>☀️ The first line of defense for baby sun protection is not to apply, but to "wear the right clothes"

When summer comes, the first preparation for many parents is to buy a bottle of "children's sunscreen" for their children.
However, dermatologists and pediatric experts unanimously remind: For infants and young children, the most reliable way to protect against the sun is not to apply sunscreen, but to take physical measures, such as wearing clothes with professional sun protection functions, especially UPF sun protection swimsuits and sun hats.

👶 Why do children need more physical protection?

Children's skin is more delicate than adults, and their ability to defend against ultraviolet rays is naturally weaker. This is not an exaggeration, but has a clear medical basis:

1. Thinner stratum corneum: Children's stratum corneum is not fully developed, and it is difficult to effectively block ultraviolet penetration

2. Shallow dermis: Ultraviolet rays can more easily penetrate into the deep layer of the skin, inducing sunburn or pigmentation

3. Fewer melanocytes: Insufficient "natural shield" to defend against ultraviolet rays, poor resistance

4. Insufficient sebaceous gland secretion: Unable to form an effective sebum membrane barrier, more prone to dryness or irritation

According to the guidance of the American Academy of Dermatology (AAD) and the American Academy of Pediatrics (AAP), infants under 6 months old should avoid using sunscreen and should completely avoid direct sunlight when going out, and children over 6 months old should also use "wearable protection" as the first choice for sun protection.

🧴 Sunscreen is not a panacea, especially for children's skin

Although "children's sunscreen" has become a must-have product in the market, we must also face up to its limitations:

Potential problems ---- Causes or consequences

1. Uneven application ---- Children like to move, often miss the application or are quickly wiped off by sweat and friction.

2. Frequent reapplication is required ---- Most sunscreen products are only effective for 2 hours, and need to be reapplied immediately after swimming.

3. Possible irritation ---- Some sunscreens such as oxybenzone and octinoxate may cause skin irritation, rashes or allergic reactions.

4. Contains chemical ingredients ---- Even if it is a "children's formula", it may still contain potential allergenic ingredients or nanoparticles.

Therefore, "sunscreen + physical protection" should be a double insurance for parents' sun protection strategy, rather than relying on only one of them.

🩱 What is "physical sunscreen"? Why do we recommend sunscreen swimsuits?

Physical sunscreen refers to directly blocking ultraviolet rays through fabric structure and fabric technology without being absorbed by the skin, so it is more suitable for children. Compared with traditional cotton clothing, professional sun protection clothing usually has the following technical advantages:

UPF (Ultraviolet Protection Factor) certification: The higher the UPF value, the lower the UV penetration rate.
🔍 Ordinary T-shirts are about UPF5-10, while UPF50+ can block more than 98% of UVA/UVB

High water resistance: Even in swimming or sweating environments, it does not affect the protection ability.

Large coverage area: Long sleeves and long pants structure are more suitable for the protection needs of infants and young children.
