Hi

whats a good PH for a eye serum ? Since eyes have a normal PH of 7 (while skin is under 5) is 6.5PH a good target ?

Is it supposed to be applied around the eyes or inside the eyes?

If around the eyes then pH ≤4.8 is better.

I don’t know about inside the eyes.

It’s a serum for puffy under eyes, my concern is that at ph 5 it will sting the eye if some material will get to the eye

The pH of skin…varies with different areas of the body… Your arm, armpit, face, legs, groin…all have different skin pH’s.

That being said…the area directly around your eye, is higher than most. Hence adjust accordingly.

I assume you are not putting this IN your eye.

I typically formulate at 4.6 to 4.8….but not with the eye cream.

If it goes into eye there are more irritating ingredients like preservative, chelating agent and fragrance & other ingredients in your product than pH.

You should avoid it going to your eyes.
