Hi, I am having a problem with my face pads darkening after abou two weeks. I have done quite a lot of research, and even changed some of the ingredients. I used to use aloe juice, but switched it to a high quality organic freeze dried powder. I look into each ingredient, and I saw one article about how the vitamin c could be the cause. The formula ph is 3.5. Here is the ingredient list, Organic Whole Leaf Aloe Barbadenis (Organic Aloe), Organic Salix Alba Extract (Willow Bark), Organic Witch Hazel, Organic Orange Blossom Water, Vitamin C (L-Ascorbic Acid), Glycolic Acid, Vegan Hyaluronic Acid, Non-Synthetic Vitamin E (D-Alpha-Tocopherol).
If the vitamin c is the cause, do you think replacing it with Kakadu plum extract would be a good idea? I have read that it is very high in vitamin c. I also looked into using sodium ascorbyl phosphate, but it has an optimal ph of 5-6, so I'm not sure if it will cause darkening to occur as well.
Thank you for any help! I really appreciate it!
