NEW Yon-Ka Serum Omega soothes skin + seals in hydration
Are you prepared to protect your skin as it’s bombarded by Boston’s harsh winter months?
The latest from the Yon-Ka Paris Intensive line, Serum Omega, acts as the final flourish to your routine. Serum Omega is the final step before applying SPF and makeup.
The Omega-rich formula creates a barrier that seals in hydration and nourishing ingredients from your serums and moisturizers.
This oil-in-serum helps repair and soothe existing damage to inflamed skin and reduces redness and transdermal water loss to combat even the most blustery days Boston throws at us.
Ask your esthetician for more information on how Serum Omega can perfectly punctuate your skincare routine during your next visit.
