PA is an important rating that can help guide your selection when it comes to skin care products. The PA rating system measures the level of protection specifically from UVA rays, which are known to cause skin aging and pigment darkening in the skin. It measures the amount of time a product would protect your skin from darkening. To learn more about the PA rating system and what makes PA++++ the highest rated level of protection, read our “What is PA++++? Guide”.
Colorescience® UV protectors are great for those with combination skin which is typically characterized by dry, flaking skin on the cheeks, while excessive oil and shine appears on other areas of the face.
