## Description

COLLAGEN PEPTIDE SERUM - A serum that works to make the skin appear plumper and firmer, to help reduce the appearance of fine lines and wrinkles. POWERFUL INGREDIENTS - Using the Matrxyl 3000 peptide, this smoothing and hydrating collagen serum mimics the effect of what natural collagen would do to your skin, helping it appear plumper and firmer. Syn-Tacks Dual Peptide serum also gives an added boost to aid a reduction in the appearance of fine lines and wrinkles. FOR ALL SKIN TYPES - Suitable for all skin types, even sensitive, it is cruelty-free and fragrance-free. HOW TO USE - Can be used in your AM & PM skincare routine. After cleansing and hydrating with Hyaluronic Acid Serum, gently apply a pea-sized amount of Collagen Peptide Serum and pat into the face and neck and follow with preferred moisturiser. We suggest Bio-Active Ceramide Moisturiser for those wanting to tackle first signs of ageing and support barrier function. Apply SPF as the last step in your AM skincare routine.

Review: Lightweight, Hydrating & Actually Noticeable Results - I’ve been using this collagen peptide serum for a few weeks now, and it’s quickly become part of my daily routine. The texture is very lightweight—almost watery—so it absorbs fast and doesn’t leave any sticky or greasy feeling. That’s a big plus, especially if you layer other skincare or wear makeup. What I noticed most is how hydrated and plump my skin feels after using it consistently. My skin looks smoother, and there’s a subtle glow that wasn’t there before. It hasn’t caused any irritation, which is important for me since I have combination skin. I also like that it works well with other products—I’ve paired it with moisturizers and sunscreen without any pilling. A couple things to keep in mind: results are not overnight, but with consistent use, you do start to see improvement. Also, if you’re expecting dramatic anti-aging effects immediately, this is more of a gradual, skin-supporting product. Overall, it’s a solid, affordable serum that delivers hydration and helps improve skin texture over time. I’d definitely repurchase.
Review: my skin feeling smooth and hydrated - Great serum! Lightweight, absorbs quickly, and leaves my skin feeling smooth and hydrated. I’ve noticed my skin looks healthier and more plump with regular use. Definitely a staple in my routine.

## Questions & Answers

**Q: Does the bottle come with a foil seal under the cap? Both times I ordered this it did not have a seal under the cap.**
A: Mine didn't have a foil seal or that plastic seal usually around the outside of cosmetics.

**Q: In what order is this serum applied if you use other things on your face like Vitamin C, moisturizer and sunscreen (which I use every morning)?**
A: I only use it at night as an alternative to the nights I use Retinol. I use hyaluronic then the peptide then the night moisturizer. I was always told to use the thinner serum first. But I'm not a specialist.

**Q: Whats the ingredients?**
A: KEY INGREDIENTS; 

Matrixyl 3000™ helps to boost collagen production
Syn®-tacks, a dual peptide, that helps provide collagen boosting benefits

### ⭐⭐⭐⭐⭐ my skin feeling smooth and hydrated
*by M***S on January 31, 2026*

Great serum! Lightweight, absorbs quickly, and leaves my skin feeling smooth and hydrated. I’ve noticed my skin looks healthier and more plump with regular use. Definitely a staple in my routine.

### ⭐⭐⭐⭐ Go easy - very oily
*by S***N on June 19, 2024*

This is a powerful product, but if you over-apply it will just sit as an oily residue upon the skin and takes forever to soak in. I pour a thin "line" of product down one index finger, then share/spread it to both index fingers, blot across my face, then finally massage it all in. Good news is that because I use so sparingly it lasts a very long time.
