Frequently asked questions about sun protection products in general.
The Sun Protection Factor (SPF) measures the amount of time sun damage is delayed for a certain product, and SPF is different for different products. The numbers cannot be simply added together. However, layering UV protection products rather than using just one will increase your protection factor. Layering sun protection cream and foundation is particularly effective.
SPF stands for Sun Protection Factor, and is a measure of how well a product will protect your skin from UVB rays (which initially make the skin red and swollen, then make it turn brown). For example, you may see products with an SPF of 15 or 30; the larger number mean the product will better protect your skin from UVB rays, which is useful when comparing the efficacy of different products. As SPF 50 (when used correctly) prevents inflammation from UVB even in locations with extremely high levels of UV radiation and in people who are sensitive to UV rays, a factor of higher than SPF 50 is labelled as “SPF 50+”.
PA refers to the UVA protection grade, and shows how well a product will protect you from UVA rays (which turn your skin brown, and make it lose elasticity in the long term). The degree of protection is expressed as PA+ (effective), PA++ (very effective), PA+++ (extremely effective) and PA++++ (maximum effectiveness), so the more “+”es, the more you are protected from UVA rays.
If you store your sun protection products properly, it is possible to use last year’s products. Their protection factor will be basically the same. Make sure to wipe the opening of your sunscreen immediately after use, then return the cap properly before storing it in a location out of direct sunlight with a constant temperature. However, avoid use if you notice a strange odour or that the product has separated, as this means the product quality is compromised. As much as possible, we recommend using up new products within that season.
The skin of young children is far more thinner than that of adults, and as it has not matured yet, it is sensitive to external irritants.
Because of this, we recommend using a special sunscreen for young children.
What’s most important, is avoiding exposure to UV rays for long periods of time.
When outside, protect your skin from direct sunlight with an umbrella or a hat.
Ultraviolet absorbers protect the skin from the effects of UV exposure as they absorb UV rays and release them away from the skins surface. There’s no need to worry about them making your skin hotter or more prone to UV absorption. Their safety on skin has been confirmed. However, as with any beauty product that contains a special ingredients such as ultraviolet absorbers, occasionally an allergic reaction may be caused. In this case, you should consult with a dermatologist as soon as possible.
Ultraviolet scattering agents are mainly powder, and they scatter UV rays that hit the skins surface away from the skin, protecting the skin from the effects of UV exposure.
“Non-chemical” products do not contain any ultraviolet absorbers.
Ultraviolet absorbers selectively absorb UV rays, protecting your skin from sun damage and your make-up from quality deterioration caused by their harmful effects. They are found in not just sun protection products, but also in beauty products and quasi-drug products such as base make-up and eye, lip and cheek make-up. It is said that non-chemical is better for the skin, but the ultraviolet absorbers we use are very safe, and you can use our products with peace of mind.
