Combatting Spring Skin Sensitivity
The arrival of spring often ushers in a period where the skin’s natural barrier function is easily disrupted. External aggressors like pollen and PM2.5, coupled with the internal stress from sudden temperature changes affecting the autonomic nervous system, can lead to increased dryness and sensitivity. This makes a dedicated skincare routine more crucial than ever.
STLASSH’s answer lies in their “HADATERASU RADIANT” series, formulated with precious “amniotic fluid extract¹” (a moisturizing ingredient) and human-derived stem cell culture fluid. These ingredients are chosen for their gentle yet effective support, making the series suitable for a wide range of skin types, even during periods of sensitivity. It’s like wrapping your skin in a gentle, protective layer against the spring elements.

Deep Dive into the HADATERASU RADIANT Series
The “HADA TERASU RADIANT” series, whose name signifies “emitting light” and “shining brightly,” is designed to help users achieve a luminous, clear complexion. The Essence Lotion utilizes highly pure “ultra-pure water” to ensure moisturizing ingredients penetrate directly into the stratum corneum. It’s oil-free and additive-free, making it exceptionally gentle for delicate skin.
The Bubble Essence offers a novel experience, transforming into micro-bubbles upon application. These fine bubbles deliver moisture deep into the stratum corneum, promoting a translucent, firm complexion. It’s an intensive care serum highly recommended for those concerned about dryness and dullness².

STLASSH: Pioneering Integrated Beauty
STLASSH, established in 2015, has grown to 62 women-only hair removal salons across major Japanese cities. With over 3.14 million treatments and 330,000 members, STLASSH is renowned for its commitment to convenience and skin kindness. Their unique “Elepore Hair Removal” (electroporation hair removal) system, often called “needle-free Potenza³,” combines hair removal with advanced skincare. This innovative approach uses special electrical pulses to deliver moisturizing ingredients like amniotic fluid extract, CICA, and glutathione into the stratum corneum, allowing members to achieve beautiful skin while removing unwanted hair.

As one beauty enthusiast shared, “Spring often feels like a battle for my skin, so a dedicated skincare routine like this is a true lifesaver for maintaining that coveted clear, radiant look.” This sentiment perfectly captures the essence of STLASSH’s campaign: empowering individuals to feel confident in their skin, regardless of the season.
³ “Needle-free Potenza” is a descriptive term for a beauty device-based skincare treatment and differs from the medical procedure “Potenza.”
STLASSH continues to support individual beauty through their salon-quality skincare series, “HADATERASU,” ensuring a comprehensive approach to achieving “tsuru-mochi” (smooth and plump) skin. Their commitment to integrated beauty, combining efficient hair removal with advanced skincare, sets a new standard.
