Peter Thomas Roth Instant Firm Lip Filler Plumping Peptide Complex, in a convenient 10 ml tube, is a hydrating lip treatment designed to visibly amplify lip volume while nourishing and smoothing the lip surface. The cream-to-balm texture melts on contact, leaving lips moisturized, soft, and supple as you wear it.

This lip plumper combines a targeted peptide complex with hydrating spheres to deliver instant results and lasting improvements in lip fullness and the look of lip lines — ideal for anyone noticing signs of visible lip aging.

How it works

• 2% LineFill technology peptides provide an immediate plump while supporting continued volume enhancement over time.
• 1% Maxi-Lip helps refine lip contours and maintains moisture for a fuller, more defined look.
• 3% Hyaluronic Acid Filling Spheres release hydration to smooth the lip surface and soften the appearance of lines.
• Oils of pomegranate, coconut, and squalene nourish, soften, and seal in moisture for comfortable wear.

Texture and experience

The formula is a creamy, balm-like texture that glides on easily and transforms into a satin-milk finish. It delivers temporary plumping while maintaining a lightweight, non-sticky feel, making it suitable for layering under lipstick or wearing alone.

Who this is for

Ideal for anyone looking to diminish visible lip aging and achieve a fuller, more youthful lip appearance. Suitable for all skin types, whether you want a daily lip treatment or a prep step before makeup.

How to use

• Apply a thin layer to clean lips as a standalone treatment or as a primer under lip color.
• Use daily to maximize both instant effects and long-term improvements in lip fullness and smoothness.
