70 MARINE INGREDIENTS The marine ingredient at 3% decreased
wrinkle length by 40.6%±13.2% (Figure 5), data supported by the outstanding increase in elasticity of 39.9% in crow’s feet area (Figure 6A) and 29.1% in eye bags after 28 days (Figure 6B).
The marine ingredient increased moisture
from day 0 to day 28, 10.7% in crow’s feet area (Figure 7A) and 16.5% in eye bags area (Figure 7B). The above results highlight that the marine ingredient is a potent well-ageing. Additionally, the marine ingredient was
shown to reduce dark circles by 25.6%±11.7%. Moreover, it helped to reduce the angle formed by eye bags by 10.6%±4.6% (Figure 8), and lifted eyelids in a 10.9%±5.4%.
Tips for formulators The marine ingredient is composed of a blend of polyphenols, proteins and saccharides extracted from nannoplankton as an upcycled ingredient from a green and environmentally friendly downstream process. This 360º eye contour ingredient is water-soluble, 100% natural origin content (ISO 16128), and Vegan and COSMOS-approved. The marine ingredient is easy to formulate
together with other natural ingredients to produce an eye contour end product that covers marketing claims such as: well-ageing to reduce crow’s feet, eye bag wrinkles, eye bag area and improved antioxidant action. It also offers benefits such as eyelid
tensor effect; firming and lifting thanks to the moisturizing effect and elasticity increase; and whitening, reducing dark circles. An example of eye contour formulation is shown in Table 2.
Conclusions OpenSee Phycoskin® is composed of four key molecules: the polyphenols 4-hydroxybenzaldehyde and marine gallic acid, and the proteins thioredoxin and FSA-1 domain protein, which together have been shown to cover multiple claims related to eye contour: ■ Exhibited high antioxidant capacity ■ Increased collagen type I and elastin at only 0.3% dosage ■ Increased elasticity and moisture ■ Reduced wrinkle length by 40.6%±13.2% ■ Reduced dark circles by 25.6%±11.7% ■ Reduced eye bag`s area by 10.6%±6% ■ Exhibited eyelid tensor effect by 10.9%±5.9%
