For personalized advice and to ensure compatibility with your skin type, consult a dermatologist before introducing new products into your routine.

Best BHA/PHA Exfoliants: Frequently Asked Questions

What are BHA’s in skin care?

BHA stands for beta hydroxy acid, most commonly salicylic acid. It’s an oil-soluble exfoliant that penetrates deep into pores to remove excess sebum, dead skin cells, and buildup. BHAs are especially helpful for oily and acne-prone skin.

What are PHA’s in skin care?

PHA stands for polyhydroxy acid. PHAs are chemical exfoliants with larger molecules than AHAs and BHAs, which makes them gentler on skin. They exfoliate the surface, improve texture, and hydrate at the same time—making them a great option for sensitive or dry skin types.

Which BHA exfoliant is best?

The best BHA exfoliant depends on your skin type and concern. Toners and serums with salicylic acid work well for blackheads and clogged pores, while BHA cleansers can help with daily oil control. Look for formulas with soothing or hydrating ingredients to balance the exfoliation.

What do BHA’s do for your skin?

BHA’s exfoliate deep within the pores, helping to reduce blackheads, whiteheads, and acne. They also improve skin texture, minimize the appearance of pores, and promote a clearer, smoother complexion.

Can you use a BHA exfoliant/toner daily?

Some people can tolerate daily use, but it depends on your skin’s sensitivity. Beginners should start with 2–3 times per week and increase frequency if skin adjusts well. Always follow with sunscreen during the day, as exfoliation can make skin more sun-sensitive.

How often should I use a BHA exfoliant/toner?

Most skin types benefit from using a BHA exfoliant 2–4 times per week. Oily or acne-prone skin may be able to handle more frequent use, while sensitive skin may need less.

Who should avoid BHA’s & PHA’s?

It is always best to consult with a dermatologist for personalized recommendations before trying a new skin care product. Generally, people with extremely sensitive skin, eczema, rosacea, or those allergic to salicylates should be cautious with BHAs. PHAs are gentler and often better tolerated, but anyone with highly reactive skin should patch test first.

Which BHA toner is best?

The best BHA toner is one that matches your skin type. For oily or acne-prone skin, choose a lightweight formula with salicylic acid. For combination skin, look for a toner that balances exfoliation with hydrating ingredients like glycerin or hyaluronic acid.

Some best-selling options available at Ulta Beauty include:

• COSRX AHA/BHA Clarifying Treatment Toner – A gentle toner that exfoliates and refines skin texture while keeping it hydrated.
• FARMACY Deep Sweep 2% BHA Pore Cleaning Toner – A fan-favorite for clearing pores and controlling excess oil without over-drying.
• ANUA BHA 2% Gentle Exfoliating Toner – A mild exfoliating toner perfect for sensitive skin, helping to smooth and clarify.

What does a BHA toner do?

A BHA toner exfoliates after cleansing to remove dead skin cells, unclog pores, and prepare skin for serums and moisturizers. It helps minimize breakouts, reduce oiliness, and refine skin texture.

Can I use a BHA cleanser daily?

Yes, most BHA cleansers are formulated for daily use, especially for oily and blemish-prone skin. However, if your skin becomes dry or irritated, scale back to every other day and balance with a gentle, hydrating cleanser.

What is a BHA cleanser?

A BHA cleanser is a face wash that contains beta hydroxy acids, usually salicylic acid. It gently exfoliates while cleansing, helping to clear pores and reduce excess oil without the stronger intensity of a leave-on treatment.
