While all dermatologists worldwide agree that UV protection should be used by all people every day and not just during a hot, sunny day to prevent from skin cancer, skin ageing and skin barrier damage; a study by CeraVe shows that only 18% of people are applying daily1.. Forming a habit can seem intimidating, but it is widely believed that starting with a commitment of just 21 days can make building habits more manageable and have a lasting impact. That’s why CeraVe is launching the 21 Day SPF Challenge with the #21DaysofSPF to help you build a lasting, dermatologist-approved habit your skin will thank you for.

Why Join the Challenge?

It’s never too late to start incorporating SPF your daily routine! Sun damage is cumulative, with about 23% of lifetime exposure occurring by age 18, according to the Skin Cancer Foundation4.

Using a product with SPF every day is one of the easiest, yet most important ways to keep skin protected, but it is often overlooked as a regular step in a skincare routine. Protecting skin from UV exposure is important every day, not just during summer months or when spending prolonged periods of time outside in direct sunlight. That’s because sun damage can even happen when you are inside on a sunny day or during cloudy days outdoors. So using a moisturiser with SPF like CeraVe AM Facial Moisturising Lotion can help protect the skin from these daily exposures. To better understand the importance of this daily skincare step, it’s helpful to know what happens to your skin during UV exposure.

What is UV Exposure?

Daily exposure to UV rays can have both short-term and long-term effects on the skin, from sunburn and premature aging to an increased risk of skin cancer. There are two kinds of rays the skin needs protection from: UVA and UVB, often called UV “Aging” and UV “Burning” rays, to help you understand the difference. Both UVA and UVB rays don’t just impact skin on a sunny day, as they can come through clouds. In fact, UV rays can often be stronger on cloudier days so it’s always important to always wear SPF when outside, especially on areas of skin more prone to exposure, like the face, neck, and hands. But rays don’t just come through clouds – UVA rays can also come through glass, so it’s important to make sure you’re wearing SPF if you’re near a window, like while driving or when sitting near a window at work or school. Small changes that are simple to implement every day can help keep skin healthier in the long term.

Sun Damage and the Skin Barrier

Sun exposure harms the skin barrier, which is the outermost protective layer of your skin. A healthy skin barrier helps keep skin hydrated by locking in moisture and blocking out irritants.

A critical component of the skin barrier is ceramides, which are lipids that help keep the skin barrier intact. Ceramides are naturally found in skin but can deplete overtime, with UV exposure increasing the rate of depletion. A clinical study commissioned by L’Oréal and released in the Journal of Drugs in Dermatology3 found that daily sun exposure not only damages skin cells, but also significantly reduces the level of Ceramide 3 in the skin and impairs the quality of essential ceramides 1, 3 and 6-II in the skin barrier2.

All of CeraVe's products are enriched with 3 Essential Ceramides to help provide skin barrier maintenance.

CeraVe AM Facial Moisturising Lotion is a facial moisturiser enriched with broad-spectrum SPF30 or 50. This is also formulated with 3 Essential Ceramides (ceramides 1, 3 and 6-II) and helps protect the skin's natural barrier and provide continuous hydration to the skin for up to 24 hours after application, all while simultaneously providing UVA/UVB protection.

UV Exposure and the Risk of Skin Cancer

In addition to keeping the skin barrier healthy, regular use of a product with SPF can also help decrease the risk of skin cancer. According to the Melanoma Research Alliance3, over 90% of all skin cancer is caused by exposure to ultraviolet radiation from the sun or indoor tanning devices. However, the Skin Cancer Foundation4 found that regular daily use of SPF 15 or higher reduces the risk of developing melanoma by 50%, and people who use SPF 15 or higher daily show 24% less skin aging than those who do not use sunscreen daily.
