Sun, skin and anti-aging.

Is it possible to sunbathe, take care of your skin and slow down aging? Of course, summer is a season when sun exposure increases considerably, which requires special attention in skin care. The use of sunscreens is essential to prevent ultraviolet (UV) radiation damage, however, many of these products contain chemicals that are potentially harmful to both human health and the environment. In this article, we will explore how to choose a safe and sustainable sunscreen, and discuss the importance of good hydration, an organic and complete diet, supplementation with specific molecules to keep skin young and healthy, and the benefits of the sun for mood and mental health.

Sunscreens: risks and safe alternatives

Dangerous chemicals

Sun, skin and anti-ageing. Many commercially available sunscreens contain chemicals that have been linked to an increased risk of skin cancer. Among the most dangerous are:

• Oxybenzone: This chemical, present in about 70% of sunscreens, can disrupt the endocrine system and has been linked to cell damage that can lead to skin cancer.
• Synthetic fragrances: Often added to enhance the scent of the product, these fragrances can cause skin irritation and allergic reactions.
• Retinyl palmitate (vitamin A): Although known for its antioxidant benefits, its use in sunscreens may increase the skin’s sensitivity to sunlight, increasing the risk of sunburn and skin damage.

Environmental impact

The impact of these chemicals is not only limited to human health. They also pose a significant threat to the environment, especially to marine ecosystems. Oxybenzone, for example, has been documented as a destructive factor for corals and other marine species. It has been shown to kill horseshoe crab eggs and contribute to coral bleaching, putting marine biodiversity at risk.

Safe alternatives

Sun, skin and anti-ageing. For safer and more environmentally friendly sun protection, sunscreens containing zinc oxide or titanium dioxide in their topical form are recommended. These mineral ingredients do not penetrate the skin and do not contain nano-sized particles, making them safe for both humans and marine ecosystems. These sunscreens act by reflecting UV rays, providing a physical barrier against the sun without the risks associated with the aforementioned chemicals.

Choosing a safe sunscreen from the vast range available can be a complex task. Many of these products contain endocrine-disrupting substances, which are especially dangerous for pregnant women, infants and young children. These substances can affect normal growth, induce early puberty and cause problems such as small testicles and low sperm production in boys, as well as increase the risk of cancer. The most dangerous components found in some sunscreens include oxybenzone, synthetic fragrances and retinyl palmitate. For safe sun protection, lotions or creams containing zinc oxide are recommended because of their stability in sunlight and excellent UVA protection. Another good option is titanium dioxide, provided the product:

• Do not contain nanoparticles.
• Offer protection against UVA and UVB rays.

It is important to remember that SPF only offers protection against UVB rays, which enable the production of vitamin D in the skin. UVA rays, on the other hand, are more harmful in terms of causing skin damage and skin cancer. Therefore, avoid sunscreens with an SPF higher than 50. Although a high SPF is not harmful in itself, it can give a false sense of security, causing people to expose themselves to the sun for longer than recommended. In addition, products with a higher SPF often do not provide significantly more protection.

Other tips for safe exposure to the sun

Sun, skin and anti-ageing. Regular exposure to the sun’s rays is highly recommended, and if you can do it every day, all the better. Here are some additional tips for safe sun exposure: 1. Allow your body to produce vitamin D before applying sunscreen. Expose large amounts of your skin (at least 40% of your body) to the sun’s rays for short periods every day. Optimising your vitamin D levels can reduce the risk of many types of cancers and actually reduces the risk of melanoma as well. 2. Stay in the sun long enough for your skin to turn a very light shade of pink. Protect your face from the sun with a safe sunscreen or hat, as facial skin is thinner and more susceptible to damage, such as premature wrinkling. 3. If you must be in the sun for longer periods, cover up with clothing, a hat or shade (either natural or an umbrella). A safe sunscreen can be applied after optimising your daily vitamin D production, although clothing is your best option to avoid sunburn and skin damage.4.Large amounts must be applied to all exposed areas of your skin to be effective. This means that the product must not cause skin allergies and must provide ample protection against UVA and UVB rays. It should also not be absorbed into the skin, as the most effective sunscreen acts as a topical barrier. 5. Consider using an ‘internal sunscreen’ such as astaxanthin for additional sun protection. You will usually need to take daily supplements for several weeks to saturate your body’s tissues enough to provide protection. Astaxanthin can also be applied topically, so it is now used as an ingredient in many sunscreens.

Benefits of sun exposure

It is important to mention that sun exposure also has benefits, one of the most important being vitamin D production. This vitamin is essential for bone and immune system health. In addition, moderate sun exposure can improve mood and mental health. Sunlight stimulates the production of serotonin, a neurotransmitter that helps regulate mood and sleep. Sun exposure can also reduce inflammation and improve conditions such as psoriasis and eczema. https://www.singlecare.com/blog/benefits-of-sunlight/ (Mayo Clinic News Network).

Precautions when exposed to the sun

Although sun exposure has numerous benefits, it is crucial to avoid excesses and take certain precautions:

• Avoid the sun at peak hours: UV radiation is strongest between 12am and 4pm. It is advisable to seek shade during these hours.
• Wear protective clothing: Long-sleeved shirts, trousers, wide-brimmed hats and sunglasses can help protect the skin.
• Apply sunscreen: Use a healthy sunscreen and apply generously every two hours, or more frequently if you are swimming or sweating. (Home) (CDC).

Hydration, nutrition and supplementation for healthy skin

Importance of hydration

Maintaining good hydration is essential for skin health. Water helps maintain the skin’s elasticity and firmness, preventing dryness and the formation of wrinkles. It is recommended to drink at least 8 glasses of water a day and increase your intake during the summer to compensate for fluid loss due to heat and perspiration.

Organic and complete food

A balanced, nutrient-rich diet is key to maintaining healthy skin. Opting for organic foods not only benefits the environment but also our health, as these foods tend to have fewer pesticides and chemicals. Antioxidant-rich foods, such as fruits and vegetables, protect the skin from oxidative damage. Healthy fats, such as those found in avocado and olive oil, help keep skin hydrated and supple.

Supplementation with anti-ageing molecules

Sun, skin and anti-ageing. For deeper skin care, supplementation with specific molecules can be very beneficial. There are products designed to address the underlying processes of skin ageing from the inside out. They contain natural compounds that help maintain skin health at the cellular level.

Key components and benefits of skin supplements:

• Vitamins and micronutrients: Biotin, vitamin E, selenium, copper and zinc ensure a correct nutritional supply, avoiding deficiencies that can deteriorate the skin.
• Powerful antioxidants: Coenzyme Q10, vitamin C, lycopene and isoflavones promote collagen formation, improving skin elasticity.
• Structural compounds: Hyaluronic acid, hydrolysed collagen and chondroitin sulphate maintain the extracellular matrix of the skin, helping to preserve its structure and elasticity.

Photobiomodulation: innovation in skin care

Photobiomodulation (PBM) is a technique that uses red and near-infrared light to promote cell repair and regeneration. This process is based on the absorption of photons by cells, which improves energy production (ATP) and reduces oxidative stress. PBM has been shown to be effective in reducing wrinkles, improving skin elasticity and accelerating wound healing. Incorporating photobiomodulation treatments into your skincare routine can enhance the benefits of other treatments and keep skin looking its best. (Brown University) (Welcome to UCLA Health).
