Do You Only Need Sunscreen on Sunny Days? Here’s Why That’s a Myth
It’s easy to assume that if the sky is cloudy or you’re indoors most of the day, sunscreen isn’t necessary. But if your goal is long-term skin health — and prevention of early ageing — sunscreen should be part of your daily routine, year-round.
Let’s unpack why.
UV Damage Doesn’t Take a Day Off
Even when it’s overcast, up to 80% of UV rays can still penetrate cloud cover. These rays don’t cause a visible burn, but they can:
Damage collagen and elastin
Trigger pigmentation
Disrupt skin’s natural repair processes
Accelerate signs of ageing like fine lines and sagging
And if you’re near windows, driving, or sitting by a sunny café spot? You’re still getting UVA exposure.
The Difference Between UVA and UVB Rays
UVB rays cause sunburn — they’re strongest in summer and during peak sunlight hours.
UVA rays are present all year and all day. They go deeper into the skin and are the main culprits behind premature ageing.
Standard glass blocks UVB but not UVA — so even if you’re indoors, your skin is still exposed.
Why We Recommend Daily SPF at Platinum Cosmetics
At our Port Melbourne clinic, we see first-hand how sun exposure contributes to pigmentation, volume loss, and uneven texture. That’s why we always recommend:
Broad-spectrum SPF 30+ or higher
Daily use — regardless of weather, season, or location
Reapplication if outdoors for extended periods
