How US Med Spas Can Buy Korean PDRN & Exosome Skin Boosters in Small Quantities

Quick answer

  • You can buy finished Korean skin boosters (PDRN, exosome, NAD+ and peptide ampoules) direct from a Korean manufacturer, from 1 unit per SKU.
  • Choose a supplier that ships to the US DDP (Delivered Duty Paid), so import duties are prepaid and nothing is charged on delivery.
  • Stick to topical cosmetic boosters used with microneedling or facials. Injectable "skin boosters" are a different, regulated category.
  • At KINN: free account to see prices, 3+ items 23% off, EMS or DHL from Busan in 7–21 business days, card or PayPal at checkout.

Korean skin boosters have become a staple in med spa menus: PDRN (salmon DNA) for recovery-focused facials, exosome ampoules for glow treatments, and peptide or NAD+ ampoules for firming programs. The problem for a small med spa is usually not demand. It is buying in small quantities without paying distributor mark-ups, and without surprise fees when the parcel reaches the US.

This guide explains how small US clinics can buy Korean skin boosters directly, what to check before ordering, and how landed cost works after the end of the US de minimis exemption.

1. Decide what you actually need: topical boosters, not injectables

"Skin booster" is used for two very different product types:

  • Injectable skin boosters (for example hyaluronic-acid or polynucleotide injections). In the US these are regulated medical products and are outside the scope of a cosmetics supplier.
  • Topical skin boosters: cosmetic ampoules and serums applied to the skin, often during or after microneedling (MTS) or as part of a professional facial. This is what most med spas and estheticians buy from Korea.

KINN supplies topical cosmetics only. If a supplier offers you "injectable" products by mail with no paperwork, treat that as a red flag. Your local regulations decide how each product may be used in your clinic, so confirm protocols with your medical director or regulatory adviser.

2. Know the main product formats

  • Skin booster ampoules: single-use vials (2–10 ml, usually 5 or 10 per box). One vial per session, high concentration. Best for treatment menus priced per session.
  • Microneedling (MTS) serums: 50 ml bottles on a hyaluronic base, used across many sessions. Lower cost per treatment.
  • Freeze-dried booster kits: a powder or cube vial mixed with its activating solution right before use, so delicate actives stay at full strength.

Popular actives to look for: PDRN (salmon DNA) and polynucleotides, exosomes and stem-cell conditioned media, peptides and NAD+ and NMN.

3. Buy direct from the manufacturer, in small quantities

Most Korean factories quote minimums of 1,000 to 10,000 units because they make products to order. That is private label, not what a single clinic needs. What you want is a manufacturer that also sells its finished products as-is, in small quantities.

How ordering works at KINN:

  1. Create a free account. Prices are shown to registered buyers.
  2. Add what you want to test. Most products start at 1 unit per SKU, and you can mix any products in one order.
  3. Order 3 or more items and 23% is taken off automatically at checkout (DERMAEL home-care items use carton pricing instead).
  4. Pay by credit or debit card (processed by PayPal, no PayPal account needed) or by bank transfer for larger orders.
  5. Your order ships from Busan by EMS or DHL Express with tracking.

4. Landed cost: why DDP matters in the US now

Since the US ended its duty-free de minimis treatment for low-value parcels in 2025, imported cosmetics generally owe duty no matter how small the shipment. With many overseas sellers the price you pay at checkout is not the final price: duties and a courier brokerage fee are billed to you when the parcel arrives (DAP terms).

With DDP, the seller prepays duties and customs clearance. KINN ships every US order DDP: US prices already include import duties, so the checkout total is what you pay, and there is nothing to pay on delivery. Shipping is calculated by weight and shown at checkout before you pay. Orders to other countries ship DAP.

When you compare suppliers, compare the total landed cost (product + shipping + duties + fees), not the product price alone.

5. Documents to ask for

  • COA (certificate of analysis) and MSDS/SDS: KINN includes both with every shipment.
  • The manufacturer's ISO 22716 (cosmetic GMP) certificate.
  • A full ingredient list and label artwork if you plan to resell retail units. Check US labeling requirements before reselling.
  • For larger contracted orders, a country-registration package (Free Sale Certificate, ingredient report, lab test report).

6. A quick supplier checklist

  • Is it the manufacturer or a reseller of other brands?
  • Is the minimum order realistic for a single clinic (1 to 10 units)?
  • Are US orders shipped DDP, or will duties be billed on delivery?
  • Are the products clearly topical cosmetics?
  • Do you get COA and MSDS with the shipment?
