Peter Thomas Roth Instant FIRMx Lip Filler 0.3 fl oz

Peptide-Powered Cream-to-Balm Lip Filler Treatment

The Peter Thomas Roth Instant FIRMx Lip Filler 0.3 fl oz is a rich cream-to-balm lip treatment designed to deliver immediate smoothing and long-term plumping benefits. Featuring 2% LineFill™ to create a visibly fuller lip look instantly and 1% Maxi-Lip™ peptide complex for enhanced volume with continued use, it also includes 3% Hyaluronic Acid Filling Spheres that bolster hydration and softness. The texture glides on effortlessly, leaving lips feeling supple and comforted with a natural-finish condition. Over time, lip lines appear diminished and the lip contour looks more defined and youthful. This formula offers a next-generation approach to lip care, combining high-performance actives with nourishing botanical oils and emollients.

Part of the brand’s Instant FIRMx® collection, this lip treatment addresses common signs of ageing lips—such as volume loss, fine vertical lines around the mouth, dryness and lack of firmness. According to Peter Thomas Roth, 100% of participants in a 4-hour clinical study saw an immediate reduction in the appearance of lip lines, and 91% agreed lips looked plumper with moisture in a 5-minute perception study. The formula benefits a range of skin types—normal, dry, combination and oily—and is especially suited for anyone seeking firmer, smoother lips without invasive treatments.

• Who it’s best for: Individuals experiencing lip lines, thinning lip volume, dryness or needing a smoothing lip primer.
• What makes it different: A potent combination of 2% LineFill™, 1% Maxi-Lip™ peptides and 3% Hyaluronic Acid Filling Spheres, enriched with pomegranate, coconut and squalane oils.
