【Danger⚠️】Silky-smooth skin in just one day?

The viral Korean cosmetic “Reedle Shot,”

and why skin problems are increasing due to incorrect use

This is “Yeppuriko,”

your one-stop guide to enjoying Korean beauty, travel, and food with peace of mind.

The Korean cosmetic containing microneedles that are far thinner than pores,

Reedle Shot.

Thanks to its accessibility—it can even be found at DAISO—and

reviews saying, “My skin became silky smooth in just one day,”

its popularity quickly spread, mainly through social media.

However,

skin problems caused by incorrect use are also on the rise.

This time, based on the opinions of Korean dermatologists,

we will explain the mechanism, precautions, and proper use of Reedle Shot

in an easy-to-understand way.

🔬 What is Riddle Shot?

How Microneedle Technology Works

Riddle Shot is

a skincare item that applies microneedle technology.

Needle-shaped microscopic particles enter the stratum corneum,

providing stimulation so subtle that it is invisible to the eye.

As a result,

• Temporary “pathways” are created on the skin’s surface
• Beauty ingredients can penetrate more easily
• Skin turnover is promoted during the recovery process

That is how it works.

The key point is

“deliberately providing microscopic stimulation.”

This very characteristic is also why using it correctly is essential.

📊 Do you understand the differences between the numbers?

What 100 / 300 / 700 / 1000 Mean

The numbers on Reedle Shot

indicate the approximate amount of needles.

Reedle Shot 100

・Lower amount of needles

・Mild stimulation

・Suitable for sensitive skin

・Recommended for beginners

Reedle Shot 300

・A good balance between effectiveness and stimulation ◎

・Suitable for normal skin

Reedle Shot 700

・Stronger stimulation

・For those who know they have resilient skin

Reedle Shot 1000

・Very strong stimulation

・For advanced users accustomed to skin needle products

Do NOT choose a high number from the start!

Always start with 100–300,

and it is important to check your skin’s reaction.

💡 Is “smooth skin” after just one use really possible?

Korean dermatologists’ views

“My skin changed the moment I used it!”

Many people report experiences like this.

However, according to dermatologists──

• Short-term smoothness: ◯
• Temporary glow: ◯
• Long-term improvement in skin quality: △
• 
  

In many cases, the skin’s surface has been temporarily smoothed,

and consistent use and proper care are necessary for fundamental skin improvement.

⚠️ Skin conditions in which use should be avoided

Avoid using it if any of the following apply to you.

• You have atopic dermatitis
• Extremely sensitive skin
• Frequent inflammation or acne
• Severe skin irritation
• You have been diagnosed with a thin stratum corneum

If used forcefully,

• Severe stinging
• Prolonged redness
• Worsening inflammation
• Reduced barrier function

may occur.

✨ How to Use Correctly [Important]

STEP 1: Cleanse Your Face

Prepare clean, bare skin.

STEP 2: Take an Appropriate Amount

The recommended amount is approximately 0.5 ml.

Using more does not necessarily increase the effectiveness.

STEP 3: Apply Gently

・Do not rub

・Stop using if the stinging is severe

・Do not massage

STEP 4: Moisturize Thoroughly

・Serum + cream

・Seal in moisture with oil

Recommended Frequency of Use

・Up to 2–3 times per week

・Do not use daily

🎯 How to Use on Different Areas

• Around the eyes, cheeks, and forehead → 100
• Around the nose and areas with thickened dead skin → Consider 300 or more

💧 Aftercare After Use

• Be especially mindful of moisturizing, at about twice your usual level
• Sunscreen is essential
• Discontinue retinol and peeling products
• Avoid highly irritating cosmetics

If redness appears,

soothe the skin with a chilled sheet mask or similar product.

Essential Care

✓ Moisturize more than usual (be mindful of about twice your normal level)

✓ Always use sunscreen

✓ Take a break from cosmetics with high alcohol content or strong irritants

✓ Do not use together with peeling-type cosmetics

✓ Temporarily stop using retinol as well

Cooling Care

If you feel redness or heat

→ Soothe the skin with a chilled sheet mask or similar product.

In particular, never forget to protect your skin from UV rays!

Skin injured by needles is more susceptible to UV damage, which may also cause dark spots.

🔍 What Happens to the Needles That Enter the Skin? Common Questions Answered

“Won’t the needles that enter my skin remain there?”

This is a concern we hear often.

→ Basically, there is no need to worry.

They are designed to gradually shed along with the stratum corneum.

They do not accumulate inside the body.

However, if you experience strong discomfort or anything unusual after use, stop using it immediately and consult a dermatologist.

⏰ When to Expect Results｜Consistency Is Important, but Overuse Can Backfire

Here is a general guideline for when you can expect to feel the effects of Riddle Shot.

Immediate effects

・Exfoliation → A change in skin texture from the same day

・Smoothness → Easy to notice within a few days

Changes with continued use

・Overall changes in skin quality → 4–6 weeks

・Changes around the pores → 8–12 weeks

Rather than expecting “dramatic changes right away,” it’s best to continue with the mindset that your skin will gradually change. ◎

If you rush and overuse it, it may instead cause skin problems.

🚨 Signs to Stop Using It Immediately

• Redness lasting more than 24 hours
• Increasing pain or stinging
• Swelling that does not subside
• Severe itching
• A sudden increase in breakouts

If you notice anything unusual,

stop using it immediately and consult a dermatologist.

💰 Differences Between the Authentic Product vs DAISO Version

Authentic Product (VT)

Volume: Approximately 30ml

Stable ingredient formulation

DAISO Version

• 2ml × 6 tubes
• Easy to try, but the ingredient composition differs

If it’s your first time, a patch test is essential.

🇰🇷 How It’s Used in Korea｜It’s Not Used Just Because It’s Trending

In Korea, before using Reedle Shot,

・Checking your skin condition

・Choosing the strength (100/300/700/1000)

are generally considered together as a set.

Rather than using it because “everyone else is,” there is a well-established culture of prioritizing “whether it suits my skin.”

It’s important to face your own skin instead of being swept along by trends.
