What's Inside

How To Use

Assorted citrus fruits including orange, lime, and lemon on a wooden board.

These four forms of vitamin C derivatives—L-ascorbic acid, 3-glyceryl ascorbate, tetrahexyldecyl ascorbate, and magnesium ascorbyl phosphate—work synergistically to provide comprehensive skincare benefits. L-ascorbic acid delivers immediate antioxidant protection and stimulates collagen production, while 3-glyceryl ascorbate hydrates and supports mild antioxidant activity, making it suitable for sensitive skin.


Tetrahexyldecyl ascorbate penetrates deeply into the skin, enhancing collagen synthesis and reducing oxidative stress, and magnesium ascorbyl phosphate offers stable, gentle brightening and anti-aging effects. Together, these derivatives provide a multi-layered approach, ensuring both immediate and sustained skin benefits with enhanced stability, hydration, and anti-aging support, making them practical for a wide range of skin types.

    The Best serum!

    I have very sensitive, combination skin that becomes especially reactive and prone to breakouts during my menstrual cycle. Finding products that actually soothe and balance my skin — without causing irritation — has always been a challenge.

    From the very first use of the Longevity Hybrid Defense Serum, my skin quite literally thanked me. The texture felt luxurious, lightweight, and calming, and within just a few days, I began to notice real transformation.

    My skin tone became more even, redness noticeably diminished, and even post-acne marks started to fade. It was as if my skin finally found the support it needed to truly heal and glow.

    I’m absolutely in love with this serum — the results speak for themselves. It has become a staple in my skincare routine, and I can genuinely say it’s one of the few products that has exceeded my expectations.

    Thank you so much to Meticulous Skincare for creating something so effective, elegant, and skin-friendly. This is more than just skincare — it’s skin therapy.

    Perfect!!!

    I’ve been using the Longevity Hybrid Defense Serum for a few days now, and I’m already impressed! The texture is lightweight and absorbs quickly without leaving any sticky residue. My skin feels noticeably smoother and more hydrated. I love that it’s packed with antioxidants and peptides – it really feels like it’s giving my skin that extra layer of protection and support. Excited to see the long-term results!

    I've finally found it—a complete skincare treatment for my face, all in one bottle. Since I started using the Meticulous Skincare Serum, my routine has become so much simpler yet so much more effective. It feels like this serum understands exactly what my skin needs. Hydration, balance, glow—it delivers everything. My skin has never felt so well taken care of. I’ve upgraded my entire skincare game with just one product—a total game-changer.

    Definitely loved that

    I've been using the Longevity Hybrid Defense Serum for a few weeks now, and I'm genuinely impressed. It absorbs quickly, feels lightweight on the skin, and gives an instant glow. My skin looks more hydrated, smoother, and noticeably more even-toned. I love how it protects and nourishes at the same time—definitely a new staple in my skincare routine!

    Love Longevity Hybrid Defense Serum!

    I’ve using this serum for a month now and absolutely love the plump and glow it gives to my skin! Also, my pores got visibly smaller even after a few uses!
