I took both of those effects (slightly renamed) from Magi of Hermes.
Oops. My goof. I should have known better. I'll fix that.
The Face of Paris
PeCo 14
Pen +0, unlimited uses/day
R: Touch, D: Mom, T: Ind
This razor, although blunt, will remove any and all body hair where it touches the skin of a human. The item has no penetration built into it, so a magus has to suppress his Magic Resistance while shaving. Aurulentus’ wife had always complained that his beard growth was too strong; after a twilight experience his facial hair growth increased manyfold and Aurulentus invented this lesser enchanted device to keep it under control.
(Base 3, +1 Touch, +10 levels unlimited uses)
[Magi of Hermes, page 24]

Phantasmal Troupe
CrIm 15
R: Voice, D: Conc, T: Ind
Creates illusionary music from a direction that the caster specifies. A full troupe of musicians can be simulated in this way, with a finesse roll determining the quality of the music. Aurulentus uses this spell to amuse his wife and children. It was originally invented by his parens, Altus, with the same motivation.
(Base 1, +2 Voice, +1 Conc, +2 change at command, +1 intricacy)
[Magi of Hermes, page 22]
Do you have these entered into MetaCreator? Did I see that you had that? If so, I'll PM you my email address so you can let me see your character and items (makes it easier to check the math on me).
Magi of Hermes is probably one of the worst books as far as having different interpretations of the rules result in a vast array of spell possibilities. I lean towards the conservative.
Phatasmal Troupe is problematic. The Guideline is create a sound, and the +1 for intricacy allows for creating either beautiful music from a single source or an intelligible voice (not noise). And the insert on page 144 says, "In addition, very intricate images (for example, an intricately ornamented bridge) are generally one level of magnitude higher as well" suggests that at least one more level of intricacy is required, but I lean towards it being +2 for Group... I'll let the troupe opine, but we're needing at least +1 magnitude for more intricacy or +2 for Group.
The hair is definitely a T:Part, and an error in Magi of Hermes, although it isn't in errata. A later, similar example is in Apprentices, The Clerics Pate and that uses T:Part. T:Ind would remove all the hair on a person, which is not the goal.
I'll see if I can squeeze the extra BPs into my build. If I can't, I'll drop an item. I can only afford so many 'color' items. I've already spent 82 BP on them. 
Okay, edited. That's an extra 6 BP.
I just hope I don't regret this when the vampires attack!

Edited to account for aging, since I forgot that aging was a stress die w/o botch instead of a simple die.
Edited to add talisman and bracelet of invisibility.
So I think I have this set, but I wanted to make sure. Being 64 years out of gauntlet, Catrina would have 320 BP, 32 of which could be taken as vis.
Of the 320 BPs, she's spent:
[table][tr][td][center]227[/center][/td] [td]Magic Items[/td][/tr]
[tr][td][center]30[/center][/td] [td]Lab[/td][/tr]
[tr][td][center]32[/center][/td][td]Vis[/td][/tr]
[tr][td][center]289[/center][/td] [td]TOTAL[/td][/tr][/table]
That leaves her with 31 left to spend.
She has 32 BP of vis = 160 vis, she's spent:
[table][tr][td][center]9[/center][/td] [td]Longevity Ritual[/td][/tr]
[tr][td][center]27[/center][/td] [td]Talisman[/td][/tr]
[tr][td][center]36[/center][/td] [td]TOTAL[/td][/tr][/table]
That leaves her with 124 vis left over.
Do I have that right so far?
Just as long as you understand it's not 17 pawns (and I think you do, I'm just saying this with an abundance of caution), but 17 build points of vis. Note, you don't have to spend it as vis, either. You can buy other things with it, just that you cannot have spent more than 32 build points as vis.
I suggest getting your hands on some tractatus that you'd might like to read.
Catrina's actions for spring and summer:
1271/Spring: Invent Lifting the Dangling Puppet ReCo15 and Spasms of the Uncontrolled Hand ReCo5, (Lab Total = 41)
1271/Summer: Invent The Call to Slumber ReMe10 and The Snap of Awakening ReMe10, (Lab Total = 41)

43 BP in tracti
This leaves 20 BP for vis = 100 vis
35 vis spent, as noted above.
This leaves Catrina with 65 vis
Let's call it:
- 30 Im
- 10 Co
- 10 Vi
- 5 Cr
- 5 Me
I realize that while I worked up Catrina's labs, I don't think I ever posted them. So here they are.
[hr][/hr]
[size=150]PRIVATE LABORATORY[/size]
Catrina’s laboratory and sanctum are located in a small tower on the school grounds. But it rarely looks like itself. Catrina typically enchants it to look like an oak tree, a hovel, a nice cottage, a menhir, a large statue, a faerie tale tower, or even a stone wall.
