What Is Humidophila Sp. Kas 1307?
Humidophila Sp. Kas 1307 is a strain of freshwater microalgae identified in scientific records under the code KT886105. Like other members of the Humidophila genus, it builds a tiny shell made mostly of natural silica. That shell gives the material a gentle gritty feel, which is why the beauty industry first took notice. Researchers looking for eco-friendly options to replace plastic microbeads found that finely milled Humidophila particles could polish the skin without harming waterways.
To create the cosmetic ingredient, the algae are grown in closed tanks filled with clean water and nutrients. Once the culture reaches the right density, it is filtered, the biomass is washed, then dried. The dry material is milled to different particle sizes depending on whether it will be used for a face scrub, a body polish or a light texturizer. A final heat step removes any residual moisture and helps ensure the powder stays stable on the shelf.
You will most often see Humidophila Sp. Kas 1307 listed on the labels of exfoliating cleansers, rinse-off masks, brightening pastes and occasionally in primers where a soft-focus feel is desired. Brands that position themselves as natural or ocean-friendly like it because the particles break down over time and do not linger in the environment.
Humidophila Sp. Kas 1307’s Cosmetic Benefits/Uses
This microalgae delivers two main benefits in skin care formulas:
- Abrasive: The silica shell creates smooth rounded particles that lift away dead surface cells and impurities when massaged on the skin. The result is a fresher look, improved softness and better absorption of follow-up products.
- Skin conditioning: Beyond its polishing role the finely ground powder leaves a light breathable film that can make the complexion feel smoother to the touch. Some users also report a mild mattifying effect because the particles help absorb excess surface oil.
Who Can Use Humidophila Sp. Kas 1307
The gentle rounded particles make this ingredient suitable for most skin types including normal, combination, oily and dull complexions that benefit from regular exfoliation. Dry or mature skin can also enjoy it if the formula contains enough emollients to offset potential moisture loss. Those with very sensitive, reactive or inflamed skin conditions such as active eczema or rosacea should use caution because any physical scrub can aggravate tenderness.
Because Humidophila Sp. Kas 1307 is sourced from microalgae and processed without animal derivatives it is appropriate for both vegans and vegetarians. Its plant origin also supports brands focused on cruelty free and eco friendly claims.
No data suggest the powder poses a risk to women who are pregnant or breastfeeding since the particles stay on the surface and are rinsed away. This is not medical advice and anyone who is expecting or nursing should still run new skincare products by a qualified doctor to be safe.
The ingredient itself does not trigger photosensitivity. However freshly polished skin can be a bit more exposed so daily sunscreen is wise. Aside from that there are no special lifestyle restrictions or ingredient conflicts to note.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Humidophila Sp. Kas 1307 can vary from person to person. The points below outline potential issues and do not represent the typical experience. When used correctly in a well formulated product most people tolerate the ingredient without trouble.
- Temporary redness or stinging from overzealous scrubbing
- Dry or tight feeling if the formula lacks sufficient moisturizers
- Microscopic surface scratches in very delicate skin
- Eye irritation if particles accidentally enter the eyes
- Rare allergic response to residual organic compounds from the algae
If any of these reactions occur stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Humidophila Sp. Kas 1307 scores a 1 out of 5 on the comedogenic scale. The particles are made of porous silica that sits on the surface and is rinsed away, so they are very unlikely to block pores. Because it is most often used in wash-off scrubs rather than leave-on creams, contact time with the skin is short which further lowers clogging potential. In short, the ingredient is generally suitable for people who are prone to acne or breakouts. Those who experience congestion primarily from physical friction rather than ingredient buildup may still prefer a chemical exfoliant, but that is a technique preference rather than an issue with the algae itself.
Summary
Humidophila Sp. Kas 1307 acts as a gentle abrasive and a light skin-conditioning agent. Its natural silica shell is milled into rounded micro-granules that physically lift away dull surface cells while leaving a fine film that smooths and lightly mattifies. The eco angle and microbead ban have made it a minor star in natural cleansers and body polishes, though it has not yet reached mainstream name recognition. Overall safety is high thanks to its inert mineral nature and quick rinse-off use, with side effects mainly tied to over-scrubbing rather than the material itself. As with any new skincare product it is wise to perform a small patch test first to be sure your skin agrees with the formula.
