"My other recommendation for brand in the adapalene 0.1% category is definitely the La Roche-Posay Effaclar Duo. This is similar formula to adapalene from different gel but it's a little bit gentler base with that soothing thermal water from La Roche-Posay."

"La Roche-Posay Effaclar Duo contains 5.5% micronized benzoyl peroxide formulated in a more gentle way along with lipohydroxy acid, which is a more gentle form of salicylic acid that can also help to exfoliate. It's in a light lotion texture that's very easy to apply, absorbs very quickly with minimal residue."

"This is a solid product, only 30 something bucks you can get at your local store like say at Target or Amazon. It's a really nice product to consider to add to your regimen. The only downside would really be if your acne is out of its league, you've got to go see a dermatologist. It's not a magic bullet. If you have deep cystic bumps, that's something you'd need to see a dermatologist for. This is good for superficial acne, but it's a great product."

"I used to use the La Roche-Posay Effaclar Duo and I found that it packed such a powerful punch that it really destroyed acne but then left me with a kind of a red ring around that sometimes is so bad that I'd have to use a topical corticosteroid to get it to go away which you're not really supposed to use on your face."

Dermatologist Explains: How to Mix Skincare Ingredients

"If you had a benzo peroxide spot treatment say the La Roche-Posay Effaclar Duo with LHA plus benzoyl peroxide I would not combine that with the retinoid. I just keep that separate."

"The luros effaclar would be a nice option and then apply your retinoid whether it's prescription tretinoin over the counter retinol or adapalene and then apply your moisturizer always apply a moisturizer after your retinoid"

"This is a hero product from La Roche-Posay that I've been recommending for a while now. It's got 5.5% benzoyl peroxide, which is a wonderful ingredient for acne. It's anti-inflammatory and targets the bacteria that causes acne, so it will help fight off existing breakouts and prevent breakouts in the future. Unfortunately, it's very drying and it does bleach fabrics if it comes in contact with your skin and can bleach your hair if it comes in contact with your hair."

"This reminds me of the La Roche-Posay Effaclar Duo with the benzoyl peroxide 5.5% at $32. Benzoyl peroxide is good for acne breakouts but it can be drying though."

"I love La Roche-Posay Effaclar Duo, the US version. It's really great for closed comedones because it's got both benzoyl peroxide and lipohydroxy acid, which are both comedolytic."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Salicylic acid

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.
