If you have searched for these products in English, you have probably seen them called Riddleshot. That spelling comes from translation of the Korean 리들샷, and it has propagated across resellers, marketplace listings and social posts to the point where it looks almost official.
It is not. VT Cosmetics' own English name is Reedle Shot - a compression of reed and needle, describing what the products actually contain. Worth knowing if only because searching the correct spelling will bring you rather better sources than searching the wrong one.
What a "reedle" actually is
The line's defining feature is not a chemical active but a physical one: microscopic spicules suspended in the formula. On the ingredient lists across the range - including Mild Reedle Shot 50, Reedle Shot 1000, the PDRN Reedle Shot Eye Lifter and the PDRN Reedle Shot Cream - these appear as silica.
The principle is straightforward. The spicules are rigid, needle-shaped and small enough to create transient micro-channels in the uppermost layer of the skin as the product is pressed in. The intention is to help the rest of the formula reach further than it otherwise would, and to encourage cell turnover through mild controlled irritation.
That mechanism explains two things at once: why the range is banded by strength rather than sold as a single product, and why it tingles. Both follow from spicule concentration rather than from any active ingredient.
The five strengths
VT Cosmetics has developed six strengths. The number refers to spicule content, and it is the only variable that matters when deciding how often to use one. We have listed the five most commonly used strengths - Reedle Shot 1300 is not included here, as it is recommended generally for spot treatment and not advised to be used regularly.
VT's own labelling for these tiers reads as #All day mild care, #Daily natural care, #3-day cycle intensive care, #7-day cycle special care and #7-day cycle strong care. Rendered into plain English, they describe maximum sensible frequency - not a prescription to use all five.
VT's published schedule
How to read it — and how not to
The pattern is more deliberate than it first appears. The gentlest strength carries every morning and the quietest evening. The two heaviest treatments - 1000 on Thursday and 700 on Sunday - sit three days apart, each with a lighter night either side. The 300 appears twice, three days apart, and the 100 fills the gaps.
The frequency tags describe each product's ceiling, not its slot. #3-day cycle on Reedle Shot 300 means that strength should not be used more often than every third day. It does not mean you must use it on a three-day rhythm, and it certainly does not mean the calendar is a routine you should adopt wholesale.
The calendar is one worked example, not a regimen. Reproducing it exactly requires owning four of the five strengths. That is a legitimate demonstration of how the tiers interlock, but it is also, unavoidably, a demonstration of why you might buy several. Read it as an illustration of pacing - heavy treatments spaced apart, gentle ones in between - rather than as instructions.
Anyone using a single bottle can extract the useful principle in one line: match the strength to the frequency, and do not stack two strong nights together.
The tingling
VT's own note is candid: Reedle Shot products produce a tingling sensation on application, and its intensity varies with the strength used.
This is expected rather than a fault. It is the spicules doing what they are there to do. It should be brief and it should not escalate - a sting that builds, or lingering heat and redness, means the strength is too high for your skin or the product is being used too often.
Where to start
VT recommends first-time users begin with Mild Reedle Shot 50 or Reedle Shot 100, the two lowest intensities. That is sound, and we would go slightly further: start at 50, use it at night only for the first fortnight, and see how your skin responds before adding anything stronger.
Anyone with an actively compromised barrier, rosacea, or who is using prescription retinoids or acids should treat this range with real caution. A product designed to create micro-channels is not a good pairing with skin that is already struggling to keep things out.
A note on the PDRN variants
Several products in the range carry PDRN branding - the Eye Lifter and the Cream among them. PDRN appears on their ingredient lists as sodium DNA, and both declare the concentration outright: 3.45ppm in the PDRN Reedle Shot Eye Lifter, and 0.05ppm in the PDRN Reedle Shot Cream.
Parts per million is a very small quantity, and the near seventy-fold difference between two products sharing the same PDRN branding is worth noticing. We have written separately about the gap between PDRN's clinical pedigree and its cosmetic concentrations; this range illustrates the point neatly. Whatever these products do well, it is reasonable to assume the spicules are doing more of the work than the PDRN.
What we are doing next
We have been using the Reedle Shot line for over two years now. Individual reviews of each strength will follow, with our own ratings, wear notes and repurchase verdicts.
