The Ordinary Retinol Serum 0.2% in Squalane is a powerful multi-purpose solution that reduces the appearance of pores, dark spots, fine lines, and improves skin texture. Enriched with a 0.2% concentration of retinol, it visibly plumps and firms the skin. Squalane protects against UV damage and helps minimize the risk of sun-induced age spots for a more even skin tone. This vegan serum should be used in the evening after water-based serums but before heavier treatments. It is important to note that sun protection is essential when using retinoids and it should not be used with other retinoid treatments.
