Why do I see an oil-like consistency separated from the color on top of my pigments? 

Biotouch pigments, with over 40 years of quality testing, stand out as the safest in the permanent makeup industry. Formulated with glycerin oil, these pigments remain thick and moist and don't dry out for days. In case of separation, blend the pigment powder with the oil by shaking the bottle upside down vigorously. Unlike watery bases, our highly concentrated pigments do not require beads for blending. For optimal consistency and best color retention results, store pigments upside down to ensure the highest concentration when ready for use.

Why does the color pigment when squeezed out of the bottle appear diluted?

It appears diluted because it has NOT been shaken thoroughly. Color pigment needs to be shaken vigorously for over 20 times. Tighten the cap and with the bottle upside down, shake with full strength. Please be aware that the glycerine always sets at the top of the bottle to keep the pigment moist, this is why it needs to be shaken VERY WELL.

Why do two of the same Microblading Pigments appear different in color when the bottles are compared side by side?

A pigment is a group of compounds that changes color as the result of wavelength-selective absorption. The initial drop can dominate the bottle wall which makes the color appear slightly different. Just shake the lighter color VERY well until it matches the darker color, test by putting a drop on skin, smear and rub the color a few times, the true color will then appear the same

Can both sides of the eyebrows result in different darkness? 

Yes, if too much time is invested on one side of the eyebrow, the color will start oxidizing after 30 min. and one side might appear lighter.

Why does pigment color on skin fade or change over time? 

Color fades or changes due to lifestyle, skincare products, and health issues. Someone who does outdoor activities, lots of sun exposure and swims in chlorinated pools color will fade faster.

Why does color darken on the brows immediately after the permanent make-up procedure? 

After the procedure, the color heavily builds up on top of the surface of the skin so it appears much darker. When skin is traumatized, scabs form and they are normally brown. Once the scab peels off in 1-2 weeks, the true color will remain in the dermis layer and the Color retention will be about 30%-70% depending on the skin tone and color pigment used.
