So ScarJo launched a serum that claims vegan collagen can “firm” like the real deal. I rolled my eyes — then tested it for three weeks.
The real reason I paid attention? Most plant-based collagens are straight-up marketing fluff. This one uses a patented mushroom ferment that actually signals your skin to make its own collagen. Not the same thing. But closer than anything else I’ve tried.
💧 **What’s in the bottle**
It’s The Outset Firming Vegan Collagen Serum — $54 for 1 oz. The claim that hooked me: “clinically proven to improve firmness in 4 weeks.” Fine, let’s see.
1. **Mushroom ferment complex** — Not a filler. This is the active that mimics collagen peptides.
2. **Niacinamide** — Calms redness while it works. Smart pairing.
3. **Pea protein** — Adds a bit of surface plumping. Temporary but nice.
👩🔬 **The ingredient reality check**
No animal collagen here. Instead, they use a shiitake mushroom ferment called Fision-X — it triggers fibroblasts to produce collagen. The niacinamide (2%) smooths texture. Squalane keeps it from drying you out. And there’s a touch of ectoin, which protects against pollution damage.
– Shiitake ferment: Tells your cells to make collagen
– Niacinamide: Minimizes pores + evens tone
– Squalane: Hydration without greasiness
– Ectoin: Shields from environmental stress
📊 **Texture test — week one vs. week three**
First pump: watery-gel texture. Absorbs in 8 seconds flat. No stickiness. No pilling under moisturizer. Smells like… nothing. Which I actually prefer.
Week 2-3: I noticed my nasolabial folds looked less like deep trenches and more like gentle creases. Not gone — just softer. The real surprise? My forehead texture got smoother. Didn’t expect that from a firming serum.
💡 *One Thing*: Apply to damp skin — the mushroom ferment penetrates way better. I spritz a mist first, then press this in.
✨ **Did it actually firm?**
Measurably yes — but subtly. My jawline looked a tiny bit sharper by week 3. Pores on my cheeks appeared smaller. The “firming” effect is real, not dramatic. It’s like your skin drank a glass of water and stood up straighter.
✅ **Buy if** you want a clean, science-backed collagen alternative that won’t irritate
⏭️ **Skip if** you need instant, obvious lifting (try a device or retinoid)
💰 **Worth it?** Yes — $54 is fair for an active that actually does something
🧴 **My take**
It works — but not like a facelift. Think of it as a really good preventative serum that gives you a subtle, consistent firming effect over time. I’ll finish the bottle.
⭐ **7.5/10** — Solid, not sensational
🛍️ *Where to Buy*: Sephora or direct from The Outset. Grab the travel size first if you’re skeptical — $22.
