The face changes at more than one layer
Cleveland Clinic describes age-related changes in collagen and elastin, thinning or loss of underlying fat and other structural changes. As elasticity declines, gravity contributes to loose tissue around the cheeks and jaw. The pattern differs among people, so a single ingredient cannot be presumed to correct every cause. [1]
A skin-study result does not demonstrate a jawline lift
Collagen trials may measure hydration or elasticity, with important study-quality limitations. Such outcomes do not establish reversal of displaced tissue or a clinically meaningful jowl lift. A photograph, short-term plumping or a general anti-aging claim is not equivalent to that evidence. [2]
Match the option to the actual concern
Imagine a product promises to eliminate jowls by supplying collagen. Ask what human study measured that result. A qualified clinician can assess whether the concern involves skin, volume or other structural changes and discuss realistic options. A supplement should not be sold as a guaranteed substitute for that assessment. [1][3]

| A related product or study | The same intervention |
| A plausible mechanism | A guaranteed result |
