How a high-density reedle shot serum delivers concentrated actives beyond what surface application can reach — and what the density number means

What the 1300 in Reedle Shot 1300 means and what it implies about delivery

The 1300 designation refers to the micro-tip density on the application device — 1300 micro-polymer tips per square centimetre on the roller or stamp applicator. Higher tip density means more simultaneous micro-perforations in the stratum corneum during application, which translates to more uniform temporary permeability increase across the skin surface. This is not microneedling: the tips are short (sub-0.3mm) polymer structures that temporarily disrupt the very outermost stratum corneum barrier rather than penetrating to the viable epidermis. The high density ensures comprehensive, even coverage with minimal pressure required per tip.

What happens to active ingredient penetration through 1300 simultaneous micro-entry points

The simultaneous creation of 1300 temporary micro-entry points per square centimetre creates a temporary window in which water-soluble active molecules can penetrate the stratum corneum more efficiently than through intact skin. For concentrated serums applied immediately after or through the micro-tip device, this translates to active ingredients reaching the deeper stratum corneum layers faster and in higher quantities than standard topical application. The penetration improvement is most significant for molecules that are normally limited by the stratum corneum's resistance.

How the concentrated formula in a reedle shot serum differs from a standard serum

A reedle shot serum is typically formulated at higher active concentrations than a standard daily serum, on the basis that the micro-tip delivery mechanism will produce greater penetration from each application. The concentrated formula combined with the penetration-enhancing delivery mechanism is designed to deliver the active payload at a depth and concentration that would require clinical treatment to achieve through surface application alone.

The appropriate use frequency for a high-density reedle shot product

A high-density reedle shot product used daily would over-stress the stratum corneum with repeated micro-disruption before the previous session has fully recovered. The appropriate use frequency for a 1300-density product is two to three times per week, allowing the stratum corneum to fully recover between sessions. On non-reedle days, a regular leave-on serum maintains the active ingredient routine without the added penetration-enhancement mechanism that the disrupted barrier needs to recover from.
