New HADAYOHOU Abirudake Serum Lets You "Bathe" in Anti-Aging Care with a Single Mist

Ventuno Co., Ltd., the company behind the "KAISO" line of seaweed-based skincare, is adding a new collection to its lineup. HADAYOHOU, a concept built around "predicting the future of your skin and caring for it in advance," debuts with its first product: HADAYOHOU Abirudake Serum.

The serum went on sale on Amazon on June 24 and on Rakuten Ichiba on July 1. Pre-orders opened on Rakuten and Amazon from June 2, and by the time general sales began, the product had already climbed to number one overall in Rakuten Ichiba's real-time ranking, updated June 26 at 7:39 AM.

Product Overview

A Mist Serum Designed to Simplify the Routine

Mist-format beauty serums built specifically for anti-aging care are still uncommon, and HADAYOHOU Abirudake Serum leans into that format to cut down on effort. Instead of opening a bottle, pouring serum into your hands, and smoothing it over your face, the entire step is condensed into a single spray.

In place of purified water, the formula is built on a fermented rice liquid base, with beauty ingredients making up roughly 99.4% of the formula (excluding purified water). Even though it's a mist, the texture is designed to feel like a rich, concentrated serum.

The bottle uses a specialized pump that generates nanobubbles smaller than 1 nanometer in diameter with just a shake — far smaller than the roughly 300-micrometer pores on skin. The idea is for these fine bubbles to help carry the beauty ingredients deeper into the stratum corneum, which is also why the brand positions the mist as a booster step before the rest of a skincare routine.

The formula combines niacinamide, retinol, PDRN, and CICA, ingredients aimed at addressing age-related skin concerns such as dryness, loss of firmness, and dullness.

The HADAYOHOU Concept

HADAYOHOU is built around forecasting how skin will change and getting ahead of it with proactive care, under the tagline "predict the future of your skin, and get ahead of it — turn tomorrow's skin into a clear sky."

The Abirudake Serum marks the first release under this new line from Ventuno, a company that has spent more than three decades researching seaweed-derived ingredients such as fucoidan from mozuku and mekabu seaweed.
