Frequently Asked Questions
Is OLT® suitable for sensitive skin?
Yes! OLT® is free from emulsifiers, preservatives, and fragrances, with a neutral pH to minimize irritation. It helps sensitive skin restore its barrier health, reducing redness and discomfort.
👉 Recommended products: AR Serum (Active Relief) + BR Cream (Barrier Repair) – Strengthens the barrier, reducing dryness and sensitivity.
Is OLT® suitable for atopic dermatitis?
Yes! The core issue of atopic dermatitis is a compromised barrier function, leading to increased TEWL (transepidermal water loss), moisture loss, and further inflammation and itching. OLT® utilizes biomimetic barrier technology to help the skin naturally repair its barrier lipids, reducing TEWL and minimizing allergies and inflammation.
👉 Recommended products: AR Serum (Active Relief) + BR Cream (Barrier Repair) – Strengthens the barrier, reducing dryness and sensitivity.
Do I need to use other skincare products along with OLT®?
Whether to combine OLT® with other skincare products depends on individual needs.
🔹 OLT® provides complete barrier repair and hydration, making it suitable as the core of a daily skincare routine.
🔹 It can be used alongside other hypoallergenic skincare products, such as physical sunscreens or gentle cleansers, to enhance overall skincare effectiveness.
🔹 Avoid using products with irritating ingredients (such as alcohol, artificial fragrances, or strong acids) to prevent interference with barrier repair.
👉 Recommended Combinations:
✔ Cleansing: Use a mild, soap-free cleanser like CF Cleaning Foam.
✔ Sun Protection: Physical sunscreens are recommended to avoid irritation from chemical UV filters.
✔ Targeted Treatments: For acne, pigmentation, or anti-aging care, choose hypoallergenic products that do not disrupt barrier repair, and ensure proper layering in your routine.
With OLT® products, you can create a personalized skincare regimen that supports optimal skin protection and recovery.
Is OLT® suitable for post-procedure care (laser, microneedling, chemical peels)?
Yes! After treatments such as laser, microneedling, and chemical peels, the skin barrier is temporarily compromised, making it more prone to redness, dryness, and sensitivity. OLT® effectively supports barrier repair, reduces post-procedure TEWL (transepidermal water loss), minimizes sensitivity and irritation, and accelerates skin recovery.
👉 Recommended products: AR Serum (Active Relief) + BR Cream (Barrier Repair) – Quickly soothes post-procedure sensitivity and enhances the healing process.
Can Rosacea-Prone Skin Use OLT®?
Yes! OLT® is specifically designed for sensitive and barrier-compromised skin, making it suitable for rosacea-prone skin.
🔹 Free from emulsifiers, fragrances, and preservatives, ensuring a gentle, non-irritating formula that won’t worsen redness or sensitivity.
🔹 Strengthens the skin barrier and reduces TEWL (transepidermal water loss), minimizing external irritants’ impact on the skin.
🔹 Soothes redness and sensitivity, stabilizing skin condition and reducing flare-ups caused by barrier damage.
👉 Recommended Products:
✔ AR Serum – Soothes redness and strengthens the barrier
✔ BR Cream – Provides long-lasting hydration and reduces dryness and irritation
Using OLT® products can help rosacea-prone skin remain stable, minimize external irritation, and restore skin to a healthier state.
Is OLT® suitable for oily or acne-prone skin?
Yes! Many issues with oily and acne-prone skin stem from a compromised skin barrier, leading to an imbalance of oil and moisture, which triggers excessive sebum production. OLT® helps restore the skin’s barrier function, rebalancing oil and moisture while reducing external irritation. It does not cause excessive hydration or clog pores.
👉 Recommended product: AC Clear (Soothing Anti-Acne Serum) – Regulates sebum and minimizes external irritation.
Why is some acne-prone skin both oily and dry?
This is a classic sign of oil-water imbalance. When the skin barrier is compromised, moisture cannot be retained, leading to dryness. To compensate for this dryness, the skin produces excess oil, resulting in an “oily on the surface, dry underneath” condition, which can even worsen acne.
🔹 Solution:
Strengthen the skin barrier, restore oil-water balance, and allow the skin to regulate sebum production naturally.
👉 Recommended product: AC Clear (Soothing Anti-Acne Serum) – Supports barrier repair and improves oil-water balance.
Why does OLT® not contain emulsifiers?
Traditional emulsifiers allow water and oil to mix, but they may disrupt the arrangement of skin barrier lipids. Long-term use can weaken the barrier instead of strengthening it. OLT® utilizes an emulsifier-free technology to preserve the integrity of the skin barrier, ensuring that the natural lipid structure remains unaffected and allowing the skin to restore its health naturally.
Who is OLT® suitable for?
Atopic dermatitis, eczema, and sensitive skin
Post-procedure recovery (laser, chemical peels, microneedling, etc.)
Chronically dry and barrier-damaged skin
Skin care after cancer treatments
Oily and acne-prone skin for barrier regulation
What are the steps for using OLT® products?
1️⃣ Cleansing – Use a gentle, non-irritating cleanser, such as CF Cleaning foam.
2️⃣ Soothing & Repair – If the skin is sensitive or in post-procedure recovery, apply AR Serum to stabilize the skin.
3️⃣ Barrier Repair & Hydration – Depending on your needs, use BR Cream or AC Clear for barrier repair and long-lasting hydration.
How long does it take to see results after using OLT® products?
Clinical studies show that after 14 days of using OLT®, TEWL (transepidermal water loss) can be reduced by over 50%, skin hydration significantly increases, and barrier function stabilizes. Most users notice improved moisture levels, reduced redness, and decreased sensitivity within 1-2 weeks.
Is OLT® suitable for infants and young children?
Yes! OLT® is free from fragrances, preservatives, and emulsifiers, with a neutral pH. It is gentle, hypoallergenic, and ideal for infants and young children, especially for conditions like eczema, diaper rash, and dry skin.
👉 Recommended product: BR Cream (Barrier Repair) – Hypoallergenic repair, suitable for infants and sensitive skin.
Which product should I use for dry, peeling skin in winter?
During winter, lower temperatures and humidity accelerate moisture loss (increased TEWL), weakening the skin barrier and reducing its ability to retain moisture. Factors such as indoor heating, long hot showers, and cold winds can further dry out the skin, causing peeling and itching.
🔹 Solution: OLT® utilizes multilayer stratum corneum lipid structure technology to help the skin repair its barrier naturally, reducing TEWL and enhancing moisture retention.
👉 Recommended product: BR Cream (Barrier Repair) – Long-lasting repair to reduce dryness and peeling.
What is Winter Itch, and how can I relieve it?
Winter Itch is caused by cold, dry environments that dehydrate the skin, leading to tightness, itching, redness, and cracking. It commonly occurs on the lower legs, elbows, and back, especially in individuals with dry skin or older adults.
🔹 Solution:
Moisture retention: Use emulsifier-free, hypoallergenic, and high-barrier repair moisturizers.
Reduce irritation: Avoid long hot showers and use gentle cleansing products.
👉 Recommended products: BR Cream (Barrier Repair), AR Serum (Active Relief) – Deep repair to soothe dryness and itching.
Is OLT® suitable for oily or acne-prone skin? Will it be too moisturizing?
Yes! Many issues with oily and acne-prone skin stem from a compromised skin barrier, leading to an imbalance of oil and moisture, which triggers excessive sebum production. OLT® helps restore the skin’s barrier function, rebalancing oil and moisture while reducing external irritation. It does not cause excessive hydration or clog pores.
👉 Recommended product: AC Clear – Regulates sebum and minimizes external irritation.
