What is beta hydroxy acid?
Beta hydroxy acids (BHAs) are chemical compounds that act as deep exfoliators. While betahydroxy acid ingredients may be listed as topical acids, beta hydroxybutanoic acid, ortrethocanic acid, and salicylic acid are generally the only BHAs used in skincare products. Originally extracted from the white willow tree bark, BHA is now synthetically made and commonly used for both at-home and professional skin rejuvenating and acne treatments.
What are the benefits of beta hydroxy acid?
Beta hydroxy acid is oil-soluble, allowing it to penetrate deep into pores, removing sebum anddead skin cells. BHA acts as an exfoliant and helps to reduce the appearance of fine lines, darkspots, and other tell-tale signs of photo-aging. Beta hydroxy acid boosts cellular turnover, whichimproves skin texture, blotchy pigmentation, and skin tone. People with oily or acne-prone skincan benefit from it, as it regulates sebum production, reduces large pores, and preventscomedones from forming.
BHA helps with these skin types
Dry Skin
BHA is made up of molecules that love water, and it helps improve the skin's moisture content. However it isn't suitable for extremely dry skin.
Normal Skin
BHA is a great exfoliant for normal skin and exfoliates the skin's surface while helping it hold onto more moisture.
Helps with these environmental & lifestyle factors
Helps counter the effect of high stress on your skin. Living with too much stress ramps up your body's production of cortisol—and wreaks havoc on your skin.
Helps fight the effects of pollution on your skin. Polluted air contains small nanoparticles which cause premature aging. Clinical studies show that people with low pollution exposure levels have brighter, healthier, more radiant looking skin.
Calibrated for every age
It refines the skin, making it smoother, creating a more even skin tone, a brighter appearance, and gives you radiant skin from within.
It is a perfect fit to address the primary skin care concerns for people in their 20s and early 30s. Make it a part of your regular skin care routine for healthy, beautiful skin.
This is a great time to make it a part of your skincare routine as you start thinking about incorporating more ingredients with anti-aging benefits.
It is a great bet for consistent, everyday incorporation in your skincare routine as it not only will tighten up your anti-aging regimen but also help you achieve firmer, more youthful skin.
As skin matures, it tends to lose hydration and feel dry. This helps hydrate and plump the skin, reducing the appearance of fine lines and wrinkles.
Usage guide
How to use beta hydroxy acid?
BHAs are gentle enough for daily use, but you may need to start sparingly-- two or three times a week-- until your skin gets acclimated. Because this active increases the skin’s sun sensitivity, it’s essential to use a broad-spectrum sunscreen.
When to use beta hydroxy acid?
If your skin is excessively oily, congested, and acne-prone, you will likely benefit from BHA. Don’t be alarmed if you experience mild redness and peeling after the first few applications, as this is normal and will subside.
What is beta hydroxy acid found in?
You’ll find BHA acid in toners, facial cleansers, moisturizers, exfoliating pads, pore-refining serums, peels, and masks. To combat breakouts, look for concentrations of at least 2 percent salicylic acid.
Is beta hydroxy acid suitable for sensitive skin?
Those with sensitive skin should consult their dermatologist before incorporating any BHA into their skincare regimen. It can be too irritating for rosacea-prone and reactive skin at higherstrengths-- look for products containing no more than 2 percent BHA.
Things to keep in mind
Beta hydroxy acid side effects
Beta hydroxy acid is less irritating than other acid exfoliants, owing to its larger molecule size and lipid solubility. Salicylic acid-- the only BHA used in skincare formulations -- has strong anti-inflammatory properties, but possible side effects can include redness, itching, burning, and irritation-- depending on the concentration level.
Ingredients to avoid with beta hydroxy acid
BHA will increase sensitivity to UV rays, as well as certain skincare ingredients. Until your skin is accustomed to this exfoliant, avoid using it in conjunction with topical retinoids—such as derivatives of Vitamin A, as this can cause excessive irritation.

Getting the most from beta hydroxy acid
How to use BHA to exfoliate, clear pores, and calm breakouts without overdoing it.
- Ease in slowly BHA is gentle enough for daily use, but start two or three times a week until your skin acclimates. Mild redness or peeling early on is normal and settles down.
- Always follow with sunscreen BHA increases your skin’s sun sensitivity. A broad-spectrum SPF every morning is essential while you use it.
- Let it reach into pores Because BHA is oil-soluble, it penetrates deep to clear sebum and dead cells. That makes it well suited to oily, congested, and acne-prone skin.
- Hold off pairing it with retinoids Until your skin is used to BHA, combining it with retinol can cause excess irritation. Alternate them on different nights instead of layering.
