Most brow and lash serums use isopropyl cloprostenate — a synthetic prostaglandin analogue with documented side effects including iris colour change and periorbital fat atrophy. This serum uses castor oil (ricinoleic acid supports prostaglandin-pathway follicle stimulation) and vitamin E — natural compounds without pharmaceutical side effects.
✦ Ingredient Spotlight: Castor Oil
Castor oil's ricinoleic acid activates prostaglandin E2 receptors — the same pathway targeted by pharmaceutical hair and lash growth compounds. It also has documented antimicrobial properties and is one of the few single-ingredient oils with meaningful peer-reviewed evidence for hair, lash, and brow growth.
Full Ingredient List
Castor Oil (Ricinus Communis), Vitamin E (Tocopherol), botanical plant extracts (brow and lash serum)
How to Use
Apply a thin layer along the brow line or lash base nightly using the wand. Allow to dry before contact with pillow. Use consistently for 6–8 weeks to assess results.
