NIOD stands for Non-Invasive Options in Dermal Science, which is how the store titles itself. The product names are abbreviated chemistry-style labels, so the price list is the quickest way to see how the range is organized. The prices below were read from the NIOD homepage and are listed in US dollars; they can change, and the store may show different options depending on your region.

The two bestsellers

NIOD's landing page flags two products as best sellers. The Copper Amino Isolate Serum 3 1:1 (abbreviated CAIS3) is listed at $74 for 15 mL, and a 30 mL size is also offered. The Copper Amino Isolate Lipid 1% (CAIL) is listed at $112 for 15 mL. Together they sit at the top of the price list.

The rest of the shelf

Here is the rest of what was listed on the homepage, with sizes as shown:

How the prices compare

The cheapest item here is the Enzyme Mist at $28.80, and the most expensive is the Lipid at $112. That is nearly a four-fold gap. Because sizes differ, price per milliliter is not the same thing as price per item: the serum is $74 for 15 mL, while the Hydration Vaccine is $68 for 50 mL. If you are deciding where to spend, compare size as well as sticker price.

A lower-cost sampler

If the top-end serum and lipid are more than you want to spend, the three cheapest items give you a way to try the range: Survival 0 at $31, Modulating Glucosides at $35 and the Enzyme Mist at $28.80. Together they total $94.80 at listed prices, which is still less than the CAIS3 and the Lipid combined.

Availability note

When we read the page, the products were showing as out of stock. Stock status changes often, so check the product page rather than relying on this guide. If something is sold out, many stores offer a restock notification, but that is a feature of the store's site, not something we can promise.

How to pay less

The store's own offers are limited. The ones we track are free shipping to selected countries and a newsletter sign-up offer; neither is a percentage off a product, so they matter most when you are ordering several items at once. Details and any codes that appear are collected on our NIOD coupons page.

If you have sensitive skin or a skin condition, check with your doctor or dermatologist before adding a new active product to your routine.
