The Edit with Eighth Day Founder Dr. Antony Nakhla
Powered by cutting-edge science and skin-regenerative technology, Eighth Day delivers clinical-level results with a luxurious touch. Founded by Dr. Antony Nakhla, a dermatologist and skin cancer surgeon, the brand harnesses its proprietary Peptide-Rich Plasma® technology - an advanced blend of peptides, growth factors, and amino acids - to repair, renew, and restore skin at a cellular level. From targeted serums to transformative cleansers, each formula is meticulously crafted to address visible signs of aging while supporting long-term skin health.
1. For someone new to Eighth Day, which product is the perfect introduction to the line?
I always recommend starting with The Regenerative Serum. It is our hero product, and it embodies everything Eighth Day stands for—science-driven, multi-tasking, and clinically proven. It addresses ten visible signs of aging in one step, so you can simplify your routine while seeing real results.
2. Can you explain the science behind your Peptide-Rich Plasma® technology and why it’s so effective?
Peptide-Rich Plasma® is our proprietary, patent-pending technology composed of 24 bioidentical peptides, amino acids, and growth factors. These are the essential building blocks of healthy skin. Peptides act like architects, directing how the skin repairs and rebuilds itself. Amino acids are the raw materials that give structure and resilience. Growth factors are the messengers that signal cells to behave younger and renew more effectively. Because these molecules are bioidentical—meaning the skin recognizes them as its own—they can communicate directly with cells in their native code, activating true regeneration rather than offering surface-level change.
3. How do Eighth Day products address both immediate and long-term skin concerns?
We design every formula to deliver results you can feel right away and benefits that build with time. Our Regenerative Serum is a great example—it provides instant hydration and radiance, while its concentration of Peptide-Rich Plasma® works over weeks to restore firmness, smooth fine lines, and support long-term skin resilience. That balance—visible improvement today and continuous renewal for tomorrow—is at the heart of Eighth Day’s approach.
4. Which products do you personally use the most, and what results have you seen?
The Regenerative Serum is the anchor of my routine—I use it every day. Depending on how my skin feels, I’ll add The Resurfacing Tonic for a brighter, smoother texture, followed by the moisturizer that best fits my needs based on the season. At night, I use The Night Cream Treatment, which delivers our proprietary RetinalXR™—a next-generation retinoid and the gold standard for anti-aging—at high potency with far less irritation. In the morning, I always finish with the Rejuvenating Moisturizing Primer SPF 30. As a skin cancer surgeon, sunscreen is non-negotiable for me regardless of the season, and is the most important anti-aging habit you can adopt.
5. Are there any tips for layering Eighth Day products for the best results?
Yes—simplicity and consistency matter more than the number of steps. I recommend starting with The Resurfacing Tonic to exfoliate and purify the skin, then The Regenerative Serum, followed by your moisturizer of choice, which may shift depending on the season or climate. At night, The Night Cream Treatment is an advanced retinoid to smooth and brighten, and it can also double as a moisturizer. In the morning, follow with our Rejuvenating Moisturizing Primer SPF 30, which doubles as sun protection and a base for makeup. Generally speaking, apply textures in order from thinnest to thickest: apply tonics and serums first, then moisturizers. But the strength of our formulas is that each one is multi-tasking—so even a streamlined routine delivers comprehensive results.
6. Who is the perfect candidate for Eighth Day? What are their skin struggles and hopes?
Above all, the Eighth Day customer wants something that works. Many of our clients have tried countless products and are looking for solutions that actually deliver visible change. They also value an elevated experience—textures that feel good on the skin and packaging that looks beautiful on their vanity. And because they tend to lead busy lives, they appreciate that our products are multi-tasking and designed to streamline routines without sacrificing results.
