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. Some people may also use kojic acid soap every other day to help avoid irritation.
Kojic acid especially the soap, is far too harsh to use multiple times a day. The results will inevitably be dryness, a damaged skin barrier and often worsening. 1-3 times a week, for a maximum of one minute is the sweet spot! Make sure to increase your SPF too!
The timeframe for seeing results with kojic acid can vary based on several factors, including the concentration of kojic acid, your skin type, and how consistently you use the product. Generally, users may start to notice initial improvements in their skin tone within 2-4 weeks of regular use.
On the other hand, certain ingredients can trigger irritation and should be avoided if you're using kojic acid in your skincare routine. Harsh acids, like alpha-hydroxy acids (AHAs), are a prime example, as well as certain retinoids.
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.
How long does kojic acid take to work topically? Results will not happen overnight. Although some people may see results after a few weeks, on average it will take 1-2 months of consistent topical use of kojic acid before you begin to see improvements. Remember - consistency is key for optimal results.
Risks and Precautions
Skin irritation: Kojic acid can dry and irritate some people's skin, especially if you already have sensitive skin. Allergies: Some people experience allergic reactions to kojic acid, resulting in an itchy and dry skin rash called contact dermatitis.
Moisturize: Follow up with a nourishing moisturizer to seal in the benefits of kojic acid and keep your skin hydrated. Sunscreen (AM only): Since kojic acid can increase sun sensitivity, always finish with a broad-spectrum sunscreen during the day.
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.
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.

What's the Right Way to Use Kojic Acid Soap? Start Slow: Initiate with a twice-weekly routine, and gradually transition to once or twice daily as your skin gets accustomed. Master the Application: Generate a lather and apply uniformly on the face or body.
Kojic Acid is for external (for skin use) use only. Avoid contact with eyes, eyelids, lips, mouth, and nose. If the medicine comes in contact with any of these areas, rinse with water immediately. In some cases, you may experience irritation, itching, or burning sensation at the application site.
