Hydrolyzed Sponge (Spicules) is a refined form of natural sponge micro‑crystals that provide a whisper-soft, tactile polish on the skin’s surface. This gentle micro-exfoliation smooths uneven texture and helps your next layers absorb more effectively for a lit-from-within finish. Ideal for most skin types looking to boost glow and softness; if you’re new to spicules or easily reactive, start slowly and listen to your skin.
