Aspirin contains acetylsalicylic acid, a salicylic-acid derivative. Salicylic acid is a very useful ingredient in combating acne, and it can also lighten pigmentation over time. If you have those issues, why not try this treatment once a week?
Heat up a few teaspoons of water. Add two whole aspirin tablets to the water, mash with a spoon and mix thoroughly. Massage the mixture onto the skin and leave it on for about 5 minutes. Repeated use of this treatment will lighten and brighten the skin over time.
