1. Alginate Pack Chemistry: 4 Core Ingredients🔗

Calcium Ion Exchange Reaction Hardening System🔗
Lindsey modeling packs utilize an alginate (seaweed-derived polysaccharide) based hardening system. When powder and water are mixed, a chemical reaction occurs that transforms the mixture into a rubber-like elastic pack within 20 minutes.
| Ingredient (Korean) | English Name | EWG | Function |
|---|---|---|---|
| 규조토 | Diatomaceous Earth | Grade 1-2 | Abrasive, absorbent, bulking agent (pack volume and absorption) |
| 칼슘설페이트 | Calcium Sulfate | Grade 1 | Calcium ion (Ca²⁺) supply, initiates hardening reaction |
| 알진 | Algin | Grade 1-3 | Binder, thickener, gel formation |
| 포타슘알지네이트 | Potassium Alginate | Grade 1 | Emulsion stabilizer, cross-linking with calcium ions |
Hardening Mechanism:
- Algin/Potassium Alginate swells when mixed with water, forming gel
- Calcium Sulfate releases calcium ions (Ca²⁺)
- Calcium ions form cross-linking between alginate molecules
- 3D network structure completes → Hardens within 20 minutes
Lindsey's major modeling pack products (7-Type Selection, Charcoal, Premium series) all use these 4 ingredients as a common base. To control hardening speed, 3 pH adjusters (Tetrasodium Pyrophosphate, Magnesium Oxide, Cellulose Gum) are additionally formulated, and Glucose (EWG Grade 1) is used as a humectant in 69% of products. Most core ingredients are EWG Grade 1-2.
2. 7-Product Lineup Differentiation Strategy🔗

Common Base + Specialized Ingredients (5-8 types)🔗
Lindsey configures 7 product lines by adding 5-8 specialized ingredients on top of the 8-ingredient alginate base system.
| Product Name | Core Specialized Ingredients | Total Ingredients | Primary Effect |
|---|---|---|---|
| Charcoal Modeling Pack | Charcoal Powder, Volcanic Ash, Kaolin, Bentonite | 24 types | 4-Clay Complex Adsorption |
| Soothing Herb Modeling Pack | Mugwort, 3 Green Tea Types, Centella, Portulaca, Licorice, etc. (15 herbs) | 29 types | Herbal Complex Soothing |
| Modeling Pack 7-Type Selection (Collagen/Tea Tree/Lavender/Charcoal/Herb, etc.) | Collagen, Adenosine, Niacinamide, etc. | 29 types | Choose from 7 Types |
| Tea Tree Modeling Pack | Tea Tree Leaf Powder, Peppermint Oil | - | Pore Care + Cooling |
The Charcoal Modeling Pack features 4 types of clay (Charcoal Powder, Volcanic Ash, Kaolin, Bentonite) that multi-layer absorb sebum and impurities. The Soothing Herb Modeling Pack delivers soothing effects with 15 herbs including Mugwort, 3 Green Tea types, Centella, Portulaca, and Licorice. An efficient strategy with the same base, only replacing specialized ingredients.
3. The Secret Behind ₩2,500 Value-for-Money🔗

Average 27 Ingredients: Core-Focused Design🔗
Lindsey modeling packs average 27 ingredients. Sheet masks require more ingredients in essence form, but modeling packs have a different product format.
Sheet Mask vs Modeling Pack Structure Comparison:
- Sheet Mask: Purified water + essence base → Requires large amounts of humectants, emulsifiers, thickeners
- Modeling Pack: Powder form → Alginate system (8 types) + functional ingredients (5-8 types) + fragrance/preservatives
Since modeling packs require users to add water directly, they eliminate the need for solvents, emulsifiers, and thickeners required in essence formulations. Instead, they concentrate only the alginate hardening system and functional ingredients to achieve cost efficiency. Even at a ₩2,500 price point, they include functional ingredients like adenosine (wrinkle improvement), niacinamide, and collagen.
Frequently Asked Questions🔗
Q. What's the difference between modeling packs and sheet masks?A. Modeling packs are facial packs where you mix powder and water for use. As alginate hardens, it adheres tightly to skin to penetrate active ingredients, and removes dead skin cells and impurities when peeled off. Sheet masks are non-woven fabric impregnated with essence for immediate use, but have weaker adhesion.
Q. How can wrinkle-improvement ingredients be included at ₩2,500?A. Since modeling packs are in powder form, they don't need purified water, solvents, or emulsifiers. The efficient formulation consists only of alginate system (8 types) and functional ingredients (5-10 types) concentrated. Functional ingredients like adenosine can be effective in small amounts, making them applicable to value-for-money products.
