Protect your young one’s skin from ultraviolet (UV) rays

We want our children to have fun in the sun.
Our children have thin and delicate skin that is sensitive to UV rays, so we must guard them with UV protection.

About UV protection

Breakdown of Sunlight that Touches Earth
What are UV rays?

UV, especially UV-B, not only causes blotchy and wrinkled skin; it also has a high correlation to allergies as well as skin and eye diseases.
When humans absorb UV rays, our skin becomes red or dark brown, which is known as getting “tan.” Tanning is a type of low-temperature burn, so symptoms may vary from person to person.
In recent years, almost all harmful UV-B is absorbed by the ozone layer. However, with the destruction of the ozone layer, more UV-B has reached earth’s ground.

Playing outside is crucial to children’s growth.

Many think sunlight (UV rays) only has negative effects, but it also has many beneficial properties. It feels nice to play sports and spend time in the sun. Using a fluffy blanket that’s been dried out on the veranda can lull anyone to sleep. One can say the same for sun-soaked clothes.
It’s fun to play outside, especially for children. But as parents, we must protect our children with the appropriate UV care before they go out to play.

Why do children need UV protection?

By the time they are 18-years old, humans are said to have absorbed half of the UV rays they’ll absorb in their lifetime. Babies have fragile skin that is too young to produce UV-blocking melanin. Therefore, it is important to protect children from UV rays from a young age.
From the time children are born to when they’re 8-9 years old, they are especially at risk of contracting skin disease when they absorb strong UV rays. Their bodies do not produce enough sebum, which exists on the skin’s surface and is said to block UV rays out.
Let’s safeguard our children with UV protection when they frolic outside or play sports, as early as we can.

How can we protect our children from UV rays?
  1. 1.Avoid letting them pay outside around 12pm, when UV rays are strongest.
    Especially in spring and summer, your child will absorb the least amount of UV rays if they stay inside from around 10 am to 2 pm.
  2. 2.Wear clothes and hats that block UV rays
    • ① Children should wear hats or long sleeved-outerwear when they play outside.
    • ② Apply UV-blocking cream to your child’s skin and avoid short-sleeved clothing. Please apply the cream as gently as possible.
    • ③ Buy extra shade for your stroller.
    • ④ After getting out of the water at a beach or swimming pool, make sure your child rests in the shade and wears a towel to protect their body from sunlight. Then, reapply UV-blocking cream to their skin.
  3. 3.Have an interest in UV care together
    Parents and children should wear hats and apply UV-blocking cream together. Having children participate in UV protection themselves is the key to educating them on the importance of UV protection.

“We must protect our children from UV rays”

Dr.Masamitsu Ichihashi, Doctor of Medicine, Kobe University School of Medicine Honorary Professor. Director of Kobe Saisei Mirai Clinic President of Japanese Committee for Sunlight Protection.

There are 60 trillion cells in the adult human body but only 3 trillion in a newborn baby. By the time children move from infancy to adolescence, their cells have already multiplied twenty times over. The number of damaged and immobile DNA cells increase when growing cells are exposed to UV rays. UV rays are the cause of skin cancer and poorly-aged skin. Since the sun’s UV rays have recently become stronger, young children must wear UV block for at least one year. UV rays are powerful and invisible to the human eye, so their harmful effects may go unnoticed. All parents must take caution and make a habit of preventing UV damage.

Frequently asked questions

Question1What is a “UV cut rate?”

Using special testing equipment, we expose our products (fabric) to UV rays and measure the percentage of rays they block. The products that completely block UV rays have a UV cut rate of 100%. MIKI HOUSE products with a UV cut rate of 80-90% or more have also undergone this process.

*The UV cut label is mainly attached to a portion of our swimwear, hats, and outerwear. This label is not attached to all of our products. Please check the label before purchasing.

Question2Do MIKI HOUSE’s products undergo a special UV-blocking process?

Our products do not undergo a special UV-blocking process. Our woven/knitted products are made from high-quality fabrics that contain a high UV cut rate. Since this UV-cutting property is not a result of post-processing, even if you wash our clothes it will retain a high UV cut rate. You can safely use our items every day without worry.

*Please check each product’s tag for washing instructions

Question3What is UV-blocking cream?

It is a cream developed by MIKI HOUSE that you can safely use on your young children to prevent sunburn. Click here for details.

Question4Why is UV-blocking cream good for children? Please explain its benefits.

Regular sunblock contains absorbent and reflective chemicals that block UV rays. These absorbent chemicals absorb UV-B and generate heat, which irritates and heats the skin. The reflective chemicals reflect UV-A but at times have the appearance of white, blotchy makeup. Our UV-blocking cream contains our original ingredient, Oxidized Titanium (Y Titanium), which traps UV rays. It also blocks over 99% of UV-A and UV-B and protects your skin from harmful UV rays. Additionally, Geranium Robertianum Extract and other components act as a moisturizer that protects the skin against dryness. Gently apply the cream to your child’s skin; there is no need to apply a thick layer. UV-blocking cream does not require any special cleaning methods and can be easily washed away with soap.

Question5What is the SPF and PA values of the UV-blocking cream?

SPF is a value that represents how much a product can block UV-B, while PA represents how much a product can block UV-A. UV-blocking cream blocks over 99% of UV-A and UV-B. As long as the cream is applied to the body, the cream will continue to block the sun’s harmful rays. Therefore, UV-blocking cream is not measured by SPF or PA; it is measured by the UV cut rate.

*The effects of UV-blocking cream wear off with friction, sweat, and water, so please reapply the cream frequently.

*If your child has been in direct sunlight without shade for over one hour, please reapply cream as necessary.

Question6My child has sensitive skin. Should I use the UV-blocking cream?

Although our products are tested safe for everyone, try rubbing a little cream on your child’s sensitive spots before applying it to their body or face. You may also use it after consulting your doctor for children currently admitted in the hospital for skin trauma.
