Still battling the stubborn pigmentation summer left behind? As monsoon rolls in with humidity and dull skin days, dermatologists turn to kojic acid to fade post-summer tans and prevent uneven pigmentation. Derived from fungi, kojic acid works by inhibiting tyrosinase — the enzyme responsible for melanin production — helping your skin return to its natural tone. At Pokonut, we use this science-backed ingredient to formulate skincare that works with Indian skin needs.
Kojic acid is a quiet powerhouse when it comes to fading dark spots and brightening dull skin. Whether the issue is sun damage, leftover acne marks, or the lackluster tone that often comes with the rainy season, kojic acid works below the surface to even things out. A concentration of 1% to 2% hits the sweet spot—it’s effective without being harsh, making it safe for daily use and easy to slip into your routine with products like Pokonut’s Kojic Acid Soap.
Why Dermatologists Recommend Kojic Acid for Monsoon-Season Pigmentation?
As monsoon clouds take over the harsh summer sun, skin begins to show the aftereffects — uneven tone, persistent pigmentation, and post-acne marks triggered by sweat and clogged pores. Kojic acid is a go-to solution recommended by dermatologists during this season to tackle hyperpigmentation safely and effectively.

FAQs
Q1. Can I use kojic acid during the monsoon?
Yes, in fact, it’s ideal! The monsoon’s lower UV index reduces risk of sensitivity, making kojic acid even more effective and safer with sunscreen.
Q2. Will it help clear acne marks and dull skin post-summer?
Absolutely. Kojic acid treats post-inflammatory hyperpigmentation, which includes acne scars, and restores skin glow dulled by sweat and clogged pores.
Q3. What makes it better than other tan removal ingredients?
It offers antioxidant, anti-inflammatory, and antimicrobial benefits beyond tan removal — all of which make it monsoon-skin-friendly.
Q4. Should I stop using it once my tan fades?
You can reduce frequency, but continuing low-dose use helps prevent future pigmentation and keeps skin bright.
Q5. What should I avoid pairing with kojic acid?
Avoid alcohol-based toners, physical exfoliants, or strong acids when starting out. Build your routine slowly to avoid irritation.
