The number that changes how you think about this
Up to 30% of skin collagen can be lost in the first five years after oestrogen begins to decline. That's not a gradual, gentle fade — that's a significant structural shift happening in a relatively short window. And once collagen is lost, it's much harder to rebuild than it is to protect and support in the first place.
We don't say this to alarm you. We say it because it reframes how to think about this phase of skincare. The five years around perimenopause and early menopause are genuinely a critical window — not for vanity reasons, but because the structural support your skin needs is changing rapidly and responds well to proactive care.
What collagen actually does
Collagen is a structural protein — it's the scaffolding that gives skin its firmness, bounce, and thickness. Think of it as the mattress springs under the surface. When collagen is abundant, skin looks plump, resilient, and lifted. When it depletes, the surface starts to look slightly deflated — less volume in the cheeks, a little more looseness around the jaw, a general softening of the skin's structure.
Collagen fibres also hold moisture within the skin's deeper layers, which is part of why collagen loss contributes to that deep, structural dehydration that topical products alone can't fully address.
Why oestrogen is so critical to collagen
Oestrogen directly stimulates fibroblasts — the cells responsible for producing collagen. When oestrogen declines, fibroblast activity decreases, collagen production slows, and the existing collagen breaks down faster than it's being replaced. It's a double hit: less being made, more being lost.
UV exposure makes this dramatically worse (sunlight degrades collagen fibres through oxidative stress), which is why daily SPF is part of a collagen protection strategy, not just sun safety.
What actually supports collagen in shifting skin
The most evidence-backed approaches:
- Peptides: Short chains of amino acids that signal fibroblasts to produce more collagen. They essentially speak the skin's biological language to prompt collagen synthesis. Our Peptide Top-Up serum uses 2% Hexapeptide-11 for this.
- Marine bioactives (microplankton): Advanced extracts from marine sources have been shown to deliver a surge of biological energy to skin cells and support the skin's structural architecture. Our Collagen Reboot serum is built around this.
- Bio-retinol: Plant-based alternatives to Vitamin A retinol that stimulate cell renewal and collagen production without the irritation risk. Particularly suited to the more sensitive skin of the shift.
- Daily SPF: Prevents the UV-driven collagen breakdown that counteracts everything else you're doing. Non-negotiable.
It's a long game — and that's fine
Collagen support isn't something you see in a week. It's a 3-6 month strategy, and the results accumulate over time. The skin that's consistently supported looks structurally different 12 months in than skin that isn't — firmer, more volumised, more resilient.
The window matters. But it's not closing — it's just asking for a slightly different approach than what got you here.
