Does the VT Reedle Shot, the First Daiso Open-Run Skincare, Really Work?

The reason why VT Reedle Shot has rapidly grown in popularity in Korea is due to its effective skin improvement mechanism utilizing spicules (Spicule, marine micro-needles). With the support of Daiso’s budget-friendly marketing strategy and easy accessibility, it has consistently been a popular choice among consumers.

Reedle Shot products containing spicules are particularly known for their effectiveness in pore refinement. But can they replace beauty devices like MTS rollers, which are also known to be effective for pore care? In this article, we will provide a detailed comparison of both methods and suggest the best approach to achieve optimal results.

VT Reedle Shot (Spicule) and Its Skin Improvement Effects

Spicules are natural micro-needles extracted from marine sponges. When applied to the skin, these microscopic needles penetrate deep into the skin.

✔️ How It Works

• Physical Penetration Effect: Spicules create micro-stimulation on the skin and remain embedded for 24–48 hours, continuously working within the skin.
• Exfoliation Induction: The skin perceives spicules as foreign substances, prompting the shedding of the outer skin layer and accelerating new cell formation.
• Cell Regeneration Boost: The penetration of micro-needles activates collagen production, promoting skin regeneration.

Spicules mainly function by exfoliating the skin and stimulating renewal. Their advantages include quick results, such as dead skin cell removal and an immediate brightening effect. However, while they offer temporary skin improvement, their long-term effects are limited. Prolonged use, especially on sensitive skin, may weaken the skin barrier, causing irritation, dryness, redness, and stinging. Additionally, since spicules themselves do not contain active ingredients, their ability to deliver nutrients directly into the skin is limited.

What Is an MTS Roller? Mechanism and Effects

MTS (Micro-needling Therapy System) rollers are skincare devices designed to create micro-channels on the skin’s surface using fine needles. These tiny punctures allow active ingredients to penetrate deeper into the skin. Typically available in roller or pen types, MTS rollers stimulate the skin’s natural healing process, boosting collagen and elastin production.

Key Benefits of MTS Rollers

✔️ How It Works

• Stimulates Skin Regeneration – The creation of micro-channels triggers the skin’s natural healing process, promoting collagen and elastin synthesis.
• Enhances Absorption of Active Ingredients – By temporarily opening the skin barrier, MTS allows skincare ingredients to penetrate deeper for maximum effectiveness.
• Reduces Fine Lines – Boosts skin elasticity and helps minimize the appearance of wrinkles.
• Minimizes Pores and Improves Skin Texture – Helps refine the skin’s surface, tightening pores and creating a smoother complexion.
• Lightens Pigmentation – Inhibits melanin production and helps fade existing dark spots.

To fully maximize the benefits of MTS rollers, it is essential to use them in combination with high-quality ampoules containing active ingredients.

Differences Between Spicule-Based Skincare and MTS Roller Treatments

As at-home skincare solutions that can serve as alternatives to professional dermatological treatments gain popularity, two standout methods—VT Reedle Shot (spicule-based skincare) and MTS rollers (micro-needle-based devices)—have been widely adopted. However, there are significant differences in their mechanisms and the longevity of their effects.

Problematic Skin: Acne, Inflammation, Pores, Skin Texture, Skin Tone, Dehydration, Fine Lines

There are often questions about how deep the fine needles of an MTS roller can penetrate into the skin and whether it can actually provide long-term skin improvement effects. Additionally, since spicules remain in the skin for 24–48 hours, inducing continuous stimulation, many wonder if the ampoule penetration through the MTS roller is not as deep.

In this article, we will explain the penetration depth of micro-needles and the skin regeneration process based on scientific studies and physiological principles, and compare it with spicules.
