Sun sensitivity: By reducing UV-protective melanin in your skin, kojic acid makes you more sensitive to the sun, which can increase your risk of sun damage. Skin irritation: Kojic acid can dry and irritate some people's skin, especially if you already have sensitive skin.
Kojic acid can lead to contact dermatitis in some people, especially those with sensitive skin. Contact dermatitis can cause a rash, itching, and dry patches of skin. In severe cases, pain and blisters can develop. The concentration of kojic acid in creams, serums, and soaps may vary by manufacturer.
I would say no, as kojic acid soap can be really drying depending on your skin, but make sure to moisture afterwards. But based on experience it can break you out if you over use it so, you should use it only once a day if you have dry skin or only 3 times a week and have a good moisturize.
Avoid using concentrated kojic acid on your skin daily if you have hypersensitive or reactive skin. It can make your skin more sensitive to sun damage. Therefore, always follow up with sunscreen during the day. It can also dry or irritate your skin if you have allergies or sensitivity.
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.
So ironically, in wanting to protect, your body could lead you to temporarily darken. So, while kojic acid is busy working on inhibiting melanin, your body may be counteracting by stimulating it. A classic battle of skincare wits! But remember folks, this isn't a long-term effect.

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.
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].
One compatible ingredient that can be used with Kojic acid is Vitamin C. When combined, this blend of these active ingredients can boost the skin's brightening and antioxidant effects. Vitamin C helps to further inhibit melanin production and promote collagen.
Kojic acid soap can take months to show results, and it often takes up to three months for kojic acid products to work. 7 Because kojic acid soap can irritate and dry skin with persistent use, some people use kojic acid soap for a few months and then take a break to help avoid irritation.

Yes, it is generally okay to use kojic acid daily, but it should be done cautiously. Start using it a few times a week to see how your skin reacts, gradually increasing to daily use if no irritation occurs. Always follow up with a moisturizer and sunscreen, as kojic acid makes your skin more sensitive to the sun.
If you have sensitive or easily irritated skin, Kojic acid may be preferable because it is gentler and less prone to cause irritation. Retinol, on the other hand, may be better suited to people with more robust skin because it might induce early irritation and peeling.
