Sunscreen works by absorbing or reflecting harmful UV (ultraviolet) rays from the sun. Vichy Canada offers a range of sunscreens that use specific ingredients to protect the skin from damage caused by UV radiation. For example, the Capital Soleil Ultra-Light UV Lotion SPF 60 Face Protection has a lightweight texture that's ideal for everyday use and contains broad-spectrum protection to protect against both UVA and UVB rays.

SPF stands for Sun Protection Factor, which measures the amount of UVB protection provided by a sunscreen. Vichy Canada offers a range of sunscreens with different SPF levels, such as the Capital Soleil Sport Ultra-Light Refreshing Lotion SPF 60 Body and Face Protection, which is perfect for outdoor activities and provides high-level protection against UVB rays.

The duration of sunscreen depends on various factors, such as the amount applied, activity level, and sweating. As a general rule, sunscreen should be reapplied every two hours, or immediately after swimming or excessive sweating. Vichy Canada offers a range of sunscreens that are water-resistant, such as the Capital Soleil Bare Skin Feel UV Lotion SPF 60 Body and Face Protection, which provides long-lasting protection.

Sunscreen can prevent sunburn, which is the result of UVB radiation, but it may not completely prevent tanning. Tanning is caused by UVA radiation, which can still penetrate the skin even with sunscreen on. However, using a sunscreen with a high SPF can help minimize the tanning effect. Vichy Canada offers a range of sunscreens with different textures, such as the Capital Soleil Mineral Tinted UV Lotion SPF 60 Face Protection, which has a tinted formula that evens out the skin tone while protecting it from UV radiation.

A general rule of thumb is to apply about a quarter-size amount of sunscreen to the face. However, the amount may vary depending on the size of the face and neck. Vichy Canada offers a range of sunscreens that are suitable for different skin types and needs, such as the Capital Soleil Anti-Shine Dry Touch UV Lotion SPF 60 Face Protection, which is specially formulated for those with oily or combination skin.

Sunscreen should be applied after moisturizer. Moisturizer helps to hydrate the skin and provides a smooth base for the sunscreen to adhere to. Vichy Canada offers a range of sunscreens that are also moisturizing, such as the Capital Soleil Moisturizing UV Cream SPF 60 Body and Face Protection, which provides both sun protection and hydration.
