Advanced Repair for Aging Hands, Powered by the Longevity Molecule.

SANTA MONICA, Calif., Oct. 1, 2026 /PRNewswire/ — Oak Essentials, the clean, hydrating skincare line by Jenni Kayne, launches Antioxidant Hand Serum, a targeted serum formulated for the skin that shows signs of aging first. Powered by antioxidant-rich Grapevine Stem Cells, a source of Resveratrol, also called the longevity molecule, the silky, fast-absorbing formula helps visibly reduce dark spots and soften the appearance of wrinkles while lightly hydrating for supple, youthful-looking hands.

Created with ingredients of 96% natural origin, Antioxidant Hand Serum launches Oct. 1 at $38 and joins the Jenni Kayne x Oak Essentials Hand Wash and Hand Balm in the Oak Essentials hand care collection.

“At this stage of life, caring for my hands feels just as important as anything I put on my face,” said Jenni Kayne, Founder of Oak Essentials.

Antioxidant Hand Serum absorbs quickly with no tacky residue and layers seamlessly under moisturizer or SPF, leaving hands looking visibly smoother, more even-toned and supple. It is gently scented with Oak Essentials’ Cashmere Musk, with notes of calming Lavender and warm Musk grounded by an earthy Vetiver base.

“The hands are always the tell,” said Lauren Harris, CEO of Oak Essentials. “We wanted to give them the same serious, results-driven care we bring to every face product.”

Suitable for all skin types, including sensitive skin, the formula targets dark spots, wrinkles and fine lines, dehydration, loss of elasticity, uneven texture, and mature or changing skin. Key ingredients include:

• Grapevine Stem Cells: Rich in Resveratrol, help visibly reduce the appearance of dark spots and soften the look of wrinkles.
• Rosehip Oil: Naturally high in Vitamin A, Vitamin C and Omega fatty acids, helps replenish hydration, reinforce the skin barrier and reduce transepidermal water loss.
• Botanical Stem Cells: A biotech blend of Hollyhock and Lingonberry Stem Cells that helps support elasticity, visibly improve firmness and protect against daily environmental stressors, including UV exposure and pollution.
• Bamboo Juice: Naturally rich in silica, amino acids and trace minerals, helps deliver lightweight, lasting hydration.
• Lingonberry Fruit Extract: Concentrated with polyphenols and Vitamin C, helps defend the skin against oxidative stress.
• Pullulan: A naturally derived film former made from fermented tapioca that visibly smooths the appearance of fine lines on contact.

“Hands were the brief, but this had to be serum-grade, not a dressed-up lotion,” said Kim Price, COO and Head of Product Development at Oak Essentials. “We built around Grapevine Stem Cells because the science was genuinely compelling, then layered in Rosehip Oil and Botanical Stem Cells until we had something that delivers the way a face serum does—just for hands.”

Antioxidant Hand Serum (1.7 oz / 50 mL, $38) is available now at oakessentials.com/products/antioxidant-hand-serum.
