Sunscreens: The Truth About Absorption and Safety

Do sunscreens actually get absorbed into the blood? Find out how sun protection works and whether sunscreens are safe for your health. Analysis of different types of filters and their effects on the body. Disinformation about sunscreens and absorption into the blood Today we will clear up another myth that sunscreens are bad for your health! There has been a lot of misinformation on social media lately about the dangers of sunscreens. One of the myths that is being repeated is that sunscreens are absorbed into the bloodstream and are dangerous to your health. How do UV filters work in sun protection cosmetics? Cosmetics with UV filters owe their effectiveness to a protective layer on the skin's surface. They act as a shield that is designed to absorb, reflect and disperse UV radiation, protecting the skin from its direct effects. UV radiation can lead to premature skin aging and serious skin and body diseases. Are substances from sunscreen creams absorbed into the blood? The main function of the skin is to act as a barrier against external factors. Substances that penetrate the skin must have the right balance of lipophilic and hydrophilic. The skin has a complex structure, so a given substance must pass through these layers to enter the bloodstream. Chemical sunscreens are lipophilic, but most of them stay in the stratum corneum of the epidermis, not penetrating the bloodstream. Safety and effectiveness of sunscreens New generation organic (chemical) sunscreens are designed to not penetrate the skin easily. FDA studies have shown that only a fraction of a percent of these filters are absorbed. Mineral filters can penetrate the skin, especially if they have small molecules. Orientana combines organic and mineral filters, providing protection and comfort. Cosmetics safety and European standards Cosmetic products, including sunscreens, must undergo strict assessments before being introduced to the market. Sunscreens are subject to European Union restrictions. It is worth investing in proven cosmetics that have been tested and are approved for use in the EU. Summary and recommendations It is worth taking care of the quality of cosmetics that we apply to the skin. Sunscreens are important for protection against UV radiation, and their safety is confirmed by research. Orientana offers cosmetics with UV filters that combine effectiveness and safety, and also guarantee pleasant, easy application and excellent skin care using Asian ingredients of natural origin.

Sunscreens and Vitamin D ☀

Do sunscreens actually block vitamin D synthesis? Learn about the real impact of sunscreens on vitamin D and why supplementation may be necessary. Sunscreens and Vitamin D Synthesis - Truth and Myths Recently, there have been many messages on social media, the authors of which call for the cessation of using SPF, arguing that sunscreens block the synthesis of vitamin D. Have you wondered if this is actually the case? How does vitamin D synthesis in the skin work? Vitamin D is normally synthesized in human skin under the influence of solar radiation, especially UVB radiation. When the sun's rays reach our skin, vitamin D precursors in the skin are converted into the active form of vitamin D3. Balance between sun protection and vitamin D synthesis Creams and lotions with SPF do not block radiation 100%, so some of it always reaches the skin, especially from April to September, when the solar radiation is strong enough and the skin is exposed to the sun. During this period, if we stay outside for long enough, our body can synthesize an adequate amount of vitamin D. After all, we do not cover the entire skin with SPF - usually the feet in sandals, ears or hands are still exposed to the sun. Vitamin D in autumn and winter: is supplementation necessary? In the fall and winter, when solar radiation is weaker and we spend most of our time indoors, our skin is unable to produce enough vitamin D. In such cases, vitamin D supplementation may be necessary regardless of whether or not we use SPF. Dietary Sources of Vitamin D and the Need for Supplementation Eggs, yellow cheeses and oily fish are rich in vitamin D, so vegans must rely solely on supplementation. We encourage you to always consult your doctor or pharmacist before starting a vitamin D supplement to determine the appropriate dose and check for any contraindications to its use. Vitamin D supplementation will increase your levels, but the effects of photoaging and UVB on the skin are really hard to reverse. Repeated exposure to the sun without proper protection can cause serious and irreversible skin damage, so we recommend our natural cosmetics with SPF and consulting a doctor about vitamin D supplementation. Fun fact: As part of the "National Program of Free Vitamin D Testing in Adults", in February 2014, serum 25(OH)D concentration was measured using the DiaSorin Liaison XL system (CLIA method), and basic anthropometric measurements were performed, including calculation of the BMI (Body Mass Index). The study included 2687 adult volunteers (2091 women, 596 men) aged 54.2 ± 16.1 (15.6-89.8) from 10 Polish cities. The results of the study, covering the largest Polish population to date in terms of numbers, are consistent with most current reports, confirming the very large scale of vitamin D deficiency in our country. The state of supply of vitamin D to the adult part of society, at least in the winter months, is unsatisfactory and requires action in the form of supplementation. Trust the sun but check. Sunscreens are important in care.
