AHA & BHA Exfoliants Explained: How to Use The Ordinary's Peeling Solutions Safely

Exfoliating acids are some of the most effective — and most misused — products in skincare. The Ordinary's AHA and BHA formulas can dramatically improve texture, tone, and clarity, but only if you use them correctly. Here's what you need to know before adding one to your routine.

AHA vs BHA: What's the Difference?

AHAs (alpha hydroxy acids, like glycolic and lactic acid) are water-soluble and work on the skin's surface to improve texture, brighten dullness, and smooth the look of fine lines. BHAs (beta hydroxy acids, primarily salicylic acid) are oil-soluble, meaning they can get inside pores to clear out excess oil and debris, making them especially useful for blackheads and breakouts.

The Ordinary's AHA 30% + BHA 2% Peeling Solution

This is one of The Ordinary's most iconic products: a concentrated, at-home peeling treatment that combines both acid types in a single formula. Because of its strength, it's designed for occasional use only, not as a daily step, and is best suited to those who already have some experience with exfoliating acids.

How Often Should You Exfoliate?

For most people, 1 to 3 times per week is enough. Overusing exfoliating acids can damage the skin barrier, leading to redness, sensitivity, and even more breakouts — the opposite of what you're trying to achieve. Start with once a week and only increase frequency if your skin tolerates it well.

How to Use Exfoliating Acids Safely

• Always patch test a new acid before applying it to your full face.
• Apply to clean, dry skin, and follow the product's recommended contact time.
• Introduce one acid at a time; don't combine multiple strong exfoliants in the same routine.
• Follow up with a gentle, hydrating moisturizer to support your skin barrier.
• Always wear sunscreen the next day — exfoliated skin is more vulnerable to sun damage.

What Not to Mix With Exfoliating Acids

Avoid layering AHA/BHA exfoliants with retinoids, Vitamin C, or other strong actives in the same routine, as this increases the risk of irritation. A simple rule of thumb: use your exfoliating acid on its own at night, and keep the rest of that routine minimal — cleanser and moisturizer only.
