Source: https://peacockwholesale.io/blogs/cosrx-vs-skin1004-wholesale Author: Amisha, Marketing Manager (Peacock Wholesale) Published: 2026-11-03 Updated: 2026-11-03 Part of: Korean Skincare Wholesale in the USA: 8 Questions to Ask a Supplier (https://peacockwholesale.io/blogs/korean-skincare-wholesale-usa) A reseller's comparison of COSRX and SKIN1004 on Peacock: range size, best-known products, how each range is organized, and which to start with for your customers. ## Key takeaways - Peacock lists 158 COSRX products and 92 SKIN1004 products. - COSRX sells through separate hero products; SKIN1004 builds its range around Madagascar centella. - Most new stores do well starting with COSRX, then adding one SKIN1004 line once the basics sell. Should you stock COSRX or SKIN1004 first? Both are Korean skincare brands built on a short list of well-known ingredients, both sell at accessible prices, and both are easy to reorder. They are organized very differently, though, and that changes how you buy, display and sell them. Here is how they compare for a reseller, using Peacock's current catalog. ## COSRX vs SKIN1004 at a glance ![Comparison table of COSRX and SKIN1004 wholesale ranges on Peacock](https://zkgczounduybqdelytej.supabase.co/storage/v1/object/public/cms_media/blogs/1793237394882-17inw1f.jpg) ## COSRX in short COSRX names its products after their hero ingredient, so the label does a lot of the explaining. The range is a set of separate best sellers rather than one connected system. Peacock currently lists 158 COSRX products, including the Advanced Snail 96 Mucin Power Essence, the Low pH Good Morning Gel Cleanser, Master Patch, the Full Fit Propolis and Hydrium lines, and The Niacinamide 15 Serum. Our [COSRX wholesale guide](/blogs/cosrx-wholesale-guide) covers the range in more detail. ## SKIN1004 in short SKIN1004 builds almost everything around one ingredient: centella asiatica from Madagascar. The core Madagascar Centella products include the Ampoule, the Toning Toner, the Soothing Cream, the Light Cleansing Oil and the Quick Calming Pad. Around that core sit several themed lines, each with its own toner, ampoule, cream and masks. Peacock currently lists 92 SKIN1004 products. - **Hyalu-Cica:** hydration, including the First Ampoule, Blue Serum and Cloudy Mist. - **Poremizing:** pore-focused care, including the Fresh Ampoule, Clear Toner and Light Gel Cream. - **Tea-Trica:** a tea tree and centella line, including the Purifying Toner, Relief Ampoule and B5 Cream. - **Tone Brightening:** the Capsule Ampoule, Capsule Cream and Boosting Toner. - **Probio-Cica:** the Intensive Ampoule in 30, 50 and 95 ml. - **Boosting Shots:** single-ingredient ampoules, such as Niacinamide 10 and Retinol 0.2. ## How they differ for a reseller - **Shelf story:** COSRX sells product by product. SKIN1004 sells line by line, which makes routine bundles easy: a toner, an ampoule and a cream from the same line. - **Recognition:** COSRX best sellers like the Snail 96 essence are well known by name. SKIN1004 is best known for its Madagascar Centella Ampoule, which is the natural entry point to its lines. - **Add-ons:** COSRX has patches, minis and trial sets. SKIN1004 has a travel kit for most of its lines, which works well as an introduction or gift. - **Range depth:** SKIN1004 is the smaller range, so it is easier to stock one complete line without tying up cash. ## Which one to stock first - **New store, mixed customers:** start with COSRX. Its best sellers are easy to explain and easy to reorder. - **Store with a calm, minimal skincare focus:** start with SKIN1004's core Madagascar Centella products and one themed line. - **Already carry COSRX:** add one SKIN1004 line, such as Hyalu-Cica or Poremizing, rather than more COSRX variations. - **Building bundles or gift sets:** SKIN1004's matched lines and travel kits make this simple. ## Common mistakes to avoid - **Buying every SKIN1004 line at once:** each themed line looks small, but together they spread your budget thin. Start with one. - **Skipping the core COSRX products:** newer COSRX lines are fun to test, but the best-knowns usually carry the reorders. - **Mixing versions:** some listings name a market version, such as Global Ver. Check before you reorder so your listings stay consistent. - **Pricing every product the same way:** ampoules, toners and travel kits do different jobs. Price hero products, add-ons and gifts differently. ## Stocking both You don't have to choose. Peacock's minimum is set per order, not per brand, so one order can combine COSRX best sellers with a single SKIN1004 line. A simple split: a handful of COSRX hero products, plus the SKIN1004 Ampoule, Toning Toner and one travel kit. Let reorders show you which brand your customers come back for, then go deeper there.
