Key Differences: Arginine vs Dimethicone

Arginine
Arginine functions primarily as a humectant. Its main purpose is improving skin hydration levels and moisture balance, which contributes to supporting smoother and plumper skin appearance. Commonly formulated into water-based serums, toners, moisturizers, and hydrating masks.
Dimethicone
Dimethicone functions primarily as a emollient. Its main purpose is reducing dryness, flakiness, and rough texture, which contributes to enhancing skin barrier comfort and tactile smoothness. Commonly formulated into creams, balms, ointments, and rich moisturizers.
When to Choose Arginine or Dimethicone
Choose Arginine for improving skin hydration levels and moisture balance. Effective in facial moisturizers, hydrating serums, body lotions, and sheet masks.
