From the OCEAN to your SKIN

Instant Tensor Serum:


Instant Tensor Serum has an immediate tightening effect, filling wrinkles and fine lines, plumping the skin, refining skin texture and reducing skin sagging. It also deeply moisturizes and softens the skin.

Instant Tensor Serum Ingredients


Pure Isotonic Seawater

Pure Isotonic Seawater revitalizes and remineralizes the skin by a synergic diffusion of minerals and trace elements. Collected from a protected area, outside pollution, the seawater is filtered of all impurities and sterilized by microfiltration. Seawater at a perfect degree of salinity creates an isotonic environment for cells. Thus the concentration of water is similar in solute to that of the membrane of our cells. Cells will recognize the same concentration and take what they need in minerals and trace elements for an optimum effect. Through biomimicry, seawater increases the product’s effectiveness by promoting the diffusion of active ingredients through the skin barrier.

  • Revitalizes
  • Soothes
  • Protects the skin


PEPTIDES Wheat protein complex

The wheat protein complex contains hundreds of amino acids that form hydrolyzed proteins called peptides. Peptides are the latest technological advancement used for their revolutionary antiaging effects. Peptides bind to the skin to form a smooth and elastic film that tightens the epidermis for an immediate firming effect. Peptides also strengthen the resistance of the skin which helps prevent the effect of loose and sagging skin.

  • Immediate tightening effect
  • Reduces wrinkles and fine lines
  • Refines skin’s texture


BROWN ALGAE Sphacelaria scoparia

This species of brown algae activates collagen synthesis for a remodeling and firming effect.

  • Reshapes the facial contours
  • Reduces wrinkles and fine lines


HYALURONIC ACID Low molecular weight (LMW)

Hyaluronic Acid is a micro-molecule that penetrates into the epidermis layer of the skin providing deep moisture and a plumping effect. Hyaluronic Acid occurs naturally in the body and is one of the most important elements that form the structure of the skin. The function of Hyaluronic Acid is to attract and retain water in the skin by forming an elastic gel; this gel contains up to 20 times its weight in water. However, the quality and quantity of Hyaluronic Acid our body produces is diminished due to the natural process of aging accompanied by external factors like UV radiation and pollution; eventually, the skin starts to lose its elasticity, and wrinkles begin to appear. The addition of Hyaluronic Acid to the Instant Tensor Serum hydrates and plumps the skin resulting in are rejuvenated and revitalized appearance.

  • Moistures deeply
  • Plumps the skin
  • Fills wrinkles and fine lines


FUCOCERT® Plant origin Polysaccharide from organic certified agriculture

Organic Fucocert is composed of polysaccharides from plant origins that provide excellent moisturizing and soothing effects. Polysaccharides are sugars that exist naturally in the skin and play an important role in cellular communication; they also help fight dehydration by forming an aqueous film to help reduce water loss. Fucocert stimulates cellular renewal and contributes to visibly younger skin.

  • Moistures deeply
  • Soothe immediately
  • Anti-aging action



Red algae gel contains Chondrus crispus extracts, also known as Sea Lichen. Sea Lichen is a red algae that lives on coastal rocks and is rich in sulfated polysaccharides, essential amino acids, vitamin C, magnesium, iodine, iron, copper, and zinc. Red algae gel moisturizes, soothes, heals, softens, remineralizes, and brings radiance and brightness to the skin.

  • Skin looks visibly younger
  • Brighter complexion


BARLEY ORGANIC FLORAL WATER from organic certified agriculture

Barley organic floral water is a concentrate of nutrients rich in vitamin B, carotenoids, mineral salts, essential amino acids, and trace elements. This concentrate contains nourishing and revitalizing properties that regenerate the skin for a visibly brighter and more youthful appearance.

  • Brighter complexion

Instant Tensor Serum Reviews

"When this serum was introduced at our convention, we were instructed to apply it to only one side of the face. Within 5 minutes of applying, the person I was speaking with shouted at the difference in my face. As I was heading to the ladies room to see the difference myself, so many other people stopped me and told me which side of my face I applied the Tensor Serum! They were all correct! Loads of laughs and very empowering!”

Olympia Kallman, USA

“I have mature skin and I noticed that fine lines around my eyes, and my skin, in general, looks and feels firmer and hydrated.”

Cherie Mehrtens, NZ

“C’est magnifique - Outstanding results with luxurious natural ingredients, a beautiful gift from the sea. My clients are saying ‘I need some more of that divine Serum."

Carol Ford, NZ

“I had been using a competitor's skincare products for a while and I have now switched over to the Instant Tensor Serum & CC Cream for my dry skin. I just love it, my face feels so smooth! I need the moisture in my skin because winters are cold here in North Dakota and both of these products provide exactly what I need.”
