Well, the physical appearance really is that ‘glow’ about you… IS will give that impression to others, when you get comments like ‘you’re looking radiant today!’… some people will attribute that to a good nights sleep, a good diet, etc. IS will give that vibe as well, though, it may not be as effective if you wake up, put on some sweats, don’t shower, and go out for coffee at Buckystars…
As to layering BOTH IS/a and IS/b, well, I’m not sure on that… I would think that the IS/a with IS and IO could work out to a Happy to be around you, Easy to talk to, sexy and strong Angelina Jolie…
But, both IS/a and IS/b… well, I’d post that question in the women’s forum and get some of the ladies involved who have used both products. I know my wife feels much more comfortable and laid back and women and men seem to be attracted to her kittenish IS/b vibe. She had tried the IS/a and it tended to be a bit aggressive in her.
Take a look at a brief history on mones and why it’s recommended to layer the products to get the results you want here:
I’ve heard it described best like a painting. You can imagine your skin as your canvas and the mones as your colors. When you mix them together you can create some fantastic combos for work, school, play, with family, etc. Then, take a good shower (I use Dial 3D soap, BTW 
) and your canvas is ready for the next painting you wish to create!
Oh, and I’ve used IS and IH when I’ve done massage’s. The women have been relaxed and at ease with an easy communication about their pain and needs. I’d suggest you give IS a try with your clients and observe their reactions…
