Intelligence brief
Share on Pinterest Recent research has found an association between sleep duration and biological aging. Image Credit: ArtistGNDphotography/Getty Images A recent study found that too little or too much sleep may speed aging in the brain and other organs. The study used aging clocks to examine associations between sleep and various mental health and medical conditions. The researchers also found a direct link between sleep and late-life depression. Sleep is an important aspect of overall health and emotional well-being. The amount and quality of sleep you get can affect your body in various ways. The study showed a relationship between sleep and chronic diseases. This suggests that a connection exists beyond brain influence. “Maintaining a consistent wake time is particularly important for stabilizing circadian rhythm . Adherence to good sleep hygiene — especially during the evening wind-down period — is also essential,” he said.

An Injectable Biopolymer Hydrogel Complex (PN/HA/B3) for Facial Skin Redensification and General Rejuvenation: Clinical Report on Device Safety and Efficacy.
J Funct Biomater · May 2026
This study evaluated the safety and effectiveness of HYDRAGEL A2, an injectable medical device containing hyaluronic acid (HA), polynucleotides (PN), and niacinamide, for improving facial skin quality. These ingredients are increasingly recognized for their synergistic effects in aesthetic medicine, with HA and PN providing hydration and skin support, and niacinamide offering anti-inflammatory and antioxidant properties. A prospective, open-label clinical investigation was conducted on 42 female subjects (mean age 45 ± 1 years, Fitzpatrick skin phototypes II-V) to assess skin elasticity, hydration, and mild skin depression correction following cheek area injections.

A Prospective, Randomized, Double-Blind, Vehicle-Controlled Study Evaluating the Efficacy, Safety, and Patient Satisfaction of Tretinoin 0.05% Lotion for Chest Rejuvenation.
J Drugs Dermatol · Jun 2022
There is increasing interest in non-invasive options for chest rejuvenation with minimal to no downtime. Topical retinoids have long been used to correct photoaging due to their ability to promote epidermal hyperplasia, matrix metalloproteinase inhibition, collagen synthesis, and dispersion of melanin granules. Topical retinoid use is often limited by the ensuing irritation that occurs with initial use and resolves after about one month.
