Sunscreen is an essential item for the health and beauty of the skin, especially in summer, when the sun's rays are more intense. But do you know how to choose the best product for your skin type? In this article, we will give you some tips to get things right when purchasing and ensure effective and adequate protection.
First of all, it is important to know that there are two types of sunscreens: physical and chemical. Physical protectors are those that form a barrier on the surface of the skin, reflecting solar radiation. They tend to have a thicker texture and leave a whitish appearance on the skin. Chemical protectors are those that penetrate the skin and absorb radiation, transforming it into heat. They tend to have a lighter texture and do not change the color of the skin.
Physical protectors are best suited for sensitive, allergic or rosacea skin, as they are less likely to cause irritation or an allergic reaction. They are also more resistant to water and sweat, making them ideal for those who practice physical activities outdoors. On the other hand, they can clog pores and encourage the appearance of blackheads and pimples, especially in oily or combination skin.
Chemical protectors are best suited for normal, dry or mature skin, as they have greater hydration power and prevent premature aging. They are also easier to spread and do not leave residue on the skin. However, they can lose their effectiveness over time, making it necessary to reapply more frequently. Furthermore, they can cause burning eyes or skin sensitivity, especially in fair skin or skin prone to redness.
In addition to the type of sunscreen, it is necessary to take into account the sun protection factor (SPF), which indicates the level of protection against UVB rays, responsible for sunburn. The ideal FPS depends on your phototype, that is, the color and sensitivity of your skin to the sun. The lighter your skin, the higher your SPF should be. In general, it is recommended to use an SPF of at least 30 for the face and 15 for the body.

Another important aspect is PPD (Persistent Pigment Darkening), which indicates the level of protection against UVA rays, responsible for tanning and skin aging. The ideal PPD also depends on your phototype, but it should always be at least 1/3 of the FPS. For example, if you use SPF 30, the PPD should be at least 10.
To make choosing a sunscreen easier, you can consult a dermatologist, who will evaluate the characteristics of your skin and recommend the most suitable product for your needs. Furthermore, you can check whether the product has the seal of the Brazilian Society of Dermatology (SBD), which guarantees the quality and safety of sunscreens sold in Brazil.
Remember that sunscreen should be used daily, even on cloudy or rainy days, as the sun's rays penetrate the clouds and can cause damage to the skin. Apply the product about 20 minutes before sun exposure and reapply every two hours or whenever you sweat a lot or enter the water. Also avoid exposing yourself to the sun between 10 am and 4 pm, when the radiation is strongest.
By following these tips, you will be able to enjoy summer with beautiful, healthy and protected skin!
