Kojic acid is a type of skin-lightening agent that is commonly used in skincare products to improve the appearance of hyperpigmentation and uneven skin tone. But how does it work, and is it worth adding to your skincare routine? 

How does kojic acid work?

Kojic acid works by inhibiting the production of pigment in the skin, which can help to lighten hyperpigmentation and even out the skin tone. It does this by blocking the enzyme tyrosinase, which is responsible for the production of melanin (the pigment that gives our skin its color). By inhibiting tyrosinase, kojic acid can help to reduce the appearance of dark spots and other forms of hyperpigmentation.

Pros of using Kojic Acid in your skincare routine:

• Lightens hyperpigmentation: Kojic acid can help to lighten hyperpigmentation, making it a popular choice for those looking to improve the appearance of dark spots and uneven skin tone.
• Suitable for all skin types: Kojic acid is generally considered to be safe and suitable for all skin types. However, it's always a good idea to patch test any new products before using them on your entire face, and to pay.
