hello,
Well, I ordered Zinc PCA and put it in the factory's serum formula. that are normally sold to try to make a formula to reduce acne especially
It appears that those who have tried it report that they have more inflamed acne without changing other extracts at all. Just reduce the % in water and add Zinc PCA to 1%. I would like some advice as to what might be the cause in the formula:
formula:
1. Water 81%%
2.Niacinamide 10%
3. Isopentyldiol 5%
4. Sodium Citrate 5%
5. Ethoxydiglycol 1%
6. Zinc PCA 1%
7. Sodium Hyaluronate 0.3%
8. Phenoxyethanol (and) Triethylene Glycol 0.5%
9. Hyaluronic Acid 0.3%
10. Hydroxypropylmethylcellulose stearoxy ether 0.1%
