Best firming/tightening products?

I'm currently trying to figure out which skincare to purchase during the Black Friday sales and would like some recommendations to help me decide since you all always have great suggestions and help me stay informed of brands I didn't know about.

I'm mostly interested in firming and tightening products. I just turned 30 so I'd like to focus on firming and tightening of the facial skin at this time. Are there any particular brands or products that would be good for these concerns or specific ingredients I should look for? I've considered Skinceuticals P-Tiox, HA Intensifier, SkinBetter Interfuse Lines, and the Droplette 2 device, but would love to hear more experiences or other recommendations.
