Why You'll Love It

• Biotin — A key B vitamin that supports keratin production, the structural protein essential for strong, healthy brow hair growth
• Hydrogenated Castor Oil — A deeply conditioning emollient that nourishes and moisturizes brow hairs and the underlying follicles to support healthy growth
• Glycerin — A humectant that hydrates the brow area, keeping the skin supple and creating an optimal environment for hair growth
• Precision Brush Applicator — Ultra-fine tip allows for targeted, mess-free application directly to sparse areas for maximum efficacy
• Lightweight & Fast-Absorbing — Clear, non-sticky formula absorbs instantly and can be worn under makeup or alone

How to Use

Cleanse and dry the brow area. Using the precision brush, apply a thin layer of serum along the brow line and into sparse areas. Use morning and/or evening. Allow to absorb before applying makeup. For best results, use consistently for 4–8 weeks.
