Physicians Formula Eye Booster Lash-Enhancing 2-in-1 Eyeliner Serum — Black, Long-Wearing & Hypoallergenic

Physicians Formula Eye Booster is a dual-action black liquid eyeliner that defines the lash line while delivering a lash-conditioning serum at the base of your lashes.

This innovative 2-in-1 formula combines the instant precision of a long-wearing liquid liner with a Lash Boosting complex designed to nourish and visibly lift the appearance of lashes where they meet the eyelid. The high-tech Japanese blend resists smudging and light moisture, and the product is dermatologist approved, hypoallergenic, cruelty-free, and vegan—safe for sensitive eyes and contact lens wearers.

How does this product give both eyeliner and lash care in one step?

The pen delivers a pigmented liquid line while releasing a targeted serum at the base of lashes, so you line and treat simultaneously. The applicator deposits color and active ingredients precisely along the lash root for maximum contact.

• Dual-delivery formula: pigment plus Lash Boosting complex.
• Thin, controlled tip for accurate application along the lash line.
• Serum concentrates at lash base where growth-supporting ingredients work best.
• Works with daily makeup routine—no extra step needed.

Will this eyeliner stay put during a busy day?

The Eye Booster uses a water-resistant, long-wearing Japanese formula engineered to resist smears and maintain crisp lines. It tolerates normal humidity and daily wear while keeping color intact for hours.

• Smudge-resistant pigment maintains definition.
• Water-resistant finish for everyday environments.
• Quick-dry texture reduces transfer to lids and under-eye areas.
• Ideal for both subtle and bold looks without frequent touch-ups.

Is this suitable for sensitive eyes and contact lens wearers?

Yes—this liner is dermatologist tested and hypoallergenic, formulated without over 150 known harsh ingredients. It’s fragrance-free and designed to be gentle on delicate eye skin and compatible with contacts.

• Dermatologist-approved and clinically tested for tolerance.
• Fragrance-free, paraben-free, and gluten-free formulation.
• Hypoallergenic and safe for sensitive eyes and contact lenses.
• Vegan and cruelty-free manufacturing standards.

How do I apply the Eye Booster for best results?

For a precise line, glide the pen tip from the inner corner to the outer corner close to the lash base. For added lift, trace slightly thicker at the outer third of the eye and allow the serum time to settle into the lash roots.

• Start with clean, dry lids for smoother application.
• Use short strokes for a defined, even line.
• Apply daily for continuous conditioning benefits at the lash base.
• Pair with mascara or let the liner be the focal point for minimal looks.

Who is this for: This 2-in-1 liner is for anyone wanting precise, long-lasting black definition plus added lash care without extra steps—especially people with sensitive eyes, contact lens wearers, or anyone seeking cruelty-free and vegan makeup options. It’s a convenient pick for busy mornings, makeup minimalists who want a polished eye quickly, and makeup lovers who value multi-tasking products that reduce routine complexity.
