Crush up some aspirin. Crush up an aspirin tablet and add just enough water to make it into a paste. With a Q-Tip, add the aspirin paste to the pimple(s) lightly, covering entirely. Let dry. Aspirin is another anti-inflammatory, meaning it will help the skin fight against inflammation, making the pimple less visible. Let the aspirin paste fight the pimple overnight.
In dermatology, PDT with the photosensitizer Levulan Kerastick (20% delta-aminolevulinic acid HCl) is used for the treatment of very early, thin skin cancers called actinic keratoses (AK). The initial approval was specifically for the treatment of actinic keratosis of the face and scalp with a combination of an application of the photosensitizer followed by a timed exposure to a special blue light source. PDT is also used for acne, rosacea, skin cancer, sun damage, cosmetic skin improvement, oily skin, enlarged sebaceous glands, wrinkles, rejuvenation (anti-aging), warts, hidradenitis suppurativa, psoriasis, and many other skin conditions.

Tea tree oil, due to its anti-inflammatory effects would definitely help you in getting rid of such acne scars. This oil is also hydrating.

Moderation and regularity are good things, but not everyone can sleep eight hours, eat three healthy meals per day, and drink plenty of water a day. Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
