**Formulation Thoroughly Considered for Children's Skin**
Moisturizes and protects delicate, dry, and barrier-impaired sensitive skin and children's skin, while providing UV care simultaneously!
**1) Focuses on barrier, moisture, and skin microbiota to prevent UV rays**
* Barrier: Inspired by vernix caseosa, 8 types of vernix-like ingredients, Baby's Emulsion®, and 4 types of human-derived ceramides enhance the skin's barrier function.
* Moisture: A moisturizing veil of 2 types of Lipivida® protects the skin from dryness.
* Skin Microbiota: Formulated with Extracell-Oligocura® and Bifidobacterium extract, which promote beneficial skin bacteria, based on a pre & probiotic concept.
* UV Care: Protects against UV rays with a gentle, non-chemical formulation. Additionally, it contains ingredients like Edelweiss Extract and Gentiana Root Extract to prevent skin irritation caused by UV rays and dryness, leading to healthy skin.
**Mama & Kids Moist UV Milk Data on Moisture Level Changes and Transpiration Volume Changes**
Data shows high moisture levels starting one hour after application, persisting for six hours. Moisture transpiration levels were low from one hour after application. Both data sets suggest that this product effectively moisturizes the skin, enhances the skin's barrier function, and protects it.
**2) Light and non-sticky feel!**
We pursued a texture that makes you want to use it every day, focusing on the soft skin feel unique to emulsion, the absence of white cast and stickiness, and good blendability. Not only can it be applied after washing your face, but it blends in quickly even when applied in a rush in the morning, and is designed not to transfer to clothes or hats. Its fresh and light texture makes it comfortable to use as a UV emulsion for the entire body, not just the face.
**3) No cleansing required! Can be removed with a low-irritation cleanser!**
It can be easily removed with Mama & Kids Mousse Mild Whip from the same series. Simply spread the foam and let it blend in. It can be removed without harsh rubbing, reducing burden on the skin and allowing for safe use.
**4) Formulation developed with a primary focus on skin gentleness**
Products developed in collaboration with pediatricians, dermatologists, and allergy specialists. Ingredients that could cause irritation are thoroughly eliminated. To ensure safe daily use, various safety tests and allergy tests are conducted in cooperation with medical institutions.
*Skin patch test completed on sensitive skin*1
*Eye irritation test completed*2
*Skin allergy test (RIPT) completed*3
*Food allergy test completed*3
*1 Not everyone will experience the same results. *2 Not everyone will be free from irritation. *3 Not everyone will experience allergies.
**Bottles that Encourage Children's "Doing it Myself"**
**1) Fresh inner bag adopted for hygienic use until the end**
Manufactured in our company's clean rooms, which boast hygiene standards comparable to pharmaceutical manufacturing facilities. The container uses a double-structured bottle (container with a fresh inner bag system) to prevent the contents from coming into contact with air, allowing for fresh and hygienic use until the very end.
**2) Compact container designed for easy independent use**
Designed to be easily held with one hand, even by small hands, and to allow for firm pushing. Its compact size makes it unobtrusive when placed in a washbasin, living room, or children's room. With a simple usage of 1-2 pushes per application, children can complete their morning skincare routine by themselves.

**Mama & Kids Sensitive Skin Face Care Dream Design Bottle Lineup**
A skincare series for children, born from the wish that they create "cuteness" with their own hands.
For the basic skincare habits of "washing" and "protecting," three selected items from Mama & Kids Sensitive Skin Face Care have been updated to "Dream Design" bottles that children can use with "their own hands."
The design, conceived with a 6-year-old girl who dreams of becoming a designer, allows for the creation of a one-of-a-kind "My World" bottle by attaching the included stickers.
**Mama & Kids Mousse Mild Whip (Dream Design)**
155ml ¥2,035 (tax included)
* A low-irritation foaming facial cleanser perfect for starting skincare. Its weakly acidic amino acid-based foam is gentle on the eyes and removes dirt thoroughly while retaining moisture for children's thin and easily irritated skin.

* Comes with stickers featuring unicorns, stars, rainbows, etc., evoking a sky theme.
