Unless is magic, i think is a fake… 
They dont give any details about the product ingredients. The pictures are not clear. Also, without pigments i dont know how that white cream can even the skin color and hide the imperfections.
I think is too good to be true..

Hello,
Maybe you can use Squalane.

Hello Perry and everyone!
My name is Andreea, and i am very passionate about making my own cosmetics, for my personal use, even though i do not have background in chemistry. 
Happy to be part of this forum!

Hello!
thank you for the reply, Paprik!

I knew the Timeless ingredients list, and from their order, yeah…they used less Polly 80 than me… Maybe 1:1 with Vitamin E…
When i did that, the solution became milky and while resting, tiny oil dropplets gathered on the surface. Still milky until today, after more than one week. The same with the sample of 1:4 (vitamin e, polly80), with the difference that with this ratio, the oil doesnt separate.
Maybe i had to use just 4% of Polly80, even if the solution will stay milky 🤔

I am using many other actives on my skin, inclusive tretinoin, so i didnt want to start directly with 20% vitamin c. 
By the way, this serum that i did is not stinging my face at all, and after 10 days is still clear like in the begining. No sign of oxidation 😁.

Here a picture with samples of Vitamine E and Polly 80 in different ratios (after 10 days).
Ratios: 1:4, 1:10, 1:1

Hello! Thank you for your replies! I appreciate them so much!

I will try to explain a bit why i did what i did. Might not be the right decisions (due to lack of background in chemistry), but i am experimenting and learning ….

The reason why I chose to use 20% PG is because i know that above that concentration, in an aqueous solution doesnt support bacterial growth, so is contributing to the preservation of the formula. Secondly, i needed to disolve the Ferulic Acid in. Also i thought that maybe will help Vitamin C to penetrate into the skin. I red that it can be used in cosmetics/drugs at an even higher concentration, and that not everybody is allergic or irritated by it. I tried it on my face and i didnt have any reaction, but yes, maybe is too high the concentration and in time can cause problems for the skin…

Before using Poly80 in the final product, i did separate tests, mixing oil with Poly 80 and distilled water at different ratios. The clarity of the solution wasnt influenced by the pH.
So first I reached clarity at 10% with distilled water, and i kept same ratio for the final product that has acidic pH, and the clarity remained the same.
Again…if is too much 10%, probably i should find a better solubilizer… Or to repeat the tests.

I chose 15% LAA, because i red that it is efficient above 8-10% and over 20% can be irritating, so i thought that is better to stay in the middle.

Ngarayeva001, I looked over the L’Oreal’s patent, and i understood what you ment when you said that i need more glycols…. Problem is, that i barely found PG where i live. If i want for example Ethoxydiglycol, i have to order from another country (and probably i will). Another reason why i used PG that much.
