Botulinum toxin injected into specific muscles allows for the gradual relaxation of expression lines, with effects beginning at 3-5 days, an optimal result at 10-14 days, and a duration of efficacy of 3 to 6 months.

The mechanism of action described is scientifically accurate: botulinum toxin temporarily blocks the release of acetylcholine at the neuromuscular junction, thereby preventing muscle contraction (meta-analysis, Journal of Cosmetic Dermatology). The timelines for the onset of effects (beginning within a few days, peaking at two weeks) are widely validated by clinical literature and standard health authority protocols. The claim regarding the duration (3 to 6 months) is also supported by numerous observational studies and randomized clinical trials (RCT). The concept of 'prevention' before the onset of wrinkles is a common notion in aesthetics, although the definition of 'prevention' here is more cosmetic than clinical. It is important to note that the 'natural' look mentioned depends entirely on the injection technique and the dosage, which qualifies the idea of a systematically harmonious result. Finally, the term 'glow effect' is an aesthetic interpretation rather than a direct physiological benefit of the toxin, which acts on the muscle and not on the intrinsic quality of the skin.
