What is Blue Beauty?

Blue Beauty means effective ocean-based skincare + sustainable practices + responsible sourcing + preserving marine ecosystems.

Why is blue beauty important to Cold Current Kelp?  Most seaweed skincare products sold in the U.S. use imported, untraceable or wild harvested seaweed.  Some use yellow and blue dyes to create an artificial seaweed-green color.

Our kelp is grown not just sustainably, but regeneratively – it actually promotes marine health – in local Maine waters.  The kelp used in every Cold Current Kelp product is traceable down to the latitude and longitude coordinates off the coast of Maine.  We perform heavy metal and other safety testing. Our products are dye-free and are an earthy green in color reflecting kelp’s naturally-occurring pigments that play a key role in skincare.

Our team takes a science-based, environmentally friendly approach to skincare product development, including:

  • Researching drying and handling methods to preserve kelp’s bioactive compounds
  • Adopting an extraction method to obtain desirable compounds from our kelp without residual chemicals
  • Using patented ultraviolet bottles that block the full spectrum of light, allowing only UV-A / Infrared to penetrate the glass.  This preserves nutrients and extends shelf life.
  • Using beautiful, recyclable packaging and shipping materials that incorporate simple cardboard and kelp; no plastic bubble wrap.

Kelp in Skin Care

The seaweed in our KelpGlow Facial Oil is sugar kelp, Saccharina latissima. Sugar kelp is a macroalgae that has evolved to grow and thrive in harsh and variable conditions with exposure to extreme changes in sunlight and temperature. Kelp’s physiology changes due to its adaptive strategies – it produces secondary metabolites that act as antioxidants to help protect its tissue. 

Studies* have shown that when these compounds are applied to human skin, they have the same antioxidant benefits. These bioactive compounds include polysaccharides, polyphenols, amino acids, UV-absorbing pigments, vitamins, and minerals – and are what make sugar kelp an effective, natural and sustainable skincare ingredient. Scientific studies* show evidence that the bioactive compounds in kelp have many skin-protecting benefits, including:

Antioxidant

Polysaccharides like fucoidan, laminarin, and alginate, vitamins C and E, and phlorotannins possess potent anti-oxidative activity to help protect skin from damaging free radicals.

Age-Defying

Fucoidan is known to be an effective compound in the prevention of premature skin aging. Pigments (fucoxanthin, carotenoids), amino acids, and phlorotannins protect skin cells from UV-induced aging.

Soothing

Laminarin has calming and redness-reducing properties.

Hydrating

Polysaccharides and amino acids in brown algae have maximum water-holding capacity, and act as a humectant and moisturizer — hydrating and improving appearance of the skin and fine lines.

Brightening

Amino acids found in kelp help skin maintain firmness; polysaccharides like fucoidan and laminarin boost skin’s radiance and reduce redness, while vitamins and minerals support skin cell turnover.
