BIODANCE Refreshing Sea Kelp Real Deep Mask 34g

Calm oily, breakout-prone and easily irritated skin while restoring a healthier balance between oil and moisture with the BIODANCE Refreshing Sea Kelp Real Deep Mask 34g.

This cooling Korean hydrogel mask is powered by 10% Lactobacillus/Kelp Ferment Filtrate together with mineral-rich Deep Sea Water to soothe visible redness, reduce excess sebum and refine uneven-looking skin texture without leaving skin feeling stripped or dry. BIODANCE positions fermented sea kelp as an “ocean-derived cica,” reporting five times stronger soothing activity than 2% Centella Asiatica extract in its in-vitro comparison.

Unlike traditional oil-control masks that can leave the complexion tight, Refreshing Sea Kelp focuses on oil-moisture balance. BIODANCE reports a 21.9% reduction in sebum and approximately 44% improvement in oil-water balance in its product testing, making it particularly interesting for combination and oily skin that can still become dehydrated.

The concentrated essence is solidified into BIODANCE's signature hydrogel, which gradually becomes transparent during wear. Leave it on for 3–4 hours or overnight for an intensive calming, balancing and hydrating treatment.

What Does Refreshing Sea Kelp Real Deep Mask Do?

Oily skin isn't necessarily well-hydrated skin.

When skincare focuses too aggressively on removing oil, the complexion can become dehydrated, tight and uncomfortable while still producing excess sebum. Refreshing Sea Kelp takes a different approach by combining soothing fermented kelp with marine minerals to help bring oil and moisture back into better balance.

BIODANCE reports that the mask reduced measured sebum by 21.9%, improved oil-water balance by around 44%, and improved skin texture by 10.31% in its testing.

That gives this mask a very clear purpose:

Excess Oil + Redness + Breakouts + Uneven Texture + Dehydration → Sea Kelp

Who Is It For?

Ideal for:

• Oily skin
• Combination skin
• Breakout-prone skin
• Skin with excess sebum
• Congested-looking skin
• Visible pores
• Uneven or rough-looking texture
• Red or easily irritated-looking skin
• Oily skin that also feels dehydrated
• Skin that becomes shiny during the day
• Anyone wanting a soothing Korean overnight mask without a heavy finish

What's the Best Korean Face Mask for Oily, Breakout-Prone Skin?

If your skin is oily but also easily becomes red, irritated or dehydrated, simply using stronger oil-removing products isn't always the best approach.

Refreshing Sea Kelp is specifically formulated for oily and breakout-prone skin, combining fermented kelp with marine minerals to help reduce excess sebum while maintaining hydration.

Its 21.9% measured sebum reduction alongside improved oil-water balance makes it especially relevant when the problem isn't simply oiliness, but:

Oiliness + Dehydration + Redness + Breakouts

Can Oily Skin Be Dehydrated at the Same Time?

Yes. Oil and water are different components of the skin.

Skin can produce plenty of sebum while still lacking adequate moisture, which is why some oily complexions can simultaneously feel tight, uncomfortable or dehydrated.

Rather than focusing only on removing oil, BIODANCE designed the Sea Kelp mask around restoring oil-moisture balance while calming the skin. The brand reports approximately 44% improvement in oil-water balance in three days under its test conditions.

This makes it particularly useful for combination skin that feels oily in the T-zone but dehydrated elsewhere.

BIODANCE Sea Kelp or Hydro Cera-nol – Which Should I Choose?

Choose Refreshing Sea Kelp when your priorities are:

Oiliness → Excess Sebum → Breakouts → Redness → Uneven Texture → Oil-Water Balance

Choose Hydro Cera-nol when your priorities are:

Dryness → Dehydration → Sensitivity → Weakened Skin Barrier → Intensive Moisture

Both are soothing hydrogel masks, but their primary skin concerns are different. Sea Kelp is BIODANCE's targeted blemish and sebum-control line, while Hydro Cera-nol is primarily focused on deep hydration and barrier support.
