What the gurus are saying

Sulfur plus azelaic acid in one cleanser is the pairing gurus keep coming back to, and they found it calms redness without leaving dry, sensitive or acne-prone skin feeling stripped. The catch is the smell, which is real, though it's easier to live with than some other sulfur washes. Use it as an everyday cleanser, or leave it on briefly as a quick mask.

“Since I started using these, my skin has been so much less red than is average for me.”

Rosacea1 expert

“The reason it works so well for rosacea-type skin is that it has sulfur, which is kind of one of those catch-all ingredients that can help a wide variety of skin conditions: acne, rosacea, perioral dermatitis, seborrheic dermatitis.”

"I'm using my Prequel Redness Reform Cleanser, you can use this as a mask but I'm just using it as a cleanser. Prequel came through so much for me, I feel like I was just looking for the perfect cleanser and they ended up having it."

HONEST Ranking of Prequel Skincare (Too Honest?)

"The Redness Reform Sulfur Cleanser is incredible for my skin type, dry, acne prone, and sensitive. The 2.5% colloidal sulfur is such a good alternative to some of the more harsh and intense acne fighting ingredients. The con is it does smell bad, but to me it doesn't smell as bad as the L-ascorbic acid serum. I love that you can use this as a regular cleanser or leave it on as a [...] quick mask, with colloidal sulfur, azelaic acid, cica, alpha bisabolol, panthenol, and aloe vera."

Best VALUE Skincare (& worst too!)

"I love this brand so much. I talked about how wonderful it is to use, I love that it has both azelaic acid and sulfur, and this plus an oil based cleanser could just be everything I would ever need in terms of cleansing. What's extra fun about it is you can use it as a mask too, let it sit on your skin for a bit and then rinse off, and you get even more benefits from the actives because it's gentler since you ultimately wash it off."

"I genuinely think this is better than the Kate Somerville sulfur cleanser, even with less of that sulfur ingredient, because I swear it smells better and doesn't have as much of a smell. [...] It feels like a gentle and yet thorough cleanser and has a lot of calming ingredients in it. It's absolutely lovely, and it's also a more inexpensive product to start with. [...] My skin does not feel too dry after using it."

"And I have absolutely noticed a difference in my skin when it's feeling dry and reactive while using this. This came at the perfect time this winter because I had just increased my tretinoin prescription and it was so frigid and dry here. When my skin felt extra reactive, and the thought of a gel or foaming cleanser made it burn, I would reach for the Prequel Redness Reform Sulfur Cleanser and I absolutely felt a difference."

It also has azelaic acid. Do not sleep on azelaic acid. It's such a good ingredient for the skin, especially for redness-prone skin, and that's why it's in here."

"It's got a lot of soothing ingredients in it [...] and I've really enjoyed the cleansers I've tried from Prequel so far."

"You could use this as a morning cleanser or an evening cleanser. I've actually been loving using it in the morning because it sets my skin up to look its best throughout the day. [...] I'll take a pretty generous amount, work it into a rich lather, and then apply it to my face in the areas that I tend to get red, which is my cheeks, my nose, my chin, sometimes my forehead. And because this contains sulfur, I do keep it away from the eyes."

What the evidence says.

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

Azelaic acid

Azelaic acid has clinical evidence for both acne and rosacea, and it is one of the gentler options for calming redness while also working on marks left behind.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
