May, the month of family, is a busy time for many families preparing to go out to places like zoos, amusement parks, and festivals while holding their children's hands. Since the ultraviolet (UV) index rises significantly in spring, it is essential to bring sunscreen when going out to protect skin health. How should you choose sunscreen for children?

Babies' skin, which is more sensitive than adults', can react more sensitively to hot sunlight, so it is necessary to block UV rays more thoroughly. Sunscreens protect the skin from ultraviolet A (UVA) and ultraviolet B (UVB) rays. UVA affects skin tanning and aging, while UVB can cause surface burns in a short time.

UVA protection is indicated by the PA rating, and UVB protection is shown by the Sun Protection Factor (SPF). SPF ratings below 50 are shown by their numbers, and 50 or above is indicated as 50+. PA ratings are displayed as PA+, PA++, PA+++, and PA++++. The higher the number or the more plus signs, the better the protection, but since higher levels use more UV-blocking ingredients, it is important to check if the skin reacts sensitively. The World Health Organization (WHO) recommends using sunscreen from six months of age when going outside.

Most skincare products specialized for infants and toddlers are composed of much milder ingredients than adult cosmetics. Zero to Seven’s Gungjung Bichaek Waterful Sun Lotion Mild contains 100% zinc oxide as a physical UV filter and a gentle formula. It forms a thin layer on the skin surface like a shade, reflecting UV rays to block them. Physical UV filters contain fewer chemical ingredients than chemical UV filters, making them less irritating to the skin.

Fast absorption into the skin is an essential factor for infant cosmetics. Since babies tend to put everything in their mouths during the oral phase, it is important to have the product absorbed immediately after application to prevent the ‘unfortunate incident’ of swallowing cosmetics. Gungjung Bichaek’s product has a very moist application and maintains a fresh feeling all day without stickiness. It is a lotion type with a somewhat thin consistency. It is best to apply sunscreen carefully 15 to 30 minutes before going outside. The lightweight formula allows for frequent reapplication during outdoor activities without discomfort. After completing various clinical tests and gaining ingredient stability recognition, it has successfully entered the Japanese market, which is known for its strict cosmetic regulations.

When using sunscreen on children for the first time, it is advisable to apply a small amount on the inside of the wrist to check for any sensitive skin reactions. Infants under six months have thin skin layers and high sensitivity to external substances, so sunscreen use should always be consulted with a specialist. If any allergic reactions or skin irritation occur while using sunscreen, stop use immediately and consult a professional.
