OLT® Provides More Than Short-Term Hydration—It Strengthens and Repairs the Skin Barrier with a Hexagonal and Orthorhombic Multilayer Lipid Structure
A Breakthrough in Skin Barrier Repair Technology
Ortholamellar Technology (OLT®) is a patented skin barrier repair technology developed by Zeitschild, designed specifically for sensitive, dry, and damaged skin. The core concept of this technology is to mimic the natural barrier structure of healthy skin by utilizing a biomimetic hexagonal and orthorhombic multilayer stratum corneum lipid structure. This provides long-lasting protection and repair, restoring the skin to its optimal state.
Unlike traditional moisturizing technologies, OLT® does not merely replenish moisture or form a temporary protective layer. Instead, it fundamentally rebuilds the skin’s intercellular lipid structure, restoring the skin barrier to the stability and resilience of healthy skin. This technology is particularly beneficial for atopic dermatitis, dry skin, eczema, psoriasis, diabetic skin, post-cancer treatment skin repair, and infant skincare.
Why Does the Skin Barrier Need Repair?
The stratum corneum is the first line of defense for the human body, composed of corneocytes and intercellular lipids. It is responsible for preventing moisture loss and shielding the skin from environmental aggressors. However, when the skin barrier is damaged, it can lead to various skin issues, including:
✔ Increased moisture loss, causing dryness and peeling.
✔ Higher permeability to irritants, leading to redness, sensitivity, and inflammation.
✔ Weakened defense against bacteria and pollutants, increasing the risk of infection and inflammatory reactions.
Common causes of skin barrier damage include environmental factors (climate change, pollution), internal factors (genetics, stress), and improper skincare habits (over-cleansing, using emulsifier-based products). OLT® technology was developed specifically to address these concerns, restoring the skin to a healthy and balanced state.
The Five Core Features of OLT® Technology
1️⃣ Precisely Mimics the Lipid Structure of Healthy Skin
OLT® replicates the exact lipid arrangement of healthy skin, forming a biomimetic skin barrier that restores the skin’s natural protective function, rather than just providing temporary hydration.
2️⃣ Multilayer Lipid Structure: Hexagonal + Orthorhombic
A healthy skin barrier contains both hexagonal and orthorhombic structures to ensure optimal flexibility and stability. In atopic dermatitis and dry skin, the lack of orthorhombic structures weakens the barrier. OLT® rebuilds both structures, restoring the skin to a state closer to healthy skin.
3️⃣ Reduces TEWL (Transepidermal Water Loss) and Provides Long-Lasting Hydration
TEWL is a key indicator of skin barrier function. Clinical studies show that after 14 days of using OLT®, TEWL decreases by 50%, while skin hydration increases significantly, providing long-term relief and repair for dry skin.
4️⃣ Free from Emulsifiers, Mineral Oils, and Preservatives for Barrier Stability
Many skincare products contain emulsifiers (e.g., PEG, SLS), which can disrupt the natural lipid structure of the skin, worsening sensitivity over time. OLT® is emulsifier-free, avoiding the “wash-out effect” caused by emulsifiers and ensuring stable barrier repair.
5️⃣ Suitable for All Skin Conditions with Barrier Damage
Whether it’s atopic dermatitis, dry skin, acne-prone skin, post-cancer treatment skin care, or infant skincare, OLT® effectively repairs and protects the skin, reducing sensitivity reactions and enhancing skin resilience.
How Does OLT® Differ from Traditional Moisturizing Technology?
Traditional moisturizing methods mainly rely on humectants (e.g., hyaluronic acid, glycerin) to absorb moisture, or occlusives (e.g., mineral oil, petroleum jelly) to form a temporary protective barrier on the skin’s surface. However, these solutions do not truly repair the skin barrier, and once discontinued, the skin quickly returns to its dry state.
OLT® technology is different—it does not simply provide moisture but instead focuses on “skin barrier reconstruction.” This enhances the skin’s own ability to retain moisture, eliminating the need for external hydration products. This means that OLT® not only provides immediate relief but also ensures long-term improvements in skin health.
Who Can Benefit from OLT®?
Due to its gentle and hypoallergenic nature, OLT® is suitable for all skin types, especially those with damaged or sensitive skin barriers, such as:
✔ Atopic dermatitis (AD) patients – Helps repair the barrier, reducing moisture loss and inflammation.
✔ Dry skin – Effectively replenishes intercellular lipids and restores the skin’s natural hydration process.
✔ Post-cancer treatment skin repair – Minimizes the effects of chemotherapy and radiation on the skin barrier, preventing dryness and redness.
✔ Acne-prone skin – Helps regulate sebum production while maintaining a strong barrier, reducing excessive irritation and inflammation.
✔ Infant skin – Gentle formula, free from harsh ingredients, ideal for the delicate immature skin barrier of babies.
OLT®: More Than Just a Moisturizing Technology
OLT® is not just a hydration technology—it is a complete skin barrier repair system. Through its biomimetic multilayer lipid structure, emulsifier-free stabilization, and long-lasting hydration properties, OLT® provides scientific and effective solutions for various skin conditions, helping the skin regain its strength and stability, just like healthy skin.
Whether your concern is dryness, sensitivity, inflammation, or barrier damage, OLT® is your ideal repair partner, offering the most fundamental solution for long-term skin health.
