Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.
You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

It is a:
- Humectant, drawing moisture into the skin
- Emollient, helping to soften skin
- Solvent, dispersing and stabilizing formulas
- Preservative booster, enhancing the antimicrobial activity of other preservatives
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
Learn more about Butylene GlycolEthylhexylglycerin (we can't pronounce this either) is commonly used as a preservative and skin softener. It is derived from glyceryl.
You might see Ethylhexylglycerin often paired with other preservatives such as phenoxyethanol. Ethylhexylglycerin has been found to increase the effectiveness of these other preservatives.
Allantoin plays a role in soothing and moisturizing the skin. Because of this, it is often added to products with strong active ingredients.
Some studies have shown this ingredient can promote wound healing with higher concentrations.
Allantoin is derived from the comfrey plant but produced synthetically for cosmetic products to ensure purity.

For the short time that I've used this serum Ive grown to love it. A great serum for acne prone/irritated skin. This serum has helped the redness in my face as well as my post acne marks almost clear completely. Highly recommended.
This serum is VERY VERY POTENT the 5% difference from the AZ 10 is a real difference, I use it as a spot treatment for now, it literally kills any inflamed acne overnight and makes it go away in 3 days, worked for whiteheads, pimples and even under the skin bumps and cysts that I felt coming to a head went back down after applying for 3-6 days. I don't know I will try and see if I can work up to Show more

I’ve been using this product for the past couple of days and noticed that it’s making my skin break out with a few small closed comedones and pimples on my cheeks and nose. I highly doubt that my skin is purging since this serum contains ethyl ascorbic acid which is a more gentle alternative to L-ascorbic acid and vitamin C isn’t supposed to make the skin purge. I’m assuming the breakouts were Show more
*This is a review for both Vitamin C Serums* This vitamin C serum for sensitive skin is a good product but didn’t have a good experience with the boosting vitamin C serum. Was applying the orange vitamin C serum for just 2-3 days straight and suddenly I started getting acne on my chin, forehead , which I never got acne on those places. Did not feel no irritation while applying the vitamin C , but Show more
