Skin aging isn’t just about genetics or the creams you use — it’s shaped by your lifestyle choices every day. From how well you protect your skin from the sun to how you sleep, hydrate, and manage stress, these daily habits directly impact collagen production, skin barrier strength, and long-term skin health. If you want to maintain healthy, glowing skin in later life and reduce the appearance of wrinkles and sagging, small, consistent changes can make a meaningful difference.

Anesthesiologist and interventional pain medicine physician Dr. Kunal Sood outlines six simple daily habits that can help slow skin aging while supporting overall healthier, more resilient skin. In an Instagram video shared on Dec. 24, the doctor explains how habits like applying more and less daily sunscreen can help reduce Smoking and alcohol can strengthen the skin barrier, support collagen production, enhance overall skin health and slow cellular aging.
daily spf
According to Dr. Sood, wearing broad-spectrum sunscreen every day is the most impactful habit when it comes to preventing premature aging. He explains, “In a long-term randomized trial, people using sunscreen daily had no detectable increase in skin aging over 4.5 years and about 24 percent less photoaging. SPF blocks UVA-driven oxidative stress and collagen-degrading enzymes that cause wrinkles and sagging.”
quit smoking
Doctors emphasize that smoking accelerates aging by reducing collagen production, increasing collagen breakdown, and increasing oxidative stress. He highlights, “Clinically, wrinkles appear more on the faces of smokers independent of sun exposure. Quitting smoking improves the skin’s biological age, color and texture in just a few months.”
limit alcohol
Dr. Sood emphasizes that excessive alcohol consumption accelerates skin aging by increasing oxidative stress, dehydration, and inflammation, which compromise skin health over time. He explains, “Excessive alcohol consumption is linked to deeper wrinkles, inflammation, visible blood vessels, and loss of mid-facial volume. Mechanisms include oxidative stress, inflammation, dehydration, and decreased skin repair during sleep. Reducing intake helps stabilize hydration and collagen integrity.”
manage stress
Chronic stress is closely linked to hormonal imbalance and oxidative damage, and actively reducing stress can play an important role in slowing skin aging and improving overall skin health. Dr. Sood explains, “Chronic stress shortens telomeres, increases cortisol, disrupts collagen production, weakens the skin barrier, and increases oxidative damage. Human studies link high stress to rough texture and poor hydration. Reducing stress helps slow the signs of cellular aging.”
stay hydrated
According to the doctor, prioritizing hydration and increasing daily water intake can significantly improve skin hydration, elasticity and barrier function – especially in individuals who typically consume very little water. He highlights, “Improved hydration reduces dryness and makes fine lines less apparent.”
gentle skin care
Using harsh skin care products can strip the skin of moisture and cause constant irritation, both of which contribute to rapid skin aging. Dr. Sood explains, “Harsh cleansing and chronic irritation leads to water loss and worsens the ‘aged’ appearance. Gentle cleansing and moisturizers with ceramides and humectants improve barrier function, reduce sensitivity, and support long-term skin elasticity.”
