Summer is great for a lot of things. Your skin, a little less so.
More time outdoors means more UV exposure, and UV doesn't just sit on the surface. It gets to work on the structure of your skin in ways that SPF alone can't fully address. Here's what's actually happening beneath the surface, and what makes a genuine difference.
What UV does to your skin
Your skin is largely held together by collagen - the protein responsible for keeping it firm, smooth and hydrated. It naturally declines from your mid-twenties, but UV exposure accelerates that process considerably.
When UV radiation hits the skin, it triggers the production of enzymes called matrix metalloproteinases (MMPs). These enzymes break down collagen in the skin's extracellular matrix, while simultaneously suppressing the synthesis of new collagen. The result is a double hit: existing collagen is degraded faster, and the skin's ability to replace it is reduced at the same time(1).
It doesn't stop there. UV exposure also disrupts the skin barrier, increasing transepidermal water loss - the rate at which moisture escapes through the skin's surface. Less collagen plus more moisture loss is why skin can feel drier and look more lined after a summer of sun, even with a good SPF routine(2).
Where SPF stops (and where collagen starts)
You probably have heard in the past that SPF is non-negotiable. It reduces the UV load hitting your skin in the first place, and no supplement replaces it.
But SPF works at the surface. The collagen breakdown it doesn't prevent - the structural damage accumulating in your dermis over weeks of sun exposure, it needs to be addressed from within.
That's where collagen support comes in. Not as a replacement for suncare, but as the part of the picture that topical products simply can't reach.
What to skip
A crowded skincare shelf isn't the answer. Overcleansing, switching products constantly, or layering too many active ingredients can compromise the skin barrier - which is already under more pressure in summer.
The skin barrier is your first line of defence against moisture loss; undermining it with a complicated regime during peak UV season works against you.
Simple, consistent and gentle is a better approach. A good SPF, basic hydration, and support from within.
What to take
Complete Collagen is powered by VeCollal® - the world's first plant-based biomimetic alternative to human Type I collagen.
The clinical data behind it is robust:
In a peer-reviewed double-blind, placebo-controlled trial, eight weeks of daily VeCollal® supplementation produced:
- 32.9% reduction in wrinkle depth
- 7.7% increase in skin collagen density
- 13.1% improvement in skin texture
- 6% increase in skin elasticity
A subsequent independent clinical trial, conducted by the Department of Drug Sciences at the University of Pavia, found further measurable results after eight weeks - including a +21% improvement in skin hydration, measured using a Corneometer, and a +10.5% increase in dermal collagen signal, measured via DermaLab ultrasound.
It indicates the body is actively rebuilding collagen in the dermis, not just receiving it topically.
Summer is when your skin needs more, not less
The natural decline of collagen is something that happens regardless of the season. But UV exposure in summer speeds up that process - which makes consistent collagen support more relevant from June onwards, not less.
Eight weeks of daily Complete Collagen takes you from the start of summer to the end of it, with clinically measurable results.
Start now and your skin is working harder to maintain itself all the way through.
