As you age, your body produces less collagen, leading to dry skin and the formation of wrinkles ( 5 ). However, several studies have shown that collagen peptides or supplements containing collagen may help slow the aging of your skin by reducing wrinkles and dryness.
One of the most well-known benefits of collagen is its ability to give skin a healthy glow. Collagen does this by providing elasticity to the skin, which helps it to appear plump and youthful.
Oral intake of low-molecular-weight collagen peptide improves hydration, elasticity, and wrinkling in human skin: a randomized, double-blind, placebo-controlled study.
Collagen is not an effective acne treatment option. Taking collagen supplements may have some benefits for aging skin, but there's no indication that collagen can prevent blemishes, reduce pimples, or alleviate post-acne scarring.
Research has shown indicated that adults can safely consume between 2.5 to 15 grams of collagen a day. Read the label on your supplement to see how much it contains. Many people take 1-2 tablespoons of collagen powder per day.
Some studies show that taking collagen supplements for several months can improve skin elasticity, (i.e., wrinkles and roughness) as well as signs of aging. Others have shown that consuming collagen can increase density in bones weakened with age and can improve joint, back and knee pain.
Improvements in skin, nails, muscle and joint health may become noticeable after three to six months of regular collagen supplementation, but results varied across scientific studies. Results may take longer depending on personal factors including age, nutritional status and overall health.
As such, no matter your goal for using collagen, it will take at least 8 weeks to experience noticeable results ( 6 ). Most studies use a minimum of 8 weeks to assess collagen's effects on skin health and joint pain relief, but other studies use longer periods, such as 12 months, for bone health ( 9 , 14 , 22 ).
Indeed, an independent study conducted in 2019 found collagen supplements to show promise in terms of improving skin elasticity and dermal collagen density.
“There's no evidence to suggest that taking collagen by mouth actually benefits in any way in terms of improving collagen production.”
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.)
Does Collagen Tighten Saggy Skin? Studies have indicated that supplemental collagen is beneficial for skin health, including tightening sagging skin (known as elasticity), boosting hydration, and lessening the appearance of wrinkles.
While there is no conclusive evidence that using collagen boosters improves skin health or thickens the skin, some people find them beneficial. Eating a balanced diet can help support overall health.
Current research reveals that collagen use could result in a reduction of wrinkles, rejuvenation of skin, and reversal of skin aging [16], which may improve skin hydration and elasticity [17].
Collagen is an incredibly important protein that keeps your tissues and bones together. Specifically for your skin, collagen helps give your skin structure and elasticity, or that famous “bounce.” So, in theory, boosting your skin's collagen levels — or preventing its loss — would help you look younger.
Collagen does not help with body fat because you cannot reduce fat in specific areas of your body. You can lose weight using collagen rich foods like bone broth, but it will not specifically target your belly fat.
What is the best collagen for the skin? There are many types of collagen, but there are 3 that are found most commonly in the body. Type I and type III are generally found in skin, so they're considered the best for supporting healthy skin ageing and maintaining a smooth, glowing complexion.

While there are plenty of suggestions floating around, really, the best time of day to take your collagen supplement is whenever works best for you. Suppose you like to take it in the morning, great. If you prefer it as a snack during the day, great, or if you want to take it before bed, that's also great.
Bottom line: Most people have 1 treatment and feel some tightening right away. It takes time for your body to make collagen, so you'll see the best results in about 6 months. Some people benefit from having more than 1 treatment. Results can last 2 to 3 years with the right skin care.
When Is the Best Time to Take Collagen? Some swear by taking collagen in the morning while your stomach is empty to maximize absorption. Others swear by taking it at night so your body has ample time to process the collagen while you sleep.
Collagen prevents skin from sagging and gives it a plump, full look. Elastin helps skin return to its original shape after stretching or compressing.
Collagen supplements may not be safe for: People with fish, shellfish, or egg allergies (collagen supplements may contain these allergens as ingredients)16. People with a Kosher or Halal diet. People with a vegetarian or vegan diet.
If you take too much collagen, it can throw off the balance of amino acids in your body and lead to side effects such as headaches, digestive issues, and fatigue. Additionally, some people may be allergic to collagen or have an intolerance to it.
