I don't want to alarm everyone, but there was talk about aloe vera and glycation on the skin interactive board a while back.
I didn't pay particular attention at the time because i wasn't using any products very frequently with very much aloe. The reason I am interested now is because my new favorite sunscreen (Devita Solar Protective Moisturizer 30) has aloe vera listed as the second ingredient.
I haven't researched extensively on this but have read some articles here and there.
Here is an excerpt from http://forum.lef.org/default.aspx?f=38&m=17177 :

Aloe vera improves wound healing and inhibits inflammation. Since mannose-6-phosphate is the major sugar in the Aloe gel, the authors examined the possibility of its being an active growth substance. Mice receiving 300 mg/kg of mannose-6-phosphate had improved wound healing over saline controls. This dose also had anti-inflammatory activity. The function of mannose-6-phosphate in A. vera is discussed.
Besides glucose, other reducing sugars, such as mannose, react with proteins to form advanced glycosylation end-products (AGEs), that are active in cross-linking collagen and elastin, the process that causes skin aging... |
I admit i don't really understand the sciency part of this and was wondering what everyone's thoughts/interpretations are.

I'm kinda confused - because those 2 paragraphs don't seem like they make sense together? Wound healing is normally associated with anti-aging products (and aloe is long believed to be good for the skin, and that seems to support that).
And mannose and mannose-6-phosphate although they may sound similar are quite different molecules.
Mannose:
http://en.wikipedia.org/wiki/Mannose
Mannose-6-phosphate:
http://en.wikipedia.org/wiki/Mannose-6-phosphate
My guess is both statements are right - mannose-6-phosphate being beneficial, while mannose isn't? |

ok so as far as that says it is an internal process and it doesnt seem that aloe would do that at all ....' Amount of Caloric Intake – “age-related
accumulation of AGE is more closely related to
[the amount of] caloric intake ...than a specific
dietary carbohydrate” present in the diet.'
interesting! and yet another reason to cut down on sugar!
damn!  |

Good enough for me - thanks for posting that. So in the review it basically says Aloe Vera is anti-glycation due to all the other beneficial components in it. Now I have even more reason to use aloe.  |
