Passed Dermatest® Sensitive Skin Testing in Germany
『 5-Star Safe In Use Test on Subjects Aged 0–12 Months 』
『 Patch Test on Subjects with Atopic Dermatitis-Prone Skin 』
No product-related irritation or adverse reactions were observed in any subject.
Complies with stringent EU standards.
Awarded the highest 5-Star “Excellent” seal.
Wonder Healing Cream has successfully passed rigorous testing procedures and was awarded the highest 5-Star “Excellent” seal by Dermatest®. To better reflect the real needs of sensitive and delicate skin, the product was tested on highly sensitive groups: subjects aged 0–12 months and subjects with atopic dermatitis-prone skin.
- Safe In Use Test (5 Star): 20 subjects aged 0–12 months used the product continuously for 4 weeks. Application area: face.
- Patch Test: 20 subjects with atopic dermatitis-prone skin underwent patch testing, with continuous observation at 24, 48, and 72 hours. Application area: back.
Throughout the testing period, no product-related allergic reactions or adverse reactions were observed in any of the subjects. This demonstrates the product’s excellent safety profile and high skin tolerance when used on sensitive and atopic dermatitis-prone skin.
For sensitive skin, the face is one of the areas most prone to visible reactions. In addition, the skin barrier of infants aged 0–12 months is not yet fully developed, making them highly susceptible to irritation. This requires the product to meet an exceptionally high standard of mildness, safety, and skin tolerance.
We chose to verify our product under these more demanding conditions because true confidence must be supported by evidence. This certification is more than a seal — it represents our highest commitment to quality and to the health of our consumers’ skin.

Core Testing Items
Patch Test
Evaluation Focus: Primary Irritation and Contact Allergic Reactions
The test substance is applied to the subjects’ backs using an occlusive patch method. The results are then read and evaluated by trained professionals in accordance with standardized protocols. During the 24- to 72-hour observation period, the skin is assessed to confirm that no reactions such as erythema, swelling, irritation, or allergic responses are observed.
Safe In Use Test (5 Star)
Evaluation Focus: Skin Tolerance and Safety Under Continuous Use
The test is designed to simulate real-life daily use. Subjects use the product continuously for more than 4 weeks, while trained professionals conduct regular follow-up assessments to monitor skin condition and reactions, including dryness, itching, redness, stinging, and flaking. The highest 5-Star rating may be awarded when no product-related adverse reactions are observed throughout the entire testing period.
