Description
Spa Treatment Insert Gel A — Stem Cell & Spicule Base Gel
Spa Treatment Insert Gel A is a professional-grade base gel from one of Japan's leading aesthetic skincare brands. It is designed to be applied as a first step — "inserted" into the skin — to prepare and amplify the absorption of the serums and creams that follow. The formula combines two powerful technologies: microspicules (microscopic marine sponge fibres that create micro-channels in the skin's surface for enhanced ingredient delivery) and HAS (Highly Active Stem) components derived from selected, cultivated plant stem cells.
After application, skin becomes visibly firmer, lifted, and more elastic. The gel texture is light yet active — you can expect a brief tingling sensation from the spicules, which is a sign of ingredient penetration.

How to Use
- Cleanse skin thoroughly and pat dry.
- Apply Insert Gel A as the first step in your skincare routine — before toner, serum, or moisturiser.
- Take a pea-sized amount and gently press it into the skin using circular massaging motions for 30–60 seconds until absorbed.
- A mild tingling or warming sensation is normal and indicates microspicule activity.
- Follow immediately with your regular toner, serum, and moisturiser for amplified absorption.
Frequency: Evening use recommended. Start with 2–3 times per week; increase to daily as skin acclimates.
Important: Microspicule gels can cause temporary redness or sensitivity. Avoid sun exposure immediately after application. Always follow with SPF in the morning.

FAQ
What are microspicules and are they safe?
Microspicules are microscopic silicon dioxide fibres derived from freshwater marine sponges. When massaged into skin, they create tiny micro-channels that temporarily enhance the penetration of active ingredients. They are safe for home use; some tingling and brief redness is normal. Avoid using this product before sun exposure — always follow with SPF.
What does 'insert' mean in the product name?
'Insert' refers to the intended use: you apply this gel first to 'insert' active ingredients more deeply into the skin's surface before your regular toner or serum. Think of it as a delivery booster — a base layer that prepares skin to receive and absorb what comes after.
Is this suitable for sensitive skin?
Microspicule gels are generally not recommended as a first product for very sensitive, reactive, or rosacea-prone skin due to the physical micro-exfoliation effect. If you have sensitive skin, please do a patch test first and start with 1–2 applications per week.
Is this the genuine Japanese product?
Yes — Tsujimoto Market stocks authentic Spa Treatment products sourced from Japanese suppliers and ships directly from our warehouse in Kobe, Japan.
How long does shipping take?
Orders dispatch within 2–6 business days. Delivery is typically 7–20 days depending on your country. A tracking number is provided after dispatch.
