With summer fast approaching in January 2025, it’s time to start considering your sun protection for the warmer months. Choosing the right sunscreen is crucial in shielding our skin from harmful UV rays. In this article, we will explore key elements to consider when choosing your sunscreen, including understanding Sun Protection Factor (SPF), selecting the right SPF according to your phototype, and how to properly apply sunscreen.
Understanding Sun Protection Factor (SPF)
What is SPF ?
SPF, or Sun Protection Factor, measures a sunscreen’s ability to protect the skin from UVB rays – the kind of radiation that causes sunburn. The numbers on a product range from 15 to beyond 50.
Selecting an SPF
Experts recommend using a sunscreen with an SPF of at least 30, especially if you have fair or sensitive skin. While products labelled SPF 50 provide more protection, no sunscreen can block 100% of UV rays.
After understanding what SPFs are and their importance, let’s delve into how to choose the appropriate SPF according to your phototype.
Selecting the Appropriate SPF According to Your Phototype
Different Skin Types
Your skin type significantly affects how you react to sun exposure. There are six different phototypes ranging from very fair (phototype I) to very dark (phototype VI). The lighter the skin, the higher the recommended SPF.
Sunscreen for Sensitive Skin
Individuals with light-colored skin, freckles or numerous moles should be particularly careful and use high-SPF sunscreens.
Now that we have a clearer idea about choosing SPFs according to different skin types, let’s explore the difference between SPF 15, 30 and 50.
Difference between SPF 15, 30 and 50
Level of Protection
An SPF 15 sunscreen blocks about 93% of UVB rays, while an SPF 30 sunscreen blocks nearly 97%, and an SPF 50 blocks approximately 98%. The difference seems small but can be significant for people with high sun sensitivity.
We’ve clarified the differences among various SPFs. Now let’s look into a crucial topic: the protection of children’s delicate skin.
Protecting Children: Which SPF to Choose ?
Sunscreens for Children
Children have sensitive skin that requires special care. Dermatologists recommend using mineral sunscreens with an SPF of at least 30 on children aged six months and older.
Securing the right sunscreen is only half the battle; applying it correctly is equally as important.
How to Properly Apply Sunscreen ?
Amount and Frequency
A generous application is required for maximum protection – about one teaspoon for the face and two tablespoons for the body. Apply your sunscreen at least 30 minutes before sun exposure and reapply every two hours or more frequently if you swim or sweat.
The format in which your sunscreen comes can also make a difference in its effectiveness.
Sunscreen Textures and Formats: What to choose ?
Creams, Lotions, Sprays…
The choice between creams, lotions, sprays and sticks depends on personal preference. However, creams are generally best for dry skin and the face while lotions are easier to apply on large areas.
In summary, protecting your skin this summer starts well before hitting the beach. Arm yourself with the right sunscreen and apply it properly to enjoy the sun’s benefits without running risks.
