Five quick questions to see whether Sulfur Soap fits your skin, and how to start.

The science

Why
sulfur works.

Sulfur works with your skin, not against it — targeting the oil and buildup behind congestion, without the harshness of stronger ingredients.

01

Balances oil

Absorbs excess oil without stripping — no rebound shine, no tight feeling after rinsing.

02

Clears pores

Gently exfoliates to lift dead skin cells and help keep pores clear. No scrubbing.

03

Calms

Soothes the look of redness so skin looks calmer and more even.

04

Gentle daily

Olive oil, shea butter and castor oil buffer the sulfur to support your skin barrier.

From the treatment room

“I formulated the Sulfur Soap for clients who were stuck in a cycle of harsh treatments that cleared their skin temporarily — and then made everything worse. Six ingredients. Ten percent sulfur. The same bar I recommend in my own practice.”

Karen, founder of skinbyKDUMedical Aesthetician · EASTND Wellness Clinic, Moncton

Good to know

Questions,
answered.

When will I notice a difference?
Many people notice less oil within the first couple of weeks. Use it daily and give it a full skin cycle — about 30 days. Consistency matters more than anything, and results vary from person to person.
Will it dry out my skin?
Olive oil, shea butter and castor oil buffer the sulfur, so it balances oil without stripping. If your skin feels dry, use it 2–3 times a week and follow with moisturizer.
How do I use it?
Wet skin with warm water, lather for 60 seconds, rinse and pat dry. Follow with your B or C Sérum on damp skin, then moisturizer. Sunscreen every morning.
Can I use it on my body?
Yes — face, back, chest or anywhere you break out. For body areas, dry brush first, cleanse, then moisturize right away.
