Kojic acid soap is a popular skincare treatment primarily used to target dark spots, hyperpigmentation, melasma, and uneven skin tone. Derived as a natural byproduct of fermenting Japanese sake, kojic acid works by limiting melanin production to safely reveal a brighter complexion.
How to Use It Safely
- Perform a patch test: Try the lather on a small patch of inner arm skin before applying to your face.
- Start slowly: Use it just 2 to 3 times a week at night to avoid severe dryness.
- Keep it brief: Massage into damp skin for no more than 30 to 60 seconds.
- Rinse completely: Ensure no soapy residue is left behind to prevent irritation.
- Moisturize heavily: Immediately follow up with a deeply hydrating moisturizer
- Apply sunscreen daily: Kojic acid increases sun sensitivity; always wear a strong SPF during the day.
