The Target: Who is The Peter Thomas Roth Collagen Skinjection Plumping & Firming Serum Best For?
If your skin’s bounce has gone on an extended vacation, consider this serum the invitation to call it back. It’s a wonderful fit for normal, dry and combination skin, especially if you’re noticing fine lines, dullness or a little loss of firmness and elasticity. The lightweight fluid texture makes it an easy daily step for anyone who wants plumper, fuller-looking skin, and the fragrance-free formula keeps your routine simple and comfortable.
The Formula: Key Ingredients & Clinical Claims
Peter Thomas Roth built this serum around plant-derived exosomes, growth factor and stem cells, then layered in collagen, elastin and hyaluronic acid for plump-looking, well-hydrated skin.
- Plant-Derived Exosomes, Growth Factor & Stem Cells: This is the headline complex, drawing on goji berry and a growth factor peptide to target the look of collagen loss. It gives skin a fuller, more resilient appearance and is the reason this serum earns its Skinjection name.
- Collagen & Elastin: Hydrolyzed collagen, soluble collagen and hydrolyzed elastin add to the plumping and firming feel. Skin looks bouncy, supple and full of youthful volume.
- Hyaluronic Acid & Glycerin: Sodium hyaluronate and glycerin draw moisture into the skin so your complexion looks hydrated, smooth and plump while feeling strong and resilient.
The Experience: Texture, Scent, and Finish
Out of the bottle, you’ll find a lightweight fluid serum with a silky glide that spreads easily over clean skin and sinks in quickly. It’s fragrance-free, so there’s no scent to compete with the rest of your routine, just a clean, comfortable feel. As it settles, skin looks smooth, hydrated and softly plumped with a fresh, healthy finish. Your moisturizer and SPF layer right on top, and makeup sits smoothly over it too.
The Benefits: Immediate vs. Long-Term Results
Immediate Results: Skin feels hydrated and looks plumper and smoother within minutes, with a fresh, healthy-looking finish.
Long-Term Gains: With consistent twice-daily use, you’ll notice skin that looks firmer, fuller and more elastic, with fine lines softening and texture looking smoother and more resilient.
The Routine: How to Apply and Layer Correctively
Smooth it over a cleansed face morning and night, then follow with your moisturizer, and finish with SPF in the morning.
- Pairs Well With: Retinoids, peptide moisturizers and SPF 30 or higher
- Conflict Alert: None; it fits into any routine as the serum step right before moisturizer.

IS PETER THOMAS ROTH COLLAGEN SKINJECTION SERUM WORTH IT?
Yes, it’s worth it if you want a serum that plumps and firms while keeping skin beautifully hydrated. Plant-derived exosomes, growth factor and goji stem cells target the look of collagen loss, and collagen, elastin, hyaluronic acid and glycerin add bounce and moisture on top. It’s a great fit for normal, dry and combination skin, especially if fine lines, dullness or a loss of firmness are on your radar. The lightweight, fragrance-free fluid sinks in quickly and layers easily under moisturizer and SPF, so it slips into your routine without fuss. If plump, bouncy-looking skin is your goal, this one is well worth a spot on your shelf.
CAN I USE PETER THOMAS ROTH COLLAGEN SKINJECTION SERUM WITH RETINOL?
Yes, it pairs well with retinol. The formula is built on hydrating, plumping ingredients like hyaluronic acid, glycerin, collagen and peptides, which work on a different track than retinol’s texture-smoothing job. Those humectants keep skin comfortable and well hydrated while your retinol does its work. Smooth this serum over cleansed skin first, then follow with your retinol or moisturizer at night, and finish with SPF in the morning.
