Selma Blair and ESK Launch First-Ever Collaboration with Innovative Ultimate A Gold Night Cream

From Brand Fan to Formulator, A Skincare Partnership Rooted in Science and Purpose

NEW YORK, Sept. 24, 2025 /PRNewswire/ -- ESK, the Australian evidence-based cosmeceutical skincare brand, today announced its first-ever product innovation co-developed with actress, activist and wellness advocate, Selma Blair. Introducing Ultimate A Gold, a cutting-edge night cream designed for sensitive, mature, and reactive skin.

More than a celebrity endorsement, this co-creation marks Blair's debut in skincare, born from a personal skin health journey, and built on a shared commitment to integrity, science and results.

Struggling with autoimmune-related skin sensitivity that most products couldn't solve, Blair discovered ESK and experienced a dramatic transformation with the brand's science-backed offerings. What began as a personal success story quickly evolved into a hands-on partnership with ESK founder and physician, Dr. Ginni Mansberg.

Together, the duo co-developed Ultimate A Gold, a next-generation evolution to one of ESK's hero products, with Blair actively involved in product formulation, testing, and packaging.

For Selma, this launch signifies a mission-aligned entry into the skincare space, backed by data, not just branding.

"I wanted to help build something for people like me with incredibly sensitive skin," said Selma Blair. "Ultimate A Gold is personal, powerful, and rooted in real science."

For ESK, the collaboration represents a pivotal strategic moment: a move to strengthen the brand's US presence, aligned with a globally recognized partner who embodies the brand's values of transparency, science, and integrity.

"From the very first conversation with Selma, it was clear this wasn't going to be a typical celebrity collaboration. Selma brought not only her personal story of struggling with sensitive, reactive skin, but also a genuine passion for science and integrity in skincare," said Dr. Ginni Mansberg. "Together, we created Ultimate A Gold - a night cream that delivers clinical-level results while remaining gentle enough for the most delicate skin. This launch represents everything ESK stands for: evidence, transparency, and results without compromise."

As ESK's most advanced night cream, Ultimate A Gold features a powerful, yet gentle formula designed to reduce visible signs of aging, improve skin texture, fade pigmentation, increase skin hydration and strengthen the skin's barrier function. Building on the cult-favourite Ultimate A, this breakthrough elevated formula features a hero lineup of clinical-level actives tailored specifically for sensitive, mature, and reactive skin types - delivering real results without compromise.

Setting this launch apart from others through authenticity and hands-on collaboration, the product features a science-backed formula with true clinical integrity, including:

• Retinal (0.1%) – Gold-standard collagen stimulation without the irritation
• Niacinamide (5%) – Brightens, calms and strengthens the skin barrier
• Lactiobionic acid (5%) – Gentle exfoliation to boost radiance
• 4-n-Butylresorcinol (0.1%) – A powerful ingredient targeting pigmentation and melasma
• Hyaluronic acid (1.5%) - Skin repair and Hydration
• Ceramides (0.06%) - Improved skin barrier

The Selma Blair x ESK Ultimate A Gold is now available for $100 at eskcare.com.
