Is Kojic Acid AHA or BHA?

Is Kojic Acid an AHA or BHA? Let’s Settle This Once and For All

You’ve seen it on ingredient labels, hyped up in skincare blogs, and maybe even in that bottle sitting on your vanity right now. But if you’ve ever caught yourself asking, “Is kojic acid an AHA or a BHA?”—don’t worry, you’re not alone. This is one of the most common questions in the world of skincare, and today, we’re diving deep into the science behind it.

Let me channel my inner skincare guru and break it down for you. Spoiler alert: kojic acid is neither an AHA nor a BHA. But hold on—don’t let that discourage you. It’s still an MVP in the skincare game, and here’s why.

First, A Quick Refresher: What Are AHAs and BHAs?

Before we get to kojic acid, let’s take a moment to understand the basics of AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids).

AHAs are water-soluble acids, such as glycolic acid and lactic acid, that work on the surface of your skin. They’re amazing at exfoliating dead skin cells, brightening your complexion, and improving texture.

BHAs, like salicylic acid, are oil-soluble, which means they can penetrate deeper into your pores. They’re your go-to for battling acne and controlling excess oil.
Both are incredible, but kojic acid plays a different role altogether.

What Exactly Is Kojic Acid, Then?

Kojic acid is a naturally derived compound that comes from fungi during the fermentation of sake, soy sauce, and rice wine. Its superpower? Brightening skin and targeting hyperpigmentation.

Unlike AHAs and BHAs, kojic acid doesn’t exfoliate your skin. Instead, it inhibits tyrosinase, the enzyme responsible for melanin production. In simpler terms: it helps fade dark spots, even out your skin tone, and give you that glow-up we all crave.

Why Doesn’t Kojic Acid Fit the AHA or BHA Box?

The reason kojic acid doesn’t qualify as an AHA or BHA is because it doesn’t have the same structure or functionality. AHAs and BHAs are all about breaking bonds between dead skin cells or penetrating oil-filled pores. Kojic acid? It’s more of a skin-brightening ninja, quietly working behind the scenes to stop excess pigmentation in its tracks.

Think of it as the perfect sidekick to your AHAs or BHAs rather than a replacement. They exfoliate, kojic acid brightens—it’s a dynamic duo for glowing skin.

Where Does Kojic Acid Fit Into Your Routine?

Here’s the beauty of kojic acid: it’s versatile. You can find it in serums, creams, and masks, often paired with AHAs or other active ingredients. Want to level up your routine? Incorporate a product like SkinSetGo’s Kojic Acid Serum.

Our serum combines kojic acid with glycolic and lactic acids (both AHAs) for a one-two punch of exfoliation and brightening. Think of it as your shortcut to smoother, clearer, more radiant skin. Plus, the antioxidant power of THDA (a stable form of vitamin C) ensures your skin is protected while it transforms.

A Bright Idea for Your Skincare

So, is kojic acid an AHA or BHA? Nope—but that’s what makes it special. It’s not here to exfoliate; it’s here to brighten, correct, and help you feel confident in your skin.

If you’re ready to tackle hyperpigmentation or dark spots, kojic acid might just become your new best friend. And when paired with complementary ingredients like AHAs, it’s truly a skincare powerhouse.

Next time you glance at your skincare shelf, you’ll know exactly where kojic acid fits in—and why it deserves a spot in your lineup. Ready to glow? Let’s get to it!
