As a board-certified dermatologist, a skin-cancer specialist, and a reconstructive surgeon who has worked on over 10,000 patients, Dr. Antony Nakhla has witnessed firsthand the remarkable ways skin is able to heal and regenerate itself time and again. This experience inspired him to conceive a line of products that would support skin’s inherent repair processes through the science of bioidentical innovation. That brand is Eighth Day, named for the concept of renewal that comes after the seven-day weekly cycle of time.
“The science behind Eighth Day was conceived when I made the connection between the bioidentical dressings and bandages I use to heal open wounds for my skin cancer patients and the transformative effects these same ingredients could have on skin regeneration,” says Dr. Nakhla. At the center of this science is its Peptide-Rich Plasma, a proprietary, patent-pending technology made up of 24 bioidentical peptides, amino acids, and growth factors that help trigger renewal and restoration at the cellular level.
That science also powers the brand’s newest innovation: the Ultra-Rich Intensive Moisturizer. “Our goal is to extend skin’s functional health and longevity—its ability to regenerate, retain density, and resist depletion,” says Dr. Nakhla. Developed for dry or mature skin, or for individuals experiencing volume loss due to aging or fluctuations in weight, this cream is meant to provide not only surface hydration benefits but deeper rejuvenation. The brand’s clinical results show that after four weeks of use, it improves volume, lines, wrinkles, firmness, elasticity, moisturization, and radiance. Its texture is indulgent yet purposeful—rich at first touch, it then melts into skin, leaving behind a supple finish with a luxurious feeling. The Ultra-Rich Intensive Moisturizer can be used on the entire face, neck, décolleté, and eye area, morning and night.
The secret to the cream’s results lies in its insightful blend of next-generation ingredients. In addition to the Peptide-Rich Plasma, the formula contains the brand’s proprietary VolumatrixSubQ, a biotechnology designed to mimic the appearance of natural fullness by supporting collagen and promoting the skin’s own lipid renewal for a visibly plumper and smoother appearance over time. It’s clinically shown to slow fat loss in the skin by up to 29 percent, targeting age- or weight loss–related density depletion. The moisturizer also features three molecular weights of hyaluronic acid, to hydrate deeply and deliver instant softness and bounce.
The Ultra-Rich Intensive Moisturizer is the perfect complement to Eighth Day’s Regenerative Serum, the brand’s hero product. It packs in the line’s highest concentration of Peptide-Rich Plasma to address 10 visible signs of skin aging, including fine lines and wrinkles and the loss of volume, firmness, and elasticity.
For the brand’s founder, this moisturizer is more than just an everyday cream; it’s a transformative treatment. “Building cellular longevity requires consistency, not extremes,” says Dr. Nakhla. “This formula is designed to support the kind of daily intervention that creates long-term change.”
