The skin barrier is the outermost layer of the skin and acts as a protective barrier against environmental stressors. Oral probiotics have been shown to improve skin barrier function, by increasing the production of ceramides, which are lipids that help to maintain the integrity of the skin barrier and increase the production of antimicrobial peptides. Antimicrobial peptides are molecules that help to protect the skin from harmful pathogens. Furthermore, recent studies have also found beneficial effects of probiotics on skin photoaging.
Over-washing can strip the skin of its natural oils and disrupt the skin barrier. Limit washing to once or twice a day and use a gentle, pH-balanced cleanser.
Moisturizing helps to maintain the skin's natural moisture barrier. Look for moisturizers that contain ingredients such as ceramides, hyaluronic acid, and glycerin.
Protect your skin from the sun:
Sun damage can weaken the skin barrier and accelerate aging. Wear protective clothing and use a broad-spectrum sunscreen with SPF 30 or higher.
Avoid harsh skincare products:
Harsh ingredients such as alcohol, fragrances, and sulfates can damage the skin barrier. Look for products that are labeled "fragrance-free" and "sulfate-free."
Drinking enough water helps to keep the skin hydrated and plump.
Stress can weaken the immune system and lead to skin barrier dysfunction. Practice stress-reducing activities such as yoga, meditation, or deep breathing exercises.
