WHAT IS SKIN BARRIER?

Understanding the importance of your skin barrier is essential for you to have a healthy skin.

WHAT IS SKIN BARRIER?
The skin barrier, also known as permeability barrier; moisture barrier; or lipid barrier, is the outermost layer of our skin's surface that consists of cells and lipids (fats). Skin barrier is responsible to make sure moisture does not evaporate from our skin. It also serves as a protective shield against pollution, harmful microorganisms, etc by producing antimicrobial peptides and proteins.
When we take care of our skin barrier, our complexion appears smooth, clear, even-toned and balanced. Hence, it explains if you are experiencing redness, irritation, breakouts, rashes, etc that your skin barrier is damaged.




While our skin barrier does work to protect against
such external assaults, its more important task by
far is to protect us from the terrible threat coming
from the outside.
To further understand, let us use the famous Brick Wall Analogy by Dr. Peter Elias of the University of California. Barrier function refers to the stratum corneum layer of skin (outermost layer of the epidermis) which is analogous to a brick wall. The bricks are the corneocytes (non-living skin cells that are ready to shed). The mortar (cement holding the bricks together) is the intercellular matrix which is composed of lipid bilayers that surround the corneocytes. 

This barrier accomplishes a whole set of critical defensive functions that extend beyond holding body water in and keeping microbes and foreign molecules out. For example, the stratum corneum also blocks the penetration of ultraviolet light, filtering much of it out before it even reaches deeper into the skin, where most of the pigment or ‘melanin granules’ reside. Melanin is in fact only the second line of defense against the penetration of ultraviolet rays.



DAMAGED SKIN BARRIER CAUSES

🗸Aging. Our skin barriers naturally weaken as we age.🗸Emotional Stress.🗸Physical Stress. Fatigue, dehydration, malnourishment, etc.
🗸Environmetal Stress. Sun damage, pollution, climate changes, etc.
🗸Smoking
🗸Over-exfoliation.

HOW TO TAKE CARE OF YOUR SKIN BARRIER

1. Use mild cleansers. Do not use body soap as your facewash as you have a different skin type and texture on your face.
2. Use right moisturizer regularly. Even if you have an oily skin, finding the right moisturizer for your skin type is the key.
3. Apply sunscreen.
4. Drink plenty of water.
5. Do not over exfoliate your skin. Twice a week should be the maximum.

    1. Hello, Selma Vahab
      You should try Klairs Midday Blue Sun Lotion SPF 40/PA +. You can wear it alone or under makeup. It has a great UV protection, an icy blue undertone (which evens out your skin), and a shine-free finish. It is super lightweight and won't make your skin feel oily or sticky. It can also be a primer and a great combo with Klairs Illuminating Supple BB cream. I promise that this one is great as it mattifies your skin and you don't even have to set with a setting powder (both the sunscreen and bb cream).
      You can get them here:
