Another points;
vitamin C needs pH of 3.5 for effective 
other stable form of C needs pH of 5 to 6

[Dtdang]

Use ethyl ascorbic, the stable form of vitamin C. Easy to formulate 

[Dtdang]

thanks all

[Dtdang]

Thanks @Belassi

Here are my thoughts:
rose hip oil 2%

Hydroxystearic acid 0.5%

Castor oils 0.5%

Shea butter 0.5%

Squalane 1.5%

C13-15 1.5%

any thing wrong?

[Dtdang]

I am against any ingredients that are not healthy to us 

[Dtdang]

Ethyl ascorbic

@ngarayeva001
i agree with you that some eo oils are bad for skin
but, some of them are good. 

So my idea is to identify the one is good for oil.
but, it seems that it is not easy tasks.

@LuisJavier 
I have very success on lighting cream when I combine: vitamin b3, alpha arbutin, vitamin c together. But , be attention on pH .

@ngarayeva001, I always want to see the proof bc Tea tree oil reduces acne. I saw the result on 40 people who tried out.

I surprise that there are no research information about EO.
I have used lavender oil with only 0.75%. 
Information of lavender oil in webmd: 
https://www.webmd.com/vitamins/ai/ingredientmono-838/lavender

I plan to open a new topic on EO 

[Dtdang]

I used in mine is 0.5%

It thickens the water soluble ingredients 
I also used cetyl alcohol for thickening oils phase ingredients 

[Dtdang]

To all experts on essential oils. 

I am very new on essential oils. Please 
share your experiences and any documents that we can trust.

thanks all for inputs 

[Dtdang]

I had same problem like that
here what I do: put xanthan gum onto oil phase and heat to 70C
will take care the problem.

[Dtdang]

I have question:
1) all ingredients that are water soluble are mixed well with stirrer
2) all ingredients that are oil soluble are mixed well with stirrer.

 Now 1) and 2) are put together for emulsion 
Question: should I use stirrer or homogenizer?

thanks in advance

Only castor oil 0.5%, the rest is the same.
I added 0.5% of castor oil bc ricinoleic acid
