Sunscreens

…

It’s estimated that up to 80% of premature ageing is caused by the sun,[1] so daily sunscreen protection is essential for maintaining youthful-looking skin. Our advanced sunscreen range only utilises premium chemical sun filters for high performance protection against the harmful and ageing effects of UVA and UVB rays. Our formulas also deliver skin-friendly benefits and a non-greasy finish for effortless daily wear.

Frequently Asked Questions

What's the difference between SPF and sunscreen?

SPF – or Sun Protection Factor – refers to the measurement of how well a product defends your skin against UVB rays, which are responsible for sunburn.

Sunscreen, on the other hand, is the actual skincare product that delivers that protection. Think of SPF as the rating, and sunscreen as the vehicle delivering it. 

At Medik8, our moisturisers such as Advanced Day Ultimate Protect (SPF 50+) and Daily Radiance Vitamin C (SPF 30) are expertly formulated to offer broad-spectrum protection – shielding your skin from both UVA (ageing) and UVB (burning) rays, all while delivering daily hydration and antioxidant support.

What does PA mean in sunscreen?
PA is a rating system that indicates the level of protection a sunscreen offers against UVA rays which are the rays responsible for premature skin ageing. The more plus signs after PA (e.g. PA+, PA++, PA+++), the higher the UVA protection. At Medik8, we prioritise broad-spectrum protection in every SPF formula, helping to shield your skin from both UVA and UVB rays for daily defence against photoageing.
How do I choose the SPF level in sunscreen?
Consider your skin type, how much time you spend outdoors, and any added skin concerns. As a rule, everyone should use a minimum of SPF 30. For fair skin, or if you burn easily, opt for SPF 50 or higher. Those with deeper skin tones still need daily sun protection, and SPF 30 or above is recommended. For everyday wear, SPF 30 offers reliable protection. If you’ll be spending extended time outdoors, especially in strong sun or at high altitudes, SPF 50 or higher is advised.
How much sunscreen should I apply to my face?
For full coverage, use around a 10p-sized amount – roughly ¼ teaspoon – for your face and neck. Don’t forget areas like your ears, eyelids, and hairline. Not using enough product is one of the most common SPF mistakes, so be generous.
How often should I reapply sunscreen?

No matter the SPF number, sunscreen should be reapplied every two hours when exposed to daylight, especially after sweating or swimming. Even with high-performance, photostable formulas like those in the Medik8 SPF range, regular reapplication is key to maintaining protection.

If you wear makeup, try using a clean makeup sponge or blender to gently press sunscreen back onto the skin without disturbing your base. This makes top-ups easier and more seamless throughout the day.

What’s the difference between mineral and chemical sunscreen?
Mineral sunscreens (also known as physical sunscreens) use naturally derived filters like zinc oxide or titanium dioxide to sit on the skin’s surface and reflect UV rays. Chemical sunscreens absorb UV rays and convert them into heat, which is then released from the skin. Both types are effective, it comes down to personal preference and skin type. Medik8 uses advanced sunscreen technologies that blend seamlessly into the skin, with no greasy residue or white cast.
How to tell if a sunscreen is good quality?

A high-quality sunscreen offers broad-spectrum protection against both UVA and UVB rays, uses photostable filters that won’t degrade in sunlight, and feels comfortable on the skin. Look for added skincare benefits too; ingredients like antioxidants (such as vitamin C or blueberry seed oil) help defend against free radical damage, while hydrating agents ensure skin stays smooth and balanced.
