While double cleansing is trending now, Dr. Laszlo was the first to promote a two-step cleanse via oil and soap bar over 50 years ago. When you use our cleansing bars with our cleansing oils, you get the perfect double cleanse to remove excess skin surface oil, makeup, and other oily impurities through the cleansing oil. The cleansing bar itself helps to remove any remaining residue, deeply cleansing without drying.

Sea Mud Deep Cleansing Bar FAQs

Can I use Sea Mud Deep Cleansing Bar daily?

Yes, it’s gentle enough for everyday use including on sensitive skin.

How do I use it with the double-cleanse method?

Use Sea Mud Deep Cleansing Bar immediately after your Cleansing Oil. Massage the bar over damp skin to lift impurities, then rinse thoroughly. This combination enhances purification while leaving skin feeling soft and balanced.

Can I mix and match Erno Laszlo Cleansing Oils for my Double Cleanse?

Yes! You can use Detox Cleansing Oil or Phelityl® Cleansing Oil to address your skin’s unique needs while still following Dr. Laszlo’s double-cleanse ritual.

Can I use it alone?

Yes, it cleanses effectively on its own, though combining it with a cleansing oil enhances makeup removal and overall purification.

Will it leave a residue on my skin?

The bar contains glycerin to help maintain hydration without drying the skin. Some users may notice a slight slickness initially, which rinses away quickly when followed by lukewarm water.

How long does the bar last?

With daily use, the Sea Mud Deep Cleansing Bar (100g) typically lasts 6-8 weeks, depending on how much you use per cleanse and how it’s stored. The 50g Bar will last 3-4 weeks.

Does it stain?

No. The bar is formulated to cleanse the skin without staining sinks, counters, or towels when used and rinsed properly.

How should I store it?

Keep it dry between uses in a ventilated soap dish to preserve its texture and longevity.
