Using sunscreen every day is essential to keep your skin beautiful, bright and healthy, as well as preventing many problems, such as stains, sagging, premature aging and even skin cancer.

Essential in the daily care routine, sunscreen is responsible for protecting the skin from the sun's rays and keeping it younger and healthier, preventing wrinkles and expression lines. Ultraviolet A rays, popularly known as UVA. They don't make the skin red (UVB rays, also the main cause for skin cancer), but act on the dermis and hypodermis throughout the day when there is light. Even when it's cloudy or raining: they manage to overcome the barrier of the clouds and reach us in these conditions.

By penetrating the deeper layers, UVA leads to the formation of signs of skin aging, such as wrinkles, sagging, stains and dryness.

That’s why we shoulduse sunscreen at other times of the year, including winter and indoors, as visible light, coming from electronic devices, can accelerate skin aging, despite being used by many people only during the summer. It is important to remember that sunscreen shouldnot be used only on the face, but on all exposed areas of the body, such as hands, lap, arms and legs.

The use of the product prevents excessive oiliness, dryness and even skin cancer. In addition, photoprotection delays skin aging and prevents the appearance of spots, sun spots, melasma and sagging.

But how can sunscreen prevent accelerated skin aging?

Unprotected exposure to UVA causes an alteration in the extracellular matrix, formed by structural proteins such as collagen and elastin, responsible for the firmness and elasticity of the skin.

It is an inflammation that causes the degradation of these fibers, the decrease in their production and, in extreme cases, even their destruction.

Not only sunscreen prevents all this damage described above, but it also prolongs the permanence of collagen stored in the body by up to 50% (the one that was produced in the past).

Therefore, the skin staysfirm and smooth for longer thanks to the product's barrier that initially prevents the entry of UVA rays.

Maintaining skin hydration

Sunscreen is not a moisturizer, but it protects the skin barrier that does not let water out of the skin.

One of the characteristics of premature skin aging is dryness, as UVA rays dilate pores and accelerate fluid loss. This unwanted effect can be avoided with the use of sunscreen.  

Minimizing the appearance of stains on the skin

UVA rays that freely enter the skin stimulate melanocytes, the cells that produce melanin (the pigments that make up the skin). The consequence is obvious: appearance ofstains.

The processes of photoaging and photocarcinogenesis [which leads toskin cancer] are usually the result of many years of sun exposure. However, pigmentary changes from premature aging may only be noticed weeks or months after the skin is exposed to the sun without protection.

Longest study on photoprotection claims that daily use ofsunscreen not only prevents, but reverses signs of aging.

A clinical study carried out over a year and published in Dermatologic Surgery - a dermatological publication in the United States, to evaluate the effectiveness of the constant use of sunscreen, points out that the continuous use of a filter throughout the 52 weeks helped to prevent skin damage and to improve the visible signs of photoaging on the skin.

Photoaging is clinically characterized bywrinkles, skin pigmentation issues, changes in skin texture, considered ugly, and can be accompanied by photocarcinogenesis, spots that can become cancerous. Sunscreens play an essential role in preventing these skin anomalies. The study states that, in addition to preventing, sunscreen is able to reverse photodamage.

Using sunscreen can also help to preventacne. The responsible for this extra help in protecting the skin, especially oily, is the salicylic acid present in some protectors. In addition to controlling oiliness, this asset has anti-inflammatory action and prevents contamination by fungi and bacteria. When used on a daily skin care routine, including devices that can help to keep your face clean and acne free, such as theUltrasonic Facial Cleanser, it’s a great combo of products that will help you to maintain your face younger and smooth, protected from the UVA rays.

What’s the correct way to apply sunscreen?

Sunscreen at room temperature lasts a maximum of three to four hours on the skin under normal conditions. “Ideally, there is a new application, if you are doing an intentional exposure

If you have perspired, it is advisable to first dry the sweat and then apply the product. If you get into the water, also choose to dry yourself before and only after using the filter. Here's an important reminder: Look for the appropriate product if immersion in water, always waterproof.

Which sunscreen is better for my skin?

When purchasing the product, it is necessary to pay attention to some topics. First, the sun protection factor. At least 30. And it should protect against ultraviolet radiation A and B. For those with oily skin, it is worth giving preference to gel or spray formulas, not to mention being oil-free so as not to contribute to the formation of acne . If you have normal or dry skin, cream and creamy lotion are ideal.

When choosing the sunscreen, you need to take into account the situations in which you will use the product. For example, going to the beach or club and spending hours in the sun requires a strong sunscreen. When going for long walks, mountaineering or cycling, it is recommended to use a higher SPF. Those who will only travel by car can invest in a formula with factor 30. It filters around 85% of ultraviolet radiation.

Due to advanced technology, there are sunscreens for all skin types and needs, depending on dermatological and even health conditions.
