Revitalize Your Skin: The Amazing New Serums from Willumina for Aging Skin

As we enter our 50s, skin concerns such as dullness, dryness, and a lack of firmness become increasingly common. Recent studies have shown that one in two women in this age group faces these multifaceted skincare issues. To address these concerns, Willumina, based in Shinjuku, Tokyo, is introducing a groundbreaking serum line featuring beneficial Galactomyces, set to launch on September 2, 2025, in co-op stores and official e-commerce platforms.

Addressing Changing Skin Needs

Willumina's development is rooted in extensive research conducted with 1,045 women. The findings revealed key factors that influence their choices when selecting a serum. Overwhelmingly, participants emphasized the importance of matching the serum to their skin type (38.6%), ensuring it is gentle and non-irritating (24.1%), and feeling effective results (23.7%). Notably, the desire for effective results significantly increased with age: 28.0% of women in their 50s and 30.6% of those aged 70 and older expressed this need, indicating a growing demand for noticeable change in their skincare routines.

Further exploration into the skin concerns of women aged 40 and above showed that many deal with multiple issues simultaneously, including dark spots, sagging, fine lines, and wrinkles. In fact, among women in their 50s, the statistics are alarming: 59.0% struggle with dark spots, 51.5% face sagging skin, 46.3% deal with fine lines, and 41.5% contend with wrinkles. These findings suggest a strong desire for effective solutions in skincare as skin changes inevitably occur with age.

In response, Willumina is committed to offering products that deliver precisely what the skin currently needs, enabling consumers to choose between two distinct options:
1. Galactomyces Liquid 100—a pure, 100% Galactomyces serum designed for those seeking straightforward transparency and efficacy.
2. Galactomyces + β-Glucan Serum—a comprehensive formula for aging skin that aims to address various concerns.

This dual-option strategy not only allows skincare enthusiasts to select a product that fits their current skin condition but also ensures they can find a match that eases any feelings of uncertainty in their skincare journey.
