1) STOP popping the spots, also known as pimples and zits. This may make the pimple look worse due to inflammation and irritation. Popping a zit can spread infection under the skin and produce even more pimples than before. If you do pop a spot then immediately clean it with soap and water or rubbing alcohol in order to prevent infection.
2) Remove any make-up you have on. Wearing make-up can clog pores, making them dirty and causing pimples.
3) Use a mild soap for sensitive skin but it doesn’t matter exactly what type of soap you use. It can be designed for acne-prone skin or not, but you will want to treat your skin gently. Harsh antibacterial soap may actually make your acne worse by irritating skin.
4) Remove dead skin cells regularly by exfoliating. Use a gentle scrub with natural defoliants like ground walnut shells, or use an over-the-counter chemical defoliant like salicylic acid or glycolic acid. Adding ground walnut shell to a thick moisturizer like cocoa butter can be effective too.
5) Use a good toner. Spray onto face or wipe on with a cotton ball and wipe off with a clean, dry cotton ball. This gets rid of excess cleanser and tightens pores. Good, inexpensive choices include plain witch hazel for normal to dry skin, lemon juice, or 3% hydrogen peroxide for oily skin.
6) Bacteria in pores is one cause of spots. Reduce the amount of bacteria by using toners containing anti-bacterial agents like alcohol, peroxide and benzalkonium chloride, and by using creams that contain benzoyl peroxide, which kill bacteria as well as cause the skin to regenerate faster.
7) Maintain a routine. Most acne treatments take time to work. It usually takes between two and eight weeks before you see any significant improvement, so you are going to have to be patient. Once you’ve gotten your acne cleared up, it’s important to continue with the treatment that’s working so it does not return.
8) Understand that if all else fails, contact a doctor. Mild antibiotics that are available only by prescription can help reduce acne. Keep in mind though, that the widespread overuse (taking antibiotics when you really don’t need them or for something they don’t treat) and misuse (not taking medication for the specified amount of time) of antibiotics has led to the development of multiple antibiotic resistant bacteria.
9) Keep hair off of your face if at all possible. If you want to keep your bangs, then consider taking showers regularly or keeping your forehead clean with oil-dabbing cloths / clean tissues / etc.
10) Get some good sleep. Stress increases your skin’s oiliness, which, combined with sweat and dirt, can clog pores and cause pimples. (Change your pillowcase frequently.)
