Glow Definition
BHA in skincare refers to beta hydroxy acid, a type of oil-soluble exfoliant most commonly represented by salicylic acid. Unlike water-based exfoliants that target surface buildup, BHA can penetrate into pores, making it especially popular in routines that aim to clarify and smooth the skin.
Often found in toners, serums, and spot treatments, this ingredient is well-suited for oily or congestion-prone skin types, though it’s frequently included in multi-benefit exfoliating formulas as well.

Why It Matters
BHA in skincare plays a unique role in refining the skin’s surface while helping maintain clarity beneath it. Because it’s oil-soluble, it pairs especially well with routines built around decongestion, refining texture, or supporting a balanced glow.
When incorporated thoughtfully, BHA can be a foundational ingredient for those looking to streamline and simplify their exfoliation approach — especially in humid or breakout-prone seasons.
GLOW TIP Pair your BHA exfoliant with a gentle, fragrance-free cleanser to help maintain balance — especially in summer routines focused on skin clarity and glow.
Why We Love It For Glow
BHA brings glow where you least expect it — by diving deep into pores and helping clear buildup that can dull your skin’s natural light. While often associated with oily or blemish-prone skin, it’s also a favorite in glow routines for its ability to refine texture, smooth rough spots, and create the kind of surface that reflects light — no highlighter needed.
When used a few times a week in balanced lineup, BHA helps skin look more even, less congested, and ultimately more radiant.

FAQ
Can I use BHA every day?
It depends on your skin. Some routines include BHA two to three times a week, while others build up to daily use. If you’re just starting out, begin with fewer applications and see how your skin responds over time.
What’s the difference between AHA and BHA?
AHAs work on the skin’s surface and are water-soluble, while BHAs are oil-soluble and can reach into pores. BHA is often preferred for oily or congestion-prone skin, while AHA is used more for texture and tone refinement.
Can I use BHA with retinol?
You can, but it’s often best to alternate nights or layer thoughtfully to avoid over-exfoliation. If using both, apply BHA first, let it fully absorb, then follow with retinol and a barrier-supporting moisturizer.
