I am in agreement with Dr Israr. If you are looking to reduce laugh lines and cheek plumpness, you will need fillers. Or augment it with other treatments like threadlift, lasers.
To your second question, the effects of skin boosters and Rejuran are different.
Skin boosters work by being injected and help in drawing moisture from deep within, and from topical sources as they are hydrophilic (water loving). This helps to improve the hydration status, and explains why it is very popular in colder cities like Shanghai and Beijing.
Rejuran however works by augmenting skin healing and reducing skin sensitivity. Some doctors feel that there is an improvement of conditions like eczema and pigmentation. It does not per se improve the hydration status.
A combination of both therapies would yield great results. Do consider that.
