 These Are the Main Differences Between Physical and Chemical Sunscreen |
MAAs
(Mycosporine-like Amino Acids)
Mycosporine-like Amino Acids (MAAs) are small-molecule natural compounds renowned for their exceptional ultraviolet radiation-absorption properties. These compounds are ubiquitous in the natural world, occurring in a variety of organisms, ranging from microorganisms to invertebrates and vertebrates. MAAs serve a dual purpose: they naturally shield against ultraviolet radiation while also possessing the ability to mitigate skin oxidation and alleviate skin inflammation, redness, and related dermatological conditions.
Common sunscreen products adversely affect marine ecosystems
Approximately every year14,000 tonsSunscreen is washed off and discharged into the ocean, where approx.10% is hydroxybenzophenone, far exceeding the minimum concentration of coral bleaching, hydroxybenzophenone puts 15% of the world's coral reefs and 40% of coastal waters at a lethal threat.

MAAs - the most efficient molecules for absorbing UV rays
MAAs are the most efficient molecules at absorbing ultraviolet radiation, spanning the full spectrum from 268nm to 362nm, which encompasses UVA (315nm to 400nm), UVB (280nm to 315nm), and even UVC (100nm to 280nm). They not only excel at shielding against UVA radiation but also offer effective protection against UVB radiation. Consequently, MAAs are integral components in beauty and skincare products, particularly prized for their natural attributes. This distinction extends beyond skin safety, as they also preserve marine ecosystems, rendering them suitable for aquatic activities.
MAAs secondary properties
MAAs are not only an effective and safe natural sunscreen ingredient,
It also has secondary properties such as antioxidant, anti-inflammatory, and wound healing properties;
Advanced, eco-friendly sunscreens with skin cancer prevention capabilities could be further explored.
MAAs market status
MAAs have not yet been produced and applied on a large scale.
MAAs currently on the market are mainly extracted from natural algae using polar solvents such as methanol and ethanol. They usually face the following problems:
1: Natural algae grows slowly.
2: The content of natural algae MAAs is low and the extraction process is complicated. Therefore, the price of MAAs currently on the market is very expensive.
Prismaa®-MAAs
1. Biologysafety:Spirit Spider MAAs passedmicrobial fermentationObtained, the raw materials used are all food-grade compounds, safe and non-toxic.
2. High production efficiency:The Saccharomyces cerevisiae strain exclusively modified by LINK SPIDER has superb production capacity.Yieldcan reachHundreds of times more than natural algae, can carry out large-scale production, simplify the production process, and save manpower and resources.
3. High purity:Through synthetic biology construction, the synthesis conditions of MAAs can be controlled to ensure high-purity MAAs products.
4. Product specificity:Natural MAAs are typically mixtures of multiple molecules, but LINK SPIDER can produce specific natural sun protection components with precision including shinorine, porphyra-334, palythine-serine, palythine-threonine.
