Asian women are usually more careful about sun protection, and they have the protection of pigment. Thickness of the skin and well-preserved skin quality exempt most from the need for biostimulation, especially with body skin. Poly-L-lactic acid (PLLA) in Asians is indicated for shape and contour rather than for skin enhancement. Roundness and smoothness of the face are pursued in a different pattern compared to their Caucasian counterpart. Forehead works for Asians have become a trend and are important indeed for the profile and the entire facial harmony. The requirement in the Asian forehead is more for shape, since common techniques for fullness leave it looking insufficient.
Optimizing Aesthetic Combination Treatments with Botulinum Toxin
Published in Yates Yen-Yu Chao, Optimizing Aesthetic Toxin Results, 2022
More and more treatments emphasize biostimulation by means of foreign body tissue disruption, immune reaction, or low-grade tissue injury to achieve more self-tissue production. These components of tissue reaction include cytokines, inflammatory cells, collagen, elastin, vessels, and intercellular matrix. It has to be carefully observed if these stimuli from chemical substances, tissue damage, and foreign bodies lead to immune reaction through adjuvant protein aggregate, nucleic acid, and cell debris recognition or foreign antigen presentation when the pharmaceutical protein of botulinum toxin is administered concomitantly. As practice patterns become more diversified and toxin use is in the majority off-label, it looks as if the parameters indicated for this toxin molecule have become less restrictive. Toxins are being blended with various injectable materials as a cocktail ingredient. Similar behaviors have been claimed to be novel by mixing the toxin with autologous fat, PRP, and mixtures of mesotherapy. Though the cells and tissues are autologous, there are multiple punctures involved in meso-like treatments, and the processed tissues carry dead cells, tissue debris, contaminants, and pathogens.

Three to four sessions of PLLA are recommended, 4–6 weeks apart (32), according to the patient’s needs. For CaHA biostimulation/skin tightening, two to three sessions are usually recommended, 1–2 months apart (44). Once treatment is completed, annual reinjections may be necessary.

The clinical success of DO is highly dependent on the condition of the bone microstructure. In situations such as osteoporosis, osteopenia and diabetes mellitus [12], which cause deterioration of bone microstructure, bone healing may cause some complications. Osteoporosis is a systemic disease in which the bone formation-resorption cycle and balance is disrupted in favor of destruction. In this disease, antiresorptive drugs (bisphosphonate-denosumab) and anabolic drugs (teriparatide) are used to prevent spontaneous bone loss [13]. However, the use of these drugs gradually decreasing because of insensitivity or tolerance and their serious side effects [14]. Biostimulation techniques such as ESWT, low-intensity ultrasound therapy, recombinant bone morphogenetic factors, low-level laser therapy, are methods is recommended to avoid complications in bone healing so that treatments can be successful [15–17]. Our study aim was to induce callus production and mineralization using ESWT in the osteoporotic experimental model, and as a result, accelerate maturation, improve its biomechanical properties, and shorten the consolidation process. Our study is the first to examine the effect of ESWT on the callus formation obtained in DO in osteoporotic subjects. The fact that all distractions occurred as planned and there were no cases of early ossification in any of the subjects in our study shows that the distraction protocol was successful. However, the lower bone density observed in the ovariectomized control group compared to the healthy control group indicates that the osteoporotic model was successfully implemented.
Assessing the impact of low level laser therapy (LLLT) on biological systems: a review

Low-level laser irradiation has been used in clinical practice causing biostimulation. A number of diseases and physical conditions are mentioned to respond to laser therapy (photobiostimulation) (Basso et al. 2013). At the cellular and molecular level, there is still significant argument regarding the effectiveness of lasers in producing the desired practical responses (Basso et al. 2013). To illustrate the therapeutic effects, through optical stimulation processes, we introduce here briefly the available light sources and their potential to interact at the cellular and molecular level. Currently, these are not well supported by the literature.

Considering estrogen therapy compared to HA, we identified studies which found a global similar effect [24], studies which found a greater effect for estrogen therapy [19,23] and studies which found a greater effect on HA administration. Interestingly, although VVA pathology relies mainly on a lack of estrogens [7], HA administration seems to be promising as a valid alternative with similar efficacy. Indeed, HA action is not limited to a moisturizing action. Intriguingly, HA administration seems to also have biostimulation properties [52] and this could lead to a different therapeutic approach.
