Glycerin vs. Sodium Hydroxide

If you are searching for a natural, gentle, and restorative bar soap, look no further than Koji White!


Our kojic acid-infused bar soaps are gentle and effective for both your face and your body, and they aren’t just bestsellers for hyperpigmentation. We are proud to be the #1 facial cleansing bar on Amazon in both the US and Canadabeating out some of the biggest brands in the skincare industry! 


The Difference Glycerin Makes in Our Soap

Unlike our competitors, Koji White soap and skincare products are formulated with glycerin instead of sodium hydroxide. Sodium hydroxide is a common ingredient in bar soap. While it may not irritate your skin immediately, using sodium hydroxide soap long-term can dry, damage, and irritate your skin. This may be why your face and body remain dry no matter how much moisturizer you apply.


Glycerin is a naturally derived humectant, so it helps your skin retain moisture. It has a low pH level, so it won’t strip your skin. Being that it’s gentle, glycerin is safe for all skin types—including dry and sensitive skin. Our proprietary formula also moisturizes and softens while cleansing and brightening but be sure to apply serum and moisturizer after you shower or wash your face.

The Koji White Philosophy

We aren’t just the best soap for hyperpigmentation, as the Koji White brand is committed to supporting your conscious lifestyle. While competing beauty brands prioritize results over sustainability, we deliver results and ethics. So, there’s no need to compromise!


Our products are environmentally conscious and are the ideal addition to your clean skincare routine. Koji White’s results outperform top bar soap brands and department store beauty brands.

In addition to using natural glycerin, our products are also:

  • Vegan and cruelty-free—our products aren’t made with animal byproducts and are never tested on animals.
  • SLS, sodium hydroxide, mercury, and paraben-free—our products contain natural ingredients that are safe and gentle for all skin types.
  • Dermatologist-approved—our products are dermatologist-approved and non-comedogenic, so they won’t clog your pores.


The benefits of using glycerin soap on your skin cannot be overstated. Unlike sodium hydroxide, which can be harsh and drying, glycerin is a gentle ingredient that provides hydration and nourishment to even the most sensitive skin. Glycerin soap is appropriate for all skin types, whether you have dry, oily, or acne-prone skin. It can help resolve any skin problems while leaving your skin soft, smooth, and shining. Glycerin is an essential element for anyone seeking gentle and effective skincare because of its natural qualities.
