Step 1: Clean the skin thoroughly before applying this product
Step 2: Cover the entire affected area with a thin layer one to three times daily.
Precautions: Avoid eye area. Because excessive drying of the skin may occur, start with one application daily, then gradually increase to two or three times daily if needed or as directed by a doctor. If bothersome dryness or peeling occurs, reduce application to once a day or every other day.

Efficient and non irritating serum
[I received this product in exchange for my honest review] I've been using the La Roche-Posay Effaclar Duo+M for a few weeks now, and I can honestly say it's one of the better spot treatments I've tried, especially for stubborn, hormonal breakouts. The texture is lightweight, almost like a gel-crea...

Overpriced and overrated
I recently got gifted this product in exchange for my honest opinion. I was so excited to use a product from this brand as I heard many great things about them. After using this product for 2.5 weeks now, I can best describe it as overpriced and overrated. While it is not a bad product by any means,...

Good for drying out breakouts
[I received this product in exchange for my honest review] This is a good product for acne prone girlies. It dries out the affected area without just completely stripping the skin. Do keep in mind that it's supposed to be a thin layer over the affected area rather than just a spot treatment- I think if you use it correctly it would work well for you!

Would not purchase
[I received this product in exchange for my honest review] Did not work at all! I was very disappointed as I've used their other acne products but this just did not do the trick. I tried for atleast 3 months but my spots never faded and it never even affected them.
A must have
[I received this product in exchange for my honest review] Very helpful for those stubborn breakouts. As someone who suffers with cystic acne and hormonal acne this is now a must have in my daily routine.
It is great for any age
This product was very great for acne I am 48 years old and I still get acne once in a blue moon my daughter is 16 and she still getting at me and it worked very well on both of us thank you Ulta for this great product I will be buying again.
