As elasticity decreases, I'm looking for anti-aging treatments.

Lately, my skin doesn't look the same as it used to and feels like it's losing elasticity, so I'm looking into anti-aging treatments.

There are so many types of anti-aging treatments that I'm really confused about where to start.

Botox, fillers, lifting (such as Ulthera and Thermage), and lasers seem to be the most common treatments. What are the differences between them?
Is it correct that Botox is used to smooth wrinkles and fillers are for filling in sunken areas? Then, I am curious if lifting procedures are used to lift sagging skin.

I'm also curious about the price range for anti-aging treatments.

I heard that Botox is relatively inexpensive, but I heard that fillers and lifting procedures are very expensive.
I would also like to know what the average cost is and why there is such a large difference between hospitals.

I'm also worried about side effects.

I've heard stories about facial expressions looking awkward after getting Botox, and that fillers can cause side effects like clumping or migration. Are these actually common?
I am also wondering if there are any risks associated with lifting procedures, such as pain, swelling, or burns.

I also want to know who would benefit from receiving this.
I heard that the recommended procedures differ for people in their 30s compared to those in their 40s and 50s, so I am curious to know which procedures have high satisfaction rates for each age group.

Finally, based on those who have actually tried it.
If you had to recommend just one anti-aging treatment that offers great value and high satisfaction, which one would you choose the most?

Cost-effectiveness is important ^^
