What Nature has Neglected , Bonisagus has Perfected
MuCo
Level 10
R : Personal / D : Sun / T : Part
This spell doubles the breast size of a Maga.
A similar spell for the "lower regions" exists for male Magi.
(Base 03 / +02 Sun / +01 Part)
Scent of the Spring Flower
MuCo(He)
Level 15
Requisite : Herbam
R : Sight / D : Sun / T : Ind.
The target of this spell is given the scent of a typical flowering plant native to the area.
This could make the target particularly attractive to bees.
In other environments this spell may add a bonus to Social Engagements or to being tracked.
(Base 02 / +03 Sight / +02 Sun / Requisite Free)
With an Animal requisite , the target may be given the scent of a particular natural creature.
A variation of the original spell would give the target the scent of clover ,
making the target attractive to various ruminants ,
who may try to nibble on you.
True ME females (and their male admirers) would almost certainly fail to understand the merit of this spell 
- it you look at the ideals depicted in Art - breasts were viewed primarily as a way of feeding infants - and seem to have preferred a more pear-shaped figure with small "apples" on the chest, and a large "fundament" below...
Oh well , my knowledge of 13th aesthethics of beauty being somewhat limited. 
This spell is easily modified to increase the size of more "fundament"al aspects.
Remove the Unsightly Blemish
R : Voice / D : Mom / T : Ind
Level 05
PeCo
This spell removes all skin growths from the target.
Any warts , moles , minor scarring (from pimples , but not from the Pox) are removed.
(Base 03 / +02 Voice)
Smooth as a babies bottom
R : Per / D : Mom / T : Part
Level 04
PeCo
This spell removes all facial hair from the magus.
Higher magnitude versions of this spell exist for removing the beards of dignified academics , german counts and rugged scotsmen.
(Base 03 / +01 Part)
Banishment of Lifes Excess
R : Touch / D : Mom / T : Part
Level 15
PeCo
All excess fat is removed from the targets body.
As Perdo Magics cannot make a thing a better example of itself ,
the target is left with many folds of loose skin.
A Muto spell to change the appearace while the body sheds the excess skin naturally may be required.
A Creo spell doing the same thing will require a ritual spell and Vis use.
(Base 05 / +01 Touch / +01 Part)
If Base 05 can destroy a corpse , then it should be able to destroy something like body fat.
As the target loses all body fat , they can possibly be considered the equivalent of lightly wounded ,
because some body fat is needed for physical comfort.
Perdo cannot make something a beter example of its kind. Perdo destroys and whithers.
I think that this spell as written perfects the body and belongs as a creo spell (which would need to be ritual to be permanent).
I could imagine a perdo spell that cuts skin growths and the like off of a target and leaves them bleeding from a myriad of tiny wounds that when they heal, may, if the target is lucky, leave the target a more attractive person than he or she was prior to the wounding.
The base of this spell only allows for superficial damage , not actual wounding.
I agree with your description , but had forgotten to write something to that effect.
Again , i would use a MuCo spell to alter appearance while the target healed naturally.
(probably basic first aid for all the minor cuts as well)
Unless the growths and blemishes were bought as a flaw , then this spell should remove them.
Yes , the removal does improve the targets looks , but does not perfect the body.
A Creo Ritual spell could improve the target in this manner ,
but what level guideline do you use?
I agree with Erik that it should be Creo. I don't think you should view this from the surgical/dermatological point of view.
So does this spell cause superficial damage or not?
I could equally make a spell that destroyed grunge under finger and toe nails ,
which would improve the target cosmetically.
Destroying ear wax would aid hearing somewhat.
Perdo away unsightly mucous to clear sinus , even if temporarily , to aid breathing.
I could go the Rego Craft route with Chirurgy to remove small unsightly bits from the body.
No. "Removing imperfections" wouldn't count as "damage".
None of which is actually an integral part of your body.
Yes, you probably could.
As i normally don't get to practice making spells ,
i find the Guidelines and published spells a little unclear at times. 
I was trying for an effect that caused minor damage.
That it might improve looks was a side effect.
I don't really either, which is why you'll find me criticizing other people's spells rather than propose my own.
They are often very vague. "Direct the flow of bodily energy" ... 
Try the other way round: cause a bunch of tiny cuts which will leave scars.
Well, if someone had a third arm, you could probably Perdo it, and it would help. 
But removing skin imperfections really comes under "making the skin perfect".
It's all Abe's Fault. 
A Pillar of Sand by Day
R : Voice / D : Diam / T : Ind
Level 15
CrTe
Creates a pillar of sand : 01 pace diameter and 12,732 paces high.
(10,000 cubic paces)
(Base 01 / +02 Voice / +01 Diameter / +03 size)
While the full height of the pillar will only be momentary ,
it should fall with enough force to stun those nearby.
The caster can either ward himself against sand ,
or cast with zero penetration , as he is likely to be caught in the fallout.
Situational modifiers for very windy conditions
or placing the pillar over cellar doors and the like may apply.
+Size can get very scary very quickly. 
+1 for the rather extreme shape? How high is the lunar sphere supposed to be anyway?
A Pillar is not an extreme shape , imo.
As for how high the Lunar Sphere is , i dinnae ken. 
I'm referring to the aspect ratio.
I know astrologers tried to find out how high were the heavens, but I can't remember what kind of values they came up with. That's the worry I have with the height of your pillar of sand. 
I am sticking to the base of 01 pace thick.
How much can we use the aspect ratio before it becomes extreme after all.
Plus the height is only momentary (even if not by spell design).
It would take the sand at the top approximately 48.7 seconds to fall to the ground.
(if the Aristotelian physics work that way)
Wikipedia tells me nowt on this.
Mt. Everest is 29,028 feet high (9676 paces)
Not sure what the tallest known mountain is in Mythic Europe.
If a pillar spell makes something that would normally go beyond the Lunar Sphere ,
presumably it just stops at the Limit.
Sphere of Sand
R : Touch / D : Diam / T : Ind
Level 15
CrTe
Creates a sphere of sand : radius of 28.8 paces.
(100,000 cubic paces)
(Base 01 / +01 Touch / +01 Diameter / +04 size)
For some reason when reading this I had the image of 2 magi playing various sports, such as hand ball or air hockey, with a magical "ball" that gets repulsed by their parma so they dont need the normal paddels/bats/ect
