How COSRX runs UGC: 43 creator accounts, sampled

COSRX UGC program in numbers

Every figure counts the 43 confirmed and likely accounts. View figures come from the 35 sampled TikTok videos only and are lower bounds; Instagram view counts are not public.

What the sample shows about COSRX's program

A sample can show who the creators are and how their posts are marked. It cannot show how often they post or how the whole program performs, so those numbers are left out rather than estimated.

• Established creators, not new accounts. The median creator has 138K followers and 22 of 43 with a known count have over 100,000. COSRX works with people who already have an audience.
• A program hashtag ties the creators together. 43 of 43 counted accounts used the program hashtag (#cosrxpartner on 45 posts).
• Creators on both platforms. We attributed 33 accounts on TikTok and 10 on Instagram. That split reflects how deep each search went, not the program's real platform mix.
• The program is live. 20 of the 45 sampled posts were published in the 90 days to 28 October 2026, the latest on 27 October 2026. The search included a last-month pass, so this shows the program is active, not how often creators post.
• Sampled TikTok videos drew a median of 49K views. The 35 sampled videos drew 31.1M views between them and 15 videos passed 100,000. That is a lower bound on the program's reach, not its total.

COSRX's per-video pay is not public. For typical rates by creator size, see our UGC rates benchmarks.

Who the creators are

Follower counts are each account's public count on 28 October 2026. 93% of accounts with a detected language post in English. Of the 33 accounts with a known location (mostly TikTok post locations), 55% posted from the United States.

How COSRX creators mark their posts

Across the 45 sampled brand posts, the most common marker is program hashtag (100%). Of the posts that carry a program hashtag, 76% also carry #ad, #sponsored or a platform paid-partnership label. The search looked for these markers, so read the mix as which signals creators use, not as a disclosure rate.

COSRX's creators are easiest to find by the program hashtag: 43 of 43 counted accounts used one. The brand name alone never attributes an account, because brand names collide with common words, other products and personal names. US rules on this are summarised in FTC disclosure and paid partnership; program hashtags across 61 brands compares naming conventions.

Format and caption hooks in the sample

The most common length of the sampled TikTok videos is 60 seconds and over (49% of 35 videos with a known length), and 0 are slideshows. By caption, the leading hook types are question (18%) and routine, food or workout moment (11%), across 45 sampled posts. With a sample this size, read these as the shape of the program rather than precise shares.

Hook type is classified from the opening line of each caption. On-screen text and the spoken hook are not public data, so this is the caption hook only. For how hooks are scored in paid social, see hook rate, or draft your own with the UGC hook generator.

Where the data is thin

• This is a sample, not a census: 35 TikTok videos and 10 Instagram posts. Most accounts were read for one or two brand posts, so posting cadence, active accounts, hit rate and dedicated accounts are not reported on this page.
• View figures are lower bounds: public view counts on the sampled TikTok videos only. Instagram hides view counts from logged-out visitors, so Instagram posts carry no view figure. That is unknown, not zero views.
• Posts were found by searching for paid markers (#ad, paid-partnership labels and program hashtags), so the marker mix on this page shows which markers creators use, not how often the brand's creators disclose.
• Web search surfaces bigger, more-viewed accounts more readily than small ones, so this sample likely over-represents established creators compared with a full scan of the program.
• The oldest brand post in the sample is from April 2025. The program may be older; this is the earliest post we found, not a launch date.
• 11 more accounts mention COSRX without a program marker. They are listed as "possible" in the app and left out of every number here.
• COSRX's per-video pay is not public, and public view counts include any paid boosting.

Method

UGC Agent searched the public web for TikTok videos that carry COSRX's program hashtags or tag @cosrx with #ad, #sponsored or a paid-partnership label, read 35 TikTok video pages from counted accounts, and searched Instagram for posts that tag @cosrx with the same markers. A language model screened each post for a paid relationship with this brand and removed other companies with the same name. Every account was then scored on public evidence with the same confirmed, likely and possible rules used across the dataset, and only confirmed and likely accounts are counted.

The fully scanned brands in the dataset read up to 40 recent videos per account and report complete 30-day windows. COSRX was measured from a sample instead, which is why this page reports creator size and markers but no cadence, activity or total views. Read the full rules in the dataset method.
