Creatine 100 for Eyebrows and Eyelashes

Creatine 100 has beneficial properties for hair, including increasing moisture, restoring damaged hair, and smoothing the hair cuticle. Since eyebrows and eyelashes are hair structures, Creatine 100 can likely provide similar nourishing benefits, especially for moisture and conditioning.

The recommended usage rate for Creatine 100 in hair care is 0.5-1.4%, with 1% being the general recommendation. Using 1% or even 0.5% should be suitable for eyebrow and eyelash serums.

Preservatives for Eye Area Products

For products used around the eyes, such as mascara or eyelash serums, it is crucial to use a gentle and suitable preservative.

While some "Mild Preserved" products are gentle, the preservative specifically developed and recommended for the eye area and sensitive skin is Eye Preserved™ (Polyhexamethylene Biguanide, PHMB). It was originally developed for contact lens cleaners.

The recommended usage rate for Eye Preserved™ in cosmetic formulations is 0.5-1.5%. This would be a suitable choice for your mascara or eyelash nourishing product.
