Hi, I’m Mimi! A Japanese mom in my 30s, aiming for a low-additive lifestyle for my family.
Are you protecting your baby from the sun?
There are so many kinds of sunscreens at baby stores and drugstores in Japan that it can honestly be hard to know which one to choose.
In this article, I’ll introduce 10 safe and gentle sunscreens that are suitable for babies and also for moms.
This guide is for you if you are..
- looking for gentle sunscreens for babies in Japan.
- looking for sunscreens you can use together with your children in Japan.
- not sure which sunscreen to buy in Japan.
What Makes a Sunscreen Safe for Babies?
When choosing sunscreen for babies, we want something gentle on delicate skin and safe even if a tiny amount accidentally gets into their mouth.
There are 4 things that I look for when choosing a baby-friendly sunscreen.
● Additive-Free
Look for products labeled 「無添加」 (Mutenka).
Try to find sunscreens that are:
- Fragrance-free
- Colorant-free
- Ethanol-free
- Paraben-free
Organic products are also recommended because they tend to be gentler on the skin.
● High Percentage of Naturally Derived Ingredients
Naturally derived ingredients are generally gentler on the skin and are often easier to wash off with soap.
Ideally, choose products made with 100% naturally derived ingredients.
● Non-Chemical Formula (UV Absorber-Free)
It’s important to choose sunscreens that do not contain chemical UV absorbers, which are sometimes said to cause skin irritation.
Look for phrases like 「紫外線吸収剤不使用」 (Shigaisen kyūshūzai fushiyō) or 「ノンケミカル」 (Non-kemikaru) on the package.
● Easy to Wash Off with Soap
The best sunscreens are the ones that can be removed with regular soap during bath time, without needing special cleansers.
Check for the phrase 「石けんで落とせる」 (Sekken de otoseru).
※ These recommendations are based on general information only.
Please always monitor your child’s skin condition carefully and consult a doctor if you notice any irritation or unusual reactions.
Types of Sunscreens
There are different types of sunscreens.
The key is choosing one that fits the situation and is easy to apply on your child.
