Why salicylic acid is bad

Salicylic acid works by dissolving this cement that holds those sticky cells together in the clogged pores," explains Dr. Not only does salicylic acid fight against acne, it soothes the skin.

This ingredient is unique because it's very effective at fighting acne, but it has a soothing, calming effect on skin. The anti-inflammatory properties of this ingredient are not surprising, given its close chemical relationship to one of the most well-known anti-inflammatory drugs available, acetylsalicylic acid also known as aspirin!

When this occurs, something called salicylate toxicity can occur. That being said, the concentrations of salicylic acid found in over-the-counter products designed to treat blemishes and the dark marks they leave behind are too low to cause trouble. Some over-the-counter wart treatments, on the other hand, have much higher concentrations of salicylic acid, so you wouldn't want to spread those all over your body!

Levels of salicylic acid found in products designed to clear your complexion are usually very well tolerated. They almost never cause irritation or peeling when used once or twice a day. The acid fights existing blemishes and prevents future breakouts, while the soy extracts naturally brighten the skin. No matter what product you choose, it's important to look for products that also contain antioxidants, anti-inflammatories and hydrators to help protect the skin's barrier function and improve the overall health of your skin.

The chemical exfoliant and beta-hydroxy acid is a staple acne-fighting ingredient that experts recommend all the time to help clear pores. But it's not your best bet if you're over the age of Despite the drying factor, however, it really depends on your skin type. According to board-certified dermatologist Mona Gohara, MD, oily skin types of any age can benefit from salicylic acid.

But if your skin is super sensitive, it's probably best for you to skip it. Salicylic acid works best for blackheads and whiteheads. When used regularly, this ingredient may also prevent future comedones from forming. According to the American Academy of Pediatrics , benzoyl peroxide is the most effective acne-fighting ingredient available without a prescription. It works best on traditional red, pus-filled pimples pustules. In addition to removing excess oil and dead skin cells, benzoyl peroxide helps kill acne-causing bacteria beneath the skin.

Although the side effects of each ingredient vary, both products are considered safe overall. Salicylic acid should not be used by someone allergic to aspirin. Both ingredients may cause dryness and irritation when you first start using them.

Allergic reactions are rare , but they are possible. You should seek emergency medical attention if you develop extreme swelling or have trouble breathing. Salicylic acid dries out excess oils sebum in your pores.

However, it could remove too much oil, making your face unusually dry. Benzoyl peroxide may not be safe for sensitive skin. This ingredient may also stain your hair and clothes, so apply with caution and wash your hands thoroughly after use.

You should never use a salicylic acid- or benzoyl peroxide-based product for every step of your skin care routine. It may also increase your risk of skin cancer and scarring. It's a little complicated, but the exact structure of salicylic acid is important in explaining why and how it works so well. When it comes to skin-care products, there are two classes of acids you'll see often: beta hydroxy acids BHAs and alpha hydroxy acids AHAs.

Furthermore, salicylic acid is actually derived from willow bark, says cosmetic chemist Ron Robinson, and it belongs to a class of ingredients called salicylates. Are you still with us?

Good, because this is where it gets fun. Examples of AHAs, for reference, include glycolic and lactic acids. In other words, oil-soluble ingredients can penetrate the skin at a deeper level than their water-soluble counterparts. Robinson sums up their differences succinctly. What all of this means is that salicylic acid can get deep into your skin to do its job.

This quality is precisely what makes salicylic acid such a potent ingredient for targeting acne — especially for blackheads and whiteheads.
