How do I mix and apply the two components?

Do not mix or apply the components for eyebrow or eyelash use. Current manufacturer precautions explicitly prohibit use on those areas.

What comes with the single-use bleach?

The kit contains 0.7 g of Step 1 powder, 3 g of Step 2 cream, an application brush and protective skin-guard cream.

When should I use the included skin-guard cream?

The included skin-guard cream does not override the current precaution prohibiting use on eyebrows or eyelashes.

Can I save the mixed bleach for another application?

No. Any mixed product should be discarded immediately rather than sealed or stored.

Does the formula contain fragrance?

Yes. Fragrance is declared in the Step 1 powder.
