Think of it as a seal, keeping the outermost layers of the skin protected and, subsequently, healthy.
Recently, there has been increasing focus on the skin barrier, and it’s clear why. The skin barrier, formally known as the stratum corneum, is the outermost layer of your skin, playing a vital role in maintaining overall skin health. This barrier functions as a shield, protecting the skin from external aggressors such as pollutants and pathogens while preventing moisture loss.
A healthy skin barrier contributes to a smooth, hydrated complexion and helps prevent issues like dryness, redness, and sensitivity. Conversely, when this barrier is compromised—whether due to environmental stressors, harsh skincare products, or over-exfoliation—it can lead to a range of skin problems.
Recent studies have provided valuable insights into the importance of the skin barrier.
Research published in The Journal of Investigative Dermatology highlights that the skin barrier is crucial in preventing transepidermal water loss (TEWL). When the barrier is damaged, TEWL increases, leading to dehydration and potential irritation.
A study in Dermatology Research and Practice demonstrates that compromised skin barriers are linked to various skin conditions such as eczema and psoriasis. This research emphasizes the need for effective barrier repair to manage and prevent these conditions.
An impaired skin barrier leaves the skin more open to aggressors and irritation, and when we consider that most common skin concerns can be linked right back to inflammation, the correlation between a healthy skin barrier and healthy skin becomes more clear.
Redness, increased skin sensitivity, dry flakey skin and acne breakouts are often signs of a compromised or impaired skin barrier.
Your skin is exposed to triggers and environmental toxins (UV exposure, stress & pollution) that can cause sensitivity and damage to your skin barriers. The one extra step in your routine that can support your skin now and protect it in the long term. Adding food rich in antioxidants and micronutrients or IV therapy into your lifestyle harmful toxins is one way to reduce oxidative stress. Knocking out all the free radicals may protect your skin barrier from these everyday triggers, soothing even the most sensitive skin over time.
When a pimple appears, rather than working to dry it out with intense salicylic acids and astringent products (all of which absolutely do have their right place and right time), Treat your skin in the same way that you would if the skin were flaring up from an irritation, or if it were at its most sensitive (say, after a peel or laser treatment).
Rather than drying it out, change the tact.
My approach, LESS IS MORE! Rebuild the skin barrier, by delivering it with hydrating, nourishing ingredients and keeping the routine minimal. A simple creamy cleanser, a serum, and a moisturizer, all of which are fragrance free.
Strong fragrances in Skincare products have been known to further irritate skin with a compromised barrier.
Avoid products with harsh ingredients that can strip the skin of its natural oils. opt for gentle, pH-balanced cleansers and moisturizers.
Exfoliating too often can disrupt the skin barrier. Stick to a mild exfoliation routine and avoid using abrasive scrubs.
Use sunscreen daily to shield your skin from UV damage, which can impair the barrier function.
To work towards a healthy skin barrier, it’s important to look for products containing really restorative ingredients.
Support and repair the skin barrier, I recommend incorporating specific ingredients into your skincare routine:
These lipids are fundamental to the skin barrier. According to a study in The British Journal of Dermatology, ceramide-based products can significantly improve skin hydration and barrier function by replenishing essential lipids.
Known for its hydrating properties, hyaluronic acid helps maintain moisture levels in the skin. Research in Clinical, Cosmetic and Investigational Dermatology shows that hyaluronic acid can enhance the skin’s ability to retain water and improve barrier function.
This form of vitamin B3 has been shown to strengthen the skin barrier and reduce inflammation. A study in The Journal of Clinical and Aesthetic Dermatology found that niacinamide improves barrier function and reduces the appearance of fine lines and uneven skin tone.
Taking steps to protect and repair it can lead to better, more resilient skin.
In conclusion, maintaining a healthy skin barrier is crucial for achieving and preserving optimal skin health is by finding the root cause, the role of the skin barrier and incorporating barrier-repairing ingredients into your skincare routine, you can enhance your skin's resilience and overall appearance.
