I need help with face serum formulation

A quick abstract on the size of pores:TL;DR
CONCLUSIONS: Enlarged pore sizes are associated with increased sebum output level, age and male sex. In female patients, additional hormonal factors, such as those of the menstrual cycle, affect the pore size. -
@Sibech
Anything on cosmetics that change pore size permanently? -
@Doreen, I agree that size of pores is generic, but you actually can make them look smaller (let’s say make them look their smallest) with Niacinamide (it’s not a permanent effect). It’s one of the actives that actually works. I will try to find a study.

@Mrs_ditdut, you excluded all gel makers and the serum will be thin as water. Other ingredients are ok. I don’t want to confuse you and I am not insisting that my way is the right one. Xantham will do the job and maybe you should try it to see how it feels. I remember how demotivated I was when my products didn’t feel like “commercial”, that is why I am saying that xantham gum might be disappointing. Also, experts are not “against” HA, it is just outrageously expensive. What I would recommend again, get a 10 gr pack of high molecular weight HA. It will last for some time (for personal use). You should try the ingredients yourself. It’s all about experimenting. My personal opinion is that low molecular weight HA is a waste of money. The high weight is better because it can be used as a gel maker for serums. Another good option is Sepimax Zen (can you get it?), but you would need to add humectants. It’s good to have glycerin, butylene glycol and propanediol in your stock.

2% tea extract will make a highly coloured product. 0.2% would be more appropriate. It will be a pink colour at the correct pH range but will slowly oxidise to beige.

@Doreen not at all (to my knowledge there are not even surgical procedures, I may be wrong though) - your pores have a life of their own.But due to a reduction of sebum secretion, niacinamide (for instance) can reduce visibly pores as @ngarayeva001 mentioned. Other compounds which may reduce sebum secretion would likely also work, including polyphenols, plant sterols, topical retinoids, L-carnitine (of the top of my head).

Sorry to deviate a bit from the question but does HA dissolve and turn to gel in glycerin? Also LAA?
-
@Majman - I’d suggest you start a new discussion for that question.

Ok
