Long Lash Growth Serum

$ 89.00

STRENGTHEN I LENGTHEN I ENHANCE

Visibly fuller, longer-looking lashes in as little as 8 weeks — without prostaglandins or compromise.

BIOTINOYL TRIPEPTIDE-1

This powerful peptide nourishes and conditions the lashes with provitamin B5 (panthenol) and promotes hair bulb keratinocyte proliferation to ensure optimal hair anchorage. Clinical studies show 3x more volume in just 15 days!

CAPIXIL™

Our second, patented, active peptide is formulated with plant-powered red clover flower extract, rich in Biochanin A to regenerate hair follicles and improve hair regrowth to densify the lashes and brows, giving you a more full, youthful look.

REDENSYL™

This new, potent, proprietary active targets hair growth at the cellular level. Plant-based extracts and other natural ingredients dramatically reactivate hair growth and decrease hair loss with clinically visible results in 3 months by re-launching stem cell activity and proliferation and increasing the dermal papilla fibroblasts metabolism resulting in astonishing lash growth.

MYRISTOYL PENTAPEPTIDE-17

Our third peptide is a chain of 5 different peptides, hence the word Penta attached to the oil-soluble fatty acid, myristic acid for better bioavailability. It is known for being one of the best cell-communicating, active ingredients to boost keratin production (the protein that makes up hair) and lengthen the growth cycle. This results in the thicker, longer lashes and brows we all desire.

PANAX GINSENG ROOT EXTRACT (DHT BLOCKER)

Thanks to the natural compound ginsenoside, Ginseng is a super-effective hair thickener that reinforces each individual eyelash, making it very effective in thickening sparse lashes--giving the lashes and brows a full, fresh look.

CAMELIA SINENSIS LEAF EXTRACT

Also known as green tea leaf extract, it is one of the most powerful antioxidants (epigallocatechin) that stimulates and soothes the hair follicles, encouraging new growth. It has the highest concentration of plant chemicals that keep the hair follicles in the anagen phase. It also acts as a humectant by drawing moisture to the hair fibers to keep the lashes and brows moisturized and healthy.

ORGANIC CASTOR OIL

It contains ricinoleic acid, an antimicrobial, detoxifying, and moisturizing to the follicle. It helps strengthen the hair and adds shine, which gives lashes the appearance of being fuller and darker.
