Multi-Size
Spicule
An equal blend of 100·200·270·320 µm — four sizes — next-generation Spicule.
A single product delivering simultaneous multi-layer care from the Stratum Corneum to the lower epidermis.
One Spicule,
Entire Epidermis Simultaneous Care
Leveraging the unique characteristic that each Spicule size acts at a different skin depth, an equal blend of four sizescreates a distinctive multi-layer-acting Spicule.
Conventional Single Size
Using only one size acts on a specific skin layer only. You must choose between surface care or deep care.
Multi-Size Blend
An equal blend of four sizes acts on the Stratum Corneum → Upper Epidermis → Middle Epidermis → Basal Layer simultaneously. Multifunctional care in a single product.
4-Size Equal Blend (25% each)
Optimally balanced to maximize the characteristics of each size
- Minimal-stimulus design
- Daily-use friendly
- Surface care
- Most versatile
- Balanced efficacy
- Mass-market products
- Strong stimulation
- Intensive care
- Aesthetic-clinic exclusive
- Maximum stimulation
- Thick skin layers
- Scalp-dedicated
How the 4 Sizes Act on Skin
Each size acts at a different depth, simultaneously caring for the entire epidermis
What Makes Multi-Size Spicule Different
Simultaneous Multi-Layer Care
Acts simultaneously on four layers — from the Stratum Corneum to the Basal Layer. Deep care without surface irritation, all at once.
Graded Stimulation Spectrum
A continuous spectrum from mild stimulation (100 µm) to strong stimulation (320 µm). Smaller sizes handle sensitive areas; larger sizes address thicker skin zones.
All-in-One Functionality
Hydration (100 µm) + Versatile care (200 µm) + Intensive penetration (270 µm) + Deep action (320 µm) integrated into a single product.
