The Science of NAD+
What Is NAD+ and Why Does Your Skin Need It?
NAD+ (Nicotinamide Adenine Dinucleotide) is one of the most talked-about anti-aging ingredients in modern dermatology. It is a coenzyme naturally present in every cell of your body that plays a critical role in cellular energy production and DNA repair. As we age, NAD+ levels in the skin decline significantly, leading to reduced cell turnover, loss of elasticity, and the formation of fine lines and wrinkles.
The Solvea NAD+ EGF Firming Serum replenishes these vital coenzymes, activating the skin's natural renewal process and supporting the production of collagen and elastin. Combined with EGF Peptide, Low Molecular Collagen, and 8 Peptides, it delivers a comprehensive anti-aging treatment that addresses every visible sign of aging through multiple pathways simultaneously.

What is NAD+ and how does it benefit the skin?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme naturally present in every cell that plays a critical role in cellular energy production and DNA repair. As we age, NAD+ levels decline, leading to reduced cell turnover and visible signs of aging. Topical NAD+ supports the skin's natural renewal process, helps boost the look of firmness and elasticity, and supports a more youthful-looking complexion.
What is EGF and what does it do?
What is EGF and what does it do?
EGF (Epidermal Growth Factor) is a naturally occurring protein that stimulates cell growth and renewal. In skincare, EGF Peptide helps support lifted appearance and skin firmness care by encouraging the skin's natural regeneration process. It is particularly effective for improving the appearance of fine lines, wrinkles, and loss of firmness.

How does this compare to other anti-aging serums?
Most anti-aging serums target one or two pathways. The Solvea NAD+ EGF Firming Serum targets multiple simultaneously: NAD+ for cellular renewal and elasticity, EGF for firmness and lift, Low Molecular Collagen for plumping and density, and 8 Peptides for comprehensive line and wrinkle care. The result is a more complete anti-aging treatment in a single serum.

Real reviews from real customers
I have totally changed my skin with this serum. I truly feel like it has made my skin smoother, brighter, and my fine lines are noticeably reduced. It has been one of the most effective serums I have ever used. I use it every night and the results just keep getting better.
I am 49 and this product works very well on my skin. It saturates and I can see a difference in just two weeks. My skin looks more refreshed and the texture has improved significantly. The tightening effect is real. I love the way it feels on my skin, almost like a facelift but soft.
Very lightweight and absorbs quickly without feeling sticky. Leaves my skin feeling smooth and hydrated by morning. Layers well with other skincare without pilling. A little goes a long way. My skin feels firmer and the lines seem less noticeable after just a few weeks of consistent use.
Great product. I can already see a difference in the texture of my skin. Very hydrating and great as part of a nighttime routine. I have noticed that I get a nice glow and it does not irritate my skin at all. Pairs well with my SPF and other skincare products.
I have been using this for a few weeks and I can tell my skin is glowing. It also leaves my skin looking dewy and gives the glass skin look. Gentle on my skin, unscented and smoothing. My skin looks and feels firmer and more radiant. This is now a permanent part of my routine.
