According to scientists at the University of Manchester, exposure to bright sun destroys the skin microbiome. The risk of developing dermatitis, eczema and psoriasis increases.
Skin microbiome is a collection of microorganisms, including bacteria, fungi and viruses that live on the surface of human skin. Everyone has a unique skin microbiome made up of different types of microorganisms. It plays an important role in maintaining skin health and protecting against pathogens.
Volunteers who were preparing to go on vacation to warm countries were selected to participate in the study, the results of which were published in the journal Frontiers in Aging.
Scientists determined the condition of everyone's skin and assessed the number and composition of actinobacteria, proteobacteria and firmicutes on its surface. The composition of the microbiome was then analyzed several more times.
Participants who spent the longest in the sun had a reduced number of Proteobacteria on the first day after vacation. This is the largest group of bacteria overall.
A reduction in the number and diversity of Proteobacteria is a sign of a disrupted skin microbiome. This can cause the development of acne, dermatitis, eczema and psoriasis.
How to restore the skin microbiome?
1. Avoid harsh skin care products. Use gentle, non-greasy cleansers that do not disrupt the skin's natural barrier or destroy beneficial microorganisms.
2. Use prebiotics and probiotics. Prebiotics are dietary fibers that provide food for beneficial microorganisms, while probiotics are live microorganisms that can be added to cosmetics or taken orally as dietary supplements. They can help restore and maintain a healthy skin microbiome.
3. Proper nutrition. A diet rich in prebiotics and probiotics may promote a healthy skin microbiome. Include vegetables, fruits, whole grains, yogurts in your diet.
4. Avoid excessive hygiene. Frequent washing and use of antiseptics can disrupt the balance of the skin microbiome. Try not to overdo it with the frequency of washing and use gentle products.
5. Reduce stress. Stress can have a negative impact on the skin microbiome. Practice relaxation techniques such as yoga, meditation or deep breathing.
It is important to understand that restoring the skin microbiome is a process that may require time and patience.
