Scientific Principles of ECT1 Sunscreen

ECT1 sunscreen incorporates the extremolyte Ectoin
A cyclic amino acid derivative that protects organisms in extreme environments. It synergizes with the sunscreen ingredients to form a protective shield, defending against skin damage caused by UV rays, blue light, pollution, and climate-related stress in urban environments.

Anti-Photodamage - Comprehensive UVA and UVB Defense to Prevent Photoaging
The ECT1 sunscreen formula provides comprehensive protection against UVA and UVB damage, effectively preventing conditions like wrinkles, pigmentation, and dryness associated with photoaging. The active ingredient Ectoin also offers broad-spectrum UV and blue light protection, reducing inflammation caused by sun exposure, safeguarding skin's immune cells, minimizing free radical generation, and slowing down the aging process. Anti-Pollution - Powerful Defense Against Urban Pollutants
Airborne pollutants such as PM2.5/PM0.1 fine particles and heavy metals can damage skin cells, cause pigmentation issues, weaken the skin's barrier and immunity, and break down collagen, leading to wrinkles. Studies measuring skin biomarkers have revealed that Ectoin can mitigate the damage caused by these pollutants, alleviate skin inflammation, effectively enhance cell repair capabilities, and boost the skin's resistance to various urban pollutants.

Anti-Inflammation - Soothing and Repairing While Sunscreen Protects
Ectoin effectively soothes skin inflammation induced by sunlight while simultaneously repairing the skin barrier. Research shows that using Ectoin on damaged skin of various types leads to improvement. Experiments have demonstrated that 1% Ectoin can effectively reduce skin redness caused by irritants by 38% and significantly decrease skin moisture loss (TEWL) by 28%, thereby enhancing the skin's barrier repair ability.

Anti-Dryness - Enhancing Skin's Natural Moisture Retention Against Sun-Induced Dryness
One Ectoin repair factor can bind to four to five water molecules, forming a highly moisturizing Protective Hydro Complex. This complex envelops the perimeter of cells and biomolecules, creating a protective shield to prevent skin cell inflammation, improve UV-induced dryness, and combat aging. Ectoin enhances the skin's long-term moisture retention capability, with studies demonstrating that even after discontinuation for one week, the skin continues to exhibit high water-holding capacity, effectively fortifying the skin barrier.


Q1. Is SPF30 sufficient for sun protection?

SPF (Sun Protection Factor) measures the ability to delay UVB-induced skin damage. When comparing SPF30 and SPF50 sunscreens, their effectiveness differs by only about 1%. However, to achieve SPF50, sunscreen formulas tend to be heavier and greasier in texture.

Delay in skin damage:
SPF30 (5 hours)
SPF50 (7 hours) ➠ A difference of approximately 2 hours

UVB blocking effectiveness:
SPF30 (97%)
SPF50 (98%) ➠ A difference of only about 1%

The sun protection factor and formula texture are like a tug of war; sunscreen must strike a balance between a comfortable, lightweight texture and sufficient sun protection to encourage regular use. ECT1 Sunscreen is specifically designed for daily use, offering ample sun protection without feeling heavy. It is easy to apply and suitable for use before makeup, reapplication, or removal at the end of the day.

Q2. What skin types are suitable for ECT1 Sunscreen?

ECT1 formula is alcohol-free and fragrance-free, making it suitable for all skin types. Prior to using any product, perform a sensitivity test on a small area of skin on your inner forearm or earlobe.

Q3. What is the best method for applying sunscreen for optimal protection?

Applying sunscreen is a skill, and for an effective product, the right technique is crucial for comprehensive protection. Two key points for using sunscreen: apply an adequate amount and allow sufficient time.
We recommend applying sunscreen at least 15 minutes before going outside, allowing ample time for the sunscreen to form a protective film on your skin. This prevents sunscreen from transferring to your clothes or spreading unevenly on your skin, ensuring consistent protection. When using ECT1 Sunscreen, take a circular amount about 2-3cm in diameter, evenly apply it to your face, and use it 15 minutes before going outside. If you plan to apply makeup later, make sure the sunscreen is dry before doing so, and use a gentle patting motion to avoid rubbing it off. If you're sweating or spending an extended time outdoors, we recommend reapplying every 90 minutes.

Q4. What is the difference between chemical and physical sunscreens? Is physical sunscreen always better for the skin?

Chemical and physical sunscreens do not have an absolute superiority; each has its own strengths to meet the needs of different users.

Physical Sunscreen | Works by physically reflecting, scattering, and refracting UV rays.
Physical sunscreens primarily contain ingredients like titanium dioxide and zinc oxide, which are less likely to irritate the skin. However, they tend to have a heavier, greasier texture as the formula often requires a higher proportion of oil to ensure even distribution. Physical sunscreens may also leave a white or sweaty residue. Additionally, they generally offer weaker protection against long-wave UVA.

Chemical Sunscreen | Works by absorbing UV rays and converting them into heat.
Chemical sunscreens cover a broader range of protective wavelengths and typically offer better overall protection. They usually have a lighter texture, making them suitable for those who need a lightweight, comfortable sunscreen for makeup application or have skin that is better suited to such products.

Q5. Is ECT1 Sunscreen suitable for individuals with eczema?

In general, individuals with eczema may be more sensitive to chemical sunscreen agents (e.g., avobenzone, oxybenzone), but the ECT1 sunscreen formula does not contain these highly irritating chemical sunscreen agents. Furthermore, ECT1's active repair ingredient, 1% Ectoin, is widely used to alleviate eczema and skin inflammation, demonstrating its effectiveness in improving skin moisture and reducing transepidermal water loss (TEWL), thus relieving dryness and discomfort while providing sun protection. Dermatologists typically recommend physical sunscreens like titanium dioxide and zinc oxide for individuals with eczema. However, the suitability of each formula may vary, and some people may still experience adverse reactions to physical sunscreen agents. Therefore, it is recommended to perform a sensitivity test on a small area of skin on your inner forearm or earlobe before using any product or consult with a dermatologist.

Q6. How should ECT1 Sunscreen be removed?

ECT1 formula is designed for daily convenience and can be easily removed using regular makeup removers or cleansers. You can start by using makeup removers to cleanse the sunscreen, followed by a facial cleanser for thorough cleansing. Alternatively, you can use a dual-use makeup remover and cleanser.


Amount: Take an amount approximately 2-3 cm in diameter.

Application: Use sunscreen as the final step in your daytime skincare routine. Apply a sufficient amount of sunscreen evenly to your face, ensuring complete coverage of the areas that need protection. It can be applied to both the face and body.

We recommend applying it 15 minutes before going outdoors. If you plan to apply makeup afterward, please wait for the sunscreen to dry and form a film on your skin before doing so. Use a gentle patting motion to minimize any dragging of the sunscreen. If you sweat or spend an extended time outdoors, we recommend reapplying every 90 minutes.
