Whitening toner/serum for face
hello everyone! Happy to join the form.
I did a toner for whitening and when I apply it I feel a burning/warming sensation, is this normal or should I remove lemon peel?
My formula is as follows:
Neroli water 76%
Hylournic acid 1%
Aloe vera 1%
Witch hazel 1%
Kojic acid 3%
Licorice 7%
Niacinamide 5%
NAC 2%
Lemon peel bioferment 2%
vitamin E 1%
Preservative 1% -

What preservative do you use? Sorbic acid or potassium sorbate can give flushing-like sensations like you describe.
Neroli and witch hazel can be potential irritants.
7% licorice is a lot by the way! That toner must be quite dark in colour!
With NAC you mean NAG? -
Kojic acid is unstable and also causes some inflammation. Hence the need for a sunscreen and other measures. These are not harmless actives.Kojic acid Dipalmitate is more stable but oil soluble.Niacinamide is also an irritant. -
On the Reddit sub r/SkincareAddiction, there is a small group of people there who experience allergic-like reactions to aloe vera (burning, stinging, redness, even a rash). Sounds bizarre, as it is supposed to be such a soothing ingredient - but, could be a possibility that you are similarly “allergic”?
(These folks were using either raw aloe gel directly from the plant, or low-processed products [ex: aloe gels with very few added ingredients]).

@Microformulation Is Niacinamide really an irritant at 5%? I have only read that it is potentially irritating at higher percentages, such as 10%. Is there is some information I am not aware of? Also, isn’t it only Niacin (not Niacinamide) that causes skin flushing?

@noraf Did you check the pH of your final product? I’d be curious to know what you found, if you did.

It is not unheard of to get some irritation at 5%. I will look for the citation later, bi it is even more pronounced in person’s of Asian descent.
