Glycolic acid provides many benefits to your skin. When it becomes a regular part of your skin care regimen, it can be effective increase the production of collagen (which is needed to have firmer and youthful-looking skin). It can also improve the skin's elasticity and thickness while at the same time diminish hyperpigmentation.

When you use glycolic acid as part of your skin care routine, expect a slight tingling or stinging sensation. However, this is just temporary and as you continue using glycolic acid in its recommended proportion and concentration, the sensation will altogether disappear. Your skin will also feel flaky and dry with the use of glycolic acid, but most skin care preparations add other ingredients to minimize dryness and flaking. Glycolic acid can be used in combination with salicylic acid, vitamins and colostrum to further improve its skin renewing and rejuvenating powers and counteract glycolic acid's "negative" effects.

Aside from these benefits, glycolic acid is useful in treating acne and its resulting scars, blackheads and whiteheads, psoriasis, eczema, sun damage, seborrheic keratosis and even pre-cancerous growths.

When using glycolic acid, start with fewer applications until the skin is able to adjust to its effects. Then you can increase the number of applications over time. When you overdo the application, your face may turn red and the sting may last longer. You may even notice a burning sensation on your face when you perspire. You should also expect some break outs on your skin, as it is in the process of adjusting with the treatment.

Care should also be used when applying it around the eye area. Since the skin in this region is thinner, the acid may make the eye area look crinkled or dry. When this happens, stop applying glycolic acid to the eye area even as you use it on the other parts of your face. This area will eventually "catch up" with the others so that you can use the product evenly and your face will peel at a uniform and even rate.

When your skin is extremely sensitive or when you have a cut, open sores or abrasions, it is best to avoid applying glycolic acid. As this may do more harm than good.

Now, this article is not written to discourage your use of glycolic acid. It is very useful for renewing the skin, but you should use it with your dermatologist's advice to ensure its maximum effectiveness and avoid any skin damage. There may be some inconveniences you have to put up with but when you see how your skin has improved you will readily agree that it is well worth the sacrifice.
