If you've ever wondered whether you really need to wear SPF every day, you're not alone. It's one of the most common questions we hear at YBC London.
Many people think sunscreen is only necessary when it's hot and sunny, but the truth is that UV exposure happens all year round. Whether you're driving to work, sitting by a window or walking the dog on a cloudy day, your skin is still exposed to ultraviolet rays that contribute to premature ageing.
Making SPF part of your daily skincare routine is one of the simplest and most effective ways to protect your skin's health and maintain the results of any aesthetic treatments.
Why Is SPF So Important?
The sun emits two main types of ultraviolet rays that affect your skin:
UVA Rays
UVA rays penetrate deep into the skin and are responsible for:
-
Premature skin ageing
-
Fine lines and wrinkles
-
Loss of collagen and elastin
-
Hyperpigmentation
-
Reduced skin elasticity
UVA rays are present every day of the year and can pass through clouds and glass, meaning your skin is exposed even when you're indoors near windows or driving.
UVB Rays
UVB rays are strongest during the summer months and are the main cause of sunburn. They also contribute to skin damage and increase the risk of skin cancer.
Both UVA and UVB rays make daily sun protection essential.
Should You Wear SPF Every Day?
In short, yes.
Dermatologists and aesthetic practitioners recommend applying a broad-spectrum sunscreen every morning as the final step in your skincare routine.
Even on overcast days, a significant amount of UV radiation reaches your skin. In the UK, UVA exposure remains consistent throughout the year, making daily protection just as important in winter as it is in summer.
Think of SPF as an investment in your future skin.
What SPF Should You Use?
For everyday use, most professionals recommend:
-
SPF 30 as a minimum
-
SPF 50 for prolonged outdoor exposure
-
Broad-spectrum protection against both UVA and UVB rays
If you're spending extended periods outdoors, remember to reapply every two hours and after swimming or excessive sweating.
Does Makeup With SPF Provide Enough Protection?
Many foundations and tinted moisturisers contain SPF, but they rarely provide enough protection on their own.
To achieve the level of protection stated on the bottle, significantly more product would need to be applied than most people use.
For the best protection, apply a dedicated sunscreen before makeup.
Why SPF Matters After Aesthetic Treatments
If you've invested in treatments to improve your skin, protecting those results is essential.
UV exposure can interfere with healing and contribute to pigmentation following certain procedures.
Depending on your treatment plan, your practitioner may recommend being particularly diligent with SPF after treatments such as:
-
Microneedling
-
Polynucleotide skin boosters
-
Chemical peels
-
CO₂ laser resurfacing
-
Medical-grade skincare programmes
Following your aftercare advice helps support the best possible results.
Common Myths About SPF
"I don't burn, so I don't need sunscreen."
Burning isn't the only sign of UV damage. Even without burning, repeated exposure can gradually break down collagen and contribute to premature ageing.
"It's cloudy, so I can skip SPF."
Cloud cover reduces visible sunlight but doesn't block all UV rays. UVA rays still reach your skin on cloudy days.
"I only need SPF on holiday."
Most of our lifetime UV exposure happens during everyday activities, such as commuting, gardening or walking outside.
Consistency matters more than occasional use.
Additional Ways to Protect Your Skin
Alongside wearing SPF every day, you can help protect your skin by:
-
Wearing sunglasses with UV protection
-
Choosing a wide-brimmed hat when spending time outdoors
-
Seeking shade during peak UV hours
-
Wearing protective clothing where appropriate
-
Supporting your skin with antioxidant-rich skincare, such as vitamin C
A combination of daily protection and healthy skincare habits can make a noticeable difference over time.
Frequently Asked Questions
Is SPF only for summer?
No. UVA rays are present throughout the year, making daily SPF important regardless of the season.
Does SPF stop skin ageing?
No product can completely prevent ageing, but regular sunscreen use is one of the most effective ways to reduce UV-related premature ageing and help preserve collagen.
Can I wear SPF if I have oily or acne-prone skin?
Yes. Many modern sunscreens are lightweight, non-comedogenic and specifically formulated for oily or blemish-prone skin. Choosing the right formula can help protect your skin without feeling heavy or greasy.
