Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Skin Conditioning, Solvent

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!

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.

Antimicrobial, Antioxidant

Ferulic Acid is a plant based antioxidant. By fighting free-radicals, ferulic acid can help reduce the formation of fine lines and hyperpigmentation.

When used with Vitamin C, Ferulic Acid has shown to prevent Vitamin C from breaking down. In other words, it acts as a stabilizer.

Ferulic Acid is sometimes used to preserve food. Foods containing Ferulic Acid include: oats, rice, eggplant, citrus.

In medicine, Ferulic Acid is being studied for helping with diabetes, Alzheimer's, and cardiovascular diseases.

Would repurchase, have repurchased.
Fantastic and effective vitamin c serum for acne prone skin. The 10% is more suited for reactive skin. I hate that it works so well for overall skin health. It made my skin just look more … balanced? And it also worked synergistically with azelaic acid to fade my dark spots.
