According to a report published in the Frontiers of Ageing, researchers have discovered a positive link between the skin microbiome and age, as well as a decrease in microbial diversity with declining skin barrier function. The study, conducted by California-based researchers in collaboration with L’Oreal Research and Innovation, analyzed data from 13 studies involving 650 women.
The research revealed that the types of microbes present on our skin change as we age, contributing to the varying appearance of individuals. The scientists termed this phenomenon ‘apparent age’ and sought to identify the specific microbes associated with signs of aging, such as ‘crow’s feet’ and moisture loss.
The study found a positive association between the skin microbiome and the presence of ‘crow’s feet’ – the fine lines that develop around the eyes. Additionally, a negative correlation was observed between moisture loss and the range of bacteria on the skin. While further research is required to establish causation, these findings lay the groundwork for more in-depth investigations and the development of microbiome-based solutions to support skin health during the aging process.
In light of this new understanding, it is crucial to pay attention to our skin microbiome. Microbiome-friendly skincare has gained popularity, as it plays a vital role in maintaining healthy skin. A balanced microbiome helps protect against environmental aggressors, hydrates the skin, and preserves moisture. It also contributes to maintaining a healthy pH balance, as the skin’s surface and upper layers naturally tend to be acidic, with an average pH of around 4.7. Disruption of the microbiome can lead to infections and skin disorders like atopic dermatitis.
To care for the microbiome, it is advisable to include skincare ingredients that promote balance and avoid harsh cleansers and excessive use of certain active ingredients that may disrupt the skin’s pH balance. Prioritizing skin barrier function and being mindful of the frequency and type of treatments applied to the skin, particularly acids and retinol, are also important.
One recommended product is the Skingredients PreProbiotic Hydrating Cleanser (€29, skingredients.com), which supports the skin’s microbiome while effectively removing dirt, makeup, and pollution. It contains Oligosaccharide, a hydrating and soothing prebiotic that aids in preventing water loss, and Lactobacillus, a dairy-free probiotic that boosts the skin’s natural moisturizing factor. Lactobacillus strains have also shown potential in reducing inflammatory lesions associated with acne, offering added benefits for troubled skin.
It is worth noting that environmental factors like pollution can impact the composition of skin microbes and adversely affect skin quality. Therefore, protecting the skin from external aggressors is crucial. Applying a high-factor, broad-spectrum sunscreen like Avène Very High Protection Fluid for Sensitive Skin SPF50+ (€23.50, boots.ie) can help shield the skin from the harmful effects of sun exposure. Additionally, using antioxidant-rich formulas can guard against the damaging effects of smog and pollution.
While topical skincare is essential, it is also important to nourish the skin from within. Complementing a healthy diet and topical skincare with supplements can enhance overall skin health. The Advanced Nutrition Programme Skin Clear Biome (€73, theskinnerd.com) is a supplement containing different strains of probiotic bacteria that work together to balance the skin.
Research continues to shed light on the intricate relationship between the skin microbiome and aging. As we gain a deeper understanding of this connection, it becomes increasingly evident that maintaining a healthy microbiome is key to supporting skin health and combating the signs of aging. By investing in microbiome-friendly skincare, making appropriate lifestyle choices, and protecting the skin from external aggressors, we can promote a radiant and youthful complexion at any age.
