Product Information

What makes the microneedle patches unique is that they are made from a hydrogel (a gel-like substance in which water forms the liquid component), with the active ingredient encapsulated inside the hydrogel microneedle structure rather than in a separate reservoir. She said: “You can experience gastrointestinal side-effects; there is a delay between taking the medication and the drug getting to where it’s needed in the body; doses need to be higher because a lot of the formulation is broken down in the gut, and if the patient is taking antibiotics, this can also contribute to antimicrobial drug-resistance.'

If you’re looking for a one-stop shop for sorting out your pimples, then you won’t find pimple patches better than the CORSX AC collection acne patch. The main ingredient aside from the hydrocolloid base is centella asiatica extract, which is typically used topically to heal wounds, repair the skin barrier and treat skin conditions such as psoriasis. The formula is both gentle and effective on the skin, so each patch leaves no trace after application, and is effective at busting breakouts pimples at any stage. During testing, we also found that these patches helped to bring ingrown hairs to the surface. Invention relates to plastic microneedle strips that are used in TDD for increasing the DD rate through the skin. Microneedles were first mentioned in a 1998 paper by the research group headed by Mark Prausnitz at the Georgia Institute of Technology that demonstrated that microneedles could penetrate the uppermost layer ( stratum corneum) of the human skin and were therefore suitable for the transdermal delivery of therapeutic agents. [8] Subsequent research into microneedle drug delivery has explored the medical and cosmetic applications of this technology through its design. This early paper sought to explore the possibility of using microneedles in the future for vaccination. Since then researchers have studied microneedle delivery of insulin, vaccines, anti-inflammatories, and other pharmaceuticals. In dermatology, microneedles are used for scarring treatment with skin rollers.

It is possible that the fluorescence signals on microneedles are generated by other cytokines or chemokines whose concentration also increase after LPS injection. To investigate the specificity of the test, we incubated different concentrations of human IL-6, mouse IFN-γ, mouse TNF, mouse IL-12, mouse CXCL9, mouse CCL19 and mouse CCL20 with mouse IL-6 capture antibody, followed by mouse IL-6 detection antibody and HRP or plasmonic fluor (concentration and source of each protein were listed in Supplementary Table 2). For conventional plate-based ELISA, p-FLISA and microneedle-based p-FLISA, assay methods and reagents were identical to those mentioned above. This project could provide a revolutionary approach to vaccination in the future. As a long-term partner of Innoture, we look forward to supporting this exciting venture”.

Since their conceptualization in 1998, several advances have been made in terms of the variety of types of microneedles that can be fabricated. The 5 main types of microneedles are solid, hollow, coated, dissolvable/dissolving, and hydrogel-forming. [2] Solid [ edit ] Muller, D. A., Corrie, S. R., Coffey, J., Young, P. R. & Kendall, M. A. Surface modified microprojection arrays for the selective extraction of the dengue virus NS1 protein as a marker for disease. Anal. Chem. 84, 3262–3268 (2012). In a more recent adaptation of the microneedle design, dissolvable microneedles encapsulate the drug in a nontoxic polymer which dissolves once inside the skin. [1] This polymer would allow the drug to be delivered into the skin and could be broken down once inside the body. Pharmaceutical companies and researchers have begun to study and implement polymers such as Fibroin, a silk-based protein that can be molded into structures like microneedles and dissolved once in the body. [12] Hydrogel-forming [ edit ] Considering that the antibodies are immobilized on the microneedles, it is important to understand the stability of these proteins during the penetration of the microneedles into the dermal tissue, residence in the dermal tissue and subsequent withdrawal (Supplementary Fig. 12a). To test this, we coated microneedles with fluorescently labelled BSA (used as a model protein) before application onto mouse skin for different durations (15 s, 10 min, 20 min, 30 min and 60 min). Upon withdrawal, microneedles exhibited a loss of around 20% in fluorescence intensity, indicating that a small fraction of proteins had desorbed from their surface, possibly due to the shear forces between the microneedle surface and the epidermis (Supplementary Fig. 12b). The decrease in the fluorescence intensity (representing the amount of protein lost) did not depend on the residence time of the microneedles in the dermal tissue, indicating minimal loss from desorption or proteolytic degradation of these proteins in the dermal tissue, even for a residence time of 60 min.

That means that the active ingredients can get to work faster than if they were plonked right onto the skin’s surface. Don’t worry though, the needles aren’t painful as they’re made using water-soluble materials such as hyaluronic acid so that they dissolve into the skin over time, dispersing any skin-loving products they’re coated in.

As opposed to in vitro diagnostics that involve sample acquisition (such as blood or urine) at a specific time point along the disease progression and analysis at a later point in time, in vivo diagnostics involving capture of target analytes from a dynamically varying matrix (for example, dermal ISF in the present case) is inherently a non-equilibrium condition. This is particularly true for the cases in which the target analyte concentration varies within the sampling timescales, for example, IL-6 level in LPS-stimulated mice. In such cases, the concentration determined using microneedle patches represents a time-average concentration of the analyte in ISF over the sampling period. From a diagnostic translation standpoint, this time-averaged concentration can be standardized by setting rigorous guidelines for microneedle administration (for example, administration time, location) and ex vivo analysis (for example, standard curve conditions). Detection and quantification of endogenous matricellular protein in periosteum The patch also works in reverse, extracting small quantities of fluid from beneath the skin for medical analysis. This may be helpful, for instance, for monitoring the levels of lactate (a component of lactic acid) and other chemicals in patients with an infection. Clear benefitsMicroneedling patches, on the other hand, provide a more efficient delivery system for HA, by "creating tiny micro-channels in the epidermis, a bit like a well, so hyaluronic acid can sit inside and penetrate the skin more effectively", continues Shah-Desai. This means the maximum amount of hyaluronic acid, as well as any other actives in the formula, are absorbed, leading to firmer skin that smooths the appearance of fine lines. Endogenous KGF is a 28 kDa protein produced naturally in the body by dermal fibroblasts within the skin, lamina propria cells of the intestines and, most importantly, mesenchymal cells. Its epithelial cell proliferative properties help to maintain epithelial integrity. 10 The specificity of KGF for epithelial cells is due to its exclusive action on KGF receptors, which are present on epithelial cells and absent on cells of hematopoietic origin. 11, 12 rHuKGF is a recombinant N-terminal truncated form of human KGF prepared from Escherichia coli using recombinant DNA technology. The molecular weight of rHuKGF is only 16.2 kDa, which is smaller than that of endogenous KGF due to the removal of the first 23 N-terminal amino acids with an elimination half-life (t 1/2) of 4.5 hours. 13 It has similar biological activity to the native protein but higher stability. 14 Gromov, P. et al.

BALB/C mice were injected intraperitoneally with LPS (1 μg g −1) to induce an acute phase response and systemic inflammation. Using functionalized microneedle patches, we measured the longitudinal concentrations of mouse IL-6 in ISF, which is known to increase in serum over 4 h after LPS administration 34. Microneedle patches, pre-functionalized with IL-6-capture antibodies, were administered at different time points on mouse ventral skin and left undisturbed for 20 min (as indicated in Fig. 5b). After removing the microneedle patches from the skin, p-FLISA was performed ex vivo to measure the concentration of IL-6. Fluorescence intensity corresponding to the plasmonic fluors on the microneedle patches exhibited a gradual increase from 1 h to 4 h after LPS injection (Fig. 5c), whereas no significant change was observed in mice injected with saline (negative control group) (Fig. 5c and Supplementary Fig. 15). On the basis of the standard curve (obtained using microneedle patches exposed to known concentrations of IL-6), the concentrations of IL-6 in mouse ISF were determined to be equivalent to 2.6 ± 1.9, 12.3 ± 8.6, 120.4 ± 73.4 and 1271.9 ± 393.4 pg ml −1 at 0, 1, 2.5 and 4 h after LPS injection, respectively (Fig. 5d). Specificity tests also validated that other cytokines or chemokines, whose levels might also increase with LPS injection, do not interfere with the detection and quantification of IL-6 on microneedles (Supplementary Fig. 17 and Supplementary Table 2). The IL-6 concentration in sera collected 4 h after LPS or saline injection exhibited good qualitative correlation with that measured in ISF using the microneedle method at the same time point (Fig. 5e). However, the serum IL-6 concentration was found to be nearly 22-fold higher compared to that in the ISF. The absolute concentration of the protein biomarkers in ISF was lower than the concentration in blood, which can partly be ascribed to the difference between microneedle-based analyte sampling method and solution-based standard curve, as well as inherent variation of proteins in body fluids 4. The p-FLISA standard curve, which is used for estimating the concentration of the analyte, was obtained by exposing the microneedle patches to known concentrations of IL-6 in standard dilution buffer. By contrast, microneedle-based ISF sampling occurs in a dense tissue matrix, resulting in slower diffusion kinetics and, consequently, a lower apparent concentration of the analyte. Nevertheless, the analyte concentration determined using the microneedle-based method also exhibited excellent qualitative agreement with the measured concentrations in serum samples (Fig. 5e and Supplementary Fig. 16).

Transcutaneous delivery is the ideal method for delivering therapeutic reagents or vaccines into skin. With their promise of self-administration, cost-effective and high efficiency, microneedle patches have been studied intensively as therapeutic and vaccination delivery platform that replaces injection by syringe. This review aims to summarize the recent advancements of microneedle patches in application for drugs and vaccine delivery. Results can be seen within 20 minutes, making the patches the perfect pre-party beauty buy", explains Henrik Sandstrom, product manager at Swiss Clinic about the brand's Hyaluronic Microneedle Patches. "However, the best possible results will be seen if worn overnight, up to 12 hours, as this will allow the active compounds to fully absorb into the skin."It’s best to see a board certified dermatologist, plastic surgeon, or cosmetic surgeon for this procedure. In some states, an aesthetician may also be able to perform the procedure if supervised by a physician. He, R. et al.
