If you mean firming loose or sagging neck skin, there isn’t a proven cream or exercise that can rapidly tighten significantly loose skin. The fastest and cheapest approach depends on how much laxity you have.
Cheapest options
Daily sunscreen (SPF 30+) on the neck helps prevent further collagen breakdown from UV exposure.
A retinoid such as retinol may gradually improve skin texture and stimulate collagen. Results take months, not days.
Moisturizer can temporarily make the skin look smoother and less crepey.
Don’t smoke, since smoking accelerates collagen and elastin damage.
What about neck exercises?
Exercises can strengthen underlying muscles, but evidence that they substantially tighten loose neck skin is limited. They won’t remove excess skin.
Fastest noticeable results
For significant sagging, procedures such as ultrasound/radiofrequency skin tightening or a surgical neck lift can produce more noticeable changes. Non-surgical procedures vary considerably in effectiveness, cost, and suitability; a qualified dermatologist or plastic surgeon can determine what makes sense for your skin.
Be skeptical of “one-minute neck exercises,” creams that promise instant tightening, or DIY treatments. They generally cannot reproduce the results of removing or structurally tightening excess skin.
If you tell me your age and whether the problem is loose skin, a “turkey neck,” horizontal neck lines, or fat under the chin, I can suggest the most affordable options for that specific issue.
