When it comes to sunscreen products, everyone tends to have a specific formula, such as sprays or creams. Spray sunscreen is often a popular choice for quick sun protection, and it’s common to see people using it to protect their skin at the beach or even during summer outings. Many of us find the aerosol format a more convenient option than thick creams and lotions, as it can cover larger areas of the body and feels lighter on the skin.

In general, while sunscreen sprays are less reliable in terms of adequate coverage if you don’t know how to use them. For this reason, we wanted to find out the biggest mistake people make with aerosol sunscreens.

According to dermatologist Dr. Kelly Aschenbeck, sunscreen sprays must be rubbed in for an even layer of coverage on the skin. If not rubbed in, there may be areas that are unprotected. Irregular coverage not only increases the risk of sunburn but also leaves you vulnerable to sun damage, such as sunspots and even skin cancer. Fortunately, applying spray sunscreen safely and effectively by rubbing it in can prevent these problems.

Many people wonder if you should let spray sunscreen sit on your skin before rubbing it in. However, letting it sit rather than rubbing it in section by section does not necessarily increase absorption or effectiveness. In fact, Dr. Kelly Aschenbeck states that rubbing in spray sunscreen immediately will make it easier to get an even layer of coverage while the product is still being applied.

A 2005 study published in the Journal of the American Academy of Dermatology also found that rubbing in spray sunscreen immediately after application ensures adequate coverage. Additionally, when using a product like this, be sure to apply enough to cover the target area to avoid spots. This also applies to chemical and mineral sunscreens.

Do not assume that you can skip proper application just because chemical spray sunscreen won’t leave white marks. You still need to rub the product in completely as you would with a mineral sunscreen. Speaking of which, if you prefer mineral sunscreens to chemical ones due to ingredients or skin sensitivity, you’ll be happy to know that mineral sunscreen sprays are widely available.

All forms of sunscreen can be ineffective if you don’t apply the product correctly, including spray sunscreens. Be sure to use at least SPF 30, reapply every two hours, and rub on an even layer over all exposed areas.

There are many aerosol sunscreens that claim to have a rub-in formula, but if you don’t rub the product into your skin, this will result in uneven coverage and leave you vulnerable to sun damage. If you are concerned about losing product when aiming for hard-to-reach spots or on windy days, spray your sunscreen directly into the palm of your hand and then apply it to your skin. But if your spray sunscreen is labeled with at least SPF 30, a comparable amount will be as effective as creams and lotions, as long as it is applied evenly and correctly.

Note that applying a mist of sunscreen is not enough to protect you from sun rays and is not comparable to a standard lotion or spray. A setting spray that contains SPF should always be accompanied by a facial lotion underneath or, at the very least, a powder sunscreen on top, if only to maximize protective coverage. However, sunscreen sprays and powder sunscreens do not replace lotion sunscreen for the face and should not be used as a reliable alternative on their own.
