Shiseido reveals skin translucency research


Shiseido has taken the wraps off its research into the behaviour of light on the skin, including how light emissions decrease with age. Working with the Muroran


Institute of Technology, Shiseido has developed the world’s first optical measurement system capable of non-invasive measurement and analysis of three-dimensional facial shape and optical conditions. In pursuit of achieving skin


translucency, Shiseido’s optical research focused on how light incident on the skin penetrates the stratum corneum, reaches the dermis, and again exits the skin’s surface (subsurface scattering light). Measurement and analysis


results revealed that short- wavelength light reaches the epidermis, mid-wavelength light reaches the area from the epidermis—centred around the basement membrane—to near the upper dermis, and long-wavelength light reaches the collagen layer of the dermis before it is re-emitted from the skin’s surface. Furthermore, as short-


wavelength light reaches the The results revealed that reduced


collagen density decreases the amount of light reaching the dermis and emitted from the skin’s surface. These findings demonstrate that melanin levels in the stratum corneum and the epidermis, along with dermal collagen density, are essential for skin translucency. Furthermore, using the optical


epidermal layer, non-invasive measurement and analysis of the relationship between melanin level and light reaching and emitted from the epidermal layer revealed that melanin is significantly involved in light absorption. Melanin blocks light, making


it difficult to penetrate the skin, thereby reducing the amount of light emitted from the skin’s surface. Additionally, as long-wavelength


light penetrates the dermal collagen layer, Shiseido applied the internal and external skin elasticity 3D imaging system that visualizes both inside and outside the skin and enables non-invasive observation of collagen status in living human skin, to evaluate collagen fibre density and analyse correlation.


measurement system, Shiseido applied a newly developed evaluation technique to approximately 150 women aged 20s to 70s, while simultaneously acquiring vast amounts of data through its proprietary non-invasive skin measurement technology. Examination of the parameters influencing light emission at different penetration depths demonstrated that light reaching the epidermis and re-emitted from the skin’s surface is most strongly influenced by absorption by epidermal melanin. Furthermore, light reaching the dermis and re-emitted from the skin’s surface is associated with multiple factors, among which the influence of collagen fibre density is also significant.


Sunjin passes latest US FDA inspection


South Korea’s Sunjin Beauty Science has successfully passed a second United States Food and Drug Administration (FDA) inspection. The company’s core products,


UV filter materials, are classified as functional cosmetic ingredients for OTC drug use in the US are essentially recognized as major Active Pharmaceutical Ingredients (APIs).


The FDA conducts thorough


on-site inspections of manufacturing facilities and quality systems—not only within the US, but also at overseas manufacturers. In 2019, Sunjin passed its first


FDA inspection, supported by proprietary plant design and robust quality systems. Sunjin recently received from the


FDA an Establishment Inspection Report reaffirming its capabilities under even stricter standards for the second inspection. All of Sunjin Beauty Science’s

inorganic UV filters are manufactured on a top-down closed production line optimized for APIs. This system requires significant


capital investment and mandates that more than 30% of the total production workforce be dedicated to quality-related roles such as QA and QC, resulting in higher manufacturing costs. “We’re honoured to announce


that Sunjin Beauty Science has officially passed its second US FDA inspection — becoming the only company in Korea to do so twice in a row,” said a Sunjin spokeswoman.


“This successful inspection once


again officially confirms that our inorganic UV filters are produced in top-tier manufacturing facilities that meet the FDA’s Good Manufacturing Practice (GMP) requirements,” she added. In a related development, Sunjin


Beauty Science has unveiled its expanded Sunjin Clinical Research Centre (SCRC) in Seoul, Korea. Following months of investment


and innovation, SCRC now operates with a five-times larger space; SCRC-exclusive technologies & AI-powered Raman spectroscopy; deepened collaboration with top- tier medical professionals; and full- spectrum efficacy and safety testing — all in-house. The centre can measure many


different types of skin analysis, including skin density, hydration, keratin, wrinkles, lifting, tone, texture, barrier, pigmentation and others.

Korean exports hit $11bn record high


South Korea’s exports of cosmetic products reached a record high of $11.43 billion in 2025, up 12.3% on a year earlier. Seoul’s Ministry of Food


and Drug Safety said Korean cosmetics were shipped to 202 countries last year, up from 172 the year before. The United States was


Korea’s largest export destination, accounting for $2.2 billion in shipments. China followed with $2


billion, while Japan imported $1.1 billion worth of Korean cosmetics. While exports to the


United States and China still dominated, their combined share fell to 36.7% from 43.1%, reflecting diversification into Europe, the Middle East, South and Southwest Asia and Latin America. Shipments to the United


Arab Emirates and Poland showed particularly strong growth. By product category, skin


care accounted for the largest share, with exports totalling $8.54 billion, or nearly 75% of the total.


Exports of skin care, colour


cosmetics and cleansing products all rose by more than 10% from a year earlier. The ministry attributed the


growth in part to regulatory support for exporters, including international regulatory forums, bilateral cooperation, export guidance, training on overseas approval processes and halal certification consulting. It also cited efforts to


streamline domestic regulations to shorten product launch timelines.


The ministry said it would


gradually introduce a safety assessment system aligned with markets like the US and China.
