Problems solved by technology

While these methods call for increased penetration of skin care actives into the skin, they still do not provide enhanced penetration in a controlled manner - both based on penetration volume and penetration depth

Embodiment 1

[0138] Example 1: In vivo skin penetration study of Pal KTTKS

[0139] Pal KTTKS enhancement from cream (w / vibration versus w / o vibration)

[0140]

[0141]

[0142] "S" indicates passive (p <0.1) significant difference from the average

[0143] An in vivo skin penetration study was conducted to determine the effect of using the skin care product of the present invention by applying a skin care composition including a peptide, in this case, the peptide is Pal KTTKS, wherein the application device includes a magnetic array and a vibration source. The study used 10 active study sites (the composition applied to the target skin surface using the application device containing the magnetic array and vibration source of the present invention) to 10 control study sites (the application device with only the magnetic array was applied to Target skin surface composition). In this example, HPLC was used to measure the PalKTTKS content present in the extract from each tape strip, and the res...

Embodiment 2

[0148] Example 2: In vitro skin penetration study of inositol (see Image 6 )

[0149] Franz diffusion cell analysis was used to measure skin penetration. Thaw the human cadaver skin of layered thickness (dermatosis) under environmental conditions, cut into slices of appropriate size, and install it in a standard Franz diffusion cell (0.79cm) maintained at about 37°C 2 Surface area) in. The receptor compartment was filled with 5 mL of phosphate buffered saline solution (PBS-pH 7.4), which included 1% polysorbate-20 and 0.02% sodium azide, and the skin was allowed to equilibrate for two hours. Diffusion cell in 3 H 2 Passes when 0 flux passes through the installed skin (150μL 3 H 2 0, apply for 5 minutes and remove; collect receptor fluid after one hour and analyze using scintillation spectroscopy). The diffusion cells were randomized by sorting each cell according to water flux and spreading the cells over the treatment legs so that each group included a pool that spanned the r...

Abstract

An applicator for a skin care product is provided, together with a cosmetic skin care product comprising an applicator and a skin care composition, and a method of using the applicator to regulate a skin condition are provided. The applicator has a substrate with a magnetic array printed thereon, the magnetic array having at least one layer of one or more dipolar pairs of alternating magnetic poles. The applicator further has a vibration source. The magnetic field strength generated by the magnetic array is at its maximum at the poles. When activated, the vibration source causes side to side movement of the applicator, meaning that the full magnetic field is experienced by all diamagnetic materials to which the applicator is applied.

Description

Technical field [0001] The present invention relates to an applicator for skin care products that provides enhanced penetration of skin care actives into the skin; and a method for enhancing the delivery of skin care actives into the skin. Specifically, the present invention relates to an applicator that combines the beneficial effects of diamagnetic and vibration to optimize the penetration of skin care actives into the skin. Background technique [0002] Topical skin care compositions containing active substances that provide beneficial effects to the skin are known. For example, vitamin B3 compounds, especially niacinamide, are known to provide measurable skin conditioning benefits. Topical niacinamide is known to help regulate the signs of skin aging by reducing the visibility of fine lines, wrinkles, and other forms of uneven or rough surface texture associated with aging or photodamaged skin. These compounds have also been found to reduce the overall oiliness of the skin....
