1. The ABC's of Alpha-Hydroxy Acids
Alpha-hydroxy acids (AHA's) are chemical compounds which are both naturally occurring and created in a laboratory. AHA's are thought to help reduce the look of fine lines and wrinkles and are found in small concentrations in a number of beauty creams and acne remedies and in larger amounts in chemical peels. While alpha-hydroxy acids are generally considered safe, products which contain more than a 20 percent concentration of AHA's must be applied by a licensed professional, as high concentrations may cause severe skin irritation such as flaking skin and redness.
2. Alpha vs. Beta
While many products claim that alpha-hydroxy acids help to fight acne, their counterpart, beta-hydroxy acid (BHA), is really much better at reducing outbreaks. AHA's are soluble in water while BHA is soluble in fat. Fat soluable beta-hydroxy acid penetrates into the skin, helping to exfoliate dead skin cells and clear sebum from pores to clear acne. The bottom line is that products which promote anti-aging properties should contain AHA's, while acne fighting products should contain BHA.
3. Erasing Wrinkles
Alpha-hydroxy acids are the main ingredient in chemical peels. Over-the-counter chemical peels contain less than 10 percent of AHA's. While they are still effective, they must be used regularly for long lasting results. Trained cosmetologists have access to products which contain 20 to 30 percent AHA's. These products are usually applied 1 to 3 times with results lasting from 3 to 6 months. Doctors on the other hand can use products which contain up to 70 percent AHA's, which offer results that can last up to 5 years.
4. Cleopatra's Beauty Secret
Lactic acid, found in dairy products, is one of the most common alpha-hydroxy acids, and was first recorded as being used by Cleopatra who smothered her skin in sour milk to keep a youthful look. Yogurt or powdered milk facials as well as milk baths are great home remedies for skin care. Additionally, AHA's such as citric acid found in lemons, grapefruit and oranges, malic acid which is found in apples and tartaric acid found in grapes can all be added to your home beauty recipes.
5. Fun in the Sun
It is common knowledge that excess sun exposure is the fastest way to age your skin. Unfortunately, the use of AHA's increases your sensitivity to the sun, making protection even more important. Wear sunscreen with a minimum 15 SPF every day, even on cloudy days and reapply when necessary.
