Peter Thomas Roth Collagen Skinjection Plumping & Firming Serum, Plant-Derived Exosomes & Hyaluronic Acid

Peter Thomas Roth Collagen Skinjection™ Plumping & Firming Serum is a lightweight, science-driven serum that uses plant-derived exosomes, growth factors, and collagen-supporting ingredients to help skin look firmer, plumper, and more resilient.

This serum blends advanced biotech actives with hydrating humectants to address visible loss of volume and elasticity. Clinically tested for its ability to support the appearance of youthful fullness, the formula pairs plant-derived exosomes, growth factor and stem-cell derived signals with collagen, elastin, hyaluronic acid and glycerin to encourage the look of strength and bounce in skin. It absorbs quickly and layers well under moisturizers and sunscreen, making it easy to add to morning and evening routines.

How does this serum help skin appear plumper and firmer?

The product combines signaling ingredients and structural molecules to target lost facial fullness. Exosome-like plant vesicles and growth factor components work alongside collagen and elastin to promote the appearance of denser, more supportive tissue, while humectants draw moisture in for immediate surface plumpness.

• Plant-derived exosomes and growth factor to support visible firmness
• Collagen and elastin help improve the look of structural integrity
• Hyaluronic acid and glycerin provide hydration for instant plumping

When and how should I use the Collagen Skinjection serum?

Apply the serum after cleansing and toning, both morning and night, for best results. Use a few drops across the face and neck, gently pressing into skin until absorbed, then follow with your moisturizer and sunscreen in the daytime.

• Use 1–2 drops for thin application; increase slightly for drier skin
• Layer under moisturizers and oils without pilling
• Compatible with most actives but patch-test if using strong retinoids

What visible differences can I expect and how quickly?

Results depend on starting skin condition and consistency of use; many users notice improved surface hydration and a fuller look within weeks. Clinically tested components aim to improve the appearance of youthful volume, while long-term use can contribute to a firmer-looking texture and enhanced skin resilience.

• Immediate: increased surface moisture and temporary plumpness
• Short term (weeks): improved appearance of elasticity and fullness
• Long term: enhanced look of structural support when used consistently

Is this serum suitable for sensitive or combination skin?

The formula is designed to be lightweight and non-greasy, generally suitable for combination and many sensitive skin types. Because it contains potent biologically active ingredients, perform a patch test if you have reactive skin or are prone to irritation.

• Light texture fits well under makeup and sunscreen
• Patch-test recommended for very sensitive or allergy-prone skin
• Works well in both AM and PM routines when tolerated
