• Lightweight & Fluid: The name "Wow So Light" is reflected in the formula. Primary solvents like Water and Butylene Glycol (or 1,3-Propanediol in 03) keep the texture fluid for easy application. Glycerin provides a smooth glide.
• Soft, Comfortable Dry-Down: Key ingredients like Acrylates/Ethylhexyl Acrylate Copolymer and Styrene/Acrylates Copolymer form a thin, flexible film that dries down without feeling heavy, tight, or sticky on the lid.
• Non-Caking: The use of Silica and Kaolin (in 01 & 03) helps control oil absorption and provides a smooth, even application without clumping or caking in fine lines.

• Long-Wearing & Smudge-Resistant: This is the primary function. Multiple film-forming polymers (Styrene/Acrylates Copolymer, Acrylates/Ethylhexyl Acrylate Copolymer, Ammonium Styrene/Acrylates Copolymer) create a durable, elastic network that binds the pigment to the skin, resisting transfer and smudging once set.
• Water-Resistant: The polymer film is resistant to water and sweat. Ingredients like Sodium Laureth-12 Sulfate (a surfactant) are used here to help the formula emulsify during manufacturing and application, but not enough to compromise the film's water resistance once dry.
• Flexible & Crack-Proof: The specific blend of acrylic copolymers is chosen for flexibility, allowing the liner to move with the skin without flaking or cracking throughout the day.
• Precise Application: The fluid texture and likely brush applicator (standard for such formulas) allow for sharp, precise lines, from thin strokes to dramatic wings.

• For Oily Eyelids: Kaolin (a clay) in shades 01 & 03 helps absorb excess sebum, preventing the liner from breaking down prematurely. Silica also aids in oil control.
• Sensitive Eye Area Consideration: It uses milder, broad-spectrum preservative systems like Phenoxyethanol paired with Ethylhexylglycerin and Sodium Dehydroacetate. Potassium Sorbate and Sodium Benzoate are also gentle preservatives. The formula is fragrance-free (no obvious fragrant oils or parfum listed).
• Gentle Removal: Despite being water-resistant, the presence of emulsifiers like Ceteareth-25, Laureth-21, and Lauryl PEG-8 Dimethicone means the film can be broken down more easily with a dedicated makeup remover or oil-based cleanser compared to fully waterproof formulas, making removal less abrasive.
• Maintains Hygiene: The inclusion of Caprylyl Glycol acts as both a moisturizing agent and a preservative booster, helping to keep the product fresh.
