10 Kojic Acid Soaps to Target Discoloration, Hyperpigmentation, and Skin Damage
Is it just us or are dark spots so hard to eliminate? Yes, there are plenty of holy grail products like the Remedy for Dark Spots serum that take care of pigmentation and discoloration. But these treatments — which often include acids and exfoliants — can sometimes be too heavy and rough on the skin. Are there any treatments for hyperpigmentation and acne scarring that won't cause those with sensitive skin redness and contact dermatitis? Enter: kojic acid and particularly, kojic acid soaps.
Kojic acid, a gentle and lightweight skin-care ingredient, is a potent antioxidant derived from fermented mushrooms. Like its sister ingredients, glycolic acid and salicylic acid, kojic acid has anti-aging and anti-inflammatory properties, helps boost elasticity in your skin, and eliminates fine lines and wrinkles. Its true selling point, however, is how well it can tackle dark spots. This antioxidant works to lighten hyperpigmentation and reduce melanin production, all of which help minimize discoloration, acne scarring, and even sun spots.
Kojic acid comes in many forms, from serums to creams and the aforementioned soaps. If you're ready to add kojic acid to your skin-care routine, we suggest starting with a kojic acid soap because it's less intense. And lucky for you, we have the 10 best kojic acid soaps for every skin concern listed below. Keep scrolling to shop our favorites.
Best Overall Kojic Acid Soap
Valitic Kojic Acid Dark Spot Remover ($17)
This bar deserves all its hype and more. Its innovative formula combines turmeric, kojic acid, hyaluronic acid, and a slew of other skin ingredients to help lighten dark spots, soothe redness, and even out your skin tone. It's free of parabens and sodium lauryl sulfate, and it's gentle (but also effective!) enough to be used on your hands, bikini area, and underarms.
Best Gentle Kojic Acid Soap
Kojie San Skin and Body Brightening Soap ($10)
Kojic acid is great for evening skin and eliminating dark spots but it is still an acid, and we know skin-care acids can sometimes be too irritating on the skin. That said, there are gentle and effective kojic acid soaps that'll work on even the most sensitive skin, like the Kojie San Skin Brightening soap. With its formula consisting of glycerin, tea tree, and other soothing ingredients, this bar will cleanse your skin and target your dark spots without causing redness or inflammation.
Best Kojic Acid Soap for Dark Spots and Hyperpigmentation
Topicals Faded and Brightening Cleansing Bar ($28)
Topicals has done it again. If you're a fan of their TikTok-viral dark-spots serum, then you'll love their faded and brightening cleansing bar. It has kojic acid, of course, and other brightening ingredients like lactic acid to specifically target dark spots. Plus, a touch of shea butter and urea to keep your skin smooth and refreshed. The bar also smells hella nice, which is a bonus in our books.
Best Kojic Acid Soap for Acne Scars
Healov Kojic Papaya Face and Body Wash ($7)
Kojic acid doesn't specifically target acne scars, but it does help diminish skin damage like acne scars. We chose this one because it's specifically formulated with kojic acid to reduce discoloration and has acne-treatment ingredients like papaya, tea tree oil, and glycerin to repair skin damage.
Best Kojic Soap for Brightening
Koji White Pure Kojic Acid Skin Brightening Soap ($10)
If you're looking for the brightening soap, look no further than this kojic acid soap. The soap has 5 percent kojic acid and 1 percent vitamin C, which makes it uber-strong and effective for brightening (but also harsh on sensitive skin). Luckily, it has anti-inflammatory ingredients like hyaluronic acid to soothe any redness and keep your skin fresh and moisturized.
Best Fragrance-Free Kojic Soap
Body Restore Kojic Acid Soap Bar ($10)
Finding fragrance-free products is a struggle. But a fragrance-free kojic acid bar? That's a whole 'nother ball game. Luckily, the Body Restore bar exists and it's both fragrance-free and heavily concentrated with kojic acid, vitamin C, vitamin E, and retinol to boost dewiness. It doesn't get better than this — seriously.
Best Kojic Acid Soap for the Body
The Takesumi Bright Bar with Kojic Acid ($19, originally $25)
Underarms, bikini area, hands, elbows — this beauty works on almost any body area where pesky dark spots just! won't! fade! away! It's vegan and cruelty-free and uses natural ingredients like kojic acid, sea salt, and licorice root extract to brighten skin, eliminate odor (cool, right?), and reduce inflammation.
Best Kojic Acid Soap for Every Skin Type
Urban Skin Rx 3-in-1 Even Tone Cleansing Bar ($19)
The perfect kojic acid bar doesn't exist . . . unless it's the Urban Skin Rx cleansing bar. It contains a trio of brightening ingredients including kojic acid, niacinamide, and azelaic acid that evens out your skin and gives you a dewy glow. The bar has a nice lather that doesn't feel too heavy on dry skin, but can also get all that dirt and residue left behind on oily or combination skin.
Best Liquid Kojic Acid Soap
Koji White Brightening Moisturizing Body Wash ($17)
Not a fan of bar soap? Some folks prefer a liquid version and that's OK! We chose the Koji White body wash not just for its dazzling reviews (though those count, too) but mainly for its ah-mazing formula. This body wash is infused with four flower extracts, kojic acid, vitamin E, vitamin B5, and hyaluronic acid, and it's designed to treat discoloration and keep your skin nice and smooth.
Best Lather
BLgoals Dark Spot Remover Kojic Acid Turmeric Retinol Soap ($6, originally $15)
Some soaps simply don't have a good lather, no matter how much you add water or scrub. There's just no foam. Not this bar, though. It's concentrated with .09 percent kojic acid and .07 percent turmeric, feels super soft on the skin, and lathers up to perfection, according to reviewers. It's definitely a worthy addition to your skin-care routine.
