Oily skin is caused by the production excess sebum, which can lead to clogged pores, trapped bacteria and ultimately acne.  And while acne is often thought of as a teen malady, it can strike adults too, and at any age. When evaluating skin care products, pay close attention to the active ingredients. Here are four super ingredients that will help kill bacteria, promote cell turnover and keep your skin looking radiant– not shiny.

Tea Tree Oil is a natural antiseptic, made from the leaves of a tree that is native to the land down under:  Australia. This essential oil is extremely helpful for correcting many skin and hair conditions, and is especially helpful in maintaining the appropriate balance for the treatment of oily skin because it dissolves skin oils and kills bacteria that can cause acne.

Salicylic Acid is a type of Beta Hydroxy Acid (BHA) that treats oily skin by opening up clogged pores and neutralizing bacteria. This ingredient comes from bark of a willow tree, and is known for helping to break down blackheads and whiteheads by stripping off the outer layer of skin.

Glycolic Acid is an Alpha Hydroxy Acid (AHA) that is used in many products for oily skin– in particular, peels that help improve the skin's texture and overall appearance. Glycolic Acid is derived from sugar cane.

Hyaluronic Acid  is used when treating oily skin, it's important to make sure you're not over-drying it, which can cause your glands to react by producing even more sebum. A natural way to boost your skin's moisture is with hyaluronic acid. This acid, which occurs naturally in our bodies, is actually the main ingredient in Restylane, a gel injected into the skin to reduce facial wrinkles and lines.  By the time we reach 50 years of age, our bodies are producing about 50 percent less hyaluronic acid than they did in youth.  This decline is a major contributing factor to... wrinkled, sagging skin.
