Soon will start the beach season. This means that you need to protect your skin from the sun’s rays on vacation.
Oncologist and breast physician of Natalya Petrova denied the most common myths about sunscreens with SPF.
Myth 1. The higher the SPF, the better protection
Reality: the SPF – sun protection factor – not that other, as an indicator of the effectiveness of the protection In the rays.
Protection from UVA rays (sun rays) is marked separately or is under Broad spectrum – broad spectrum protection.
Super-High SPF (> 50) give a false sense of security: no burn (UVB rays are blocked well), and the cumulative effect of UFA will have bad consequences.
Myth 2. Water-resistant creams
Salt water for 40 minutes wash off the cream. If the label specifies a different time. Look for the indication of time, for example: Water resistant 80 minutes.
Myth 3. Substances with anti-inflammatory effect of the composition is good
In fact, the effect of chamomile, aloe, allantoin (reduction of redness, etc.) is maintained for 6 hours.
Myth 4. Physical filters – zinc oxides and titanium – harmful to skin
Reality: the FDA and European regulators checked it out. Nanoparticles do not penetrate the skin.
Pros: have a good balance between protection against two types of UV, but when combined with avobenzone (the best UFA-filter) reduces the efficiency of its protection.
Their disadvantages: the titanium dioxide in 2006 recognized carcinogen. Large doses can be obtained by inhaling sunscreen sprays at regular use.
Myth 5. Chemical filters better and more modern
In fact, many of them adversely affect the endocrine system.
The worst filters:
They are able to penetrate the milk, act as the hormone estrogen, there is also the risk of allergies and disorders of the hormonal system.
