The harms of long-term skin dehydration

Do you know that dehydrated skin can lead to various skin problems such as dullness, flakiness, and premature aging?

Chronic dehydration can lead to more severe skin problems, including eczema and psoriasis. To improve skin hydration, it is essential to maintain a healthy and balanced diet, avoid harsh skin care products, and keep the skin moisturized. However, the skin’s ability to absorb nutrients is limited, and only a small percentage of active ingredients in skincare products can penetrate the skin.

Why is my skin still dehydrated even though I moisturize it every day?

Understanding Skin penetration

While a regular skincare routine can help to some extent, the skin is the body’s largest barrier organ, and only about 0.3% of the active nutrient ingredients can penetrate the skin. Skin penetration is influenced by various factors such as molecule size, solubility, and skin health.

On the other hand, skin penetration pathways are relatively fixed, and include transcellular, appendageal, and intercellular pathways. Understanding the science of skin hydration and skin penetration can help us effectively deliver nutrients to the skin and achieve healthy, glowing skin. In this article, we will explore the various aspects of skin hydration and transdermal delivery.

What factors affect the permeability of the skin?

Skin penetration is influenced by various factors, such as molecule size, solubility, and skin health. For example, smaller molecules and those with a positive charge have a higher chance of penetrating the skin. In contrast, larger molecules and those with a negative charge may have difficulty penetrating the skin. Additionally, the thickness of the stratum corneum, the skin’s outermost layer, affects skin penetration.

How to hydrate the skin effectively and efficiently?

The answer is Transdermal delivery!!!

What is Transdermal delivery？

Transdermal delivery is a popular method in the beauty industry for delivering various active ingredients, such as vitamins, minerals, and other nutrients, to the skin. It can be achieved through passive or active methods. Passive methods involve optimizing the formulation of topical products to enhance skin penetration, such as liposomes and nanoparticles. In contrast, active methods involve temporarily increasing the skin’s permeability through physical or chemical means. Common physical methods include iontophoresis, electroporation, and micro-needling. Chemical methods include the use of chemical enhancers such as Azone and DMSO.

The mainstream transdermal delivery methods in the aesthetic market

1. Transdermal patches: These are adhesive patches that are placed on the skin to deliver active ingredients. The patches can be applied to various parts of the body, such as the face, neck, arms, and legs, and are left on for a specified period of time. Transdermal patches are commonly used for delivering medications, but can also be used for cosmetic purposes.

2. Iontophoresis: This method uses a low-level electrical current to drive active ingredients into the skin. The current creates small channels in the skin, allowing the active ingredients to penetrate deeper into the dermis. Iontophoresis is a safe and painless method, but it requires special equipment and trained professionals to administer it.

3. Electroporation: This method uses short, high-voltage electrical pulses to temporarily disrupt the cell membranes and allow active ingredients to penetrate the skin. Electroporation is an effective method for delivering larger molecules, such as proteins and peptides, that cannot penetrate the skin barrier by other means.

4. Ultrasound: This method uses high-frequency sound waves to create microchannels in the skin, allowing active ingredients to penetrate deeper into the skin. Ultrasound is a non-invasive method that is safe and painless, but it requires specialized equipment and trained professionals to administer it.

5. Laser-assisted transdermal delivery: This method uses lasers to create microchannels in the skin, allowing active ingredients to penetrate deeper into the dermis. Laser-assisted transdermal delivery is a safe and effective method, but it requires specialized equipment and trained professionals to administer it.

6. Microdermabrasion: This method uses a device that sprays tiny crystals on the skin to remove dead skin cells and stimulate collagen production. The device also creates microchannels in the skin, allowing active ingredients to penetrate deeper into the dermis. Microdermabrasion is a popular method for improving skin texture and reducing the appearance of fine lines and wrinkles.

7. Microneedling: This method uses a device that contains small, sterile needles to create tiny punctures in the skin. The punctures create microchannels in the skin, allowing active ingredients to penetrate deeper into the dermis. Microneedling is a popular method for improving skin texture, reducing the appearance of scars and stretch marks, and promoting collagen production.
