My advice is to be patient with the progress. Collagen and elastin production takes weeks and typically months.
I also recommend a healthy diet with lots of exercise. Why exercise? It forces the blood throughout your arteries,veins, and capillaries and allows the growth factors, hormones, vitamins, etc., to spread where they are needed.
Supplements such as zinc and topical vitamin c are also important to the production of collagen and elastin.
Consider needling if you are not already doing it. I also found that the chemical peels that I did also jump started the collage production. I knew that I was making major progress when my dermatologist and his nurse complimented me on my youthful looking skin.
Finally, wear sunscreen everyday to protect your skin. The collagen remodeling process is one that does not occur overnight, but takes months to complete. The wait is worth it.
