Christie Brinkley, 72, “loves” the wrinkle-fading serum that Martha Stewart, 84, created to improve skin “tightness.” The legendary supermodel recently shared her enthusiasm for Elm Biosciences’ A3O Elemental Serum, a product developed by her fellow ageless beauty icon. Brinkley’s endorsement adds to the growing buzz around Stewart’s skincare venture.
Christie Brinkley Thirst Trap With a Purpose

Christie Brinkley kicked off her Instagram video with playful energy and a pouty face. “I’m doing the Martha Stewart thirst trap because I’ve been using Elm [Biosciences], and I can do that now,” she announced. “I love the shimmer, I love the texture.” She ended the clip by declaring she needs more of the product, a sentiment many can understand after seeing her radiant complexion.
Christie Brinkley Martha Stewart’s Creation Delivers Results
Stewart previously shared her own positive experience with the serum she helped create. She “noticed an improvement in the texture and the tightness” of her complexion after regular use. At 84, Stewart proves that innovative skincare can deliver visible results at any age.
What Makes This Serum So Effective For Christie Brinkley

The A3O Elemental Serum targets virtually every sign of aging imaginable. The formula increases smoothness, tightness, and hydration while reducing wrinkles, inflammation, sagging, and age spots. Its proprietary A3O complex combines bakuchiol, hyaluronic acid, squalane, and acetyl zingerone—a ginger-derived antioxidant. A patent-pending fatty acid ester delivery system boosts the overall efficacy of every ingredient.
The Secret Behind the Shimmer
Brinkley specifically mentioned loving the product’s shimmer, and there’s science behind that glow. The serum contains a sheer gold tint with pearlescent particles that never look like chunky glitter. Instead, they subtly neutralize imperfections, even out skin tone, and catch light to enhance the appearance of plumpness. It’s an elegant enhancement, not a sparkle overload.
How to Get the Full Brinkley Glow
To completely emulate Brinkley’s luminous look, follow the serum with Supergoop’s Glowscreen SPF tinted primer. She previously told InStyle she loves using it to “add a glow” to her complexion. This combination delivers both skincare benefits and immediate radiance.
The Ultimate Ageless Beauty Routine

Both Brinkley and Stewart prove that great skincare knows no age limits. Their shared enthusiasm for Elm Biosciences highlights a growing trend of celebrities moving beyond traditional endorsements to actually create products they believe in. Stewart’s hands-on approach to formulation gives her brand authenticity that resonates with discerning customers.
