Cos De BAHA Retinol 2.5% Serum

Cos De BAHA Retinol 2.5% Serum 30ml is a retinol serum with 2.5% retinol, as the name says. Retinol is one of the best-known ingredients in age-care skincare, used for smoother, more refreshed-looking skin.

It's suited to adults who have some experience with retinol, or who want to introduce it slowly.

• Use only at night on clean, dry skin.
• Apply a few drops, avoiding the eyes and lips.
• Follow with a moisturiser.

Start two nights a week and build up. Dryness or flaking can happen at first. Always use sunscreen during the day. Don't use with strong acids on the same night. Avoid during pregnancy unless your doctor approves.
