After using this serum for just two weeks, my skin is already feeling softer and more supple! I'm especially impressed with how quickly it worked - no signs of wrinkles or dullness left behind. This product is definitely worth investing in if you're looking for an effective anti-aging solution that delivers visible results. Highly recommended!

After 25, collagen declines roughly 1% per year — and the signs that follow (hollowing, creasing, reduced bounce) are structural, not surface. This serum targets the dermal layer where collagen is synthesised.

  • Palmitoyl Tripeptide-5 signals fibroblasts to increase collagen output
  • Copper Proline Lysine Complex delivers direct amino acid building blocks for collagen
  • Sodium Ascorbyl Phosphate stabilises new collagen against UV and free-radical breakdown

For skin over 40 showing visible loss of firmness, elasticity, or deepening expression lines.

Skin Profile

Wrinkles and sagging map to two distinct problems: loss of collagen density in the dermis (structural) and loss of surface hydration (functional). Palmitoyl Tripeptide-5 addresses the structural layer — it signals fibroblasts to increase collagen synthesis. Copper Proline Lysine Complex provides the amino acid co-factors fibroblasts need to act on that signal. Sodium Ascorbyl Phosphate stabilises new collagen against oxidative degradation. Sodium Hyaluronate resolves the functional layer — holding moisture at the surface while structural repair progresses beneath. Consistent use builds cumulative density; hydration effects are visible sooner.

How to use
  1. Apply to clean, dry face and neck morning and evening.
  2. Dispense 3–4 drops into fingertips. Press gently into skin — do not rub. Work outward from the centre of the face.
  3. Pay particular attention to the eye contour, jaw, and forehead where collagen loss is typically most visible.
  4. Allow 60 seconds to absorb before applying moisturiser. Do not layer over occlusive products first — penetration requires a clear surface.
Key Ingredients

Palmitoyl Tripeptide-5 — A patented lipid-peptide that crosses the dermal barrier and activates fibroblast collagen synthesis. Also relaxes subcutaneous muscle tension contributing to expression-line depth.

Copper Proline Lysine Complex — Combines a trace mineral with two collagen-specific amino acids. Proline and lysine are the structural units collagen fibres are cross-linked from; copper catalyses the enzyme that locks them in place.

Sodium Ascorbyl Phosphate (Vitamin C) — A phosphate-stabilised Vitamin C form that resists oxidation in formulation. Inhibits free-radical chains triggered by UV exposure that degrade newly formed collagen before it matures.

Sodium Hyaluronate (Hyaluronic Acid) — Low-molecular-weight form that reaches the dermal matrix. Holds up to 1,000× its weight in water, maintaining the hydration environment in which collagen fibres organise and integrate.

Onsen Hot Springs Minerals Distillate™ — Sourced from Futamata, Hokkaido. Contains calcium and tourmaline, which support ionic skin-cell communication and the micro-cluster water structure that improves active ingredient delivery across the barrier.

Japan's Hot Springs and the Skin Renewal Connection

Onsen Hot Springs Minerals Distillate™ is sourced from Futamata, Hokkaido — a region with documented therapeutic use since 901 AD. The mineral profile includes calcium and tourmaline alongside Thujopsis dolabrata branch extract, a tree native to Japan used in traditional practice for its calming and restorative properties. These aren't aesthetic additions. Minerals support the cellular environment in which renewal happens — the same principle Japanese physicians applied when prescribing specific springs for specific conditions over a thousand years of recorded practice.

Your questions, answered.

Why does this produce lasting results when other serums wear off?

Most serums hydrate or coat — effects that reverse when you stop. This serum uses Palmitoyl Tripeptide-5, a peptide small enough to reach fibroblasts and precise enough to trigger their collagen-production signal. The fibroblast responds by synthesising new collagen. That structural change does not wash off.

Why no collagen in the formula if it's a collagen serum?

Topical collagen molecules are too large to reach the dermis. More critically, introducing collagen from outside can suppress the skin's own production via negative feedback. This formula uses peptide signals and amino acid co-factors to prompt internal synthesis — the result is collagen the skin made, not collagen applied to it.

How long before I see a visible difference?

Fibroblast response and new collagen organisation take time. Most users report a change in skin feel within 2–3 weeks and visible firmness improvement by week 4–6. Full results reflect continued use — collagen remodelling is cumulative, not immediate. The 60-day guarantee covers the full assessment window.

How long before I see results?

Customers notice visible improvements within 2-3 weeks, with optimal results achieved through consistent use over time.

Is there a risk-free trial?

Absolutely! We want you to feel completely confident in your purchase. That’s why the 60-Day Peptide Collagen Serum comes with a 60-day money-back guarantee. Try it, love it, and if it’s not everything you hoped for, we’ll happily refund your purchase—no questions asked. Your happiness is our priority!

Why Collagen Creams Don't Rebuild Collagen

Collagen is synthesised by fibroblasts in the dermis — roughly 1–2mm beneath the surface. Most collagen serums apply collagen itself, either as a film-forming agent or a hydrating ingredient. Neither reaches the dermis. When collagen is introduced topically, the skin's negative feedback loop reads elevated collagen levels and slows its own production. The deficit compounds quietly while the surface looks temporarily treated. Palmitoyl Tripeptide-5 bypasses this: it is a signalling peptide, not a collagen substitute. It reaches fibroblasts and prompts them to increase output — no feedback suppression, no surface-only effect.

Visible firmness in weeks

I started seeing visible firmness within the typical timeframe mentioned for high-performance lifting complexes, approximately 4 to 8 weeks. It’s excellent for addressing skin sagging and providing multi-layer firming support. My skin looks tighter and healthier overall. This is definitely a product designed to deliver visible improvements in lines and firmness.

More radiant complexion

Beyond the excellent firming benefits, I’ve noticed a significant brightening effect, contributing to a more radiant complexion. This serum offers the anti-aging and brightening double functionality that I needed, helping to make my skin look transparent and healthy. I love the way it enhances my natural radiance.

The ultimate lift!

I was seeking a serum that truly delivered on firming, and this is it. Drawing inspiration from top-tier multi-peptide formulas, this serum feels luxurious and I noticed visible improvements in elasticity and firmness within a few weeks, which is a promise often seen in advanced lifting serums. It smooths out expression lines beautifully, especially around my eye area and forehead. A definite repurchase!

Clean beauty, potent results

I love that this brand emphasizes ethical and environmentally conscious practices, much like other quality skincare lines. It feels like a pure formula, effectively targeting anti-aging concerns like elasticity while avoiding harmful additives. Feeling good about choosing a sustainable product that’s also highly effective makes this my new go-to serum.

Finally, real collagen boosting!

This is the first collagen serum I've used that actually makes my mature skin feel like it's regaining its youthful bounce. It targets aging and elasticity effectively. The difference in the tightness of my skin after four weeks is remarkable. Highly recommend for dull or mature skin types looking for revitalization.

I was tired of heavy, sticky serums. This formula is lightweight and absorbs quickly without leaving any greasy residue. It seamlessly integrates into my routine, whether I use it in the morning before SPF or as a nightly rejuvenation treatment. It’s powerful without any of the drawbacks of heavy formulas.

Smoother, stronger skin

I appreciate that this serum not only addresses aging but also focuses on strengthening my skin barrier, helping the skin become more resilient. My overall skin texture is much smoother, and I've experienced less irritation since incorporating it into my routine. It's truly an investment in achieving smoother, more resilient skin that can withstand the test of time.

Hydration powerhouse!

My skin drinks this in immediately. The hydration boost is incredible, leaving my skin plump and dewy all day, much like the intense moisture promised. It definitely helps those fine lines caused by dehydration simply disappear as my skin drinks in the hydration it craves. It layers perfectly under makeup, which is a major win due to its lightweight formulation

Very nice serum

This does leave your face nice and smooth, have not had it long enough to see a difference, however, the product goes quite a long way. Onsen was good enough to trade this product for another and I appreciate it tremendously and shows the company values its customers. I need more products I imagine to go with this but have cataract surgery coming up so will wait till I am through with both eyes. Maybe with both eyes clear my skin will look younger? Just kidding, at 74 I will try anything once and if it shows an improvement then I buy again or add to what I have. Looking forward to more trials and find out what goes with this serum as I do not know.
