I'm trying to make a DIY facial serum for my personal use and this is what the formula looks like:
|Tea tree oil
What I'm trying to achieve is to:-
Sooth the skin
Improve skin appearance
Encourage skin health
Now my questions are:
1. How good is this formula? any suggestions or comments to improve it?
2. Do I need to include any emulsifiers?
3. I have some concerns of using citric acid to adjust the pH because am using sodium hyaluronate, I'm not sure if there will be any reactions between both materials or not? am aiming to pH 4-6
finally, this formula still on paper, I haven't produce it yet.
