What Is the Skin Barrier?

Your body is shielded from free radicals by your skin barrier. Damage is often brought on by harsh surroundings. Protect it with ceramides, oils, and other substances.

The top layer of your skin is referred to as the skin barrier, which is also frequently referred to as the “moisture barrier” or “acid mantle.”

The three major layers of skin are: the epidermis, which is the outermost layer; the dermis, which is the middle layer and includes collagen and elastin as well as the skin’s nerve and blood supply; and the subcutaneous fat, which acts as a barrier between the skin and the muscle.

There are three different cell types in the epidermis:

Keratinocytes: What you conceive of as “skin” is really made up of keratinocytes. They are sometimes referred to as “bricks,” and natural oils, ceramides, and cholesterol serve as the adhesive that holds them together to form a wall that is mostly impervious.

Melanocytes: Melanin is produced by melanocytes. UV rays are absorbed by epidermal melanin, preventing harm to underlying tissues. The skin’s natural skin tone is also a result of melanin.

Langerhan cells: The skin’s ability to produce an immune response against bacteria, fungus, and viruses is aided by Langerhan cells.

The statum corneum, the epidermis’ topmost layer, is the subject of most discussions on the skin barrier.

What may harm the skin barrier?

Keep the good things in while keeping the bad stuff out are the two main functions of the skin barrier. It guards against physical contaminants and UV radiation from solar exposure within the body. By halting transepidermal water loss, the skin barrier also aids in the body’s ability to retain natural moisture.

Skin loses suppleness and appears dry, flaky, and rough if the epidermis’ outermost layer doesn’t have enough water. Skin that is not properly hydrated also struggles to maintain an adequate skin barrier, making it more susceptible to environmental and external factors damaging it.

Another important factor in achieving moisturized, radiant, smooth complexion is a strong barrier.

Symptoms of a Damaged Skin Barrier

There are several ways in which the skin barrier’s essential functions might be disrupted, including:

  • Eczema with rosacea. A hereditary skin barrier deficiency contributes to the development of these disorders. However, these diseases may worsen if the skin barrier sustains further external harm.
  • recurring skin rashes
  • Skin itch
  • lackluster, dehydrated skin
  • Hyperpigmentation
  • skin maladies
  • delayed healing of a wound

Our favorite products to repair the skin barrier:

1. Bioderma Atoderm Ultra Nourishing Creme

You may include this into your skincare regimen if your skin is somewhat damaged or if you want to stop additional skin damage. Although it takes a few months for your skin to fully recover from this moisturizer, it aids in skin barrier regeneration. However, if it has been significantly destroyed, this one is insufficient. This one will undoubtedly assist in restoring your skin’s smoothness and softness if it feels very dry, stretched, dehydrated, or has fine lines. Although it isn’t quite as effective as Bioderma Atoderm Baume, it is naturally more moisturizing. Additionally, Bioderma Ultra Nourishing Creme is Hypoallergenic, Fragrance, Paraben, and Comedogenic Free.

2. COSRX Snail Mucin Essence

This is not a barrier repair cream, but you may use it in conjunction with other products to quickly restore your skin’s barrier. This may be used on top of any active ingredients, including retinol, tretinoin, AHA, and BHA. 96% of the essence is filtrate from snail secretions. Snail slime promotes skin healing, lessens skin dryness, nourishes, and protects skin while reducing wrinkles and acne scarring. As a result of the presence of hyaluronic acid, copper peptides, fibrinolytic enzymes, vitamin A, vitamin E, iron, manganese, and zinc in snail secretion filtrate. Overall, this light essence restores skin, treats dry areas, maintains skin’s suppleness, stops moisture loss, and gives skin a healthy shine. Additionally, COSRX essence is free of hazardous ingredients including paraben, fragrance, ethanol, surfactant, triethanolamine, and artificial color. It is also cruelty-free.

3. Cerave Healing Ointment

It is strongly advised to use Cerave Healing Ointment if you have injured skin as a result of employing active ingredients like AHA, BHA, retinol, or tretinoin. Hyaluronic acid, panthenol, ceramides, and 46.5% petrolatum are ingredients in this ointment that aid in the healing of cracked, chapped, and too dry skin. It should be used in conjunction with an excellent non-comedogenic moisturizer to properly hydrate and moisten excessively dry or dehydrated skin. It is also a non-comedogenic product. But it shouldn’t be used to skin that is prone to acne or pimples. It should only be used once each week after your skin barrier has repaired. Additionally, there are no lanolin, colors, or fragrances in this restorative ointment. As a result, it won’t irritate your skin..

When the weather is dry, folks with combination skin may also use this. Additionally, this cream is free of alcohol, mineral oil, artificial color, parabens, aroma, and essential oils.
