As titled. I've seen Retinyl Palmitate, Retinol, Vitamin A, Tretinoin, Retin A, etc etc
I might have left some out but this is pretty much what I've seen. So I'm very confused as to all these Vit A derived products. What're the differences? I wanna try it as everyone said it has great anti-aging properties. I'm 29 this yr and I would like to prevent aging or at least slow it down. Which is the best one to try for a newbie? I don't want red peeling skin though as my skin seems fine right now.
Also, would it help at all if I just use a serum that contains Retinyl Palmitate in it or just Vit A? Thanks so much!  |

I am on the verge of buying a tretinoin but don't know which one. Some are outrageously expensive but do they have something special that the others don't to justify the price?
I don't want irritated red skin but is that simply a matter of using less? Should I just buy the cheapest one? Have you tried one but found another to be better?
I have a Rx for Renova and Refissa. Can they be used for Tazorac or Avita or must it be generic Tretinoin in the same strength? |

| btw, you still need to look at the concentration of the ingredient b/c same ingredient for example retinyl palmitate but in low vs high concentration does make a difference. |

the conversion of Retin-A or Retinalderhye and Retinol are as follow
Retinyl palmitate <=> Retinol <=> Retinaldehyde => Retinoic acid
It takes two and three metabolic steps, correspondingly, to convert retinol and retinyl palmitate to retinoic acid. The overall rate of conversion of retinol to retinoic acid is low and that of retinyl palmitate is lower still. Therefore a relatively large amount of retinol and even larger amount of retinyl palmitate needs to be delivered into a cell to boost retinoic acid levels and produce clinically meaningful effects
The products with high concentrations do exist but may still not deliver the purported benefits for a number of reasons. In particular, a product with highly concentrated retinol may cause skin irritation, especially in people with sensitive skin. Highly concentrated retinyl palmitate is less irritating than retinol (at equivalent levels) but is also less effective. Therefore i choose the middle step.
but using the retinol molecular film, since the molecule is very small; therefore more easy to absorb and less irritation.
