What is it? Keratin boost is a kind of serum for eyelashes

What do you want to achieve? The serum is for those who want to prolong the effect of a Lash lift or eyelash tinting. Through the quality-assured ingredients, you get a treatment that protects the lashes and creates a natural protection and improves the treated area.

This keratin serum for lashes and eyebrows strengthens lashes and eyebrows, prevents hair loss and promotes better growth.

Advantages:

- The serum strengthens your eyebrows and eyelashes naturally and provides long-lasting results over time.

- Moisturizes and protects your lashes after a lash lift and/or tinting of your lashes.

- Works great on your brows too.

- Maintains the depth of color after you have colored your lashes.

- Gives a glossy and beautiful effect to your lashes

Disadvantage: Like all other serums, it can run into your eye if you apply too much on the brush. Therefore, apply a thin layer.

Remember! Apply a thin layer to the lashes and leave on for up to 24 hours. Can be used every day. Avoid using this boost before eyelash extensions or a lash lift as it may affect the adhesive.

Final summary: A good serum that gives noticeable results and is easy to apply. Works great for those who either dye their lashes and brows themselves or for those who do it at a salon.
