acosmeticstory Korean skincare cores and holders compatible with a range of Core containers
Holders
Choose what you keep.
Core and Holder Compatibility One attachment system across Ju, Sai.
Every Core connects to Ju, Sai-S and Sai-M through the same attachment system. Keep the Core you choose, then select a Holder by form, proportion and feel.
Independent Object Independent objects, designed to be used over time.
A Holder is not simply another cosmetic container.
It does not directly contain the formulation, nor is it tied to a specific formulation or a single Core.
While the Core delivers contents and information, the Holder shapes the experience of use, storage, touch, form, choice, and ownership.
When the Core changes, the Holder remains. When the Holder changes, the same Core can continue to be used.
Two Types. One Hundred Fifty Holders.
Holders come in two types, Ju and Sai. Because a Sai expresses itself differently depending on the height of its cylinder, it is currently offered in two heights, S and M.
Ju, Sai-S and Sai-M each carry fifty colorways, one hundred fifty Holders in all. Within the same type, caps and bodies can be swapped, so the choice does not end at one hundred fifty.
A Holder is not an accessory that must be redesigned whenever a new Core is created. It is an independent product family with its own design language and manufacturing philosophy.
Its value grows through the relationship it builds over time.

Discover what fits you.
Chapter 1. Intrinsics Thirty different creams. So you can understand the differences and choose what suits you.
Intrinsics are a collection of Korean skincare creams, thoughtfully researched and precisely developed by TangibleStory and COSMAX.
Each Intrinsic has its own formulation, with a distinct ingredient list, texture, hardness, pH, purified water content, and formulation type.
The way a cream feels is personal. The same Intrinsic can be experienced differently from person to person, and across seasons, places, and moments of use.
The ingredients and physical information of each Intrinsic provide a consistent point of reference for understanding and comparison. These published specifications remain the standard for each Intrinsic for as long as it is available.
Numbers and ingredients do not always explain what those differences might mean to you. With personal AI that can work with your own context, you can explore the information, compare Intrinsics, and make sense of those differences for yourself.

7g, 15g, or 30g. Start with the amount you choose.
Physical Language A shared language for genuine differences.
Cosmetics are often described in emotional language that can mean different things to different people.
Physical Language adds comparable physical information: full ingredients, hardness, pH, water content, formulation type, and details of form and appearance.
This physical information is a shared language for understanding and comparing products as they are.
It helps people recognize the genuine differences between Cores and set clearer criteria before choosing.
Graphic ID Physical characteristics translated into a visual language.
Graphic ID translates physical characteristics such as texture, flow, viscosity, and structure into a visual language.
It helps people observe and compare formulations beyond emotional imagery alone.
Personal AI Explore structured Core information with the AI you choose.
Each Core presents its ingredients and physical properties in a structured form that can be explored with the AI service a person chooses.
AI can explain terms and offer possible interpretations in context, while the final decision remains with the person.
