So I'm quite worried about the items in addition to those mentioned above.
Therefore, I would like to ask for advice on which items should be adjusted in this formula, how many % to avoid irritation around the eyes when using it all the time?

Do you want me to cut or add any % ingredients to improve performance?
3. In this formula, how much must I adjust % of any items to remain? so it can be mixed
4. It is expected that you will get a light gel texture, not heavy and easy to spread.
5. Suppose if you want to use Ferulic Acid instead but dissolve in hex or BG, what proportion will you use to dissolve FA?
