The risks of overexposure to the sun are on everyone’s lips: burns, signs of premature aging such as sun spots, wrinkles or dermal dehydration… leading us to believe that the Sun is our enemy. Despite this, its light has been fundamental for the development of life and for our health since the beginning of time.

At summecosmetics we want to help you enjoy this summer to the fullest and finally lose your fear of the Sun. Keep reading to discover everything that its rays give us, as well as our advice on how to protect yourself properly… and even enhance its effects!



Vitamin D Synthesis

If you want to keep strong bones and teeth, let the sun help you. Exposure to sunlight, particularly to UVB rays, promotes the synthesis of vitamin D in the skin. This is essential for calcium absorption, in addition to having protective effects against multiple diseases.

Emotional Wellbeing

Have you ever noticed that when the good weather arrives, you are more cheerful and in a good mood? This is largely because exposure to sunlight stimulates serotonin production, a hormone associated with mood elevation and calmness. Regular exposure to natural light can help alleviate symptoms of depression, particularly of seasonal affective disorder (SAD) and other mood disorders.

Cardiovascular Health

There is growing evidence that sunlight exposure contributes to cardiovascular health by helping to regulate blood pressure. Furthermore, the increase in vitamin D that we mentioned above, when it is due to sun exposure and not supplementation, is related to an improvement in total cholesterol levels.

Immune System Support

Sunlight also helps to maintain your health by modulating the immune response, which can help reduce body inflammation, the risk of autoimmune diseases and increase the body’s ability to fight infections.

Sleep Quality Improvement

Did you know that your body has an internal clock that lets you know when to feel awake and when to feel sleepy, without even knowing what time it is? Exposure to natural light helps regulate this circadian clock (from the Latin circa, meaning ‘around’ and dies, meaning ‘day’). This is crucial for overall health and well-being, as it improves the quality and duration of sleep.

Skin Therapy

Ultraviolet (UV) light from the sun may be therapeutic for certain skin conditions due to its anti-inflammatory properties and ability to alter the growth cycle of skin cells. Controlled sun exposure is sometimes prescribed under medical supervision for psoriasis, eczema, jaundice and acne.



Although sun exposure has all these positive effects, we must remember that, as everything good, its excess can be harmful.

Our recommendation? Aside from wearing protective clothing and accessories and avoiding the sun during peak hours, we have multiple reasons to believe that sunscreens are one of the best options for protecting your skin:

  • As they do not represent a physical barrier, they can be used in all types of situations, both indoors and outdoors, in cold or warm weather, in any season of the year and even during activities and sports.
  • They prevent uneven tanning, unlike some types of protective accessories, and can even enhance a beautiful golden color on the skin.
  • They are easy and convenient to use, and come in multiple sizes and practical formats, such as mist or stick.
  • Many sunscreens include extra benefits for skin care, such as the combination of active ingredients, colored microspheres or luminous finishes.

With SUMMESUN, our intelligent photoprotection system, you will find a complete range of sunscreens formulated with highly effective anti-aging active ingredients (DNA Protection) and substances that strengthen the skin’s own repair mechanisms.
