If you’ve been battling uneven skin tone, stubborn dark spots, or dull skin, kojic acid serum might just be your skin’s new best friend. In this guide, we’re diving deep into what makes kojic acid serum a must-have in your skincare arsenal, how to use it, myths debunked, top recommendations, and FAQs.

Kojic acid is a natural compound derived from fungi, particularly Aspergillus oryzae, also known as “koji mold.” It’s also a byproduct of the fermentation of rice, soy, and sake.
How Does Kojic Acid Work on the Skin?
What is Kojic Acid?
This powerhouse ingredient works by inhibiting the production of tyrosinase, an enzyme responsible for melanin (pigment) formation. Less tyrosinase = less melanin = brighter, even-toned skin.
Top Benefits of Kojic Acid Serum
1. Fades Dark Spots and Hyperpigmentation
Whether it’s sun spots, age spots, or post-acne marks, kojic acid serum works to lighten pigmentation and bring your natural glow back.
2. Treats Melasma
Melasma is a stubborn skin condition often caused by hormonal changes. Kojic acid serum penetrates deeply to fade the patchiness over time.
3. Brightens Skin Tone
Want that lit-from-within glow? Kojic acid serum targets dullness and revives tired skin.
4. Fades Acne Scars
Those leftover acne scars don’t stand a chance. With consistent use, kojic acid helps break down residual pigmentation from breakouts.
How to Use Kojic Acid Serum (Step-by-Step)
Step 1: Cleanse
Start with a clean face. Use a gentle face wash that doesn’t strip your skin.
Step 2: Apply Serum
Take a few drops of kojic acid serum and apply it evenly on your face, focusing on dark spots or uneven areas.
Step 3: Moisturize
Follow with a moisturizer to lock in hydration.
Step 4: Don’t Forget Sunscreen
