At Cosmetier, we believe that healthy, vibrant skin isn’t just about what you apply — it’s also about what you protect it from. One of the most overlooked contributors to premature skin ageing is something we all encounter daily: sun exposure.
Whether you’re commuting, walking the dog, or simply sitting by a window, ultraviolet (UV) rays can have a lasting impact on your skin — even when the sun isn’t visibly shining.
Understanding Photoageing
Sun-related skin ageing is known as photoageing, a process that differs from natural, chronological ageing. Photoageing is caused by repeated and unprotected exposure to UV radiation — particularly UVA rays, which penetrate deeper into the skin and are present all year round.
Here’s what repeated sun exposure can do to your skin:
-
Break down collagen and elastin, leading to fine lines and sagging
-
Trigger uneven pigmentation, including sunspots and freckles
-
Contribute to rough, leathery texture
-
Weaken the skin’s barrier function, resulting in dehydration and sensitivity
In fact, research shows that up to 80% of visible facial ageing is due to sun damage — not genetics.
A striking case published in the New England Journal of Medicine illustrated this: a truck driver with extensive sun exposure on one side of his face developed asymmetrical ageing, with one side appearing nearly ten years older due to consistent UVA exposure through his driver’s window.
“But I Only Use Sunscreen on Holiday…”
It’s a common misconception that sunscreen is only necessary in hot weather or on sunny holidays. The truth is, UVA rays are present 365 days a year, and they easily pass through clouds and glass. This means that even on overcast days or during short outdoor errands, your skin is still vulnerable.
Men and women over 40 may begin to notice cumulative effects of sun exposure — from fine lines and dullness to age spots and uneven texture. The good news? It’s never too late to protect your skin and support healthy ageing.
Building a Daily Sun Protection Routine
At Cosmetier, we recommend a few simple, effective steps to reduce the effects of sun exposure and help your skin age more gracefully:
1. Use a broad-spectrum SPF 30 or higher every day
Look for formulations with added antioxidants and mineral filters such as zinc oxide or titanium dioxide. These offer excellent protection and are gentle on sensitive or post-treatment skin. We particularly recommend AlumierMD SPF, available at our Toddington clinic.
2. Reapply during outdoor exposure
Whether you’re enjoying a garden lunch or an afternoon walk, reapplication is key — especially if you’re perspiring or in direct sunlight for long periods.
3. Don’t forget the neck, chest, and hands
These areas often show signs of ageing early but are commonly neglected in skincare routines.
4. Consider tinted SPF
These formulas provide additional defence against visible light and blend easily with most skin tones.
Addressing Existing Skin Damage for Sun Exposure
If you’re already seeing signs of photoageing, there are subtle, effective treatment options available at Cosmetier to help you refresh your appearance without changing how you look:
-
Micro-needling or light chemical peels to gently resurface the skin
-
Skin boosters to restore hydration and glow
These treatments are personalised to your skin’s needs, and always carried out by our experienced team under the guidance of Dr. Sharma.
Final Thoughts: Protection from Sun Exposure is the Simplest Step in Anti-Ageing
