TEWL (Transepidermal Water Loss) is a critical indicator of skin barrier function, representing the rate at which moisture evaporates from the stratum corneum when the skin fails to retain water effectively. An increase in TEWL leads to dryness, sensitivity, and chronic skin conditions such as atopic dermatitis, eczema, and post-cancer treatment skin dehydration.
OLT® technology focuses on reducing TEWL, maintaining the skin’s natural moisture retention, stabilizing the barrier function, and minimizing the impact of external aggressors.
1. Why Does Increased TEWL Affect Skin Health?
✔ Excessive moisture loss causes dryness – When the skin barrier is damaged, TEWL increases, preventing moisture from staying in the skin for an extended period. This results in dryness, tightness, and flakiness.
✔ Barrier thinning increases sensitivity – Dehydrated skin weakens the barrier structure, making it easier for pollutants and allergens to penetrate, triggering redness and irritation.
✔ Disrupts Natural Moisturizing Factors (NMFs) and lipid balance – When TEWL increases, essential NMFs (such as amino acids and ceramides) are lost, further compromising the skin barrier.
2. How Does OLT® Effectively Reduce TEWL?
Biomimetic Barrier Technology to Regulate Water Loss
OLT® uses a multilayer stratum corneum lipid structure, mimicking the natural lipid arrangement of healthy skin. This reinforces the skin barrier, preventing excessive water evaporation.
✔ Traditional moisturizers use humectants like hyaluronic acid and glycerin to temporarily hydrate the skin, but they do not repair the barrier, leading to rapid moisture loss.
✔ OLT® technology, instead, reconstructs the skin barrier, allowing long-term water retention and effectively reducing TEWL to prevent dryness and sensitivity.
Induces Natural Lipid Production to Strengthen Moisture Retention
Unlike conventional moisturizers that directly supply lipids, OLT® stimulates skin cells to produce ceramides and free fatty acids naturally. These components help lock in moisture without causing excessive oiliness, keeping the skin hydrated and resilient over time.
Stabilizes Skin pH and Supports Microbiome Balance
Frequent pH fluctuations weaken the skin’s microbiome, making it more prone to barrier damage and increased TEWL.
✔ OLT® helps maintain a slightly acidic skin pH, ensuring a balanced microbiome and further reducing TEWL.
3. How Does Reduced TEWL Benefit the Skin?
✔ Increased hydration – With reduced TEWL, moisture stays in the skin longer, improving elasticity and glow.
✔ Reduced redness and sensitivity – A stronger barrier prevents irritants from penetrating, significantly lowering inflammation and stinging sensations.
✔ Ideal for atopic and dry skin – Studies show that atopic dermatitis patients have higher TEWL levels than the general population. OLT® helps restore barrier integrity, significantly reducing TEWL.
4. OLT®’s Clinically Proven TEWL Reduction
Clinical studies show that after 14 days of OLT® use, TEWL decreases by over 50%, proving its long-lasting hydration and barrier repair effects. This technology is not only beneficial for daily skincare but also for conditions like atopic dermatitis, eczema, and post-cancer treatment skin care.
5. Why Is OLT® the Key to Long-Lasting Moisture Retention?
Unlike traditional skincare products that provide only temporary hydration, OLT® restores the skin’s natural ability to retain moisture by repairing the barrier, reducing water evaporation, and ensuring long-term skin health.
✔ Uses multilayer lipid structure technology to reduce TEWL and maintain barrier integrity
✔ Stimulates natural lipid synthesis to improve moisture retention
✔ Stabilizes pH and microbiome to prevent further barrier damage and dehydration
✔ Clinically proven to reduce TEWL by over 50%, significantly improving skin hydration
With this advanced technology, OLT® is not just a hydration solution but a complete skin barrier repair system, helping the skin stay healthy and resilient.
