This is a mix of classic hip hop ring light and a slightly higher single source. I've done this a lot.
Ring lights are normally bigger bulbs arranged circularly on a board, and you stick your camera through the hole in the middle. They can be built or rented very easily and cheaply. As RnB videos evolved, the star-like arrangement of kino tubes radially became a staple. It reflects well in the eyes as well as in glasses. This is whats used in the video you referenced for all the shadowless stuff at around the 1:53 mark (BTW, Taral Hicks was the cute love interest of Robert DeNiro's son in the film A Bronx Tale).
Make sure you have a good makeup person that can add the correct sheen. It is key for that silvery, metallic look.
The other lighting is probably a slightly bigger source above camera. The way I normally do this when I do beauty ads is I get a Mole Big Eye 10K. They have a larger fresnel front lens that work very well for beauty portraiture. I undersling it on a goalpost and float it right above lens. To not nuke the talent, I normally change the bulb to a 2K via a step-down adapter that fits in the 10K (can be rented from most bigger rental houses). If that's not possible, one can dim it in conjunction with scrimming. But adding too much scrimmage can sometimes give a pattern that's visible, so best is the step down solution. This type of lighting can also be achieved in other ways - a small Briese, octadome or a built cutout solution. I've done all variations, but the Big Eye 10K solution always works for beauty.
Sometimes, when a more Helmut Newton or fashion flash light look is desired, you can use a smaller source that creates a sharper shadow. This can be anything, but the size will determine how sharp the shadow is. I've used PAR's, Dedo's and everything from a pea bulb up to a 5K to achieve this look.
Big Eye 10K on Garnier beauty ad I did. The underlights are what I call the Savides-lights as Harris used to use these for beauty fill. In general, when you're working with human eyes, you want round objects reflected in them. Any other shape has a tendency to look warped and strange due to curvature of eye. So to achieve this with square lights, one trick is to use round cutouts like I did on these panel-lights. Can be hard to tell in picture, but one can see that the right panel-light has this.
Example of old school ring light.
The star or radiating ring light used in tons of hip hop and RnB videos.
Example of using Savides-lights in bottom of eyes on a beauty ad I did. Doesn't work for everything, but it's a good trick for beauty fill light.
