As long as you see the appearance of these two ingredients that is undoubtedly physical sunscreen, followed by physical sunscreen texture is thicker, easy to whitish, oily, but physical sunscreen is more suitable for sensitive skin use.
Chemical sunscreen refers to the absorption of ultraviolet rays, converted into heat and then released to achieve the sunscreen effect. Usually chemical sunscreen texture is lighter, easy to push away, but the stimulation will also be greater.
