Kelp! Seaweed Serum Sheet Mask (Pack of 4)

Flood your skin with hydration and radiance. Our KELP Seaweed Sheet Mask is infused with an intensive, collagen-supporting serum that restores moisture, plumps fine lines, and soothes even the most sensitive complexions. 

  • Deeply hydrating: Serum-rich formula quenches skin and locks in long-lasting moisture.
  • Collagen supporting: Marine actives help boost skin’s natural collagen for firmer, plumper texture.
  • Barrier-strengthening: Protects and balances the skin barrier for improved resilience.
  • Calming & soothing: Reduces redness and irritation while reviving tired, stressed skin.
  • Radiance-restoring: Leaves skin luminous, fresh, and glow-ready.

Apply to clean, dry skin. Leave on for 15–20 minutes. Remove and gently pat in any remaining serum—no need to rinse.

Pro tip: Store in the fridge for extra cooling benefits.

Obsessed

"This is the only mask I have found which actually calms my red face. It leaves a great serum on the skin afterwards too giving me a really dewy finish. I also love that I can just throw it into my garden afterwards."

— Andrea (5/5)

Life saving

"When i used this mask once a week everyone was commenting on how glowing my skin was, even after flights I glowed as I live abroad and usually my skin would be dehydrated. using it ON a flight is next level glow after. I used a product from another range with AHA which made me so sensitive and my skin was burning and this calmed me immediately also. It's a life saver."

— Laura (5/5)

Feels so luxurious!!

"This product is truly amazing. It feels so fresh on the skin and smells like the ocean! After removing the mask you are left with such a gorgeous glow. It’s so luxurious compared to other sheet masks on the market and I would recommend this product to everyone!"

— Liana (5/5)

Amazing products! ⭐️ ⭐️⭐️⭐️⭐️

"What a joy it is to use these products! It isn’t often that I buy a whole line of products, but I did with this one! The seaweed mask is the best I’ve ever used…I feel like I’m literally coming out of the sea! The Super Balm is magical! I use it all over my face, and it’s amazing to calm blotches, and great for moisturizing my lips. I could go on and on, but the natural fragrance of each product is mind-blowing! You’re not just cleaning and moisturizing, you’re enjoying a spa day! Run, don’t walk to get these products. Also, the travel package is a perfect introduction to the entire line!💚💚💚"

Fantastic Results

"I couldn't believe how good my skin looked after using. I love the way the mask is in 2 parts-making it so much easier to use than other sheet masks. The glow achieved was really pleasing and I got such a lot of compliments! An absolutely gorgeous product. Using it was like taking a spa mini break and gave my complexion such a boost! Will definitely include this in my routine on a regular basis."

My favourite masks! I’ve just

"My favourite masks! I’ve just recently had my skin flare up on my face and I cannot even begin to describe how amazing these masks have been. They’re super soothing and the only mask I would trust to never cause any irritation to my skin ❤️ They’ve really helped restore moisture and hydration and I’m finally looking glowy again. These are definitely a must have in your weekly routine"
