  • The 73.4% dermal absorption and penetration benefits demonstrated with 200-320 micrometer spicules cannot be assumed for lower-grade or completely broken sponge powders, which lack intact needle geometry.
  • The micro-channel delivery advantages shown in leave-on gel or cream formulations cannot be translated to wash-off foaming cleansers, which are quickly rinsed off before penetration can occur.
  • Topical micro-needle application cannot be assumed to replace or replicate the depth of clinical microneedling procedures, which reach depths of up to 2.0 mm into the dermis.
