Kojic Acid Serum Benefits and Uses: Why This Face Serum Is a Game-Changer for Your Skin

If you've been dealing with hyperpigmentation, dark spots, scars and uneven skin tone, then kojic acid is the answer you've been looking for. As a lightening agent, it functions by preventing the synthesis of melanin, the pigment that gives our skin its colour. It's also an antioxidant that works to protect the skin from environmental harm brought on by UV radiation and pollution. "The Cosmetic Ingredient Review Expert Panel deemed kojic acid safe for cosmetic use at concentrations up to 1%. Furthermore, its anti-aging properties improve the look of aged skin. Its antimicrobial action combats acne-causing bacteria and treats fungal infections such as athlete's foot, yeast infections, and ringworm", shares Dr Gupta. This under-the-radar skincare superhero is garnering attention in 2024. India's leading celebrity and bridal makeup artist, Bianca Louzado shares that she loves kojic acid for her skin. "I've battled with hormonal acne and kojic acid has been a saviour with its gradual but definite results over time. It is a sure shot route to control acne and prevent breakouts." It's a gentle exfoliator that promotes skin cell turnover, contributing to a smoother radiant complexion. "But yes, always use sunscreen after as it can increase skin sensitivity to the sun", explains the makeup maestro.

Kojic acid can be found in various cosmetic formulations, including serums, masks, creams, soaps, cleansers and even powder. "If I had to choose, I would recommend serums for more effective results", shares Louzado. Serums typically have a higher concentration of active ingredients, allowing for deeper penetration and more noticeable results. They can be easily incorporated into your daily skincare routine and reap great benefits. By nature, kojic acid has a drying effect and can irritate the skin. Using it in serum can balance the drying effect as they can always be layered with other products like moisturisers and sunscreens. Louzado adds, "I love using kojic acid in face masks when travelling, as they are super lightweight and easy to use. They can provide a quick hydration boost. However, they do not deliver the same level of potency or consistent results quite like a serum."

Dr Gupta suggests limiting the use of kojic acid to 2-3 times per week if combining it with other exfoliants like glycolic acid. This would prevent over-exfoliation. "Avoid excessive application; overuse increases the risk of side effects. Apply only to hyperpigmented areas on the face, chest, or hands, keeping it away from the eyes, lips, and mouth." Loved by several dermatologists, Dr. Kiran Sethi, a board-certified dermatologist and India's leading expert in cosmetic dermatology also shares – "I find kojic acid to be a very safe ingredient and effective for more superficial pigmentation. Many patients swear by its efficacy." Its benefits extend to its application when prepping your skin for makeup. According to Louzado, you should start with your regular cleansing routine. Then apply 3 drops of kojic acid serum and gently massage it into the skin. "Focus on areas with hyperpigmentation or uneven skin tone." Finish off with a lightweight moisturiser to hydrate and do not forget to apply sunscreen. "Once the serum and moisturiser are well absorbed, proceed with your makeup routine. A well-prepped skin allows for long-lasting make-up." Before you stretch to buy this phenomenal ingredient, we recommend consulting your dermatologist to establish what works best for your skin. Regardless, always start with a patch test.
