   Increases the expression of keratin genes (KRT1, KRT14, KRT71), essential for strong hair fiber production.

2. Anagen Phase Stimulation

   Promotes and prolongs the active (growth) phase of the hair cycle, enhancing visible lash and hair thickness.

3. Improved Hair Anchoring

   Strengthens the dermal-epidermal junction to reduce lash and brow fall-out.
