Aging is a normal process linked to specific patterns and changes in the epigenome, particularly DNA methylation. Harnessing epigenetic mechanisms and understanding the epigenetic clock might enable us to slow or reduce human aging in the future, especially as scientific research reveals new associations and insights.
After DNA methylation patterns have been established during embryogenesis, researchers investigate how they are maintained, and how the environment can influence changes to marks on top of DNA during one’s lifespan.
For years, scientists have studied why some organisms live longer than others. While genes play an important role in aging, research continues to show that lifespan is not determined by DNA sequence alone. The way genes are regulated, through epigenetic marks that help turn genes on or off, may also influence how organisms age and, in some cases, how certain biological effects are passed to future generations. A study from researchers at Howard Hughes Medical Institute’s Janelia Research Campus adds [more…]
Skin aging is commonly divided into two categories: intrinsic aging, which reflects the natural decline of cellular function over time, and extrinsic aging, which results from environmental stressors such as UV radiation, pollution, oxidative stress, and lifestyle factors. While these categories describe the sources of aging-related damage, they do not fully explain the molecular mechanisms that cause skin cells to progressively lose their youthful repair capacity. One emerging proposed concept is skin epigenetic hydroxylation incompetence, or SEHI. This idea suggests [more…]
The human gut is one of the body’s fastest-renewing tissues. Every few days, new cells are produced from intestinal stem cells to help maintain the lining of the gut. However, a study suggests that, with age, some of those stem cells may begin to carry an epigenetic pattern linked to important genes becoming less active. Researchers from the Leibniz Institute on Aging – Fritz Lipmann Institute in Germany, the Molecular Biotechnology Centre in Turin, and the University of Turin found [more…]
As skin ages, it may become more sensitive to its environment. A small amount of sun exposure can cause redness more quickly. A product that once felt gentle may suddenly feel irritating. Dryness, uneven tone, inflammation, or slower recovery may also become more noticeable after stress, weather changes, or environmental exposure. These changes are often treated as surface-level skincare concerns, but they may also reflect deeper biological shifts. Epigenetic mechanisms help regulate skin homeostasis, regeneration, senescence, and both natural and [more…]
Two people can be the same chronological age, yet their skin may appear to age at very different rates. One person may develop fine lines, dryness, uneven pigmentation, or slower wound healing earlier than expected, while another may show these changes more gradually. This difference is often described as accelerated skin aging. Rather than being a separate process, it reflects a faster progression of the same biological changes seen in normal skin aging. These changes are shaped not only by [more…]
Your skin is often the first place where aging becomes visible. Fine lines, dryness, uneven tone, and slower healing can appear long before other signs of aging are noticeable elsewhere in the body. But these changes are not only happening at the surface. Beneath the visible signs of aging, skin cells undergo molecular changes that affect how they function over time. One important change involves DNA methylation, an epigenetic process that helps regulate gene activity. Research suggests that DNA methylation [more…]
Skincare has been moving steadily away from one-size-fits-all routines and toward measurement-led personalization. One reason is a growing recognition that chronological age does not always match biological indicators of skin condition. Reviews of intrinsic and extrinsic aging factors highlight how UV exposure, pollution, lifestyle, metabolism, and genetics can shift how skin looks and functions over time. Against that backdrop, at-home testing tools are emerging to help consumers quantify skin-aging signals rather than relying only on visible changes. One framework being [more…]
Consumers often describe a familiar problem: skin that seems to lose firmness, glow, and smoothness earlier than expected, even with consistent use of serums and creams. Researchers and brands typically group these concerns under “accelerated skin aging” — a pattern where visible aging signs appear or progress faster than a person’s chronological age might suggest. As “epigenetic skincare” grows as a theme across the industry, it has also drawn skepticism, mainly because epigenetics is frequently used as a broad label [more…]
Autophagy is the eukaryotic cell’s waste management system; it collects and recycles damaged organelles and proteins. Unlike eukaryotic cells, bacteria lack lysosomes—the specialized structures that perform this task—so they rely on simpler methods to manage waste. More memorably, autophagy can be thought of as controlled cannibalism. From Greek, the word translates to “self-eating.” In mammals, it takes three principal forms: micro, macro, and chaperone-mediated (Shu, 2023). Of the three, macroautophagy is the best studied. In a healthy body, autophagy assists [more…]
“To lengthen thy life, lessen thy meals.” – Benjamin Franklin. For millennia, fasting has been lauded as a path to discipline, purity, longevity, and mental acuity. While Franklin may not have always heeded his own advice, his contention, one shared by many cultures throughout history, is now backed by over eight decades of scientific research. Caloric restriction (CR) is the most thoroughly studied longevity intervention to date. In humans and animals, it consistently increases lifespan and healthspan (McDonald, 2010). Any [more…]
