I sometimes do promo images without it, especially if I want the "sparkles" and impurities. Sparkle doesn't work in SF very well and even less when you denoise the image. LOL.

By the mention of 'sparkles', are you actually referring to fireflies in the render?  Those are products of lighting most of the time especially if you are using HDRI illumination.  It is most apparent in lo-res HDR.  The best way to deal with those is to increase your number of pixels or change the HDR for a hi-res image.
