Your Guide to DIY Acidic Beauty Remedies

Don't let those roof rats eat all the citrus or throw away that near-expired milk, beauty buff. Those are valuable acids that can be used to make your face shine. These naturally acidic home remedies can brighten, tighten, smooth -- and they're probably already in your kitchen or backyard. Here are some common ingredients from strong to gentle that can concoct the perfect at-home peel.

Acetic Acid: This is commonly found in vinegar and is more acidic (about five percent) than many over-the-counter cosmetic products. The high acidity level makes skin inhospitable to blemish-causing bacteria. It also can help in the fading of surface scars and reducing redness due to acne.

Apple Cider Vinegar: Create a toner type of peel with one part ACV to four parts water. Rub it on your face for one to three minutes. Wash it off, pat skin dry, and follow with a moisturizer. Those with sensitive skin should be careful; this stuff is strong.
