What is Feel1 Lash & Brow Serum and what makes it special?
A highly effective serum with state-of-the-art peptide technology and botanical extracts. It strengthens hair roots, improves natural density, and promotes the length of lashes and brows – entirely without prostaglandins.
Who is it suitable for?
Ideal for thin, weak, over-plucked, short, or slow-growing lashes and brows. Suitable for all ages and skin types – safe for sensitive eyes and contact lens wearers.
How is it applied?
Apply a fine line once daily along the upper lash line and to the brows – on clean, dry skin. Allow 2–3 minutes for absorption. Initial results are usually visible after 4 weeks, fully visible after 8 weeks.
How much is shipping?
Free shipping on qualifying orders.
Four active ingredients. No prostaglandins.




RADILAX-4™— four actives, one target: the root.
Lashes do not grow from the tip. Every hair sits in a follicle with its own growth cycle, and that cycle shortens with age, with makeup, and with years of extensions.
