Kojic Acid & Turmeric Soap

01 · Key ingredients, honestly

• Kojic acidTone

  limited evidence

  Slows tyrosinase, the enzyme behind pigment. But here it is the last ingredient and it rinses off after a minute, so expect far less than a leave-on kojic serum. Can irritate sensitive skin.

• Turmeric powderAntioxidant

  insufficient evidence

  Curcumin has lab data on pigment and inflammation, and a few small studies on leave-on creams. In a wash-off bar the effect is likely small. It can tint towels and light skin yellow.

• Lemon oilWatch for

  limited evidence

  Adds scent. Cold-pressed lemon oil can make skin more sensitive to sun and is a common irritant. Rinse well and wear sunscreen.

• Shea, cocoa and mango butterEmollient

  limited evidence

  Rich butters that make the lather feel less stripping. Some stays on skin after rinsing.

• Glycerin and sorbitolHumectant

  well-supported

  Humectants high in the list that keep the bar from drying skin out as much as a plain soap.

• Saponified coconut and palm oilCleanser

  well-supported

  This is the soap itself: oils turned into soap with lye. Cleans well, but true soap is alkaline and can feel tight on dry skin.

Plain truth: this is a pleasant brightening-themed wash, not a strong dark spot treatment. For real evidence, pair it with a leave-on like niacinamide.

02 · Who it's for

• Normal or oily skin that handles actives well.
• Anyone who likes a brightening wash for face or body.
• Not a fit for reactive skin: it has lemon oil and kojic acid. The Sensitive Skin Receipt is the better pick.

03 · How to use

Work into a lather with water, apply to face or body, leave it on 30 to 60 seconds, then rinse. Start once a day. Follow with moisturizer and, in the daytime, sunscreen.

Contains lemon oil. Avoid sun on treated areas without sunscreen.
