Hydradermabrasion: an innovative modality for nonablative facial rejuvenation

Hydradermabrasion through the lens of Line-Field Confocal Optical Coherence Tomography

BACKGROUND

Hydradermabrasion, also known as "HydraFacial," is an exfoliative cosmetic procedure for skin rejuvenation that has gained popularity. Despite its increasing popularity, clinical studies validating its efficacy with non-invasive assessment of histological changes to the skin, are scarce. In this study, we used Line-Field Confocal Optical Coherence Tomography (LC-OCT), an optical imaging device, to non-invasively visualize microscopic changes to skin anatomy after hydradermabrasion treatment.

MATERIALS/METHODS

Eight volunteers (Fitzpatrick skin types II-V) were recruited for this study. Images, using LC-OCT (DeepLive, DAMAE medical) were obtained before and after hydradermabrasion and at 2 weeks post-treatment. A commercially available hydradermabrasion device was utilized to perform the dermabrasion.

RESULTS

In the epidermis, initially, a decrease in the average thickness of the stratum corneum, from 9.42 to 6.67 µm was visualized in LC-OCT images after hydradermabrasion. However, at 2 weeks of follow-up, the average stratum corneum thickness was 9.75 µm, resulting in an overall increase in the average thickness after treatment. Improved homogenization of the stratum corneum and decreased number of undulations in the epidermis post-treatment were also visualized. In all the subjects, the superficial dermis appeared stretched, which returned to baseline by the 2-week follow-up. At the 2-week follow-up, there were no visible differences in the quality and quantity of collagen fibers in the dermis.

CONCLUSION

In our study, LC-OCT images of the epidermis and dermis demonstrated microscopic features of skin rejuvenation when treated with hydradermabrasion. Thus, not only highlighting the efficacy of hydradermabrasion but also the potential of LC-OCT to serve as a tool for visualizing the microscopic effects of cosmetic procedures on skin anatomy.

Combining Diamond-Tip Dermabrasion Treatments and Topical Skincare in Participants with Dry, Hyperpigmented, Photodamaged or Acne-Prone/Oily Facial Skin: A Clinical Usage Study

Purpose

An in-office diamond tip microdermabrasion device (DG) was designed to simultaneously exfoliate, extract, and infuse topical cosmetic serums into the skin to improve its appearance. Combining in-office procedures with take-home skincare may enhance treatment outcomes. This study aimed to assess the efficacy of a novel combination of DG treatments with a take-home cosmetic skincare regimen (DGR) to address facial dryness, hyperpigmentation, photodamage, or acne-prone/oily skin.

Patients and Methods

In this 12-week, open-label, single-center study, participants were assigned to 1 of 4 groups according to skin presentation: dry, hyperpigmented, photodamaged, or acne-prone/oily. All participants received 6 bi-weekly DG treatments with tailored DGR topical products. During the DG treatment, the dry, hyperpigmented, photodamaged, and acne-prone/oily groups received hydrating, brightening, antioxidant, and pore-clarifying serums, respectively. Study endpoints included investigator grading, standardized photography, and participant questionnaires.

Results

Sixteen participants aged 22 to 70 years with Fitzpatrick Skin Types I-V completed the study. Immediately after the first DG treatment, significant improvements in dryness, radiance, texture, photodamage, and fine lines were achieved (P<0.01). At 72 hours, significant improvements were maintained in all these parameters except fine lines (P<0.05). The DG and DGR combination provided significant long-term improvements at week 12 compared to baseline for dryness, radiance, texture, hyperpigmentation, photodamage, skin tone unevenness, and periocular/perioral fine lines (P<0.05).

Conclusion

The combination of DG and DGR showed significant immediate and long-term improvements in skin appearance. These results show that the DG and DGR combination is a well-tolerated and effective intervention to enhance different aspects of facial skin quality.

Acne vulgaris and the most popular and new cosmetological treatments

INTRODUCTION

Acne vulgaris is a disease that has an enormous impact on appearance of the skin of the patients and also on their quality of life. Long-term dermatological treatment, which often lasts years, and disease relapses contribute to the occurrence of low self-esteem and depression. Acne is one of the 10 most common diseases in the world and the most common inflammatory skin disease. Many methods of dermatological treatment that bring very good results are available. However, educating people with acne on how to take care of their skin on a daily basis to minimize the bleak effects of the disease is an extremely important element. Contemporary cosmetology creates an environment for not only taking care of the skin at home, but also develops in-office treatments with exfoliation of the dead epidermis as an extremely important and priority part of treatment. The cosmetologist can propose both chemical and apparatus methods, which are selected individually for each client.

OBJECTIVE

The objective of this article is to provide information about cosmetological treatment used in acne vulgaris.

METHODS

In this article, we reviewed the published literature, article published in peer-reviewed journals.

RESULTS

There are many methods that work well in the case of acne skin care, more and more new treatments appear on the cosmetological market.

CONCLUSION

Acne skin care in beauty parlor is very important element.

Cosmetic devices based on active transdermal technologies

Active transdermal technology, commonly associated with drug delivery, has been used in recent years by the cosmetic industry for the aesthetic restoration of skin and delivery of cosmetic agents. In this article, we provide an overview of the skin's structure, various skin types, skin's self-repair mechanisms that are stimulated from the usage of cosmetic devices and discuss cosmetic applications. Summaries of the most common active transdermal technologies such as microneedles, iontophoresis, sonophoresis, lasers and microdermabrasion will be provided, in relation to the marketed cosmetic devices available that incorporate these technologies. Lastly, we cover combinations of active technologies that allow for more enhanced cosmetic results, and the current limitations of cosmetic devices.

The effect of physically applied alpha hydroxyl acids on the skin pore and comedone

OBJECTIVE

Alpha hydroxy acids (AHA) have been recognized as commonly used therapy for acne. Our studies examined whether an additional effect of physical treatment using chemical peeling combined with negative pressure and compared with AHA treatment only occurs in acne-prone subjects.

METHODS

The chemical peeling agent used 4% of an AHA solution (mixture of 1000 mL of carbonated water, 20 mL of glycolic acid and 20 mL of lactic acid). All subjects' faces were randomly divided into test and control groups. The test group was treated with chemical peeling combined with a physical effect, and the control group applied chemical peeling alone. For the 23 healthy females (average age: 30.17 ± 5.06 year), we measured sebum output level by light transmission, pore area and number by optical image analyser, and comedone counting before treatment and at 1, 2 and 4 weeks after a single treatment.

RESULTS

Compared to the before treatment, whiteheads and blackheads were significantly decreased at 1, 2 and 4 weeks in the test group (P < 0.05), but for the control group, whiteheads and blackheads showed a tendency to decrease at 1, 2 and 4 weeks. Also at 1 week, whiteheads and blackheads of the test group significantly decreased compared to the control group (P < 0.05). Pore area and number significantly decreased at 1 week (P < 0.05), and the sebum output level was significantly decreased at 4 weeks (P < 0.05) only in the test group, which did not show any significant group difference for individual parameters.

CONCLUSION

4% AHA solution combined with a physical effect had rapidly improving effects on whiteheads and blackheads synergistically. Combined physical therapy may have more impact on pore size and seborrhoea.

Topical polyphenolic antioxidants reduce the adverse effects of intense pulsed light therapy

BACKGROUND

Intense pulsed light therapy (IPL) has been associated with erythema and increased lipid peroxidation. Polyphenolic antioxidants have been shown to decrease inflammation and reduce oxidative stress in irradiated skin.

OBJECTIVE

To determine whether the topical application of polyphenolic antioxidants to IPL-treated skin reduced the adverse effects of IPL exposure.

METHODS

In a split-face study, 10 volunteers underwent three full-face IPL treatments (16 J/cm(2), 10 ms, 560 nm filter) spaced 3 weeks apart. A polyphenolic antioxidant solution was pneumatically applied to the left side of the face, beginning immediately before the first IPL treatment then weekly for six treatments. The lipid peroxide concentration, skin antioxidant level and skin moisture content were obtained before and after the study.

RESULTS

Skin treated with IPL alone contained a significantly higher concentration of lipid peroxides when compared to skin treated with IPL plus polyphenolic antioxidants (p<0.05). Skin treated with IPL alone contained a significantly lower level of polyphenolic antioxidants and had a significantly lower moisture content (p<0.05).

CONCLUSIONS

In this study, the concurrent pneumatic topical application of polyphenolic antioxidants reduced lipid peroxidation and skin dehydration in IPL-treated skin. Polyphenolic antioxidants may confer a protective effect on facial skin and enhance the effects of IPL therapy.
