Pseudoalteromonas Ferment Extract

Pseudoalteromonas Ferment Extract is derived from marine bacteria found in Antarctic ocean. It has humectant and skin soothing properties.

You’ll most often find this ingredient listed under the trade names Antarcticine or Arctalis.

According to a manufacturer, these ingredients encourage skin regeneration and smoothness by stimulating collagen and elastin production. A manufacturer study found creams containing 1–5% Antarcticine increased skin hydration and reduced wrinkle depth around the eyes.

A manufacturer also claims this extract can help regulate oily skin by reducing sebum production, shine, and minimizing pore size.

Some people have reported that ferments may trigger Malassezia folliculitis. For this reason, we list it as not fungal-acne safe, though individual reactions can vary.
