Concentrated Exfoliating Formula for Dark Spots

For a concentrated exfoliating formula aimed at reducing dark spots, consider using active ingredients known for both exfoliation and skin brightening properties.

One suitable ingredient is FruitPeel™ exfoliates cells with fruit. This natural extract blend from olive, mango, and banana peels provides gentle exfoliation and has been shown to help lighten dark spots. It is recommended for use at a concentration of 1-5% (with 3% being the recommended rate) in the water phase of your formulation. Ensure the final product pH is between 3.5 and 7.0 and avoid heating above 40°C during mixing.

Another option for enzymatic exfoliation is Bio-S Protease™ (Natural Enzymes For Exfoliation, Stabilized). This stabilized natural protease enzyme helps remove dead skin cells and promotes skin regeneration. It can be used at 0.1-5% in the water phase, avoiding heat above 40°C. It is stable across a wide pH range of 4-12.

To create a concentrated formula, you would incorporate one or both of these active ingredients into a suitable base (such as a gel, serum, or cream base) along with other necessary components like thickeners, preservatives, and humectants. The specific base and additional ingredients would depend on the desired texture and properties of the final product.
