Which Medicube Exosome Shot Should You Buy? Spicule and Peel Shots Compared

By the Medicube Picks editorial team · product data refreshed 30 October 2026 · how we rank

We have not tested the products in this guide. Everything here is read from the listings, the published ingredient lists and what buyers report, not from hands-on use. What that means.

Which Medicube exosome shot should you buy, and what does the PPM number on the bottle mean? Medicube sells two kinds of shot: spicule serums, the Exosome Shots, which carry microscopic needle-shaped particles you feel as a prickle, and peel shots, which use acids or hypochlorous acid on the face and body. This guide compares every Medicube shot we track, reads each published ingredient list for spicules, declared exosome strengths and acids, and tells you who should skip them.

We track 10 Medicube exosome and peel shots on Amazon.com; 10 of them have a full published ingredient list, and every list-based figure below comes from those.

What does the PPM on a Medicube Exosome Shot mean?

The ingredient list does not say. In the product name the figure sits next to the word spicule and rises from the mildest version to the strongest, so read it as the brand's strength scale for the spicule prickle rather than as an exosome dose. If you want one to start with, these are the best-rated shots for each job:

Where the spicules and exosomes sit in each Medicube shot

5 of the 10 Medicube shots with a published list carry hydrolyzed sponge, the spicule ingredient; the rest are acid or hypochlorous acid peels with no spicules on the list:

Where a list declares an exosome strength, it is between 10 and 154 ppm, and none of those figures matches the PPM number in a product name. A ppm is one part per million, so these are small amounts by design.

What a spicule serum is and how it feels

A spicule serum is a serum carrying hydrolyzed sponge, listed by that name: microscopic silica needles from a sponge that lodge in the top layer of skin as you massage them in. That is the prickle you feel, which can last from minutes to the next day, and it is the point of the product. Medicube says the spicules help what goes on next absorb better.

That makes a spicule shot closer to an exfoliating treatment than to an ordinary serum, and it should be used like one: in the evening, a few times a week at most, on skin that is not already irritated.

Exosome shot or peel shot: the difference

The difference between an exosome shot and a peel shot is how they work. Exosome shots work physically, with spicules; peel shots work chemically, with acids such as salicylic acid and gluconolactone, with kojic acid, or with hypochlorous acid. Both are sold for texture, pores and dullness, and both count as exfoliation when you plan the rest of your week.

The body versions apply the same idea to rough, bumpy skin on the arms, legs and back, where skin is thicker and usually tolerates more.

How to use a Medicube exosome shot safely

Use a Medicube exosome shot in the evening on clean, dry skin: massage a small amount in until the prickle starts, then follow with a plain hydrating serum or cream. Start with the lowest-strength version twice a week and move up only if your skin settles within a day.

Keep shots away from retinoids, acid pads and other peel products on the same night. Stop if the prickle turns into burning or the redness lasts into the next day, and skip spicules altogether on broken, sunburnt or inflamed skin and if you have rosacea.

Who should skip which Medicube exosome and peel shots

Every product we read in full has a note on who it does not suit. These are the notes for the exosome and peel shots not picked above:

Common questions

Does the Medicube exosome shot hurt?

It prickles, and that is intended. The sensation comes from the spicules and usually fades within minutes to hours. Burning, or redness that lasts into the next day, means stop and give your skin a week off.

Is a higher PPM Medicube shot stronger?

Within the same line, the higher number is sold as the stronger version. The lists do not define what the figure measures, so compare versions by where the spicules sit and what else is on the list, which the table above shows.

Can you use an exosome shot every day?

Not as a starting point. Begin at two evenings a week and treat the shot as the exfoliating step of your routine on those nights.

Can you use an exosome shot with retinol?

Not on the same night. Spicules on top of a retinoid stack two kinds of irritation, so alternate them on different evenings.
