What Is Salicylic Acid and How Does It Work?

Salicylic Acid

Salicylic acid is a natural hormone produced by plants as a resistance mechanism to pathogenic or environmental stress. It can be derived from willow bushes and trees, so you might have seen the term “willow bark extract” in labels of some cosmetic products.

There are two classes of acids usually incorporated in skin care products – alpha hydroxyl acids (AHAs) and beta hydroxyl acid (BHAs). AHAs are water-soluble acids from fruits that help peel away the skin’s surface to promote more evenly pigmented skin cells to take over. Some examples of AHAs include glycolic and lactic acids.

Skin is noticeably smoother to the touch after use of products with AHA. BHAs on the other hand are oil-soluble acids which can go deeper into pores to effectively remove dead skin cells and excess sebum.

Both acids are effective for deep exfoliation and neither type is better than another. They both can decrease inflammation and the appearance of large pores, even out skin tone, remove dead skin cells, unclog pores and improve overall skin tone. It’s just a matter of what your skin issues are and what you need to address them.

Salicylic acid is a specific type of BHA, which makes it perfect for use against acne and sun damage. Being an oil-soluble acid, it is more effective in going deeper into your pores and unclogging the impurities.

A potent dose of salicylic acid in your skin care product dissolves skin debris that can clog pores and acts as an anti-inflammatory agent to smooth out red inflamed pimples and pustules.

The below video goes into good detail on the specifics of salicylic acid:

Who Should Use It and How Often?

Salicylic acid is recommended for people prone to breakouts. Combination and oily skin types usually benefit the most but it can also be used in moderation by people with other skin types.

Experts suggest applying salicylic acid twice a day but frequency will still vary from product to product. Make sure to read the label fully and check with your dermatologist before starting a skin care regimen with salicylic acid.

Usage of salicylic acid is typically recommended once in the morning and once at night, especially when treating a serious case of breakouts. But care must be taken when using salicylic acid in the mornings as it can also make the skin sensitive to the sun.

If you already have sun-sensitive skin, you can either limit your usage of salicylic acid in the evening or just follow up your morning routine with plenty of sunscreen to protect your skin against UV rays.

How Is It Used or Applied?

There are many uses for salicylic acid which also corresponds to a few different methods of application. It is paramount to any skin care routine that any product be applied correctly or else it will not work as effectively.

In the case of salicylic acid, when using it in creams or ointments, enough portion must be applied gently on the affected area to ensure proper coverage and absorption.

The same application is done when salicylic acid is in gel form except the affected area must be treated with a wet pack at least five minutes prior to application of the salicylic acid gel. Pad versions of this product must be wiped on and left to dry on the affected portion of the skin.

Salicylic acid may also be incorporated in shampoos and soaps. If used as a shampoo, make sure your scalp is wet enough with lukewarm water before application of the product for 2-3 minutes. As a soap, hot water must be used and a thick lather with a washcloth is most effective. Make sure to rinse off all the product to avoid any residue.

A good moisturizer that includes salicylic acid and is at a great price is StriVectin Advanced Retinol Day Moisturizer SPF 30. It can keep your skin hydrated and the salicylic acid helps decrease acne ad other inflammation.

Benefits

The benefits of salicylic acid are as follows:

1. Acne treatment – first and foremost, salicylic acid is best used for treating acne due to it being oil soluble. BHA penetrates better into pores dissolving impurities and removes dead skin cells from the outermost skin layer. New studies have also found that cleansers with salicylic acid significantly reduce acne abrasions.

2. Treats hyperpigmentation – BHA has been found to have lightening capabilities which are suitable for both dark and light skin tones. Studies have also found that salicylic acid peels were an effective treatment for melisma and post-inflammatory hyperpigmentation.

3. Stimulates the production of collagen – salicylic acid promotes healthier production of collagen which helps in keeping our skin less saggy, plumper and with lesser wrinkles and fine lines. Regular use will also help in brightening the complexion by reducing the thickness of dead skin cells, giving a for a more radiant look.

4. Reduces pore size – the ability of salicylic acid to exfoliate the skin deeply helps in unclogging large pores that result from excess oil and debris. Pores will get the chance to reduce in size once the build-up of oils and dirt have been taken away by salicylic acid.

Side Effects

Obviously, you cannot have too much of a good thing. Use of salicylic acid in high doses can make your skin susceptible to irritation and redness. It must be noted, however, that the percentage of salicylic acid in products available in the market without prescription is tolerated very well by most people.

And salicylic acid is most commonly used as just a small portion of a larger formula. There are other ingredients that are incorporated into a skincare product that must be taken into consideration.

BHAs can also cause dry skin and can be quite irritating if used incorrectly. What’s worse, already damaged skin tends to absorb salicylic acid even quicker which aggravates any existing irritation.

Researchers have said that BHAs have an underlying pH-related potential to irritate the skin which is only intensified on sensitive skin type.
