Enlarged Pores: What You Can Actually Do About Them (and What You Can't)
Dr. Anaïs BambiliPores are one of the most common skin concerns—and one of the most misunderstood. Every week, I see patients who are frustrated by “pore-minimizing” products that don’t live up to their promises. The reason is simple: most of these products don’t understand what an enlarged pore really is.
The truth about pores: they don't open or close
This is the number one myth in skincare. Pores don't have muscles. They can't open up in the heat and close in the cold—it's biologically impossible.
What's really going on: The apparent size is influenced by the amount of sebum and keratin inside them, the elasticity of the surrounding skin, and the skin's hydration level.
What Really Makes Pores Look Larger
Excess sebum is the main factor. The buildup of keratin around the pores makes them more visible. The loss of elasticity that comes with age (decrease in collagen) causes the skin to “sag” around the follicles. Sun damage accelerates all of these processes.
Ingredients That Truly Reduce the Appearance of Pores
5% niacinamide is the most well-documented active ingredient: it regulates sebum production and improves peri-follicular elasticity.
An example of clinical study results: a 96% reduction in blackheads in the T-zone with VIBRE Paris Serum.

Regular gentle exfoliation (PHA gluconolactone) removes keratin buildup. Peptides stimulate collagen production and restore elasticity around the pores.
What We Can't Change
The genetic size of your follicles is fixed. What we can change is their appearance by reducing the factors that accentuate them (sebum, keratin, loss of elasticity). Visible and measurable results—that’s what our clinical trials document.
