Frequently Asked Questions

  • Start with clean, dry skin. Comb product through brows with spoolie. Glide brush along base of lashes. Allow product to dry down before applying other products.

  • You should use the Kitsch Densifying Lash & Brow Boost Serum right after cleansing and toning your face (your skin must be 100% dry!) and before applying any moisturizers, facial oils, eye creams, or nighttime treatments. Moisturizers and creams create a barrier that prevents the Densifying Lash & Brow Boost Serum formula from reaching the hair follicles. For the best results, it should be the first leave-on product you apply after washing your face.

  • No, the Kitsch Densifying Lash & Brow Boost Serum should be used on clean, dry brows and lashes.

  • One single dip provides enough serum for both upper lash lines. You only need a thin, dampened line; the brush should not be dripping.

  • One dip per eyebrow. Use the spoolie to distribute the serum evenly through the hair and onto the underlying skin.

  • Once daily. Applying more than once a day will not speed up results and may lead to product buildup or minor irritation.

  • A little goes a long way. If the serum is running into your eyes or feels "gloopy" on your brows, you are likely using too much. One standard dip is designed to deliver the perfect dose of active ingredients for a single application.

  • You should rinse immediately if contact with eyes occurs, and you should avoid direct contact with eyes.

  • You should discontinue use if any irritation occurs. And please note, this product is not for use on sensitive skin.
