Great product, frustrating pump mechanism requiring YouTube troubleshooting for proper use.

Effective serum hampered by defective pump design; customers recommend watching YouTube tutorials for troubleshooting steps to activate dispenser.

This review is from Amazon.com for product:

Medix 5.5 Vitamin C Cream Brightening Body Lotion & Face Moisturizer | Anti Aging Vitamin C Lotion For Women & Men Helps Soften The Look Of Dark Spots, Wrinkles, & Uneven Looking Skin Tone, 2-Pack

Product itself is very good. Could not get the pump to "pop up" and operate. Had to unscrew the pump unit from the bottle, dry off the wide inner tube with a few paper towels, then tightly grip the white inner tube with a fresh paper towel while rotating the top pump dispensing nozzle counter clock wise; and it took quite a bit of force to "un-stick" the pump and get it to pop up. For a good visual regarding this fix ,check out the videos on You Tube.

Vitamin Basics & Tips

Vitamin C, a potent antioxidant, plays a vital role in skin health by neutralizing free radicals caused by UV exposure and pollution. Its ability to stimulate collagen synthesis helps reduce wrinkles and improve skin texture, making it a staple in anti-aging skincare routines.

When using vitamin C serums, proper storage is crucial – exposure to light or air can oxidize the ingredient, turning it yellowish and less effective. Many dermatologists recommend combining topical vitamin C with sunscreen, as it enhances UV protection and minimizes sun damage.

Oral vitamin C supplements (typically 65-90mg daily) support immune function and iron absorption. However, topical application provides direct skin benefits without digestive system limitations. Those with sensitive skin should opt for stabilized forms like sodium ascorbyl phosphate to avoid irritation from pure ascorbic acid.

Filler-free Vitamin C supplement ensures pure nutrient intake without unnecessary additives.
