Frequently Asked Questions

What makes Serum 16 different from a standard retinol serum?

Serum 16 uses CosMedix's proprietary LG-Retinex Microencapsulation technology, which encapsulates both Retinol and Retinal within microscopic capsules that release the actives in a controlled, time-released manner. This significantly reduces the irritation, redness, and peeling associated with traditional Retinol while still delivering a 16% concentration. The formula also contains Squalane, Sodium Hyaluronate, and Phospholipids to actively boost hydration alongside the Retinol benefits.
Is Serum 16 suitable for complete retinol beginners?

Serum 16 is positioned by CosMedix as a gentle retinol option for dry and sensitive skin types that cannot tolerate traditional Retinol. However, we typically recommend that complete beginners start with Define 2% AGP Retinol Complex first to build initial tolerance. Once comfortable with Define, Serum 16 offers an excellent hydrating retinol alternative for dry and sensitive skin.
Can I use Serum 16 every night?

Starting with every 1 to 3 nights and gradually working up to nightly use as your skin builds tolerance. It is a PM-only product and should not be applied in the morning, as it may cause sun sensitivity. Always wear sunscreen daily.
