Whether you’re new to chemical exfoliants or looking to maximize your routine, we’ll share expert tips, highlight potential side effects, and empower you with everything you need to glow with confidence.
What is The Ordinary AHA BHA Serum?
The Ordinary is known for its affordable, science-driven approach to skincare. The brand’s focus is on transparency, offering powerful formulas without the luxury markup. The ordinary aha bha serum stands out as a cult classic, thanks to its blend of exfoliating acids that deliver visible results for many skin types.
This serum combines chemical exfoliants—AHA (Alpha Hydroxy Acid) and BHA (Beta Hydroxy Acid)—to target multiple skin concerns. AHAs, like glycolic and lactic acids, gently lift away dead skin cells from the surface, while BHA (salicylic acid) penetrates pores to dissolve excess oil and debris.
Here’s a quick look at the formula:
| Ingredient | Percentage | Function |
|---|---|---|
| Glycolic Acid (AHA) | 30% | Surface exfoliation |
| Lactic Acid (AHA) | Included | Gentle exfoliation, hydration |
| Salicylic Acid (BHA) | 2% | Deep pore cleansing |
| Tasmanian Pepperberry | - | Redness reduction, soothing |
| Hyaluronic Acid | - | Hydration, skin comfort |
The ordinary aha bha serum is designed to unclog pores, smooth texture, fade blemishes, and promote healthy cell turnover. Compared to other exfoliating serums, it offers high-strength acids at a budget-friendly price.
In 2026, the serum has seen minor packaging updates for sustainability, while the formula remains trusted by skincare enthusiasts. It’s best suited for oily, combination, and blemish-prone skin, but not recommended for sensitive types. For more expert insights and tips, check out this Expert Guide to The Ordinary Peeling Serum.
How AHA and BHA Work: The Science Explained
Ever wondered how the ordinary aha bha serum delivers such impressive results? The answer lies in the chemistry of its key ingredients. AHAs, or Alpha Hydroxy Acids, gently break the bonds that hold dead skin cells together, helping them shed from the surface. This process unveils a smoother, more radiant complexion. In contrast, BHAs, like salicylic acid, are oil-soluble and travel deep into pores, dissolving excess sebum and clearing out debris that can lead to breakouts.
Both acids have been backed by research for their effectiveness in treating acne, refining skin texture, and boosting radiance. For a deeper dive into how AHAs work on the skin, check out this resource on the mechanisms of action of AHAs in dermatology.
Why combine both? AHAs target surface dullness, while BHAs address clogged pores. This dual action makes the ordinary aha bha serum especially effective for those battling uneven tone and blemishes. The serum’s optimized pH ensures acids are active yet gentle, minimizing irritation.
Dermatologists often recommend patch testing before use, as chemical exfoliants can cause tingling or redness, especially on sensitive skin. Most users notice visible smoothness and clarity within a few weeks, making acid exfoliation a science-backed choice for glowing skin.

How to Use The Ordinary AHA BHA Serum Safely and Effectively
Embarking on your journey with the ordinary aha bha serum can be transformative when you follow a thoughtful process. Taking the right steps ensures you get the glowing benefits while minimizing the risk of irritation or discomfort.
Step-by-Step Application Guide
To get the most from the ordinary aha bha serum, start by cleansing your face thoroughly and patting it dry. Only apply the serum in the evening, limiting use to once or twice a week.
Dispense a small amount and spread it in a thin, even layer over your face, steering clear of the eye and lip areas. Set a timer for no more than 10 minutes, then rinse off completely with lukewarm water.
After rinsing, follow up with a gentle hydrating serum and a nourishing moisturizer to replenish your skin’s barrier. Keeping to this routine helps you experience smoother, brighter skin with minimal risk.
Important Precautions and Tips
Before your first use of the ordinary aha bha serum, always perform a patch test to check for any adverse reactions. Never combine this serum with other strong actives, such as retinol or vitamin C, on the same day.
Daily sunscreen is non-negotiable, as exfoliating acids increase your skin’s sensitivity to UV rays. If your skin is sensitive, broken, or compromised, avoid using this product. Expect a mild tingling or slight redness, which is normal, but discontinue use if irritation persists.
