The quality of the product was immaculate if one's looking for food-grade glycerin from a healthy non seed, canola, or soybean oil based source. But glycerin in general acts on the skin by falsely appearing to hydrate it (in combo with water) when in fact, it causes severely rubbery and dehydrated from the inside out skin for the next several days. Great product if you're going to buy glycerin. But keep glycerin away from your skin and avoid eating it (can dehydrate your body from inside out).
