Science
Mechanism of Action
Spongilla spicules, tiny needle-like silica structures, gently polish the skin and create micro-channels. This enhances active ingredient penetration, stimulates microcirculation, accelerates cell turnover, and promotes collagen and elastin regeneration for smoother, firmer skin.

Key findings
- 01 99% Spongilla spicules with 0.5% BHA effectively treated acne-prone skin and improved texture over three sessions (J Dermatol Adv Clin Care).
- 02 Spongilla spicules improved skin firmness, cell regeneration, reduced wrinkles, and combated aging/acne (Chengdu CosmoBiotech).
- 03 Hydrolyzed sponge spicule promoted collagen regeneration, improved firmness/elasticity, and reduced fine lines/acne (NINGBO INNO PHARMCHEM CO.,LTD.).
- 04 Spongilla lacustris facilitated hydrogen peroxide penetration for acne vulgaris treatment on rat skin, safe for short-term use (J Med Assoc Thai).

Dusting Analysis
Sponge Extract delivers active Spongilla spicules, which provide a distinct physical action for exfoliation and skin renewal, making it an unlikely candidate for 'dusting' purposes.
The Formula
Formulation
Stability
Optimal performance is within pH 4.5-7.0. While the hydrolyzed sponge is water-soluble, its active spicules are partially insoluble. Ensure proper preservation in water-based products and avoid strong acids or alkalis during processing.

Safety
Safety Profile
Generally safe for cosmetic use, suitable for all skin types, including sensitive; patch testing is prudent. Limited data for pregnancy/breastfeeding, consult a healthcare professional. Long-term safety concerns regarding potential granulomatous reactions from silica exist.
