✦ What problems does this sunscreen solve for you?

• Sunscreen is too heavy and greasy; I don't want to apply it in summer.

• Physical sunscreens leave a white cast, cause white streaks when sweating, and mess up makeup.

• My skin still feels dry and tight even after applying sunscreen.

• I want sun protection and skin repair without adding an extra step to my skincare routine.

• Concerns about certain sunscreen ingredients for eczema or sensitive skin.

✦ Why is ECT1 the new standard for skincare-grade sunscreen?

① Ectoin — Repairs photoaging alongside sun protection
Ectoin is a natural protective amino acid derivative sourced from microorganisms in extreme environments, used to shield cells from extreme environmental stress. In skincare, Ectoin effectively protects skin cells from UV-induced oxidative stress, reduces photoaging damage, while enhancing skin hydration, reducing TEWL (Transepidermal Water Loss), and soothing dryness and discomfort. ECT1 contains 1% active Ectoin, elevating sunscreen from "UV blockage" to "sun protection and repair."

② Triple Broad-Spectrum Chemical Sunscreens — SPF30, Full-spectrum Protection
ECT1 uses a combination of three safely verified chemical sunscreen ingredients:

• Ethylhexyl Methoxycinnamate: Effectively absorbs UVB.

• Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S): Broad-spectrum protection against UVA + UVB, with extremely high photostability.

• Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus): Targets long-wave UVA protection, compensating for the inadequacy of traditional chemical sunscreens in protecting against UVA.

These three ingredients work synergistically to provide full-spectrum broad protection, effectively blocking 97% of UVB, while also addressing deep UVA damage, offering a more comprehensive protective solution than single sunscreen ingredients.

③ SPF30 is sufficient — higher SPF often comes at the cost of being greasier
SPF30 blocks approximately 97% of UVB, while SPF50 blocks 98%, a difference of only about 1%. However, to achieve SPF50, formulas typically require a higher concentration of sunscreens, resulting in a heavier and greasier texture. ECT1 chose SPF30 to strike the optimal balance between sufficient sun protection and a light, comfortable texture, making you truly willing to apply it daily and develop good sun protection habits.

④ Lightweight and sheer, no white cast or pilling, seamless under makeup
The biggest advantage of chemical sunscreens is their light and transparent texture. ECT1 contains no physical sunscreens, so there is absolutely no white cast issue, and it's alcohol-free, making it non-irritating to the skin. The Japanese R&D team meticulously perfected the texture to ensure no pilling or flaking after film formation, even under makeup, truly achieving skincare and sun protection in one step.

⑤ Triple plant-based soothing agents, also suitable for sensitive skin
The formula includes three plant-based soothing ingredients: Citrus Unshiu Peel Extract, Houttuynia Cordata Extract, and Artemisia Capillaris Flower Extract. Coupled with Dipotassium Glycyrrhizate for anti-inflammatory effects, it comprehensively calms the skin, reducing irritation after sunscreen application. Sensitive skin can also comfortably use it daily.

✦ Benefits

• Broad-spectrum protection: SPF30 blocks UVB + UVA, preventing sunburn and photoaging.

• Repairs photoaging damage: Ectoin protects skin cells from UV oxidative damage.

• Deep hydration and moisturizing: Ectoin + Sodium Hyaluronate enhance skin moisture and reduce TEWL.

• Soothes and calms: Multiple plant extracts + Dipotassium Glycyrrhizate reduce inflammation and sensitive reactions.

• Repairs skin barrier: Ectoin is especially suitable for eczema and sensitive skin, relieving dryness and discomfort.

✦ Texture

Lightweight and sheer lotion, refreshing and comfortable, completely free of white cast or white streaks from sweat. It quickly forms a film after application, is non-sticky and non-pilling, ensuring makeup applies smoothly afterward. Suitable for all seasons and can be used on both face and body.

✦ Active Ingredients

Ectoin — 1%
A natural amino acid derivative from microorganisms that thrive in extreme environments (high salt, high temperature, strong UV). It protects cellular structures from environmental stress. In skincare, Ectoin shields skin cells from UV-induced oxidative damage, repairs photoaging, enhances skin hydration and barrier function, and soothes inflammation and sensitivity. It's a gentle repairing ingredient often found in eczema and inflammatory treatment formulas.

Ethylhexyl Methoxycinnamate (UV Filter)
A classic UVB chemical sunscreen, highly effective at absorbing UVB rays (290–320 nm) to prevent sunburn. It is one of the most widely used chemical sunscreens globally.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S)
A new-generation broad-spectrum organic UV filter that absorbs both UVA and UVB. It boasts extremely high photostability, resisting degradation from sun exposure and effectively extending overall sun protection efficacy.

Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus)
A highly effective UV filter targeting long-wave UVA (320–400 nm), it compensates for the insufficient UVA protection of traditional formulas, further reducing the risk of deep skin damage and photoaging caused by UVA.

✦ Formulator Q&A

Q: Is SPF30 enough for sun protection?

A: SPF (Sun Protection Factor) indicates the ability to delay UVB-induced sunburn. SPF30 blocks approximately 97% of UVB, while SPF50 blocks 98%, a difference of only about 1%. However, to achieve SPF50, formulas are usually heavier and greasier, making people less willing to apply them daily, which reduces actual sun protection effectiveness. ECT1 uses SPF30 to achieve the best balance between sufficient sun protection and a light, comfortable user experience, truly encouraging daily sunscreen application.

Comparison of extended sunburn time:

• SPF30: Approximately 5 hours

• SPF50: Approximately 7 hours (a difference of about 2 hours)

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

A: There is no absolute superiority between the two; each has its suitable use cases:

Physical sunscreens: Block UV rays through physical reflection, scattering, and refraction using titanium dioxide (TiO₂) and zinc oxide (ZnO). The ingredients are less irritating, making them suitable for sensitive skin. The downsides are that formulas are usually heavier and greasier, can leave a white cast or white streaks when sweating, and offer weaker protection against long-wave UVA.

Chemical sunscreens: Absorb UV rays and convert them into heat, which is then released. They cover a broader range of wavelengths, offering more comprehensive protection. The texture is usually lighter and sheerer, and makeup applies more smoothly afterward, making them suitable for daily commutes and those who apply makeup after sunscreen.

ECT1 uses chemical sunscreens, without common irritating ingredients like Avobenzone and Oxybenzone, and includes Ectoin for repair, achieving an optimal balance between protection and skin comfort.

Q: Is ECT1 sunscreen suitable for people with eczema?

A: The ECT1 formula does not contain highly irritating chemical sunscreens such as Avobenzone and Oxybenzone, making it more suitable for individuals with sensitive skin. The Ectoin in the formula is also a common repairing ingredient used in eczema and inflammatory treatments; it enhances skin hydration, reduces TEWL, and alleviates dryness and discomfort, providing both sun protection and skincare benefits. However, it is still recommended to perform a patch test before use or consult a dermatologist.

Q: How do I remove ECT1 sunscreen?

A: ECT1's formula is designed for daily convenience and can be easily removed with regular cleansing products. You can first use a makeup remover to take off the sunscreen, then follow with a facial cleanser to thoroughly wash your face, or use a two-in-one cleansing product for a single-step removal.

Q: How to apply sunscreen correctly for optimal protection?

A: Correct application is just as important as the sunscreen product itself:

Sufficient amount: Use an amount about 2-3cm in diameter each time, and apply evenly to the face and any body parts needing protection, ensuring complete coverage.

Allow time for film formation: Apply 10-15 minutes before going out to allow the sunscreen to fully set on the skin. When applying makeup afterward, wait until it is completely dry and set, then apply by gently patting to avoid disturbing the sunscreen layer.

Regular reapplication: If sweating or engaging in prolonged outdoor activities, it is recommended to reapply every 90 minutes to ensure continuous protection.
