Science
Mechanism of Action
Hydrolyzed Sponge functions as a biological microneedle system, comprising minute siliceous spicules. Upon topical application, these micro-particles physically penetrate the stratum corneum, forming numerous invisible channels that dramatically facilitate the absorption of key active ingredients, such as vitamin C, niacinamide, hyaluronic acid, and peptides, into deeper dermal layers. This action also provides gentle exfoliation by dislodging dead skin cells, thereby reducing skin barrier resistance and increasing the effective surface area for absorption. The mild, controlled stimulation triggers the skin's intrinsic self-repair mechanisms, significantly accelerating the metabolic rate and cellular activity. This process optimizes the efficacy of co-applied ingredients, promotes collagen proliferation, stimulates microcirculation, and can shorten the skin's natural renewal cycle from approximately 28 days to an estimated 7 days, leading to comprehensive skin improvements.

Key findings
- 01 Effective exfoliation has been observed in products utilizing Hydrolyzed Sponge at concentrations ranging from 45% to 75%.
- 02 Topical application of sponge spicules (from *Haliclona sp.*) significantly enhanced the transdermal penetration of 10 kDa molecules (fluorescein isothiocyanate-dextrans). In vitro studies on porcine skin showed a 33.09 ± 7.16-fold increase, while in vivo studies on BALB/c mice skin demonstrated a 72.14 ± 48.75-fold increase in penetration compared to control groups.
- 03 An 8-week split-face clinical study (n=20) comparing an epidermal growth factor (EGF) cream with and without spicules revealed a superior improvement in clinical wrinkle scores on the side treated with spicules in conjunction with the growth factor.

Stability
Hydrolyzed Sponge maintains optimal performance within a pH range of 4.5 to 7.0. Adhering to this range is critical for preserving its efficacy and compatibility with the skin's natural physiological balance. For water-based formulations, robust preservation strategies are essential to ensure product stability and prevent microbial contamination.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not provided direct safety assessments for 'Hydrolyzed Sponge' in its common form as siliceous spicules; separate evaluations for 'Hydrolyzed Spongin' exist. Regulatory statuses from the EU and FDA regarding its microneedle action are not explicitly detailed. Users may experience transient side effects such as redness, itching, and peeling, which typically resolve within 3-5 days and are considered normal post-application phenomena. Patch testing is strongly advised prior to full application to mitigate individual adverse reactions.
