The gel smells for me just fine. But that's a matter of taste and very subjective.
After 2-3 "treatments" was the color with me. Provided mainly in places for example, with the cornea are (knees, hands, etc) results in a significantly more powerful sound, which is very unnatural. Thus, it affects overall very spotty.
The color of "normal" body regions was rather yellowish, looked as if I had huge bruises. In the places with corneal it was rather dark orange.
Come to me, therefore, no longer in question. Possibly it is the light skin type.
