Ingredients Explained
These ingredients are found in both products.
Ingredients higher up in an ingredient list are typically present in a larger amount.
Dimethicone is a type of synthetic silicone created from natural materials such as quartz.
What it does:
Dimethicone comes in different viscosities:
Depending on the viscosity, dimethicone has different properties.
Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions about the viscosity.
This ingredient is unlikely to cause irritation because it does not get absorbed into skin. However, people with silicone allergies should be careful about using this ingredient.
Note: Dimethicone may contribute to pilling. This is because it is not oil or water soluble, so pilling may occur when layered with products. When mixed with heavy oils in a formula, the outcome is also quite greasy.

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!

I used the Duac Gel for years until my pharmacy ran out of stock and replaced it with the InfectoPharm Clienzo Gel, which contains the same ingredients: Clindamycin 10mg/g and Benzoyl Peroxide 50mg/g. It dries out pimples quickly and has saved my skin countless times. Thankfully, I don’t need it anymore because my skincare routine is so effective that I usually don’t get pimples. It ruined so many Show more
Very strong cream, but it’s medication in the end.
I started using it after intense respiratory infection that wreaked my immune system, and i got large, painful cystic acne.
I apply it at night, after face wash, leave it for 20-30 minutes and then follow up with hydration tonic and moisturizer. It’s important to use sunscreen every day when using it.
First few nights i used a larger Show more

It’s a great starter product with azelic acid.
The price is relatively cheap, the tube will last you long time and it delivers what it should - azelic acid.
However, despite people’s suggestions here I personally would not use it as last step. It does not say it on their homepage but azelic acid has usually low ph. Thus adding it as last step might cause damaged skin barrier on a long run! Show more
Hate
I have rosacea and perioral dermatitis so I thought this would heal my skin but I HATE it. It’s silicone based so it dries matte and you can’t apply sunscreen or any makeup on top. You also can’t reapply because it’ll start pilling. Don’t even think about touching your face after putting this on because it’ll pill. It also stings really bad which is the opposite of what you need for rosacea Show more
