Research has shown that supplemental collagen—especially marine collagen peptides—can reduce signs of wrinkles, tighten loosening skin, and improve skin elasticity and hydration.
To increase skin's elasticity, firmness, and texture, and help prevent fine lines and wrinkles, studies show that taking up to 2.5 grams is effective. Here's a caveat: most users will find that they need less than 2.5 grams of hydrolyzed collagen to see skin-benefiting results.
Loose skin can be problematic, but there are multiple ways to minimize or reduce it. Collagen is a huge factor in the skin's elasticity. Boosting your body's collagen production is one way to reduce loose skin.
Are collagen supplements a good option for tightening loose skin? A: Collagen supplements aren't the best option if you want to improve the appearance of your skin. That's mainly because there's no evidence-based science to prove they work ― or that they're safe.

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.
Type 3/Type III: Type 3 collagen is made of reticular fibers and a major component of the extracellular matrix that makes up our organs and skin. It's usually found with type 1 and helps give skin its elasticity and firmness.
One review of 11 studies focusing mostly on women found that taking 3–10 grams of collagen per day for an average of 69 days led to improvements in skin elasticity and hydration ( 6 ). These supplements may work by stimulating your body to produce collagen on its own.
Fish, or “marine”, collagen contains 90% Type I and 10% Type III collagen. These are the two main types of collagen in the skin. Therefore, they are the best types of collagen for eliminating wrinkles and sagging skin.
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.
There are three main vitamins that help your skin stay elastic by protecting it from the sun, according to a May 2015 study in Biomolecules & Therapeutics: vitamin A, vitamin E and vitamin C. All three are antioxidants, although they play different roles in skin care.
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.)
One such option is exercising. Any workouts that build muscle mass or tighten muscles — especially around the stomach — can reduce the appearance of loose skin.
#1 Retinol
Exfoliation – Exfoliation improves skin cell turnover. As dull, dead layers of skin fall away, fresh, glowing skin is revealed. Improved skin fullness – Retinoids stimulate collagen production, which helps diminish wrinkles and sagging, and leave skin looking fuller and tighter.
For skin health, you should look toward types 1 and 3, and for joint health, go for type 2 collagen.

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 ).
Retinol (vitamin A) is the most frequently used ingredient in anti-aging creams. But tretinoin, another form of vitamin A, may be the most effective ingredient to firm the skin on your neck and face.
