Does the collagen booster last a long time?

Every time I look in the mirror, I feel like my skin isn't as elastic as it used to be, so I've recently been looking into skin booster treatments. In particular, my skin looks tired quickly after smiling, and even when I apply makeup, it feels like the glow isn't coming through, so I really feel the need for skincare. That led me to read reviews of collagen boosters, and many people mentioned high satisfaction because of the feeling of plumping up from deep within the skin. I am interested in collagen boosters because I want a natural improvement in skin condition rather than an overly voluminous look. However, I am most curious about how long the effects of a collagen booster last. I would like to know if I can feel a difference after just one treatment, or if I need to receive the treatment consistently over several sessions to maintain the results.
