What Is Dactyliosolen Fragilissimus Extract?
Dactyliosolen Fragilissimus Extract is a marine derived ingredient obtained from the microalga Dactyliosolen fragilissimus, a member of the Rhizosoleniaceae family. Like many oceanic algae it is naturally packed with protective pigments, antioxidant vitamins, polysaccharides and trace minerals that help the organism survive in sunlit, salt-rich waters. Interest in algae based skincare grew in the late 1990s as formulators searched for renewable sources of antioxidants and hydration boosters, and this particular extract started appearing in niche spa lines before making its way into mainstream products during the past decade.
To create the cosmetic grade extract the algae are cultivated or responsibly harvested, then cleaned to remove salt and debris. The biomass is suspended in water and gently broken down using mechanical or enzymatic methods. The soluble fraction is filtered and concentrated, yielding either a clear aqueous solution or a spray-dried powder that can be blended into water phase formulations.
You will most often find Dactyliosolen Fragilissimus Extract in lightweight serums, anti-aging creams, daily moisturizers, after-sun gels, sheet masks, eye treatments and facial mists where its antioxidant profile supports skin vitality and defends against environmental stressors.

Comedogenic Rating
Rating: 0 / 5
Dactyliosolen Fragilissimus Extract is water based, lightweight and lacks pore clogging lipids so it does not build up in follicles or interfere with sebum flow. In standard concentrations it simply delivers antioxidants then rinses or absorbs away without leaving an occlusive film.
Suitable for acne-prone and breakout-prone skin.
Any risk of clogged pores would come from other, heavier ingredients in the overall formula not from this extract itself.
