Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
You might know this ingredient as Ethyl Ascorbic Acid, a more stable version of ascorbic acid.
Like other types of vitamin C, this ingredient has many benefits including reducing wrinkles, skin soothing, dark spot fading, and fighting against free radicals.
3-O-Ethyl Ascorbic Acid interferes with the process of skin darkening, helping to reduce hyperpigmentation. It also encourages the skin to produce more collagen.
Once applied, 3-O-Ethyl Ascorbic Acid is converted to Vitamin C deeper in the skin's layers. This process is slow but makes this ingredient more tolerable for skin.
The optimum pH range for this ingredient is 4 - 5.5

I'm honestly not sure what is in this that is supposed to treat acne besides Niacinamide, which I've come to suspect my Show more
I’m not sure if this did anything in terms of lightening acne marks but it may have contributed to one of the worst breakouts of my life. It has a mild citrus scent and is a gel that absorbs well without stickiness but nope it doesn’t work.
