Can I use VT Reedle Shot every day?

Only the 100 (and the Mild 50) are meant for daily use. VT says the 300 can be used every 3 days and the 700 every 7 days. Even with the 100, VT suggests starting at two to three evenings a week and building up.

Should I start with Reedle Shot 100 or 300?

Start with the 100. VT's FAQ says most first-timers begin there, especially with sensitive or reactive skin, and frames the 300 as the step up for skin that has built tolerance.

Can I use retinol with Reedle Shot?

Not on the same night. VT suggests alternating nights when you use Reedle Shot alongside strong actives like retinol, and the same caution applies to strong acids.

Is the stinging from Reedle Shot normal?

A mild, brief tingling is normal, and VT says it usually fades within a minute. Stinging that lingers or redness that lasts into the next day means you should use it less often or drop to a lower number. More sting does not mean better results.

When do I apply Reedle Shot in my routine?

First, on clean, dry skin right after cleansing. VT's FAQ also allows it after toner. Pat it in with your fingertips, then follow with a simple serum and moisturizer, and wear SPF 30 or higher if you use it in the morning.

VT Reedle Shot 100 vs 300 vs 700: How to Use Each One

The 700 is the bottle a lot of people reach for first. It is also the one most likely to make them give up on spicules. The number on the label reads like a strength rating. VT's own product pages treat it as a schedule — and that changes how to use VT Reedle Shot entirely.

If a Reedle Shot sits on your shelf, used a few nights and then forgotten because all it did was sting, the product may not be the problem. The problem may be how often you are using it. Here is how to use it the way the brand intends: what the 100, 300, and 700 actually mean, which one is yours, and the few rules that decide whether it works.

VT Reedle Shot 100 vs 300 vs 700 — what the number on each bottle means for how often you use it

What the Number on Reedle Shot Actually Means

Every Reedle Shot is built on the same idea: VT's Cica Reedle, microscopic spicules suspended in a Centella and hyaluronic acid formula. The number tells you how many of those spicules are packed into the bottle. The label prints the count — 95,000 in the 100, 237,500 in the 300, and 570,000 in the 700 — and that count sets how much lands on your skin each time you apply it.

More per application means more nights off before the next one. VT spells it out on each product page: the 100 "can be used everyday," the 300 "every 3 days," the 700 "every 7 days."

	Reedle Shot 100	Reedle Shot 300	Reedle Shot 700
Spicules per bottle	95,000	237,500	570,000
Bottle size	50 mL	50 mL	30 mL
VT's interval	Every night	Every 3 days	Every 7 days
Who it's for	First-timers, sensitive skin	Skin that tolerates the 100	Experienced users

So yes, a higher number means a heavier dose. But a heavier dose is not a better product. It is the same job done less often — which is why the 700 used like a nightly serum feels like punishment, not progress. The core of the formula is shared across all three, though the full ingredient lists do differ; the headline difference is the spicule count.

100 vs 300 vs 700: Which One Is Yours

Pick by how often you will realistically use it, not by how fast you want results. VT's own FAQ puts it plainly: most first-timers start at 100, the 300 is for those building tolerance, and the 700 is for experienced users.

Reedle Shot 100 — where you start

Reedle Shot 100 by VT Cosmetics — the entry point for how to use VT Reedle Shot every night

The 100 delivers the lightest dose of the three, and that is the point. It is meant to be used often and to build over weeks rather than to hit hard once. Even so, VT does not tell beginners to go nightly on day one — the brand's FAQ says to start at two to three evenings a week and work up. If your skin stays calm after a couple of weeks, the 100 can become an every-night step.

Reedle Shot 300 — for skin that has adapted

Reedle Shot 300 — VT's every-three-days spicule serum for skin that has adapted to the 100

The 300 carries two and a half times the spicules of the 100 in the same 50 mL bottle, so your skin gets two nights off between rounds. Each round does more work, so the rounds come less often — it is not a faster route to the same place. VT frames it as the step up once your skin tolerates the 100 comfortably — not the bottle to buy because you are impatient.

Reedle Shot 700 — the heaviest dose

Reedle Shot 700 — the once-a-week VT Reedle Shot with 570,000 spicules

The 700 packs 570,000 spicules into a smaller 30 mL bottle — the heaviest dose in the line. VT's page still lists it as an essence-serum texture, like the other two. Think of the week between uses as recovery built into the product, not a suggestion. This is the common mistake: the number looks like a ranking, so people buy the top one and use it like a nightly serum. Then it stings, the skin gets angry, and spicules get written off.

The line keeps growing. VT also sells a Mild 50 for daily morning and evening use, a row of single-active 100s — PDRN, Reti-A, collagen, and others — and, on its official store, a Reedle Shot 1300 billed as a night treatment for targeted areas. The logic holds across all of them: read the number as a dose, and space it accordingly. If you are curious about the PDRN version, we covered it alongside four other bottles in our guide to topical PDRN.

Why It Stings — and Why That's Not the Scorecard

Spicules are tiny needle-shaped structures. The idea comes from marine sponges, whose silica spicules have been studied as a way to open micro-channels in the outer layer of skin. In a 2017 lab study in Molecular Pharmaceutics, sponge spicules applied to pig skin increased the amount of a test molecule reaching into and across the dermis roughly 62-fold compared with untreated skin. That study used generic sponge spicules, not a Reedle Shot formula — but it explains the principle VT builds on: open the path, and what you apply next travels further.

That is also where the sting comes from. VT calls a mild, brief tingling normal and says it usually fades within a minute. What it is not is a progress meter. More sting does not mean more results, and a burn that lingers, or redness that is still there the next morning, is your skin telling you to stretch the interval or step down a number.

That is the reversal worth sitting with. If you judged your Reedle Shot by how much it hurt, you were grading the wrong thing. Judge it by the schedule.

How to Use VT Reedle Shot, Step by Step

How to use VT Reedle Shot — press it into clean, dry skin with your fingertips

The label calls Reedle Shot the first step of your routine, and VT's product pages say to apply it on the bare face after cleansing. VT's FAQ also allows it after toner. Either way, the rule that matters is dry skin and a gentle hand.

Cleanse, then dry completely. VT's pages ask for a bare face, straight after cleansing.
Use a small amount. VT's FAQ asks for a bead-sized amount matched to your number.
Press and pat — don't scrub. VT's FAQ is direct about it: pat gently until absorbed, do not rub. Keep it away from the eyes and lips.
Keep the next layers simple. A plain hydrating serum and moisturizer. Whatever you apply next travels further, so this is not the night for experiments.
Put retinol and strong acids on other nights. VT suggests alternating nights with strong actives like retinol.
Never mix numbers in one routine. VT's product pages say not to use the 100, 300, and 700 at the same time.
Wear sunscreen. VT pairs any morning use with SPF 30 or higher.
Skip broken skin. VT says to avoid wounded areas — and active breakouts you have picked at count.

Here is what a week looks like once your skin has adjusted:

	Mon	Tue	Wed	Thu	Fri	Sat	Sun
100	100	100	100	100	100	100	100
300	300	Retinol	Rest	300	Retinol	Rest	300
700	700	Rest	Rest	Retinol	Rest	Retinol	Rest

If you use retinol, take the 100 off those nights too. Reedle Shot fits neatly into a Korean evening routine — we mapped the full order in our Korean night skincare routine.

When At-Home Spicules Stop Being Enough

Reedle Shot is the at-home version of an idea clinics take much further. VT markets the line for rough texture, pores, and the marks acne leaves behind, and a bottle can keep that work going between appointments. What a serum cannot do is reach the depth a professional device can.

If old acne marks are the reason you bought a Reedle Shot in the first place, it is worth knowing what the clinic route looks like. We compared the options in our guide to Korean laser treatment for acne scars. And if texture is the goal, our walk-through of the glass skin facial in Seoul shows what 90 minutes in a Korean clinic chair actually involves. Results vary from person to person, at home and in the clinic.

The Glass Beauty Seoul Take

Reedle Shot only reached US shelves in a real way last year, when Ulta began carrying VT in July 2025. That is why so many people here are learning it backward — starting with the biggest number and quitting before the schedule has a chance to work.

In Korea, the logic is simple: pick your number by how often you will use it, not by how hard you want it to hit. Start at 100, two or three nights a week. Earn the 300 once your skin stops noticing the 100. Treat the 700 like a weekly appointment, not a serum.

That is how to use VT Reedle Shot without writing it off. Check the number on your bottle tonight — and put it on the calendar, not just the shelf.
