The SQT treatment is totally different from the peeling of algae. Algae powder or Spirulina powder is an unpurified powder, which contains a lot of plankton, dead branches or fallen leaves, and other impurities. It is a gray, gray-green, or brown powder with a fishy smell. There are a lot of broken needles, mostly used for Exfoliating.  The ingredients cannot stimulate the basal layer and cannot be compounded into other products as a single ingredient. With seriously exceeded microbes and heavy metals, algae peel patients are easily prone to skin allergies, inflammation, infections, and other damages.  SQT Bio Microneedling needles are a far more superior treatment with 99% pure needles working on the INSIDE layer of skin to activate the basal skin cell.  The SQT principle is mostly through needles.  Each gram of sponge spicules contains 3-5 million fine needles that penetrate the skin by pressing to open skin channels, absorb ingredients, and remove excess oil / promote skin microcirculation.
