illusion. After getting a tan acne may be less visible but that's just because your skin was damaged and is darker so it's harder to see. The reason why I said mostly is because sometimes sunlight can legitimately help acne by killing acne-causing bacteria with UV rays. Can be a decent short-term solution though.
• Use a moisturizer if you're going to be hit by harsh winds. Also, use a sunscreen if you're going outside (UVA rays penetrate clouds and are present all-year round).
• I generally like to avoid expensive products. Most of acne is caused by something already mentioned and most fixes are free and those that aren't can be purchased cheaply. Shea butter, oils, vaseline, sugar, gentle cleansers, and other basic skin care products are cheap. Even if something expensive does work, do you really want to depend on that forever? Don't be swindled in to the artificial markup. All the ingredients used in most formulations are cheap and massively produced. Other than for cleansing, I like to use single ingredients for skin-care.
• If you don't feel like researching ingredients, look for labels that indicated gentleness. Prefer descriptions like non-comedogenic, gentle, fragance-free, and paraben-free. Just note that these aren't really regulated and the effectiveness of a product is based on its ingredients and their proportions.
• Almost forgot to mention hormones. Changes and fluctuations with hormones can affect your acne. Women on their period, beginning menopause, pregnancy or changing birth control can all have an effect on your skin. I never spent much time researching this because I'm male but my best advice is to be scientific. If you changed your hormonal birth control and acne appeared shortly after and you haven't had it in years then it's pretty obvious what happened. Experiment with different types of birth control if this happens.
• Avoid stress. It sound weird but stress can cause acne and other conditions. Acne can be mainly hormonal and stress can effect your androgen and cortisol levels which can lead to sebum production, for example. Try meditating, avoiding stressful situations, avoiding negatives emotions, and stay relaxed.
• When in the shower, wash your face last, or at least after washing your hair. If you cleanse your face and then shampoo, oils and debris from your hair is washed off and drips down all over your face and the rest of your body. Generally, I like to do a top-down approach when showering to avoid this issue, however minor it may be.
• Avoid large amounts of makeup and the use of many different products. A lot of women cover up their bad skin with makeup and in turn just make their skin worse with all the products clogging their pores. It's a vicious cycle. You'd be surprised how well a good moisturizer and proper skin care can replace blush, foundation, and other prettifying products.
• Visit /r/wicked_edge if you believe your acne to be partially caused by improper shaving techniques. Basically, use a sharp blade on warm, wet skin with a good lather and shave with the grain to avoid skin irritation. Also you save money in the long-term with cheaper blades. Be sure to use an unscented shaving soap that is non-irritating.
• Use one towel for drying your hair and one towel for drying your body. Keep them separated so you can keep the oils separated as well.
• Pat your skin dry instead of vigorously rubbing it dry. After your shower wipe all the dripping water off of you with your palms so not as much will be absorbed in to your towel so they stay cleaner for longer.
• Exercise daily but try to do it at a time before when you normally shower. For example, if you shower in the morning, exercise before-hand and shower right after. Exercise increases blood flow and nourishes skin cells and helps flush out cellular debris.
• Accutane, even with its myriad of potential side effects, is the best cure for acne available right now. It works by decreasing the size and output of sebaceous glands. It also makes sloughed off cells less sticky. It can cause dryness of the skin, lips, mouth, etc. It can also cause liver problems, depression, birth defects if taken during pregnancy, etc. Talk to a professional if nothing else works.
• If you've tried everything and even bit the bullet and tried Accutane for its entire course and still nothing you still have an option. Waiting. A lot of acne is hormonal and will eventually clear up on its own, eventually.
