How to use vitamin C products?
Vitamin C serum is usually recommended to use in the morning  
because it is an antioxidant and will protect you throughout the day. 
But in the evening it is also possible, especially if the remedy is 
unpleasant.Vitamin C can be used every day.
Do I need to protect myself from the sun when using 
Vitamin C Serum on Face?
If you are concerned about pigmentation and age-related changes, you 
should always use sunscreen gel, regardless of whether you use acids or 
not.
Whether you are using retinol or not. I suppose it worries you if you've 
read to this point. But if not, you can only use it from May to October 
when you go outside. You can also find vitamin c in fruit and vegetable 
whichboost the immune system with intake of vitamins and minerals.
If the concentration of vitamin C is low, then, as a rule, it does not
provoke anything in the skin that can enhance the effect of 
ultraviolet radiation.
If it is higher, then it can already exfoliate a little and increase 
sensitivity, and here it is better to protect yourself from the sun 
more thoroughly.
What is it like?
Vitamin C in cosmetics like Vitamin C serumcomes in many different 
formulas, but the most interesting from the point of view of proven 
effectiveness is ascorbic acid.
In combination, it is called ascorbic acid or L-ascorbic acid. All the 
properties of vitamin C help free radicals.
Most often, the Best Vitamin C serum for face is like water soluble 
vitamin. Sometimes it is encapsulated in wax, phospholipids, and some 
other components, and then the agent is usually no longer like water.
Here are products in the form of pastes, usually based on many 
silicones. I personally love silicone and there is nothing against them, 
but there are a lot of people who hate silicone.
Such pastes are usually unpleasant, powdery felt, and absorbed for long 
periods of time to irritate the skin, but they are stored much longer 
than those that have dissolved ascorbic acid in water.
What other forms of vitamin C are there?
The most common forms are
Ascorbyl Glucoside: Water-soluble form. This is perhaps the second 
most studied form of vitamin C after ascorbic acid. But there is still 
not much data about her. It is definitely known that it is stable and 
penetrates the skin.
And after penetration, it is transformed into ascorbic acid. But what 
percentage of it is eventually transformed is not very clear. But this is 
perhaps one of the best forms to look out for if you want to start 
using vitamin C but for some reason don't want to start with ascorbic 
acid.
Funds with it are usually not too expensive, unlike the next form.
Tetrahexyldecyl Ascorbate (THDA): Fat-soluble form. There are few 
funds with it, but it is believed that it works almost as effectively as 
ascorbic acid, or even better.
In part, it is considered more effective due to the fact that it is fat- 
soluble, and fat-soluble substances penetrate the skin better than 
water-soluble ones. Because the skin's protective barrier does not 
allow water to pass through.
There is research confirming that this form does indeed penetrate the 
skin and is indeed transformed into ascorbic acid. Moreover, it 
penetrates 3 times better than ascorbic acid, even when its 
concentration is much lower.
A remedy was used on half of the face, which had 10% ascorbic acid 
and 7% THDA, and the results are very good. But one can hardly draw 
any conclusion about THDA here.
Here they used a cream with 30% THDA in combination with a serum 
with retinol, and there were also good results, but, again, there is 
nothing to say exactly about the effectiveness of THDA.
I personally really love this form (or at least the products with this 
form), I hope to make a serum for DTMSkin with it. I think this is a very 
cool form for people with dry skin and for those who like rich products. 
But this form is quite expensive, so you won't find cheap serums with 
it.
Sodium Ascorbyl Phosphate (SAP): A very common water-soluble form 
of vitamin C. In addition to the above properties, it has anti-acne 
properties.
By itself, it does not really cure, but in combination with classic anti- 
acne ingredients, it works great. So it makes sense to pay attention to 
products with this particular form if you have problem skin and are 
looking for vitamin C. It is effective in low concentrations.
Magnesium Ascorbyl Phosphate (MAP): Also a very common fat- 
soluble form. Also not well researched. And I found one study about 
that. That it can also be useful for acne, but only as an adjunct to 
general therapy, and not by itself.
However, there the study was carried out in vitro, so I would divide 
such conclusions by ten. But you can always try, why not.
Retinyl Ascorbate: This is a very interesting form. It is a combination of 
retinol and ascorbic acid. It is assumed to have properties of both, but 
again, there is no research.
AscorbylTetraisopalmitate:A very common form, it is often 
recommended for very sensitive skin. It is believed to penetrate the 
skin very quickly. There is confirmation that it penetrates the skin and 
cells, but only in relatively high concentrations.
I will not describe the rest, because I have not found a single product 
with them, where they would be the main ingredient. But, I think you 
get the idea of how to pick out something related to vitamin C in the 
composition.
