A healthy skin barrier is essential for overall skin health. Whether it’s due to the countless skincare videos on social media or a growing interest in holistic wellness, the skin barrier is once again a hot topic in the beauty world.
Key Points
Maintaining a strong skin barrier supports long-term skin health. In dermatology, this barrier is called the epidermis, and it can be damaged by internal and external factors like poor diet or pollution. Fortunately, with the right products and care, it can be repaired.
What is the skin barrier?
The skin barrier is the outermost layer of skin, known as the stratum corneum, along with its slightly acidic surface and the microbes living there. Dr. Eirini Merika, a consultant dermatologist for Eucerin, explains that skin cells are stacked like bricks, held together by a lipid “mortar” made of ceramides, cholesterol, and fatty acids.
Dr. Mary Sommerlad notes that factors disrupting the skin barrier can be internal, external, or both. Internal factors include genetic skin conditions like eczema and ichthyosis, as well as high stress and illness. External factors involve harsh weather—too much sun, wind, or extreme temperatures—and exposure to chemical irritants such as certain skincare ingredients like AHAs and retinoids. Pollution, smoking, poor sleep, and allergens also play a role.
Dr. Anjali Mahto adds that the most common cause of barrier damage she sees is overusing active ingredients and applying too many products at once, which overwhelms the skin and weakens the barrier.
Signs of a damaged skin barrier
If your skin feels dry, tight, and can’t hold moisture, you may have a compromised barrier, says Dr. Emma Craythorne. It might look ashy or flaky, feel irritated or sting when products are applied, and you could experience acne, rosacea, or eczema. Redness, darkening, and itchiness are also common. Dr. Sommerlad notes that skin texture may become rough and bumpy. People with sensitive skin are more prone to barrier issues and should take extra care to keep it healthy.
Other factors affecting the skin barrier
Dr. David Jack points out that over-exfoliation is a major culprit, often due to excessive skincare use. Even daily habits like washing with very hot water or skipping sunscreen can gradually weaken the barrier. Internal factors such as stress, lack of sleep, hormonal changes, and poor nutrition also reduce barrier resilience. Facialist Sarah Chapman adds that aging slows the skin’s natural production of lipids, ceramides, and hydrators—key components of the barrier.
How to repair your skin barrier
Start by identifying and removing any triggers causing damage. Facialist Katharine Mackenzie Paterson advises simplifying your skincare routine to just a cleanser, moisturizer, and SPF, and cutting out retinoids or acids. Choose a gentle, fragrance-free cleansing milk or cream, stick to this basic routine, and avoid frequently changing products.”It takes weeks to get things under control, and it can actually get worse before it gets better,” explains Dr. Craythorne.
To soothe and hydrate your skin, Dr. Sommerlad suggests using ceramide-rich moisturizers and adding hyaluronic acid to your routine. Dr. Marco Nicoloso, an aesthetic doctor at Ouronyx, recommends looking for barrier-building ingredients such as ceramides, niacinamide, and fatty acids, which help improve dryness and strengthen the skin’s barrier. For reducing inflammation and kickstarting repair, facialist Shane Cooper advises trying red light therapy with an at-home LED mask or a professional treatment, combined with rich skincare formulas to restore moisture.
Be Gentle
It’s important to avoid anything that exfoliates the skin, like rough cloths or scrubs, and stick to lukewarm water to prevent further irritation, says Dr. Mahto. She notes that there’s no quick fix—improvement may take three to four weeks, or up to three months for more long-term damage.
Cut Out Actives
Then, reintroduce them slowly once your skin has healed. Dr. Sommerlad recommends adding one active at a time, such as starting with retinoids before including vitamin C or exfoliators. For chronic barrier issues, choose gentler options like retinaldehyde over retinol, and opt for PHAs instead of AHAs. She also suggests using fluid-based sunscreens, as they require less rubbing than creams.
How to Prevent Further Damage
“A healthy skin barrier is about moderation and balance,” says Mackenzie Paterson. “Avoid past triggers and don’t frequently switch products.” Chapman advises taking a holistic approach, listening to your skin, and introducing new ingredients slowly to allow time for adjustment.
Protection is key: use an antioxidant-rich serum or moisturizer and broad-spectrum SPF every morning to shield your skin from UV rays, pollutants, and environmental stressors. Prioritize sleep, as this is when your skin’s natural repair processes are most active.
Cooper recommends a healthy, balanced diet with plenty of fatty foods like nuts, fruit, and fish, while Chapman suggests taking a daily high-quality omega oil supplement to boost your skin’s resilience and overall health.
