The Institut Esthederm Intensive Retinol Oil Serum is a high-performance night treatment that redefines skin texture, radiance, and firmness through advanced retinol science. Formulated with a concentrated dose of pure retinol in a nourishing dry oil base, it delivers powerful cellular renewal while preserving the skin’s comfort and barrier integrity. Retinol stimulates collagen synthesis, smooths fine lines, and refines pores, while the lipid-rich formula cushions and protects even the most delicate complexions from dryness and irritation. Over time, skin appears visibly regenerated, smoother, more even, and glowing with youthful resilience.
