Olive Young's Skin Diagnosis Has Moved Into the App

What is the signal?

On 15 September CJ Olive Young opened a mobile skin diagnosis service that measures skin condition with a smartphone and recommends how to care for it. It implements inside the Olive Young app the experiential beauty service Skin Scan that the company has run in major stores nationwide. The company described the extension as experiential beauty stepping outside the store, and positioned it as widening the omnichannel shopping experience.

The way it works is simple. After a short questionnaire in the app, the user photographs their face or selects a photo they already have, and AI returns results broken out by category: skin type, pores, pigmentation, hydration, sebum, wrinkles. Products and a personalized skincare routine are then recommended based on that result. The differences the company emphasized are that no store visit is needed, and that users can measure again whenever they want, observing how their skin changes with the season, their habits and the products they are using.

Planned additions were disclosed alongside it. Olive Young said it will add a skin change report that tracks how skin shifts over time, product recommendations that reflect existing care habits, and personal color diagnosis within the year. Earlier, in December 2025, cumulative Skin Scan usage passed one million; at that point the service was running in around 60 stores nationwide, with a stated plan to expand past 100 stores the following year. The intent to widen the scope to a scalp diagnosis service, Skin Scan Scalp, and personal color measurement was also announced then.

That said, all of this is a service description released by a retailer, not performance data. How many people have used the mobile diagnosis, and how much purchasing follows a recommendation, have not been disclosed, and no material verifying the accuracy of photo-based analysis was released with it. So the signal is better read not as an answer to how well personalization sells, but as the fact that Korea's largest beauty retail channel has placed one more layer, a diagnosis screen, between customers and products.

1. When diagnosis comes first, product information becomes a category rather than a search term

Until now, the usual route to discovery in Korean beauty has been the search term. Customers typed words like 'pores' or 'moisturizer' themselves, and brands tuned product names and detail pages to catch those words. When diagnosis comes first, the order reverses. The customer does not choose the words; the system produces results by category and then shows products matched to them.

What that calls for is not a better search term but a clear statement of which category a product answers to. A product that speaks to 'skin concerns in general' does not attach strongly to any category. A product aimed clearly at one category, by contrast, lands naturally in front of the customer whose result points there.

So what has to be settled at the planning stage is not a concept sentence but the category the product addresses. Write down whether this product handles sebum or hydration, and if both, which comes first, and the explanation holds even when the channel changes.

• Have you narrowed the categories this product addresses to one or two, in writing?
• Do the product name and detail page use the same vocabulary as that category?
• In trying to speak to several categories, has the product ended up distinct in none?

2. Six categories make you look again at your lineup

The analysis categories disclosed are skin type, pores, pigmentation, hydration, sebum and wrinkles. Lay your brand lineup over those categories and the empty cells and the crowded ones both appear. If you have three or four hydration products and nothing addressing pores or pigmentation, it means the products you can show are clustered on one side no matter which way the diagnosis comes out.

Where several products stack on one category, they end up dividing that space among themselves inside your own brand. In that case the customer needs to see what separates them: price band, moment of use, or texture. Without that distinction, the recommendation screen gives no reason to choose.

This does not have to be solved by adding lines. In many cases, simply rewriting existing product descriptions to line up with the categories reduces both the overlaps and the gaps. Before making one more new product, drawing where your current products sit costs less.

3. Re-measurement favors products that show change

One of the features Olive Young emphasized is that users can measure again whenever they want, observing how skin changes with the season, their habits and the products they use. The skin change report planned within the year points the same way. This is not a structure where you diagnose once and finish; it is built to bring people back after time has passed.

The products that gain in this structure are not the ones that feel good immediately, but the ones where the customer can confirm for themselves that something has changed after a period of use. That requires a clear usage cycle. The product has to say how many times a day and over how many weeks it is used before the customer can pick a moment to measure again.

Volume design hangs on this too. If the recommended usage period and the volume actually in the container do not match, the customer either finishes the product before they can confirm a change, or forgets it without finishing. Writing the usage cycle and the volume on the same line of the brief reduces that mismatch.

• Does the recommended usage period match the product's volume?
• Does the product tell the customer when to check again?
• Are the repurchase point and the recommended usage period designed as the same number?

4. A routine recommendation asks about combinations, not single products

The service does not only recommend products; it proposes a personalized skincare routine alongside them. A routine is not one product but an order. What comes after what, and what does not overlap with what, is the substance of the proposal.

That changes what a brand has to prepare. Material explaining the merits of a single product cannot describe its place inside a routine. You need to have set out where this product falls after cleansing, and what order it takes when used with other products from the same brand.

You also have to assume it may sit beside other brands' products. A retail channel's recommendations are not bundled by brand. Whether your explanation still holds when your product is wedged between someone else's is the real test.

5. Online diagnosis and the offline shelf have to use the same words

Skin Scan began as an in-store service and now runs under the same name in the app. A customer can be diagnosed in a store and measure again in the app, or look first in the app and then pick a product in a store. The channels are separate, but the customer's memory is continuous.

This is where wording most often diverges. When the online detail page, the shelf description in store and the copy on the package all use different words, the customer reads one product as several. It is worth checking whether they are unified around the same vocabulary as the diagnosis categories.

The package is the slowest element to change. A detail page can be fixed in a day, but containers and cartons only change once existing stock is used up. So it is better to settle the vocabulary before finalizing package copy, not after fixing the detail page.

The first question for the brief

Write this on the first line of the brief: which category of the diagnosis result does this product sit in, and what should be different when the customer looks again a few weeks later? On a screen where diagnosis comes first, a product whose place is clear is seen before a product that is merely well made.
