What, do you think, is the largest organ in the body? The heart, the lungs…

Wrong. The skin is the largest organ in the body! Just as we prioritize caring for vital internal organs, we should also give the utmost care and respect to our biggest organ – the skin.

What is the skin barrier?

Well, to start with, the skin is made up of three main layers: the epidermis, the dermis, and the hypodermis. The epidermis, the outermost layer of the skin, houses the skin barrier. This barrier acts as the first line of defense against external stimuli such as pollution, UV rays, and harsh weather. It also works to prevent unnecessary water loss from the skin. External stimuli can include harsh chemicals, strong ingredients, infections, and bacteria. The skin barrier functions like a knight in shining armor, ready to defend and protect the underlying layers of the skin

How do you know if your skin barrier is damaged?

Physically, a damaged skin barrier can present itself as flaking, redness, stinging, sensitivity, or acne breakouts. The causes of damage can vary. For instance, I have acne-prone skin, and it wasn’t until three years ago that I learned the importance of the skin barrier. Previously, I would aggressively treat my acne flare-ups with topical acids and retinols, which would excessively dry out my skin, leaving my skin barrier impaired and ruined for the following week.

Now that I understand the importance of the skin barrier, I have adopted a different approach to skincare. Instead of immediately resorting to acids and exfoliators, I now treat my acne with mild cleansers, hydrating and repairing moisturizers, and protect my skin from additional external irritants by applying SPF regularly. While my acne may not heal as quickly, I have noticed significant improvements in scarring, redness, and stinging…which in effect, makes the whole healing process shorter.

How do you keep your skin barrier healthy?

* Maintain moisture levels in the skin: Drink enough water and always apply a hydrating moisturizer.

* Don’t overuse active ingredients: Listen to your skin and only use what is necessary. Follow instructions regarding usage frequency and amount.

* Use barrier repairing ingredients: Incorporate ingredients such as Vitamin B3 (Niacinamide), Vitamin B5 (Panthenol), ceramides, Hyaluronic Acid, and squalene into your skincare routine.

* Choose mild cleansers: Alternate between foaming/exfoliating cleansers with gentler, milky/creamy cleansers.

* Apply SPF: Always apply sunscreen before leaving the house, regardless of the weather.

The takeaway from this blog is that without the skin barrier, our skin would be extremely vulnerable and susceptible to many serious concerns and disorders. Understanding its importance and adopting a routine that maximizes its duties, will ensure a healthy functioning skin barrier.
