Sunscreen use

All sunscreens should come with specified instructions on how to use them. For best application, always follow these instructions. The following information is intended as a general guide only for different uses and how to apply sunscreen, but where possible you should always follow instructions on packaging. This can be found in the Drug Facts box.

How to apply sunscreen in 3 simple steps

When applying sunscreen, the most important thing to consider is even skin coverage. Care should be taken to ensure that any exposed skin has a sufficient layer of sunscreen applied. Unprotected skin will be at higher risk of sunburn and further sun induced skin damage. 

Different sunscreens may have different application methods, so be sure to follow the instructions specified on the packaging for correct application of each product. Below is a general guide for how sunscreens should typically be applied: 

  1. Begin by checking the label to see if your sunscreen needs to be shaken prior to application. 

  2. Fully cover all areas of exposed skin and including the often-neglected ears, neck, or backs of hands and knees. Rather than squirting the sunscreen into your hand, apply smaller, evenly sized dots to ensure it spreads thoroughly and effectively. 

  3. When applying it to the face, first spray or squeeze the sunscreen into your hands before gently rubbing it in. This will help to avoid getting any in your eyes or accidental inhalation. 

    When applying sunscreen to your face opt for a face sunscreen, such as the Coppertone Every Tone Invisible Finish Face SPF 55. This caring sunscreen is formulated for the delicate skin on your face and offers broad spectrum SPF 55 protection, while blending in clear on all skin tones. It is suitable for use under makeup, does not clog pores, and is water resistant for up to 40 minutes. 

How much sunscreen should you use?

It’s recommended that you use at least 30ml (about 1.01 oz) of sunscreen - just slightly more than a shot glass – to cover the entire body for an adult. 

You may also be wondering how much sunscreen to use on your face. A good rule of thumb is to use two fingers’ length of sunscreen on the face, and to gently tap it in instead of spreading it.  

Now you know how much sunscreen to apply, you may be wondering when and how often you should apply it. 

How often should you apply sunscreen?

It is advisable to use sun protection every day even if the weather is cloudy. This is why it is good to include SPF in your daily skincare routine. This will get you in the habit of applying a protective layer every day. You can do so by using a moisturizer with SPF or rounding off your routine with a face sunscreen.

How often should you reapply sunscreen?

Always follow the instructions in the Drug Facts Box of the sunscreen’s packaging. Typically, you should reapply at least every two hours, as well as immediately after swimming or after breaking a sweat, since both will lower the SPF of any sunscreen applied beforehand. 

If you plan to exercise or swim outside, consider using a sunscreen formulated to resist water and sweat, such as Coppertone Sport SPF30 Lotion. Designed to stay on when you sweat or are exposed to water (up to 80 minutes), Coppertone Sport Sunscreen Lotion offers broad spectrum UVA/UVB protection that feels lightweight and moisturizes all day. 

When to apply sunscreen

Should you apply sunscreen every day?

You should apply sunscreen every day your skin is exposed to the sun. The sun’s harmful UV rays are always present, so to minimize the risk of skin damage, always apply sunscreen to any exposed areas of the body. 

Applying it to your face is particularly important: “Your face is exposed to the sun every day even if it’s cloudy or cold. Therefore, it needs special, reliable protection against UVA and UVB rays,” explains Beiersdorf’s Dr. Göddertz. 

How long does it take for sunscreen to absorb?

Apply your sunscreen 15 minutes before sun exposure. 

What goes first, sunscreen or moisturizer?

Sunscreen should be applied after moisturizer. “Apply your facial sunscreen after the day care to protect your sensitive facial skin from signs of premature aging like wrinkles or pigment spots.” Advises Beiersdorf’s Dr. Göddertz.

Do you put sunscreen on before or after makeup?

It is recommended to always apply sunscreen before makeup. 

When applying sunscreen before makeup, be sure to let your skin dry for at least 5 minutes beforehand as this will ensure maximum absorption. Products such as the Coppertone Every Tone Invisible Finish Face SPF 55 are ideal to apply underneath makeup due to the lightweight and invisible formula. 

Of course, reapplying sunscreen throughout the day may affect makeup. One way of avoiding this is to dab a makeup sponge in a small pool of sunscreen and dab it over your face. 

By dabbing instead of rubbing, you avoid smudging the makeup. Additionally, using a lighter sunscreen will also help to avoid smudging, but as always, it’s best to opt for the sunscreen that will afford you the most protection. 

Another alternative is tinted sunscreen or makeup containing integrated sun protection, providing the SPF level is sufficient. 

Can you use sunscreen as a moisturizer?

Yes, although it’s best not to use it as a substitute. Moisturizers are purpose made for hydrating skin; sunscreen can as well but this is usually a secondary feature. 

It also depends on whether your sunscreen is formulated for a specific skin type. For example, a sunscreen formulated for oily skin will be lighter, and so you should use a moisturizer too otherwise your skin may not be sufficiently hydrated.

How to apply sunscreen on your own back

The easiest answer for how to apply sunscreen to your back is to have someone else apply it for you. But what do you do in the absence of a helper? 

Unfortunately, there’s no effortless way to do this yourself with a traditional sunscreen, but you could turn to spray on sunscreen to get those harder to reach areas. Coppertone offers a range of mist spray sunscreens that are designed with ease in mind. 

Coppertone Complete SPF 50 Spray with broad spectrum UVA/UVB protection feels lightweight and provides durable and water-resistant protection (up to 80 minutes, always reapply after getting wet). The continuous sprayer can be used from any angle for ease of application. 

Be sure to spray liberally, especially if you can’t inspect your work on a reflective surface! If you’re unsure what’s meant by “apply liberally,” try to imagine the absolute minimum required to cover all areas of exposed skin with a visible layer of sunscreen, and you should have your answer. 

Summary

Proper sunscreen application is vital for effective sun protection, always follow packaging instructions for use. Ensure even coverage on all exposed skin, including neglected areas like ears and neck. Always follow the products instructions in the Drug Facts box and reapply at least every two hours, opt for lightweight formulas under makeup, and consider spray-on options for hard-to-reach areas like the back. Following these steps and other sun safety measures can help minimize the risk of sun-induced skin damage.
