Do not use the soap directly on your face. First wet the soap with lukewarm water and work up a lather. Then massage the lather onto your neck and face, avoiding the eyes and mouth. Wash your face for not more than 30 seconds and rinse with cold water.
Use Gentle Cleansing Techniques
This means not applying it directly to your skin, and instead lathering the soap in your hands and then applying it to your damp face. Even with this gentle technique, kojic soap's deep cleansing capabilities can wash off excess makeup, oil, and dirt.

In severe cases, pain and blisters can develop. The concentration of kojic acid in creams, serums, and soaps may vary by manufacturer.
Kojic acid is generally suitable for all skin types. However, if it is combined with other exfoliating acids like glycolic acid, it is recommended not to use it every night to avoid over-exfoliating the skin. Kojic acid can cause irritation or contact dermatitis if the concentration is too high.

Yes, kojic acid is safe to use everyday. Depending on your skin's sensitivity, it can be used twice a day. Just remember, don't use kojic acid more than 3 months at a time because that can be damaging to your skin.
Kojic acid captures copper ions, preventing the activation of tyrosinase, thus preventing the formation of melanin [12,14]. Due to its tyrosinase-inhibiting activity, KA is considered one of the most effective skin lightening agents in the beauty industry [15].
Glycolic Acid
It is an alpha-hydroxy acid (AHA) derived from sugarcane. In low concentrations, glycolic acid produces desquamation of pigmented skin cells. About 30 to 70 per cent of glycolic acid can enhance the penetration of other skin lighteners such as HQ.
If you stop using kojic acid, your skin may gradually return to its original state, particularly if the underlying causes of hyperpigmentation are not addressed. To maintain the results, it's important to integrate kojic acid into a continuous skincare routine.

High Concentrations of AHAs/BHAs: The Acid Overload
Now, let's talk about AHAs (Alpha Hydroxy Acids) and BHAs (Beta Hydroxy Acids). They're fantastic for exfoliation and clearing up your skin, but here's the kicker: when you mix them with kojic acid in high concentrations, it's like a bad acid trip… literally.

Even people with dry skin to get maximum benefits of active ingredient Kojic acid can go for serums. To combat dryness, they can add Hyaluronic acid before kojic acid and apply a non-comedogenic moisturizer after Kojic acid serum.
Both are available over the counter and inhibit melanin production. However, Kojic acid is considered more potent and is thus a preferred choice for more stubborn hyperpigmentation.
