Kojic Acid Soap for Dark Spots, Uneven Tone & Ingrown Marks
Meet the Kaia Naturals Kojic Acid Brightening Bar — a targeted body cleansing bar made to help visibly improve the look of uneven tone, dark spots, underarm discolouration, post-shave marks, and areas of dullness while you shower.
Formulated with kojic acid dipalmitate, a stabilized form of kojic acid, plus licorice root extract and sea salt, this brightening body bar is a simple first step for smoother-looking, more even-toned skin.
Best for targeted areas like:
- Underarms
- Inner thighs
- Knees and elbows
- Hands
- Buttocks
- Post-shave or ingrown hair marks
- Areas of uneven tone or dullness on the body
Why this kojic acid bar works
- Kojic Acid Dipalmitate — a stabilized form of kojic acid used to help improve the look of dark spots and uneven pigmentation.
- Licorice Root Extract — a botanical brightening ingredient often used to support a more even-looking skin tone while helping calm the look of irritation.
- Sea Salt — helps refresh the skin and support a clean-feeling finish, especially for areas prone to sweat and odour.
How to use
Use daily in the shower on targeted areas such as underarms, knees, elbows, inner thighs, hands, or areas with visible uneven tone. Massage onto damp skin, allow the lather to sit briefly, then rinse thoroughly. Follow with moisturizer or body care as needed.
For underarms, allow skin to adjust gradually, especially after shaving. Avoid using on broken, freshly waxed, or irritated skin.
Pair it with Step 2 for best results
For a complete underarm brightening routine, pair this bar with the Kaia Naturals Takesumi Bright Niacinamide Brightening Deodorant . The bar cleanses and preps the skin, while the deodorant balm helps continue the brightening routine between showers.
