Hydrolyzed Sponge is widely used in skincare as a biological exfoliating agent, especially in resurfacing, brightening, and acne-care products.
How Hydrolyzed Sponge Exfoliates
Hydrolyzed sponge is derived from freshwater sponge and contains microscopic siliceous spicules. These spicules are the key to its exfoliating action:
1. Micro-physical exfoliation
- The needle-like spicules gently penetrate the stratum corneum
- They mechanically loosen and lift dead skin cells without harsh abrasives
2. Stimulation of skin renewal
- Micro-stimulation accelerates epidermal turnover
- Promotes faster shedding of old keratinocytes and regeneration of new cells
3. Enhanced transdermal delivery
- Creates temporary micro-channels in the skin
- Improves penetration of active ingredients (e.g., peptides, niacinamide, acids)
Exfoliation Benefits
✔ Removes dead skin cells and keratin buildup
✔ Improves skin texture and smoothness
✔ Brightens dull skin tone
✔ Helps unclog pores and reduce comedones
✔ Supports fading of acne marks and hyperpigmentation
✔ Enhances efficacy of subsequent skincare products
