Science & Research
Better skincare starts with better science.
Sensitive, reactive, blemish-prone, and rosacea-prone skin can involve overlapping biological processes, including oxidative stress, impaired barrier function, altered microbial communities, and inflammatory signalling.
At Authentic Ego, we study these interconnected mechanisms to develop formulations that address more than surface symptoms.
Our approach combines published scientific research, the pharmacokinetics and pharmacodynamics of ingredients, and deliberate ingredient selection to create skincare designed to target the upstream drivers that lead to visible skin concerns.
Research-led. Purposefully formulated.
Our approach integrates published scientific research, cosmetic chemistry, and real-world product experience to develop formulations for sensitive, reactive, and blemish-prone skin.
01 — Mechanisms first
We examine oxidative stress, barrier dysfunction, microbial imbalance, and inflammatory signalling to inform formulation development.
02 — Evidence-based ingredient selection
We evaluate ingredients by their supporting research, effective concentrations, tolerability, and compatibility within the finished formula.
03 — Compatibility by design
We consider allergen potential, irritant load, oxidative stability, microbiome impact, and follicular compatibility.
04 — Real-world insights
Customer experiences help inform product development and refinement without replacing controlled scientific evidence.
05 — Continuous refinement
We revisit formulation decisions as new research emerges, distinguishing established findings from preliminary evidence.
