Marine sponge collagen: isolation, characterization and effects on the skin parameters surface-pH, moisture and sebum

2002

A previously described isolation procedure for collagen of the marine sponge Chondrosia reniformis Nardo was modified for scaling-up reasons yielding 30% of collagen (freeze-dried collagen in relation to freeze-dried sponge). Light microscope observations showed fibrous structures. Transmission electron microscopy studies proved the collagenous nature of this material: high magnifications showed the typical periodic banding-pattern of collagen fibres. However, the results of the amino acid analysis differed from most publications, presumably due to impurities that still were present. In agreement with earlier studies, sponge collagen was insoluble in dilute acid mediums and all solvents inv…

On cosmetically treated hair — aspects and pitfalls of interpretation

1997

Popular hair cosmetic treatments like bleaching or permanent waving were found to affect the stability of incorporated drugs and to cause alterations of the fibers at an ultrastructural level. This may result in a partial or complete loss of drug substances, depending on the particular drug molecule and on its concentration prior to the cosmetic treatment. Moreover, from literature, there is some evidence that drug molecules are not only incorporated into the growing fiber by passive diffusion from blood into the matrix cells and melanocytes, but that the substances enter the hair also via perspiration such as sweat and sebum. Since permed and bleached hair shows an enhanced sorption capaci…

A Split Face Comparative Study to Evaluate the Efficacy of 40% Pyruvic Acid vs. Microdermabrasion with 40% Pyruvic Acid on Biomechanical Skin Paramet…

2022

The synergy of cosmetic acids, with their keratolytic and antibacterial properties, with the mechanical exfoliation of the epidermis brings faster and better treatment results. The aim of the study was to compare the effects of using only pyruvic acid and the synergy of microdermabrasion and chemical exfoliation. In total, 14 women diagnosed with acne took part in the study. Two areas were marked on the participants’ faces: the right side (microdermabrasion treatment and a preparation containing pyruvic acid 40%) and the left side (preparation containing pyruvic acid 40%) without mechanical exfoliation. A series of four treatments was performed at 2-week intervals. Skin parameters such as s…

Efficacy of Oxybrasion in the Treatment of Acne Vulgaris: A Preliminary Report.

2022

There are many cosmetic methods to reduce skin eruptions in people with acne vulgaris. As oxybrasion is a safe method of exfoliating dead epidermis, our objective was to investigate its effectiveness in young women with acne vulgaris. The Global Acne Grading System (GAGS) and Derma Unit SSC 3 device (Sebumeter SM 815, Corneometer CM 825) were used to assess acne vulgaris and skin properties. Twenty-four women aged 19–21 years (M = 19.50, SD = 0.66) with diagnosed mild acne vulgaris and a high level of sebum (more than 100 μg/cm2) participated in the study. Women on any dermatological treatment within the last 12 months and/or hormonal contraception were excluded. Probands were randomly assi…

The effects of combined diamond microdermabrasion and a mixture of cosmetic acids on the condition of acne prone skin: a case report

2021

Background: Exfoliating treatments are widely used in cosmetology and dermatology forthe treatment of skin lesions and, above all, toreduce the number of skin eruptions that occur with acne vulgaris. An effective treatment that can be offered to people suffering from this disease is diamond microdermabrasion. The addition of acid peeling to this treatment may lead to even better results than in the case of monotherapy. Aim of the study: To assess the effectiveness of a combination of microdermabrasion and acid peeling on a 21-year-old woman suffering from acne vulgaris. Case report: The patient suffered from acne vulgaris, too high a level of sebum on the entire surface of the face, and, ov…

Acne and skin lesions that appear in its course deteriorate the quality of life of patients, cause depression and the emergence of suicidal thoughts. Cosmetic treatments can have a positive effect on improving skin condition by cleaning up skin eruptions, thus improving the well-being of affected people. Hydrogen purification is a treatment that uses alkaline water generated by a device, which reduces sebum from the surface of the epidermis. This is a novel treatment that has recently been introduced to beauty salons. On the other hand, cosmetic acids have been used for many years for treating people with acne vulgaris and give spectacular results in terms of improving the skin condition. I…

In Vitro and In Vivo Regulation of SRD5A mRNA Expression of Supercritical Carbon Dioxide Extract from Asparagus racemosus Willd. Root as Anti-Sebum a…

2022

Oily skin from overactive sebaceous glands affects self-confidence and personality. There is report of an association between steroid 5-alpha reductase gene (SRD5A) expression and facial sebum production. There is no study of the effect of Asparagus racemosus Willd. root extract on the regulation of SRD5A mRNA expression and anti-sebum efficacy. This study extracted A. racemosus using the supercritical carbon dioxide fluid technique with ethanol and investigated its biological compounds and activities. The A. racemosus root extract had a high content of polyphenolic compounds, including quercetin, naringenin, and p-coumaric acid, and DPPH scavenging activity comparable to that of the standa…

The effectiveness of green tea and sonophoresis on oily skin: a case report

2022

Background: Oily skin can be extremely problematic for sufferersand presents a great challenge for cosmetologists. This condition is characterized by an excessive amount of sebum on epidermal surface and enlarged skin pores.Modern cosmetology is able to offer a wide range of treatments that are able to reduce excess sebum secretion, and an appropriate diagnosis and cosmetic interview will allow for the selection of a suitable cosmetic treatment. If there are no contraindications for device treatments and the client is not allergic to cosmetic products, an ultrasound treatment called sonophoresis may be used. Green tea is obtained from both the leaves and buds of the Camellia sinensis plant.…
