How can damaged skin barrier be repaired?

External as well as internal factors challenge your skin barrier, each having a different impact on the health of it. Humidity and dryness may affect the skin as either swelling or dehydration, which causes breaking of its balance. The overstimulation of allergens, irritants, and pollutants results in developing skin inflammation, redness, and damage to the barrier. Excessive exposure to sunlight causes the fibers of collagen molecules to degrade, and that’s when effective aging effects become accelerated. Harsh skin care products also damage the barrier, but so does the emotional stress. Finding out those early signs is vital. From then on, rebuilding the skin barrier can begin before the condition progresses into serious problems like eczema or acne outbreaks.

A healthy and strong skin barrier is a key component of your skin defense system, serving as a natural armor against such environmental stressors, pollutants, and microbes while keeping the moisture inside. Once it gets compromised, it gives rise to a range of disturbing symptoms. Proof of the damage to the skin barrier includes dryness, red patches, tightness, sensitivity to cosmetic products, and in some cases, breakouts or irritation. You may also find your skin to be rough or flaky. These symptoms are common because of dehydration and the lack of protection  from external irritants. 

The skin barrier is made of four crucial layers: physical, chemical, microbiological, and immunological where each of them plays an active role in maintaining the barrier's integrity and function. Their alteration would bring out problems such as atopic dermatitis, in which increased hydration becomes an essential part of treatment. Moisturizers help in restoring balance by improving the moisture content, strengthening the stratum corneum, augmenting the chemical barrier, and shielding it from allergenic substances, which brings the overall recovery and homeostasis of the skin. It is much easier to restore a damaged skin barrier when you know the root cause of the damage, but the steps mentioned below should be helpful in most of the cases.

Simplify Your Skincare Routine.

The skin barrier is compromised by excessive use of products that have active ingredients. On the contrary, a minimalist skin routine is an effective solution for fixing skin barrier, which would usually be focused on hydration and protection, while using gentle cleansers and moisturizers.

Temporarily Stop Exfoliating.

Micro-tears, irritation, and lack of moisture can be a result of over-exfoliation, whether it is physical or chemical, lowering the integrity of the skin barrier. In this state, it is best to stop both physical and chemical exfoliation and focus on treatment with nutrifying and hydrating agents to help facilitate repair and prevent more injury.

Choose a Gentle Cleanser.

The need for soap-free cleansers and therapeutic moisturizers is referenced in their importance towards hydrating the skin, restoring skin barrier, and improving treatment outcomes with corticosteroids. For example, consideration of gentle sulfate-free options enables the skin's protective oils to remain intact and permits restabilization of the skin's natural balance. Hydration is essential, so choose those types of moisturizers containing soothing agents. Sources of hydration include glycerin, hyaluronic acid, and panthenol, all of them being useful for healing skin barrier.

Apply Vegetable Oils to Rebuild the Skin Barrier.

The evidence of benefits of topical plant oils for skin health is based on barrier homeostasis, antioxidant and anti-inflammatory representation, improving wound healing, and antimicrobial and anticancer activity.

Use Emollients and Humectants for Hydration.

Moisturizers and emollients act as connective tissue in the restoration of skin barrier function and alleviate dryness, especially in conditions such as atopic dermatitis and psoriasis. Consideration of individualized moisturizers for specific skin abnormalities, would further enhance treatment efficacy and patient outcomes.

Adapt Your Diet to Support Skin Health.

Diet is another crucial factor that determines the health of the skin barrier. Research indicates that omega-3 fatty acids and antioxidants can also help strengthen the skin's barrier. Each of these steps supports the long-term aspect of skin health by repairing skin barrier damage. However, it is wise to approach it patiently, as recovery might take from one day to a few months, depending on severity of damage. With a simple regimen of the right products, along with the corresponding adjustments in diet, you will have all that it takes to restore the natural protection of the skin and even boost its strength against future stress.
