What the Sun Really Does to Your Skin and How to Protect It
We all love the warmth of the sun — those golden rays can boost our mood and even
provide essential vitamin D. But there’s a flip side: prolonged and unprotected sun exposure is one of the leading causes of premature skin ageing and damage.
Whether you're soaking up rays on the beach or just running errands on a cloudy day, your skin is constantly exposed to ultraviolet (UV) radiation.
Here's what the sun really does to your skin — and how you can protect it.
What Happens to Your Skin in the Sun?
Your skin absorbs UV radiation every time you're exposed to sunlight. There are two main types of UV rays that affect your skin:
UVA rays penetrate deeply into the skin and are primarily responsible for premature
ageing (think wrinkles, sagging, and age spots).
UVB rays are more intense and cause sunburns, playing a key role in the development of skin cancer.
How I like to remember these two types is A is for AGEING and B is for BURNING
Together, these rays damage the DNA in skin cells, break down collagen and elastin (the
building blocks of firm, youthful skin), and trigger pigment-producing cells, leading to sunspots and uneven skin tone.
Signs of Sun-Induced Ageing (Photo ageing)
Photo ageing is the term used to describe skin damage caused by the sun. Common signs include:
Wrinkles and fine lines
Loss of elasticity and firmness
Hyperpigmentation (dark spots, melasma)
Dry, leathery texture
Visible blood vessels (spider veins)
A dull or uneven skin tone
These changes can begin as early as your 20s if you're not protecting your skin.
How to Protect Your Skin from Sun Damage
The good news? Sun damage is largely preventable with consistent care. Here’s how to
keep your skin protected and youthful:
1. Use Sunscreen Daily
Our SHEILD SPF 50 is the perfect addition to your skincare routine.
Don’t forget your neck!! One of the thinnest parts of the skin is on the neck, so please protect it!
Apply it every morning, even on cloudy days or when indoors (UVA rays can penetrate windows).
Reapply every 2 hours, especially if sweating or swimming.
2. Wear Protective Clothing
Opt for wide-brimmed hats, sunglasses
3. Seek Shade
Avoid direct sun exposure between 10 AM and 4 PM, when UV rays are strongest.
Use umbrellas or find shaded areas when outside.
4. Avoid Tanning Beds
Tanning beds emit concentrated UV rays that accelerate skin ageing and increase the risk of skin cancer.
5. Use Antioxidants
Incorporate products with vitamin C, E, or niacinamide into your skincare routine. These help combat free radical damage caused by UV rays.
6. Get Regular Skin Checks
Visit a dermatologist annually for a full-body skin exam. Early detection is key to preventing serious skin issues.
Final Thoughts
Sunlight may be a vital part of life, but when it comes to your skin, moderation and
protection are essential. With a few simple habits, you can enjoy the sun safely and keep
your skin healthy, youthful, and glowing for years to come.
Remember: Sunscreen is not just for summer — it’s for every day.
