Sponge Gel is a characteristic gel-building substance that absorbs a large amount of water like a sponge and releases it onto the skin for an immediate refreshing feel. The recommended usage rate for Sponge Gel is 0.5-5% (1.0% recommended for conventional formulations). This rate is used for its gel-forming function in a formula and is not related to Microneedle-like action or the long-lasting 72-hour effect you mentioned regarding the MFeel Serum brand.

Generally, the ingredient referred to as "Microneedle Sponge" or Bio-Microneedles typically refers to spicules derived from sea sponges, which are very small needle-like structures that can penetrate the skin to aid in exfoliation or deliver active ingredients. This type of ingredient may have a different mechanism of action and could potentially be related to a longer-lasting effect.

Based on the currently available information, the company does not appear to carry the specific Microneedle Sponge ingredient (sea sponge spicules) that provides a Microneedle-like action and a 72-hour long-lasting effect as you inquired about. The Sponge Gel product found is solely a gelling agent with water-absorbing properties.

Therefore, the 0.5-4% usage rate you saw might be a recommended rate for a different type of Microneedle Sponge ingredient, not the Sponge Gel sold by the company. Whether it can be applied daily depends on the specific type of Microneedle Sponge ingredient, the concentration used, and individual skin condition.
