When dynamic wrinkles (wrinkles that are caused by muscle movement - horizontal forehead lines, frown lines, crow's feet) first start to form, they can be prevented early with botox injections. However, the longer you leave them, the deeper they get, and eventually the wrinkles can become scar-like and stay permanently even when you're not making any facial expressions - at this point, not even botox can help.
The skin starts to lose its moisture and form wrinkles normally starting from your thirties or forties; this is the optimal time for you to start botox injections.
Keep in mind that even the most expensive eye creams cannot erase the wrinkles that form when you laugh.
Here are the before and after photos of a real patient at Renewme Skin Clinic:
As you can see, this patient (male in his thirties) looks at least ten years younger without the crow's feet! If you look closely, he still has some fine lines around the corners when he smiles; this is because botox should be done naturally and just enough to prevent the severe wrinkles. Otherwise, your expression might look frozen and quite strange until the effects wear off.
Gosh, even his skin looks much healthier with all the lines gone!
