Kojic acid, derived from different types of fungi, can help to deal with dark spots on the skin or hyperpigmentation. It is a skincare ingredient with rich antioxidant and antimicrobial properties that aid you on your quest for brighter and more even complexion. The skincare industry offers kojic acid cream and kojic acid soap options to fade spots on the skin.

What is kojic acid soap?

Kojic acid soap is a soap containing kojic acid, which helps to reduce the appearance of dark spots and uneven skin tone. The acid works by inhibiting the production of melanin, a substance that produces skin pigmentation. The soap is commonly used to treat acne scars, sun spots and melasma, says dermatologist and hair transplant surgeon Dr Mohd Asif.

What are the benefits of kojic acid soap?

Kojic acid soap offers health benefits, including skin lightening and reducing hyperpigmentation.

1. Skin lightening

Kojic acid soap is widely used for its ability to lighten the skin by inhibiting the production of melanin. This makes it effective in reducing the appearance of dark spots, freckles and uneven skin tone.

2. Hyperpigmentation reduction

Kojic acid soap is known to reduce hyperpigmentation caused by melasma, sun damage or hormonal changes. It works by inhibiting tyrosinase, an enzyme that plays a role in melanin production, says the expert.

3. Acne-fighting properties

Kojic acid soap has antimicrobial properties that can help to fight acne-causing bacteria. It also helps to regulate excess oil production, unclog pores and reduce inflammation, which are all important factors in preventing and treating acne.

4. Anti-ageing effects

Kojic acid soap contains antioxidants that help reverse the damage caused by free radicals. They help to reduce the signs of ageing such as fine lines and wrinkles. The soap also promotes collagen production, which improves skin elasticity and firmness.

5. Antioxidant properties

Kojic acid soap has strong antioxidant properties that help protect the skin from environmental damage and oxidative stress. This can help prevent premature ageing, says Dr Asif.

Can you use kojic acid soap every day?

Yes, you can use kojic soap every day, but it is important to be mindful of any potential side effects or irritations. Kojic acid, the active ingredient in the soap, can cause dryness, redness or sensitivity in some individuals. So, start by using the soap every other day to know your skin’s reaction and adjust accordingly. Also, apply a moisturiser and sunscreen after using kojic acid soap.
