Skin Cancer Awareness Month: Why SPF alone isn't enough to protect your skin this summer
Skin Cancer Awareness Month reminds us that protecting our skin is not just about maintaining a youthful glow but is also about safeguarding our long-term health. Many people only tend to use sunscreen as temperatures rise and when the days are brighter, however it is important to understand that SPF alone is not enough to fully protect your skin from sun damage.
In this blog, award-winning Aesthetic Doctor and skin health specialist, Dr Christine Or explores why a more comprehensive approach to sun protection is essential and how you can truly care for your skin this summer (and all year round).
Understanding what SPF really does
SPF (Sun Protection Factor) measures how well a sunscreen protects against UVB rays, the type which are primarily responsible for causing sunburn and contributing to skin cancer. Many people assume that a high SPF offers complete protection, but unless your sunscreen is labelled "broad-spectrum", you may not be adequately shielded from UVB and UVA damage.
There are two main types of ultraviolet radiation that affects our skin:
UVB rays: which cause sunburn and direct DNA damage
UVA rays: these penetrate deeper into the skin and accelerate ageing as well as can contribute to skin cancer.
Why sunscreen alone can fall short
Even when using a high quality, broad-spectrum SPF, there are several reasons why sunscreen alone isn't enough to adequately protect our skin from harmful UVA and UVB rays:
Application is often inadequate: most people apply less than half the recommended amount of sunscreen which significantly reduces its effectiveness.
Reapplication is often overlooked: SPF should be reapplied every two hours and more frequently if you are swimming or sweating which rarely happens.
Missed areas are common: Ears, lips, eyelids, the scalp and the backs of hands are frequently forgotten and leaving them vulnerable to damage.
no sunscreen blocks all UV rays: Even SPF50 filters around 98% of UVB rays meaning that some exposure still occurs.
A holistic approach to sun protection
To truly protect your skin, it is vital to think beyond sunscreen and take a more layered approach for effective sun protection:
Wear protective clothing such as lightweight, long-sleeved fabrics, hats and UV protective sunglasses which all provide a physical barrier against harmful rays.
Seek shade appropriately and avoid direct sun exposure between 11am and 3pm when UV radiation is at its strongest.
Use antioxidants in your topical skincare such as Vitamin C which can help to neutralise free radicals generated by UV exposure.
Don't forget all year round, daily protection even on cloudy and overcast days as UV rays can still penetrate through these.
Recommended SPF products
Choosing the right sunscreen can make a huge difference not only in protection but also in how consistently you use it. Choose medical-grade formulations that combine effective protection with wearable textures such as:
OBAGI Sun Shield Mineral Broad Spectrum SPF50: A sheer, quick-absorbing formula that provides comprehensive protection against UVA and UVB rays, and defence against infrared and HEV light, which can cause premature skin ageing.
Alumier Sheer Hydration Broad Spectrum SPF30: A hydrating SPF that combines daily moisturisation with reliable sun protection, great for those looking for a lightweight and comfortable SPF for everyday wear.
The best sunscreen is one you will wear consistently, so finding a formula that suits your skin type and lifestyle is key when choosing an SPF.
The role of skin checks and early detection
Sun damage not only increases the risk of skin cancer but also accelerates pigmentation, fine lines and loss of elasticity, but protecting your skin is just part of the equation. Early detection is key when it comes to sun damage, so it is important to regularly examine your skin for new moles or lesions, changes in size, shape or colour, and areas that itch, bleed or don't heal. Do seek advice straight away if you notice anything unusual.
Healthy skin is protected skin
True skin health begins with protection, and by combining SPF with smart sun habits and consistent medical-grade skincare, you are looking after not only your appearance but your health and wellbeing.
