optic white overnight pen

Product descriptions identify hydrogen peroxide as the active whitening ingredient in the Optic White overnight gel pens.

Listings vary by product variant. Example listings show a 0.08 fl oz pen with 21 treatments, another 0.08 oz listing claiming 35 nightly treatments, and a mini/trial pen listed with 10 nightly treatments. Check the specific product page or label to confirm the exact size and treatment count.

Brush and dry your teeth, then use the pen’s precision applicator to apply the quick-drying gel to each tooth before bed. Leave the gel on overnight and brush your teeth when you wake up.

Most reviewers find the pens simple to use when following directions, but some warn the gel or brush can clump, harden, or leave residue if teeth or the applicator are wet. Product details note a quick-drying serum and precision applicator intended to reduce residue.

Product descriptions advertise visible whitening in about one week. Many reviewers report seeing improvement within several nights to about a week, with continued improvement when used as directed.

Yes. They are offered in trial/mini travel sizes and are described as compact and easy to pack for on-the-go use; mini pens provide a limited number of nightly treatments.
