Facial sun cream: when to apply it ?

Applying sunscreen at this precise moment maximizes its effectiveness and guarantees optimum protection from the very first moments of exposure to the sun.

Sun protection doesn’t have to be a last-minute gesture. Incorporating sunscreen into your daily skincare routine is essential to prevent sunburn, premature skin aging and deep-seated damage caused by the sun’s rays.

Regular application, combined with a product with a suitable SPF, protects not only the face, but all exposed areas of the body.

Why is good timing important ?

Timing your sunscreen application is essential to ensure optimum protection against UVA and UVB rays. In fact, sunscreen does not protect immediately: it needs to be applied for around 15 to 30 minutes to fully penetrate and form an effective protective screen on exposed skin. If you apply your sunscreen too late, just before exposure, or worse, after exposure, it renders the protection ineffective, increasing the risk of sunburn and premature skin ageing.

What’s more, sunscreen is an indispensable part of your daily skincare routine. Good timing prevents its application from interfering with other products, such as your serum or moisturizer. By applying your sunscreen as the last step, you ensure that you create a stable protective screen throughout the day, while preserving the effectiveness of the other skincare products you use.

Finally, mastering timing also means being aware of exposure conditions and knowing how to adapt your actions accordingly. For example, whether you’re at the beach, in the mountains, or taking part in a sporting activity, you’ll need to pay particular attention to the amount and renewal of sunscreen you apply. This will enable you to continue protecting your skin effectively in the face of prolonged or intense exposure.

The right order for your morning routine: serum → moisturizer → SPF

Should I wait until after applying my day cream ?

In your morning routine, it’s essential to respect the following order: serum, followed by moisturizer, then sunscreen. Waiting until your day cream is well absorbed before applying sunscreen is important to avoid diluting or compromising the effectiveness of the sunscreen.

This waiting time, generally between 1 and 3 minutes, enables moisturizers to penetrate the skin properly, while ensuring good adhesion and optimal effectiveness of the sun cream applied afterwards.

How do I apply sunscreen to my face ?

For an effective application of sun cream, start by taking a sufficient amount – usually the equivalent of a hazelnut for the face. Apply the cream in small dabs to the key areas: forehead, cheeks, nose and chin. Then gently spread with light, even strokes, taking care to cover all exposed areas, including the neck and ears.

Make sure the sunscreen forms an even, complete film to offer optimum protection against UV rays.

By applying sunscreen last in your skincare routine, you preserve its effectiveness throughout the day. It acts as a real protective shield on the skin’s surface, preventing other products from altering or absorbing it before it reaches its full effect.

How long before exposure should I apply sunscreen ?

To guarantee effective sun protection, it’s advisable to apply your sunscreen face cream around 15 to 30 minutes before exposure to the sun. This allows the cream to penetrate the skin and form a homogeneous protective screen, capable of effectively filtering UVA and UVB rays.

If you apply sunscreen just before going out, you don’t give the protection enough time to set in. This can reduce its effectiveness and increase the risk of sunburn or skin damage.

This rule applies equally to sun creams used as daily care and to those applied during prolonged exposure, whether for the face or body. Make sure you apply the cream generously and evenly, to guarantee complete protection of exposed areas.

Finally, it’s essential to make sunscreen the last step in your morning skincare routine, before make-up if you wear it. This organization ensures optimum effectiveness of your sun protection throughout exposure.

Reapplication: every 2 hours… really ?

It is widely recommended to reapply sunscreen every 2 hours. The aim is to maintain optimum sun protection for the entire duration of exposure. Over time, sunscreen naturally wears off through perspiration, rubbing or even simple evaporation. This reduces its effectiveness. Regular reapplication compensates for this loss, and prevents certain areas of the skin from being left unprotected or covered by layers that are too thin.

However, some studies show that if you apply a sufficient quantity of sunscreen with a high SPF from the outset, the loss of effectiveness may be less, particularly in contexts of moderate exposure such as urban environments or the office. Nevertheless, for prolonged outdoor exposure, especially in direct sunlight, reapplication remains a must, especially after swimming, sweating or wiping your face.

It’s important to note that under-application of sunscreen is frequent, considerably reducing the actual protection offered. To alleviate this problem, we recommend using a product with a higher SPF, and not hesitating to reapply more often than every 2 hours if you’re very exposed to the sun.

Special cases: sport, mountains, pregnancy, post-treatment skin

When playing sports outdoors, it’s essential to step up your sun protection. Intense perspiration and rubbing can rapidly alter the effectiveness of your sunscreen. For optimum protection, choose water- and sweat-resistant sunscreens. And remember to reapply more frequently, even if the recommended duration is generally two hours.

In the mountains,exposure to UV rays is amplified by the high altitude and reflection off the snow. These conditions make the skin particularly vulnerable to sunburn and skin aging. It’s essential to apply a high-protection SPF facial sunscreen before any exposure. Don’t forget to reapply regularly, even on cloudy days, as UV rays often penetrate clouds.

During pregnancy, skin becomes more sensitive and can develop reactions such as melasma, a hormone-related hyperpigmentation. For appropriate protection, opt for a mineral-filter sunscreen, formulated without chemical ingredients that can be absorbed by the body. This solution offers broad-spectrum protection and is perfectly compatible with pregnancy.

To preserve the health of your skin and baby, apply your sunscreen face cream rigorously, and avoid intense sun exposure, especially between 12pm and 4pm.

Finally, after a dermatological treatment such as a peel, dermabrasion or any other treatment that weakens the skin, sun protection becomes a genuine therapeutic gesture. The skin is then particularly sensitive to UV rays and photosensitivity.

The use of an appropriate high SPF protection sunscreen on the face should be systematic and generous. This promotes skin repair and prevents complications or hyperpigmentation.

What you need to know about the application

To effectively protect your skin from sun damage, it’s essential to respect the correct timing of your sunscreen application and to integrate it correctly into your daily routine. Applying your sunscreen around 15 to 30 minutes before exposure and as a last step, after your moisturizer, ensures optimum protection against UVA and UVB rays. Don’t forget to reapply regularly, especially in the event of prolonged exposure.

Finally, adapt your sun care products to your specific activities and needs. Adopt these protective measures today to preserve the health and youthfulness of your skin.
