We know the importance of sunscreen and other skin care products. But there are times when we skip them because we don’t have the time to follow an elaborate ritual or we are just too lazy. Then there is make-up, which we might forget to remove before going off to sleep. Basically, our skin takes a hit when we don’t pay attention to it. Soon, we start experiencing issues with skin. That’s probably because the skin barrier is damaged. Read on to find out the purpose of skin barrier and what to do to repair it if it gets damaged.

The skin barrier, often referred to as the “epidermal barrier,” is the outermost layer of our skin. It consists of specialised cells, lipids and proteins that join forces to protect the body from external elements such as pollutants, pathogens, and UV radiation, explains Dr Sameer Apte, Consultant – Dermatology, SRV Hospitals – Dombivli, Maharashtra. The primary purpose of the skin barrier is to safeguard the body against external threats. It acts as a shield, preventing harmful microorganisms and allergens from entering the body. Also, the skin barrier plays a vital role in maintaining proper hydration, regulating temperature and preventing excessive water loss.

Factors that may damage skin barrier

Various factors, including external and internal, can compromise the integrity of the skin barrier.

Some of them are –

The expert says underlying skin conditions like eczema or psoriasis can also weaken the skin barrier.

Ways to repair damaged skin barrier

Repairing damaged skin barrier is all about paying attention to your skin. Here’s what to do –

1. Gentle cleansing

When you experience skin irritation, you don’t want it to come in contact with any product. Instead of using harsh cleansers loaded with chemicals, use mild, fragrance-free cleansers to avoid further irritation.

2. Moisturise

One of the ways to keep the skin barrier healthy is to apply a rich moisturiser to lock in moisture and promote healing, suggests Dr Apte. Use products that have fatty acids, ceramides and lipids, which make up a big chunk of the skin barrier.

3. Don’t ignore pH

Potential of hydrogen of pH indicates how acidic your skin is. If your skin’s pH is higher or lower than 5.5, it can damage your skin barrier. So, look for skin care products that list their pH.

4. Avoid harsh products

Steer clear of skin care products that contain alcohol, fragrances or strong acids that can lead to dryness or irritation.
