Wear sunscreen everyday and do not tan. Ultraviolet Radiation is the number one cause of premature aging. It also leads to skin cancer in high enough doses. Treat the sun like the death ray that it is. Exposing your skin to harmful UVA and UVB rays damages skin and prolongs post inflammatory erythema(PIE)--red acne marks, as the sunlight stimulates pigment-producing cells.
The bad news: There's no secret ingredient or miracle gadget that makes scars totally disappear. Don't get discouraged, though. A lot of what you think is acne scarring is really just hyperpigmentation or erythema (brown or red spots) rather than an actual change in the texture of the skin. Plus, there's a bevy of gels, creams, and treatments that can bring that discoloration down. We asked top dermatologists to recommend the most effective of the bunch.
26. Get your SPF on. Sunscreen isn't just for summer—your skin needs protection every day, even in winter. There are now sunscreens for every skin type imaginable—even ones that help make your skin less oily, so your face stays matte and pimple-free! Look for a daily moisturizer with SPF that says it's "lightweight," "oil-free," or "oil-controlling." For the highest level, look for a PA++ rating, it covers both UVA and UVB rays, so you're guarded against everything from burns to future wrinkles!
Sunscreen: "Sun exposure during an active breakout can lead to darkening of inflammatory lesions, prolonging their appearance on your skin and making them harder to fade over time," says Dr. Shereene Idriss from Union Square Dermatology, which means it's important to lather on the sunscreen daily — even when it's cloudy. And don't worry about breaking out from a pore-clogging sunscreen; the latest formulas are more innovative and acne-friendly than ever. Elta MD UV Clear Broad-Spectrum SPF 46 is a top derm-approved favorite. It contains niacinamide, which is an anti-inflammatory that helps reduce redness.
Take a small fresh lemon and squeeze out its content juice. Apply the juice directly on the scars using the finger tips or a clean cotton ball, leave it for about 10 minutes and wash it off using cold water. Do this at least once a day for about two to three weeks during after which you can see the scars disappear considerably. If you want, you can also mix some honey with the lemon juice to make it some more effective in reducing of the acne scars.
Some skin advocates suggest foregoing this method. The pH of baking soda is 7.0, which is far too basic for skin's pH. Optimal skin pH occurs between 4.7 and 5.5, which is an inhospitable environment for p. acne (the bacteria responsible for causing most acne). By raising the pH to a more basic level, p. acne is able to survive longer and cause more infection and inflammation. So try this method with care, and stop using it if it's not effective for you.
Exfoliating cleansers and masks: A variety of mild scrubs, exfoliants, and masks can be used. These products may contain salicylic acid in a concentration that makes it a very mild peeling agent. These products remove the outer layer of the skin and thus open pores. Products containing glycolic or alpha hydroxy acids are also gentle skin exfoliants.
