Yes! Our typical suggested skin care regimen is cleanse, tone, treat, moisturize, SPF. Within each category, if there is more than one product, we recommend going from thinnest to thickest consistency, or least occlusive to most occlusive. In this case, use the Omega Drops after the Vitamin C + HA3 Daily Serum or Correcting/Defying Serum, and before your moisturizer.
