Rejuvala Lash & Brow Growth Serum
Rejuvala Lash & Brow Growth Serum is a non-hormonal, ophthalmologist-safe dual-action formula designed to visibly enhance the fullness and definition of both lashes and brows. Powered by biomimetic peptides, biotin, keratin-building amino acids, and pro-growth botanicals, it helps strengthens hair fibers while supporting natural growth without the risks of prostaglandin analogs.
Biomimetic peptides + biotin + keratin = strength + growth + resilience
This innovative formula promotes keratinocyte proliferation in the hair bulb to support visible growth. It also stimulates Laminin V and Collagen IV, two natural anchoring proteins that help keep hair firmly rooted — reducing shedding and improving the appearance of volume.

Peptides + Biotin
This dual-action serum supports the natural growth cycle of lashes and brows by energizing the hair root and strengthening the ‘anchor’ that holds each strand in place. Powered by biomimetic peptides and amino acids, it promotes visible volume and definition without the risks of hormonal ingredients.
The result? Lashes and brows that appear stronger, thicker, and more defined — with no redness, discoloration, or irritation.
One Formula – Two Uses
Designed for both lash and brow enhancement to streamline routines.

The Science Behind
Rejuvala Lash & Brow Serum
This dual-action serum supports the natural growth cycle of lashes and brows by energizing the hair root and strengthening the ‘anchor’ that holds each strand in place. Powered by biomimetic peptides and amino acids, it promotes visible volume and definition without the risks of hormonal ingredients.
Keratinocyte Proliferation in the Hair Bulb
Keratinocytes are the main cells that make up your hair and skin. In the hair bulb (the base of the hair follicle), these cells divide and mature to form the hair shaft.
Your lashes and brows grow when special skin cells called keratinocytes multiply in the hair root. More of these cells = stronger, thicker hair strands.
Laminin V and Collagen IV
Adhesion Molecules for Hair Anchoring
Laminin V and Collagen IV act like the grip tape or glue at the base of your lashes and brows. Stimulating them helps keep each hair anchored longer — reducing fallout and improving lash/brow fullness.
