Meimei puts NAD+ and collagen extract into one light serum you massage into your face and neck, morning and night.

Fine lines, a softer jawline and skin that looks dry and flat by lunchtime tend to show up together, and most wrinkle creams only go after one of them. Meimei's serum is built around NAD+ and collagen extract, with glycerin for moisture, in a texture light enough to wear under sunscreen. One bottle covers firmness, lines, hydration and glow.

A lot of firming creams print a big promise on the lid. Read the back and you still can't tell which ingredient is meant to do the firming.

Fine lines, a softer jawline and dull, thirsty skin usually turn up together, so buying a separate fix for each one gets expensive fast. I had a cream for lines, another for dryness and a mask for glow, and my face looked exactly the same.

Meimei puts NAD+ and collagen extract into one lightweight serum, with glycerin to hold in moisture. A pearl-sized amount goes after the look of firmness, fine lines, dryness and dullness at once, and that is how half my shelf ended up in a drawer.

Rich creams sit on top of my skin, turn shiny by noon and slide around under makeup. I stopped wearing half of mine in the daytime for that reason.

Meimei is a light serum. You massage it into clean skin until it is fully absorbed, and your face feels soft with nothing tacky left on top. Glycerin pulls water into the skin while NAD+ and collagen extract work on how firm and smooth it looks. People in the brand's consumer study reported 36.8% better hydration after the very first application.*

Before I put anything new on my face, I look for numbers. Meimei ran a consumer self-assessment study on this serum and put the results on its product page.

After 2 weeks, users reported a 29.4% visible reduction in fine lines and wrinkles, 33.1% better elasticity and firmness, 27.6% smoother texture and 24.9% more radiance. These are people rating their own skin, so treat them as a guide. They lined up with what I saw in my own bathroom mirror.*

Many users notice softer, better hydrated skin in week one, with firmness, lines and glow improving over 2 to 4 weeks.*

Collagen is the protein that keeps skin firm and full, and the body makes less of it as the years go by. NAD+ is a molecule your cells rely on for energy, and it has become one of the most talked-about names in anti-aging skincare.

The ingredient list is short enough to read in one breath: Aqua, Glycerin, 1,2-Hexanediol, Carbomer, Arginine, Nicotinamide Adenine Dinucleotide and Collagen Extract. I like knowing exactly what I'm putting on my face twice a day, and here I can check every line.

Cleanse, tone, then massage a pearl-sized amount over your face and neck until fully absorbed. I do it every morning and again before bed. It layers with other serums and sits happily under sunscreen or a richer night cream, so you keep the products you already like.

In the first week my skin felt softer and better hydrated. By week three a friend at dinner leaned in and asked, quietly, if I'd had filler. I hadn't. The glow is what people notice first, and it's the part I'd miss most if I stopped.*

The look holds through the day, too. By mid-afternoon my skin still looks plump and smooth, and that used to be exactly when my makeup started settling into every line.*
