①The COB packaging colloid is directly exposed to the outside, it is made of silica gel, and the hardness is relatively soft. Avoid contact with sharp objects during installation, so as not to scratch the light-emitting surface and affect the light-emitting effect; ...
Silicone is bad for the skin On the other side of the fence are the detractors who say that silicones are in fact bad for the skin. Because the silicone sits in a layer on top of the skin keeping in moisture, it also keeps in any sebum, dirt and bacteria that may already be on th...
