Peptides Emerge as a Celebrity Favorite in Anti-Aging Skincare

A growing number of celebrities, including Jennifer Aniston and Hailey Bieber, are incorporating peptides into their beauty routines, driving a surge in popularity for these protein fragments in anti-aging skincare. Whether used in injectable forms for weight loss or muscle enhancement, or applied topically to target specific skin concerns, peptides are becoming a staple in the pursuit of youthful complexions.

Peptides are short chains of amino acids that function as biological messengers, signaling the body to perform specific actions. In skincare, synthetic versions are formulated to address issues like dehydration, loss of firmness, and the appearance of wrinkles. These ingredients are categorized into four main types: Signal peptides, which stimulate collagen and elastin production; Neurotransmitter-Inhibiting peptides, which relax expression lines; Carrier peptides, which deliver essential minerals to the skin; and Enzyme-Inhibiting peptides, which help prevent age- and environment-induced damage and hyperpigmentation.

Celebrities like Gwyneth Paltrow have discussed peptide treatments on podcasts, while Aniston has openly stated her enthusiasm for them. This celebrity endorsement has propelled peptide-infused products into the mainstream. Brands are releasing a variety of new offerings, including Drunk Elephant's Kamo Triple-Peptide Cover Drops, Lion Pose's Pep Melt Cleansing Barrier Balm, and Plated Skin Science's Body Serum.

Hailey Bieber, founder of Rhode, has been an early adopter, with her Peptide Lip Tint gaining cult status. She also utilizes needle-based peptides and peptide gummies for hair health. Aniston has integrated peptides into her LolaVie haircare line, featuring a proprietary Biomimetic Peptide Pro3 technology in her Intensive Repair Treatment.

Plastic surgeon Dr. Jason Diamond, who has over 20 years of experience with peptide treatments and whose Metacine product line has a celebrity following, emphasizes their efficacy. "I will continue to develop and offer cutting-edge topical peptide treatments to my patients and Dr. Diamond’s Metacine customers," he stated.

Among the trending peptides is copper-binding GHK-Cu, which falls into both Signal and Carrier categories and is available in injectable and topical formulations. While copper peptides are not new, the buzz around GHK-Cu is significant. "There is a substantial — and continuously growing — body of research to support their benefits in skin care," Dr. Diamond commented. "They’ve been shown to work synergistically alongside a larger network of ingredients to benefit the skin."

Joe Basham, senior scientific communications manager at Deciem, the parent company of the NIOD brand, notes the growing interest in copper peptides, particularly GHK-Cu. "The science has always been compelling to us," he said. "Copper peptides, particularly GHK-Cu, are naturally present in the body where they help support processes like collagen production, repair and skin renewal. As those levels naturally decline with age, we see an opportunity to support the skin by working with its biology, not against it."

Peptides are also being incorporated into innovative product applications, such as Metamorphosis Light Therapy's Energize Red Light Activator Serum, which aims to maximize the benefits of red and near-infrared light therapy. Additionally, neuroscientist Sunbin Song, director of research and education for Maelove, noted that certain peptides, like argireline, may extend the effects of Botox, potentially allowing users to go longer between treatments.

Examples of popular peptide products include the Biodance Collagen Peptide Jelly Serum Mist, Meri Stori Silk Peptide Lip Treatment, Peter Thomas Roth Peptide Skinjection Peptide-Infused Face and Eye Tape, Pareva GFP12 Collagen Eye Serum, Timeless Matrixyl Synthe’6 Serum, and Maelove's own peptide-focused offerings.
