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're taking collagen for the anti-aging benefits, look for type I, or a combo of type I and type III. Both are found in the skin and support skin health (think: improved skin hydration, firmness and texture, as well as fewer wrinkles, per a review study in 2019 in the journal Molecules).
A further 2021 meta-analysis of randomised controlled trials concluded that ingestion of hydrolyzed collagen for 3 months is effective at reducing skin ageing, as it reduces wrinkles and improves skin elasticity and hydration (4).
Type I or type 1 collagen is the strongest type of collagen. If you're looking for a collagen for supporting skin health, type 1 is a top choice since it's literally a building block of the skin.

Jen Says: "My go-to collagen routine is adding Vital Proteins® Collagen Peptides ($27; shop now) in my morning cup of coffee or smoothie – so easy to use."
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.)
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 a protein that serves as one of the main building blocks for your bones, skin, hair, muscles, tendons, and ligaments. "Collagen is what keeps our skin from sagging, giving us that plump, youthful look," says dermatologist Dr. Ohara Aivaz.
Short answer: No. When it comes to collagen, there are many types. There are even different types of types! Dozens of types of collagen naturally occur in your body; there are various supplement forms, preparation types and even different sources.

In other words, the collagen peptides specifically trigger collagen production in joint tissues. So, unless you are consuming Type II undenatured or Matrix collagen specifically for joints, then the type(s) of collagen you ingest won't matter.
Initial results from collagen restoration treatments are usually visible immediately. However, new collagen growth can take anywhere from four to 12 weeks to complete.
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 ).
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.
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.
How long it takes for collagen supplements to work on skin/aging is about 12 weeks. A study found that participants experienced smoother skin texture (hydration, wrinkles, and skin elasticity) at six and 12 weeks, with more significant results appearing at the 12-week mark.
The skin responds the fastest to collagen supplementation, and to relatively low doses. 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.
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.

One key difference between collagen and collagen peptides is that one is a broken-down form of the other. Collagen peptides are made by breaking animal collagen down through hydrolysis. So, while collagen is a complete protein, collagen peptides are fragments of that protein.
Look for collagen that comes from grass-fed, pasture-raised animals or wild-caught fish. The collagen should not have any additional fillers or additives. Overall, when choosing a collagen supplement opt for a brand that is transparent about their processes and sourcing.
