Principia is a Brazilian dermocosmetics brand founded in 2020 in São Paulo with a clear mission: democratize high-performance skincare through science-backed formulas, radical ingredient transparency, and fair, accessible positioning. Instead of relying on hype, Principia focuses on active ingredients at disclosed percentages, straightforward formulations, and a minimalist, clinical aesthetic designed for everyday use.
This collection features the brand's most iconic treatment essentials — especially its targeted serums built around globally trusted actives. Highlights include Vitamin C + Ferulic Acid serums for visible brightness and uneven tone, and Niacinamide + Zinc PCA formulas for oily skin concerns like excess shine, enlarged pores, and blemish-prone texture. For smoother-looking skin, Principia is also known for its exfoliating line featuring AHA-based options such as Glycolic Acid, plus multi-active blends for advanced routines, balanced by hyaluronic-acid-focused hydration.
Many formulas are designed with a sensitive-skin-aware approach, commonly avoiding added fragrance (product-dependent). The brand states it does not test on animals, reinforcing its commitment to responsible development.
