The body naturally produces collagen every day, however, bolstering these levels can take varying amounts of time based on which methods you’re utilizing. The initial results from collagen restoration treatments are often visible immediately and can last anywhere from 6-16 months. However, new collagen production and growth can take anywhere from 4-12 weeks. While many collagen-stimulating treatments are very effective at restoring and replacing diminished collagen stores, these results are only temporary and will require follow-up to keep levels topped up.
