Questions and answers

What the research says

• Aluminum oxide crystal microdermabrasion resulted in mild subjective and clinical improvement, increased skin temperature, decreased sebum content, temporary increased roughness, decreased skin stiffness, increased skin compliance, and histological vascular changes in ten subjects with photodamaged skin compared to baseline measurements.

  Dermatologic Surgery, 2001

• A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2017

• Both sodium chloride and aluminum oxide microdermabrasion altered the epidermal barrier by significantly increasing transepidermal water loss and hydration at 24 hours in eight patients.

  Dermatologic Surgery, 2002

• Aluminum oxide microdermabrasion facial treatments in eleven volunteers resulted in clinical improvements in dyschromia, actinic changes, and fine rhytides, along with epidermal and dermal histological changes, compared to controls.

  The Journal of Dermatological Treatment, 2002

• Aluminum oxide crystal microdermabrasion resulted in good to excellent clinical improvement in 41 patients with facial scarring over a mean of 9.10 treatment sessions.

  Dermatologic Surgery, 1995

• The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.

  Journal of Cosmetic Dermatology, 2020

• Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.

  International Journal of Cosmetic Science, 2001

• Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.

  Journal of Drugs in Dermatology, 2012

• Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups.

  Military Medicine, 2024

• A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate.

  Skin Research and Technology, 2000

• Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms.

  Clinical and Experimental Dermatology, 2007

• Repeated application of concentrated water-in-oil emulsions over four weeks caused no skin irritation, positively affected skin properties, and delivered almost 50% of the applied fluorescein sodium, with isopropyl myristate showing superior penetration performance compared to liquid paraffin in healthy volunteers.

  International Journal of Pharmaceutics, 2019

• Topical application of an emollient emulsion containing 15.0% caprylic/capric triglyceride doubled the amount of urocanic acid isomers and increased skin hydration with reduced transepidermal water loss in healthy subjects, though it did not prevent ultraviolet-induced urocanic acid isomerization.

Why other exfoliants fit oily acne-prone skin better

• Chemical peels with 30% supramolecular salicylic acid effectively treated acne and reduced facial sebum secretion while improving skin hydration and barrier function in 25 patients.

  Journal of Cosmetic Dermatology, 2022

• Two percent supramolecular salicylic acid showed similar efficacy to 0.01% adapalene plus 5% benzoyl peroxide in reducing acne lesions in 31 patients over 28 days.

  Cutaneous and Ocular Toxicology, 2019

• Twice daily application of a multitargeted dermocosmetic cream provided comparable efficacy to benzoyl peroxide 5% gel in reducing inflammatory, non-inflammatory, and total lesions in 150 Caucasian subjects with mild-to-moderate acne over 56 days, while demonstrating superior skin tolerability.
