Shiseido designs new technology to measure ingredient penetration on skin

Cosmetics manufacturer Shiseido has developed DESI-MSI, a new technology to exhibit the state of penetration of cosmetic ingredients through the skin after application in terms of depth direction.

The Japanese firm said it has developed 4MSK, a new whitening ingredient to measure the state of permeation into the skin, reports cosmeticsdesign.com.

Shiseido aims to apply the new technology in creating cosmetics, including developing cosmetic products with even stronger permeation strength, as well as in the field of research and amount of active ingredients penetrating into the skin.

The firm said it initially focused on ‘tape stripping’, which has been a common analysis method that was developed.

DESI-MSI is a recently developed mass spectrometry method, which can quantitatively measure two-dimensional distribution of a number of ingredients simultaneously.

Shiseido, by using multiple 2D distribution data collected via DESI-MSI, also developed a technology for quantitative and clear visual display in terms of depth direction using a newly devised patent-pending data processing method.

The cross-sectional visual display developed currently provides approximated images via data processing, which combines planar images.

Shiseido claims that the new technology can analyse multiple ingredients at the same time in a single measurement process.

The firm said the technology has been applied as a method to measure the penetration strength of "4MSK", an effective whitening ingredient in Shiseido White Lucent Power Brightening Mask to be released from 1 February 2013.
