For optimal results, kojic acid can be used daily to address hyperpigmentation and prevent free radical damage. When combined with other exfoliating acids, limit use to 2-3 times a week to avoid irritation.
The key is to use it correctly and sparingly; be sure not to overuse kojic acid soap, as this could cause your skin to become irritated or sensitized. It's safest if you use it only once or twice a week (depending on how sensitive your skin type is), rather than every single day.
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.
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.
Though kojic acid soaps can work on most skin types, experts say that those with sensitive or dry skin should be cautious as it may sometimes cause irritation. “Those with dry skin may want to opt for soaps with moisturizing properties,” advises Dr. Gohara. “Always do a patch test before using it regularly.”
Kojic Acid can make your skin more sensitive to the harmful effects of sunlight. Hence it is advised to use sunscreen and wear protective clothing while using Kojic Acid. It is recommended to avoid tanning booths and sunlamps.
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.
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.
Effectiveness: Kojic Acid often shows results faster than Vitamin C. Skin Types: Vitamin C may not be suitable for sensitive or acne-prone skin, as it can cause breakouts.
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.
Retinol. Everyone's favorite anti-aging ingredient can bring your skin even more radiance when paired with kojic acid. Retinol is well-loved for its ability to prolong youthful skin by stimulating collagen production and boosting cell turnover. However, it's important to start very slowly due to retinol's potency.
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.
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.

SAFETY: Kojic acid is safe for topical use in concentrations of up to 1% in skin care products. Do not use longer than 3 months at a time.
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.
Salicylic acid
It is an exfoliating agent that removes dark spots and acne-causing bacteria along with dead skin cells that can lead to pigmentation.
Can I use Kojic Acid Serum in the morning? Kojic acid can make your skin more sensitive to sunlight, so it's generally recommended for use in the evening. If you choose to use it during the day, be sure to apply sunscreen with a high SPF to protect your skin.
Kojic Acid further enhances the brightening effect by inhibiting melanin production, while Niacinamide helps to improve skin texture and reduce the appearance of pores.
Kojic acid is not cytotoxic (that is not harmful to the melanocytes or pigment producing cells) & therefore cannot permanently lighten your skin color. However, most users will have a decrease in skin pigmentation with a more even skin tone, especially if combined with sun protection & other pigment reducing agents.
