Performance Scores

SPF Level

Excellent

Homosalate provides targeted UVB protection with a peak absorption at 306 nm, complemented by the broad-spectrum UVB/UVA attenuation of Bemotrizinol.

Broad Spectrum

Fair

Photobiology research confirms Bemotrizinol (Tinosorb S) covers the critical UVA I and UVA II ranges (peaks at 310 nm and 340 nm), acting as the sole UVA defense in this formula.

Sweat Resistance

Fair

Ingredients like Phenyl Trimethicone, Dimethicone Crosspolymer, and amino acid-based gelling agents (Dibutyl Lauroyl Glutamide) create a highly water-repellent, solid film on the skin.

Photo Stability

Fair

Cosmetic science literature demonstrates that Bemotrizinol remains 98.4% intact after heavy UV exposure and acts as an active triplet-state stabilizer for other photolabile filters.

Visible Light

Poor

Absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or pigmentary non-nano minerals in the active and inactive ingredient list.

Irritation Risk

Low Risk

The ingredients are widely recognized in dermatological literature as non-irritating, non-sensitizing, and fundamentally barrier-supporting.

Pore Clogging

High Risk

Dermatological literature and established comedogenicity scales consistently rate algae and seaweed extracts (like Laminaria Digitata) as highly comedogenic (4-5/5) due to their potential to induce follicular hyperkeratosis.

White Cast

Low Risk

The complete absence of zinc oxide or titanium dioxide means the physical mechanism for white cast is inherently eliminated.


Ingredients Analysis

Active Filters

Homosalate ChemicalUVB

Laboratory studies indicate homosalate may act as an endocrine disruptor by interfering with hormone systems [1.1].

Bemotrizinol ChemicalBroad Spectrum UV

Identified in recent dermatological literature as a rare but emerging cause of allergic contact dermatitis.

May contain trace amounts of cyclic siloxanes (such as D4 and D5) from the manufacturing process, which are restricted in the EU due to environmental bioaccumulation concerns [2.7].

Functions as a synthetic polymer microbead that is often classified as a microplastic, raising concerns about environmental persistence and marine pollution.

Laminaria Digitata Extract Botanical ExtractSkin Conditioning

Algae and seaweed extracts including Laminaria digitata are frequently flagged as pore clogging and may exacerbate breakouts in acne prone skin [1.2].

Cetyl-PG Hydroxyethyl Palmitamide CeramideSkin Conditioning

Subject to EU Cosmetics Regulation Annex III limits on secondary amine impurities to prevent the formation of potential nitrosamines [2.2].
