External:
Photoprotection from ultraviolet a and b –
Vit c is Antioxidant, uv light can cause ros, vitamin c gives them electrons and oxidants don’t steal electrons from your skin.
Zeus is vitamin c, throwing the bolt electron to oxidant enemy and keepig them at bay.
Counters hyperpigmentation –
Permeation:
Lower the ph and it raises the charge to more positive and now it can penetrate the skin. Every skincare product at ph 5 or higher does not make vitamin c penetrate the skin.
Needs to be 3.5 or lower.
Ascorbyl-6-palmitate vitamin c, Magnesium ascorbyl phospate (map) are lipophics
It’s important because cells shells are made of lipids, hece vitamin c is attracted to their exteriors
Less than 8% doesn’t effect, above 20% does not give more effect, sweet spot
Internal
How does it work
Promote collagen synthesis – different enzymes making the collagen, vitmain c intervenes and raises the Mrna of collagen making enzymes.collagen is important for wound healing.

Crusade in favor of vitamin C
We lost the secret weapon of self producing vit C
1.gorillas are able to make their own VITC at 2.3 grams/day (tablespoon), mammals in general make vitamin c from glucose.
Important.
Important to consume fresh supplies of it because the body cant store it.
Body ph is 7 so it’s degradating quickly.
All the immune system needs ros to distroy viruses and bacteria, so antioxidants aren’t the only way to go, balance. Vitamin c sacrifices itself but for tha army of the immune system
If we supplement it job of immune cells becomes harder
With cooking vitamin C gets distroyed. That’s why eternal diet was specifically formulated.
History
- 1850 Lemon juice cures scurvy, 1700 sailors had it. Due to low collagen synthesis.
- Something interesting
- Something informative
Lipid peroxidation is the oxidative degradation of lipids. So, it is a bad thing, and VitC defend against lipid peroxidation which is good.
Collagen got some amino acids which are hydroxylated. Different collagen types got different hydroxilation content. It doesn’t make it stronger or weaker it’s just a characteristic. But every collagen needs hydroxilatio, VitC helps, so it’s a good thing too.
