@makemoneywithduchess: While Retinol thins out the outer layer to force a reset, EGF actively thickens and reinforces a compromised skin barrier without any shedding. Try this Blue EGF Serum if you’re struggling with Retinol products but still want skin renewal support! @dear, Klairs #klairsegfserum #skintok #kbeauty #retinol #egf
