What is high sun protection and why is it essential?
High sun protection refers to skin care products that offer a high protection factor (SPF) against the sun's ultraviolet rays. These products are essential for protecting the skin against long-term damage such as sunburn, premature aging and increased risk of skin cancer. Using a sunscreen with an SPF of 30 or higher is strongly recommended for effective protection, especially during prolonged exposure to the sun.
How does high-protection sunscreen work?
High-protection sunscreens contain components that act either by absorbing or reflecting UV rays. Modern formulations incorporate mineral filters such as zinc oxide or titanium dioxide, as well as chemical filters, which together offer a robust barrier against UVA and UVB, the two types of harmful ultraviolet rays.
What are the criteria for choosing a good high sun protection product?
The choice of a good sunscreen should be based on several criteria:
How and when to apply a high-protection sunscreen?
Sunscreen should be applied generously and evenly to all exposed parts of the body, including the face, ears, hands and feet. It's crucial to apply sunscreen 30 minutes before sun exposure to allow the formula to activate properly. Reapply every two hours, or immediately after swimming or sweating heavily.
What are the common mistakes to avoid with high-protection sunscreens?
Common mistakes include:
Is high sun protection suitable for all skin types?
Yes, there are formulations to suit every skin type. For sensitive or acne-prone skin, it's best to choose non-comedogenic and hypoallergenic products to avoid irritation or rashes. Specific sunscreens are also available for babies and children, offering effective protection while being gentle on the skin.
Can high sun protection be combined with other skin care products?
High sun protection can be combined with other skin care products. We recommend applying your usual skincare products first, such as serums and moisturizers, then applying sunscreen as the last step in your morning routine. This ensures that the sunscreen forms an effective barrier against UV rays without being diluted or affected by other products.
Can high-protection sunscreens cause allergic reactions?
Although rare, allergic reactions to sunscreens are not unknown. They are generally caused by certain ingredients present in the chemical filters. For people with sensitive skin, it is advisable to opt for sunscreens containing mineral filters, such as zinc oxide or titanium dioxide, which are better tolerated and less likely to cause allergic reactions.
What's the difference between broad-spectrum and non-broad-spectrum sunscreens?
Broad-spectrum sunscreens are designed to protect against both types of harmful ultraviolet rays: UVA and UVB. UVA rays are primarily responsible for skin aging and can penetrate deeper into the skin, while UVB rays are the main cause of sunburn. Sunscreens that are not broad-spectrum may only protect against UVB, leaving the skin vulnerable to the deeper damage caused by UVA.
How do I know if a high-protection sunscreen is effective?
To assess a sunscreen's effectiveness, check the SPF (sun protection factor), which measures its ability to protect against UVB rays, as well as the "broad spectrum" label for UVA protection. An SPF of 30 or more is generally recommended for good protection. It is also important to look for validations or recommendations by dermatologists or recognized health organizations.
Is high sun protection necessary all year round?
Yes, the use of a high-protection sunscreen is recommended all year round. UVA rays, in particular, are present with the same intensity in all seasons, and can penetrate clouds and glass. Daily protection can therefore help prevent premature skin aging and other long-term skin damage. This is particularly important in environments where exposure to UV rays is high, even during the winter months or on cloudy days.
