Medik8 Liquid Peptides Advanced MP - Peptide Serum - Face Serum for Wrinkle Reduction - Hydrating and Supports Collagen, Hyaluronic Acid - 1 oz.

I’m 52, post-menopausal, with mature, dry skin, and I’ve used a lot of peptide serums over the years — many of them sound impressive but don’t deliver much beyond temporary hydration. Medik8 Liquid Peptides Advanced MP is different. This is a genuinely smart, well-formulated serum that earns its place through consistency and results. The texture is lightweight, silky, and absorbs immediately into the skin without any stickiness or residue. It layers beautifully under other serums and moisturizers and never pills. From the first use, my skin feels more hydrated and supported, but what really stands out is how my skin looks with continued use — smoother, more even, and noticeably more resilient. This serum doesn’t try to overwhelm the skin. Instead, it quietly improves overall skin quality. Fine lines look softened, my skin feels firmer and better hydrated, and there’s a subtle refinement to my complexion that makes everything else in my routine work better. It’s especially good for skin that’s starting to lose bounce and elasticity — which is exactly where I am now. I also really appreciate how gentle this is. There’s no tingling, irritation, or sensitivity, even when I’m using other actives like retinoids in my routine. It plays well with everything and feels like it’s strengthening the skin rather than pushing it too hard. This feels very true to Medik8’s clinical, results-driven philosophy: no hype, no unnecessary extras, just thoughtful formulation and visible improvement over time. If you’re looking for a peptide serum that delivers real, cumulative benefits — especially for mature or post-menopausal skin — this is an excellent choice. I’ll absolutely keep this in my routine.

Be aware that the bottles are tiny. It has no smell to it and really leaves my skin feeling plump and moisturized without irritation. I use two pumps a day and the bottle is still going strong two months later, so decent value. This is the best peptide serum I’ve found. The collagen proteins really make a difference.

After researching the best peptides for mature skin, I went with this (it’s highly recommended) and am enjoying it. It gives nice lightweight hydration and protection (I even use it as a base before putting on tretinoin.) My skin looks fresher, plumper, and ‘glowier’

Love this. It is expensive and a little goes a long way. I use this in the evenings and it is gentile and works great. This is my second bottle and I will buy it again.

This is one of the best peptide serums I’ve ever used. My skin looks firm and flawless when I use this product. I layer it with their Crystal Retinal. Very beautiful product. Will repurchase!

Excellent product! Need less than a pea size. Like the pump dispenser. It’s a lightweight milky serum that absorbs instantly with no residue. Does not make me oily nor clog pores. No weird odor. Layer vitamin C serum after peptides and get a great rosy glow. Also use after derma-rolling with no irritation. Using twice daily and my nearly 60 yoa complexion looks more firm, smooth and healthy. Very happy to invest in a quality product that delivers results!

The serum is amazing but the Amazon delivery is terrible. My box was opened, see photo, and missing the cap. I don’t know if I trust using it. So disappointed!!

I really love this serum it actually works! The peptides it contains are the absolute best for anti-aging skincare, the formula is light/milky and spreads nicely over my skin - i find this to be non greasy, lightly moisturizing, and absorbs quickly which is a huge plus. I’m almost 48 and this has really improved my fine lines and I feel like it’s firmed my skin up and my skin tone seems a lot more even as well. It really does what they say it will do which to me makes it worth the higher price tag. The packaging is great, it looks nice, the pump top always gives me the right amount of serum each time so I’m pleased with my purchase and will keep this in my routine permanently. I do use this both AM/PM
