Deeper absorption caused by spicules can increase the risk of allergic reactions from layered products.Limited evidenceWhat we still need: When the skin barrier is broken by spicules, common cosmetic ingredients like fragrances and preservatives, which are otherwise safe on the surface, can be driven deeper, triggering allergic contact dermatitis.1 source

Silica spicules, as foreign material in the dermis, can cause delayed granulomas.Limited evidenceWhat we still need: The immune system can form granulomas around silica that remains in the dermis, and these reactions can be delayed by years or even decades, as shown in published cases.1 source

Product companies (VT, Medicube) do not disclose the actual length of spicules in their marketing.Limited evidenceWhat we still need: Despite the importance of spicule length for penetration and safety, neither VT nor Medicube's marketing materials provide this information; product numbers refer to concentration, not length.1 source

Spicules in microneedling creams are significantly longer than stated in marketing.Limited evidenceImportant caveatWhy it matters: This is a decision-relevant limitation.1 source
The spicules in products like VT Reedle Shot were measured to be 184-232 microns long, which is 10 to 15 times longer than the 15 microns often cited in marketing materials.

Spicule length, not width, determines penetration depth into the skin.Limited evidenceWhat we still need: The 15-micron figure found in marketing refers to the width of the spicule, but it is the length that determines how deeply the spicule can penetrate the skin, which is not disclosed.1 source

Spicules in these creams are long enough to penetrate into the dermis layer of the skin.Limited evidenceWhat we still need: With measured lengths of 184-232 microns, spicules are substantially longer than the human epidermis (30-65 microns thick), indicating they can reach the deeper dermis.1 source

Unlike traditional microneedling, spicules from these creams remain embedded in the skin.Limited evidenceWhat we still need: Research shows spicules stay embedded in the skin for extended periods (over 72 hours), which is a fundamental difference from traditional microneedling where needles are removed.1 source

Spicule creams, by physically penetrating skin, may require FDA oversight as medical devices.Limited evidenceWhat we still need: Under federal law, products that physically penetrate skin and claim to change skin structure are closer to medical devices, which typically require FDA approval or clearance, a question not currently being addressed.1 source
