Nutrition ⇒ Skin and Collagen

[NewLifeScience]

Wasn't sure which main category to post this in...

I am aware of the claims about hyaluronic acid which either boosts collagen levels in our skin and / or joints, retains moisture in our skin or both.

But i am wondering if anyone here knows about how NMN or other products can boost collagen levels, or bring them to levels of a younger version of ourselves. I am 52 and just starting to notice certain changes in my face... the dreaded droop approaches.

Keen to see if anyone else has input on this.

I've been reading posts by Fred the dietitian and it seems that Vitamin A and Retinol are our friends

We should perhaps have a "Skin and hair"-section in the forum for simplicity. Tretinoin or retinol is for skin repair (collagen, elastin and GAGs). Tretinoin is also sometimes used in hair-preservation formulas as a penetration enhancer for the drug minoxidil.

I've read in the past that hyaluronic acid is good topically - here's a quick article about it:

I don't know if it's as good as retinol or if it's just a "buzz ingredient", though...I'm not much of a skin care product person, I just stick to good old sunscreen and a hat!

Hyaluronic acid can't penetrate skin. It can only moisturise the outer layers. That is why HA fillers are injected into the dermis.

But retinoids can turn on the genes, HAS, for HA production along with collagen and elastin in the dermis.

Supplementing vitamin C can increase the synthesis of type I collagen, the most abundant collagen in the body (DePhillipo 2018).

Fascinating, cheers Fred! Quick question...in regards to retinoids, I've read in the past that it was not advised for pregnant women to use retinoids - what is the main reason for that?

The truth? Fear of unfounded lawsuits from patients. Oral high dose vitamin A is teratogenic and can cause birth defects.

There's been zero cases of a retinoid cream causing that. It simply cannot raise the level of vitamin A in the blood high enough, barely at all.

So. The American justice system is the short answer.

Ah, very interesting, thanks Fred!

Are you referring to oral vitamin c or a vitamin c serum?

I'm not Macrobian. Both stimulate collagen synthesis. But topical vitamin C gives you more local protection against the solar radiation in daylight that ages the skin. You get more vitamin C in the skin topically than orally.
