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. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

Retinol is a form of Vitamin A and proven to help with anti-aging.
It promotes collagen production, increases new cell turnoever, and protects your skin as an antioxidant.
Retinol boosts collagen production and increases cell turnover. This makes retinol effective in removing wrinkles, fading dark spots, and reducing the appearance of pores.
Retinol is less effective when exposed to sun. Be sure to look for appropriate packaging to keep your retinol potent.
Using retinol and retinoids will increase sun-sensitivity in the first few weeks of use. Though studies show retinoids increase your skin's natural SPF with continuous use, it is best to always wear sunscreen and sun-protection.
We recommend speaking with a medical professional about using this ingredient during pregnancy.
Retinol may cause irritation in some people, so be sure to patch test. Experts recommend 'ramping up' retinol use: start using this ingredient once a week and work up to using it daily.
