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!

La Roche-Posay Effaclar Duo (+) Dual Action Acne Treatment 13 ingredients
I don't really have a lot of cystic acne or large noticeable skin issues so honestly, I didn't see very obvious results or large differences. But, however, I have noticed my skin feeling smoother, the skin tone feeling more even, and a lack of newly developed acne after using this every day for 3 weeks. This product is a good preventative measure and overall well formulated however you have to Show more
My holy grail for pimples, any red pustules gets flatten down, reduce and disappear with this.
