What is SPF and
how often should you apply it?
Sun protection is essential to help you maintain healthy-looking skin and prevent long-term damage. Prolonged exposure to the sun can cause sunburn, premature ageing, and increase the risk of skin damage. Sunscreen plays a crucial role in shielding your skin from harmful UV radiation, and SPF is a key factor in choosing the right protection.
What does
SPF stand for?
The SPF on sunscreen stands for sun protection factor, a relative measurement of how long the sunscreen will protect your skin from ultraviolet (UV) rays. The higher the SPF number, the higher the percentage of UVB rays it will block.
In practice, however, it's a different story, because how long a sun cream stays effective depends on a number of factors, such as how much you apply, the UV index, and whether your skin is sweating or you're swimming. So you should treat the SPF value as a guide and reapply it regularly.
The difference between
SPF levels
- SPF15 blocks approximately 93% of UVB rays
- SPF 30 blocks about 97% of UVB rays
- SPF 50 blocks approximately 98% of UVB rays
SPF is determined by measuring the time it takes for redness (erythema) to appear on unprotected skin exposed to a specific dose of UV rays, compared with unprotected skin. So, in theory, an SPF 30 sun cream would last 30 times longer than the same exposure without protection. In practice, however, it's a different story, because how long a sun cream stays effective depends on a number of factors, such as how much you apply, the UV index, and whether your skin is sweating or you're swimming. So you should treat the SPF value as a guide and reapply it regularly.
How to apply
SPF correctly
You should apply sunscreen generously to all uncovered areas. The amount of SPF needed varies by age:
- Under 3 years: Avoid exposing babies and young children to the sun as much as possible by keeping them in the shade and using protective clothing, a hat, sunglasses and a parasol, as their skin is extremely delicate and more vulnerable to UV damage. For uncovered areas that may get indirect exposure, use at least 5 to 10 ml for babies aged 6 months and over.
- Children (3–5 years): At least 10–15 ml. For more information on choosing the right sun protection for children, check NIVEA's sunscreen guide for children.
- Children (5–10 years): Need at least 15–20 ml for full coverage.
- Adults and children over 10: Need at least 30–40 ml for the whole body.
When you apply SPF on your face, make sure you use a sunscreen formulated for the face and sensitive skin.
How long does SPF 50 last and
how often should you reapply sunscreen?
No matter which SPF level you use, to maintain optimal protection you should reapply sunscreen every two hours. If you are swimming, sweating, or towel-drying, it will wear off more quickly, so you need to reapply more often. Always check the sunscreen's water-resistant label for specific guidance on reapplication during water activities. Regular reapplication helps make sure you stay protected throughout the day.

Protection with SPF
for the face
Your face is highly exposed to UV rays, so daily SPF application is essential to prevent sun damage and premature ageing. SPF 50 provides higher protection, though lower SPFs can work when exposure is less intense if you apply and reapply them correctly.
Apply sunscreen as the last step of your skincare routine and before you apply any makeup, covering your face, neck, and upper torso. Using moisturisers with SPF is a convenient way to build SPF into your routine.
Although many makeup products now contain SPF, they are generally not applied in sufficient quantities to offer adequate protection. So it's still important to make sure you're using enough sunscreen for optimal protection.
For extra convenience, the NIVEA 2in1 Prime UV Serum offers instant SPF 50+ protection and smoothness in a lightweight, fragrance-free formula. Infused with Hyaluron for hydration of the upper layers of the skin and Licochalcone A to boost your skin's natural defence mechanisms (in vitro tested), this serum helps fight premature ageing caused by the sun while keeping your skin healthy-looking. Absorbing quickly without greasiness, it gives you seamless daily sun protection.
Designed for convenience, its premium dispenser makes application effortless. The 2-in-1 action protects and smooths, which makes it perfect for a busy lifestyle. It works well on its own or as a primer under makeup, delivering long-lasting hydration and defence for skin that looks healthy and feels soft.
Protection with SPF
for the body
Choosing the
right SPF for your skin
- Fairer skin tones:
For fair skin tones, an SPF 50+ is recommended, because fair skin has lower melanin levels and is more prone to burning and skin damage.
- Darker skin tones:For darker skin tones, an SPF 30+ is usually sufficient, as melanin offers some natural UV defence. However, this does not remove the risk of sunburn, hyperpigmentation, or skin damage, so daily SPF application is still essential. In some cases, an SPF 50 may be recommended, especially to protect your face when exposure is high or if you have hyperpigmentation.
- Oily skin:For oily skin, it's best to use a lightweight, mattifying sunscreen that will not clog pores or feel greasy. Sun protection products in fluid or gel form generally feel less oily than creams. Look for products with an ultra-light texture and ingredients such as Niacinamide to absorb excess sebum and help prevent imperfections.
- Sensitive skin:For sensitive skin, choose sun creams specially formulated for this skin type and dermatologically tested. Fragrance-free, ethyl alcohol-free options for sensitive skin help reduce the risk of redness and discomfort.
- Dry skin:Dry skin benefits from hydrating sunscreens enriched with ingredients like Hyaluronic Acid, Glycerine, or Ceramides to lock in moisture while providing UV protection. Many SPF-infused moisturisers give you both sun protection and hydration, helping to prevent dryness and flaking caused by prolonged sun.
What's the difference?
Your choice between SPF 30 or 50 mainly depends on your skin type, the UV index and how long you plan to stay out in the sun. Although in theory SPF 50 blocks approximately 98% of UVB rays, compared to about 97% for SPF 30, the actual protection will depend on how much you apply, how long you're exposed and how often you reapply.
Protection levels above SPF 50 only offer a small extra benefit, and no SPF level can give you 100% protection. In most situations, SPF 30 is adequate if you apply it correctly and regularly; however, SPF 50 is still the safer option for fair skin or heavy exposure.
