Kojic acid is completely safe for all skin types at low levels and is a well-loved ingredient from dermatologists. It’s important to know that kojic acid only works to brighten dark spot pigmentation caused by trauma, acne scars, sun spots, bug bites, or scratches. It does not change the color of your skin it only helps even out skin tone from dark spots and restores the skin to its natural color.
Only when you’re using a product with high levels of kojic acid does it become an irritant and can even cause a burning sensation or rash. Dermatologists suggest a concentration of no more than 1% or less or else it can cause severe irritation and can sometimes increase the hyperpigmentation. Make sure to look for where in the ingredient list kojic acid is placed. If it’s placed in the mid to lower part of the of ingredient list then you know the product contains low levels.
