Conclusion. Caffeine reduces collagen synthesis in human cultured skin fibroblasts.
"It's worth remembering that coffee doesn't destroy collagen, it inhibits its production," says nutritional therapist at the Pulse Light Clinic, Lisa Borg.
Quitting coffee can increase the growth of collagen and makes look healthy and makes it glow. Moreover, the dehydration can cause premature aging and a caffeine detox can lead to a beautiful change in your skin quality. Coffee can also increase oil production in the skin and cause our pores to get clogged due to this.
“Coffee contains caffeine, which has a diuretic (water losing) effect, so drinking coffee (even decaf) can make you and your skin dehydrated and saggy,” she says. “Drinking coffee has also been shown to reduce skin circulation by constriction blood vessels.
The collagen tissues support the formation of bones, tendons, and cartilage that form depending on the level of mineralization. However, an individual can lose collagen components in the body due to exposure to ultraviolet light, tobacco, excessive intake of sugar, and aging.
How can I naturally rebuild collagen? You can naturally support the collagen production process by using topicals such as vitamin C and retinol, collagen peptide supplements, eating a nutrient rich diet, and avoiding habits that damage the collagen (such as poor sleep and sun exposure.)
So what's the best way to rebuild collagen in your face? Tretinoin, a prescription-grade retinoid, is an excellent treatment for rebuilding collagen. Almost 30 years ago, a small study showed that tretinoin application increases collagen by up to 80% in the skin after 1 year of treatment.
Not only does modern research show that drinking coffee might help you live longer, it also shows that caffeine could play an important role in slowing down the effects of aging. That's right—the active ingredient in coffee that most of us think of as a helpful stimulant could also be a powerful anti-aging substance.
Foods For Skin Elasticity
Eating foods like greens, fatty fish, citrus fruits, broccoli, almonds and walnuts can replenish elastin in your skin. These foods are known to work from within to improve your skin's health. Don't forget antioxidant foods  like green tea and berries as well.
Not partaking in caffeine can be good for your blood pressure. Caffeine has been shown to raise blood pressure levels due to the stimulatory effect it has on the nervous system. High intake of caffeine — 3 to 5 cups per day — has also been associated with increased risk of cardiovascular disease.
If caffeine is a big part of your daily diet, taking it away can have a host of unpleasant effects in the short term. These include headache, tiredness, sleepiness, down moods, trouble concentrating, and crankiness. You'll start to feel symptoms a day or two after you stop. They can last anywhere from 2 to 9 days.
The high acidity of coffee can interfere with your hormones and impact the amount of oil your skin produces. Coffee drinks with dairy products increase your risk of developing acne. Dehydration from coffee and other drinks such as soda or alcohol may also cause skin redness or inflammation.
Besides time, three main things will lower your collagen levels: sunlight, smoking, and sugar. Too much exposure to ultraviolet light makes its fibers unravel. This can lead to sun damage, such as wrinkles. Many of the chemicals in cigarette smoke can damage it, which can make skin sag and wrinkle.
A diet full of protein-rich foods, whether from plant or animal sources, can help supply these critical amino acids. Other nutrients that aid the process of collagen production include zinc, vitamin C, and copper. So, fruits and vegetables high in vitamins and minerals are also a friend to supple skin.
“Caffeine is like any other diuretic; it can make you excrete fluid, and deplete your body of moisture”, says Dr. Hirsch. “Anything dehydrating can dehydrate your skin, making it look dull and aged”.
Drinking two to three cups of coffee a day was linked to the largest reduction in early death, compared to people who drank no coffee, according to the statement. Ground coffee consumption lowered the risk of death by 27%, followed by 14% for decaffeinated, and 11% for instant caffeinated coffee.
So while drinking coffee itself won't likely make your skin look younger, caffeine can, there is nothing wrong with drinking coffee in moderation, even if the act of drinking it won't really help you appear any younger. There are several other health benefits of coffee that make it worthwhile to drink in many cases.
Of course, you can't reverse the signs of aging completely. You can go the nonsurgical route and add firming creams or facial exercises to your skincare routine. There are also cosmetic procedures that provide quicker results, such as laser surfacing or ultrasound skin tightening.
Ultraviolet rays, aka sunlight, cause collagen to break down faster. With sun exposure, those UV rays damage the skin by entering the dermis (the second and thickest layer of our skin) which causes collagen to break down faster.
Slather on a vitamin C serum in the morning. The vitamin is an antioxidant that protects the collagen in your skin against UV damage, says Chwalek. More than that, she says, it triggers collagen formation and stabilizes the collagen proteins in skin.
