What the gurus are saying

This sulfur cleanser wins praise for tackling redness and rosacea while avoiding the harsh smell and stripped feeling typical of sulfur products. The formula stacks sulfur with soothing actives (azelaic acid, shea, panthenol, aloe) that reviewers found reduce inflammation without harshness. Some apply it as a mask, letting a thick layer sit for a few minutes before rinsing.

"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. I used to love a much more expensive sulfur cleanser from Kate Somerville, and this is everything that was and more, and it's less expensive. I absolutely adore this."
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. The only problem with the brand is that sometimes their products go out of stock and it seems to take a while to restock."

"This is Prequel's newest release, a 2.5% sulfur and azelaic acid cleanser, and it's just so much up my alley. 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."

"If you have redness-prone skin, rosacea-prone or an actual rosacea diagnosis, you have to check out the Prequel Redness Reform Sulfur Cleanser. [...] Since I started using these, my skin has been so much less red than is average for me. [...] 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. 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. There's also a soothing ingredient in there that's great for the skin. This is technically a cleanser, but I like to use it as a mask. [...] I take a good amount, apply it all over my face in a thick layer, [...] and let it sit for two to five minutes if I have enough patience, letting it work as a mask before I wash it off."
Yay
"It's got a lot of soothing ingredients in it [...] and I've really enjoyed the cleansers I've tried from Prequel so far."

"I have not tried the Prequel sulfur cleanser yet. Prequel has some wonderful options though as far as their skin care. The majority of things I've tried from them have been good if not stellar."
Yay
"This cleanser is formulated with protective acacia senegal gum colloid, which is essentially a molecular complex that helps improve the dispersion and efficacy of sulfur within the formula and helps reduce the odor of sulfur. People often associate sulfur with that strong unpleasant smell of rotten eggs, but this cleanser is actually very pleasant because of the mindful formulation. [...] While there's just the slightest hint of sulfur, it's not off-putting. And that matters because using your products consistently is how you get the best results. In addition to sulfur, this cleanser is also formulated with a full stack of soothing ingredients. There's azelaic acid in a hydrosoluble patented form to support clearer, more even tone. Shea to calm sensitized skin and support the skin barrier. Alphitol, a potent antioxidant that soothes and brightens. Panthenol for improved hydration and elasticity. And aloe vera to soothe immediately. There are also a few calming ingredients [...] like fitins osmanthis, a unique antioxidant with proven calming properties, neocensil, a targeted soothing complex for sensitive skin, and guazelene, known for soothing and responsible for the cleanser's natural green tint. Every ingredient here is doing something intentional. [...] This is an ultra plush foaming cleanser that creates a gentle cushiony lather. When I use this, I feel clean and refreshed but never stripped, tight or dry. 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."

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.
