Adolescents' self perceived acne-related beliefs: from myth to science

Sun exposure, a relevant exposome factor in acne patients and how photoprotection can improve outcomes

BACKGROUND

Acne pathophysiology includes a complex interaction among inflammatory mediators, hyperseborrhea, alteration of keratinization and follicular colonization by Propionibacterium acnes.

AIMS

To describe the impact of the exposome on acne and how photoprotection can improve outcomes.

METHODS

A narrative review of the literature was carried out; searches with Google Scholar and Pubmed from January 1992 to November 2022 were performed. The keywords used were "acne," "sunscreens," "photoprotection," "cosmetics," "cosmeceuticals," "pathogenesis," "etiology," "exposome," "sunlight," "stress," "lack of sleep," "diet," "postinflammatory hyperpigmentation," "pollution," "exposome," "ultraviolet radiation," and "visible light."

RESULTS

Environmental factors such as solar radiation, air pollution, tobacco consumption, psychological stress, diverse microorganisms, nutrition, among others, can trigger or worsen acne. Solar radiation can temporarily improve lesions. However, it can induce proinflammatory and profibrotic responses, and produce post-inflammatory hyperpigmentation and/or post-inflammatory erythema. While photoprotection is widely recommended to acne patients, only four relevant studies were found. Sunscreens can significantly improve symptomatology or enhance treatment and can prevent post-inflammatory hyperpigmentation. Furthermore, they can provide camouflage and improve quality of life. Based on acne pathogenesis, optimal sunscreens should have emollient, antioxidant and sebum controlling properties.

CONCLUSIONS

The exposome and solar radiation can trigger or worsen acne. UV light can induce post-inflammatory hyperpigmentation/erythema, and can initiate flares. The use of specifically formulated sunscreens could enhance adherence to topical or systemic therapy, camouflage lesions (tinted sunscreens), decrease inflammation, and reduce the incidence of post-inflammatory hyperpigmentation/erythema.

Perspectives and knowledge of acne vulgaris among young adolescents

Acne occurs in up to 90% of young adolescents, but prior research has found that this population exhibits a limited understanding of acne and is vulnerable to myths and misinformation accumulated from family members, friends, and social media. We created a virtual presentation on skin hygiene, acne prevention, and acne-associated stigma for adolescent youth (aged 9-13) to improve acne health literacy, which was reviewed by three board-certified dermatologists. A descriptive cross-sectional study using data collected for quality improvement (n = 209, total) revealed that approximately half (n = 102/202, 50.5%) of all students believed that acne could not be treated with medications, only 34.0% (n = 67/197) believed acne could impact their mental health, and most students incorrectly believed that dirt buildup (n = 124/209, 59.3%) and poor hygiene (n = 125/209, 59.8%) were pathogenic for acne. Our results stress the necessity of early evidence-based educational interventions as a cornerstone to breaking self-perpetuating myths and misinformation that may lead to acne mismanagement, delayed access to healthcare, and permanent scarring later in life.

The influence of cosmetics dedicated to oily and acne-prone skin on skin parameters

INTRODUCTION

Patient compliance with care recommendations is closely related to the role of cosmetics in delaying or preventing the side effects of medications used to treat acne.

METHODS

A total of 33 volunteers with symptoms of acne vulgaris were qualified for the study. The skin parameters were measured before the experiment, after the 4 and at the 8 weeks of use. The measurements were subject to moisturizing the skin and secretion of sebum and skin color. A skin acoustic parameters using high-frequency ultrasound (33 MHz) was also performed. The recorded images were used to determine the epidermal entrance echo thickness and echo density of dermis.

RESULTS

The results show a change in the value of skin parameters during the 8-week application of a specific skin care procedure. The secretion of sebum did not change significantly, there was a decrease in hydration, and the level of melanin and hemoglobin remained at the same level. The thickness of the epidermis entrance echo in the ultrasound image was thinned.

CONCLUSION

For many mild/moderate acne patients, cosmetics proven to be effective and well tested in clinical trials can offer a real benefit in reducing both inflammation, sebum production, melanin, and irritation, but should also be moisturizing.

Cognitive, emotional, physical, and behavioral stress-related symptoms and coping strategies among university students during the third wave of COVID-19 pandemic

Background

Stress is manifested by different physical, cognitive, emotional, and behavioral stress-related symptoms, and everyone experiences it uniquely. The COVID-19 Pandemic has tremendously affected university students' lives. So, we conducted this study to determine the stress frequency, causes, determinants, and related symptoms involving physical, cognitive, emotional, and behavioral traits and coping strategies among university students in Egypt during the third wave of the COVID-19 pandemic, 2021.

Methods

Cross-sectional study targeted 1,467 randomly selected undergraduate university students, representing all colleges from 30 universities in Egypt, through a validated self-administrated questionnaire.

Results

The total stress-related symptom score was statistically significant (p < 0.05), higher among females, married, living on campus, with a (B) GPA, and those who had both organic and psychological disorders. The top 10 prevalent physical symptoms were headaches, chronic fatigue, hair loss, low back pain, neck pain, shoulders and arm pain, ophthalmological symptoms, acne, shakiness of extremities, and palpitations, respectively. The most reported symptoms regarding the cognitive, emotional, and behavioral aspects were anxiety and racing thoughts, moodiness and irritability, and excessive sleeping, respectively. Nine hundred and thirty-seven (63.9%) reported that the COVID-19 pandemic badly affected their lives, either directly or indirectly. The study showed that the prevalence of stress among university students is more than 97%. One thousand and five (68.5%) preferred isolation as a relieving technique.

Conclusion

Stress and its related physical, cognitive, emotional, and behavioral symptoms are prevalent among university students. Most of the university students who were recruited reported that the COVID-19 pandemic badly affected their lives and used negative ways to deal with stress, like staying alone and sleeping too much. Positive ways to deal with stress, like seeing a therapist or meditating, were less common.

Association of Acne with Face Mask in Healthcare Workers Amidst the COVID-19 Outbreak in Karachi, Pakistan

Background

In the wake of coronavirus (COVID-19) global alert, people have begun to practice safety measures in order to reduce the exposure to life-threatening disease. The largest at risk population is undoubtedly the frontline healthcare workers (HCWs) who are using personal protective equipment (PPE), essentially face masks, to battle against this deadly virus. This study was conducted with the prime intention to reveal an association between face mask and acne and measure the prevalence of acne amongst HCWs amidst COVID-19 outbreak in Karachi. Furthermore, this study aimed to identify the type of mask generating acne, locate the common sites, assess the severity and establish an association of mask use with the skin type.

Methods

This cross-sectional study was carried out at Medicare Cardiac and General Hospital, Jinnah Medical College Hospital, Jinnah Postgraduate Medical Centre and Jamal Noor Hospital located in Karachi, Pakistan. A total of 348 HCWs were interviewed, of which only 193 met the inclusion criteria. All information was recorded on a predesigned proforma and analyzed using SPSS 25.0.

Results

Among 193 participants, acne was prevalent in 103 (53.4%) participants with maximum cases reported in female HCWs, and in doctors (p<0.05). Out of 73 HCWs using N-95 masks, 46 (44.7%) developed acne, with a p-value of 0.036. Skin type and past history of acne also yielded statistically significant results. Among all the skin types, HCWs with oily skin (64, 62.1%) were prone to face resurgence of acne or new-onset acne. The most common sites of eruption of acne were along the cheeks (45.1%) followed by the nose (40.9%). Majority of the population suffered from mild acne. Moderate and severe acne eruption was particularly observed in those wearing N-95 and surgical masks.

Conclusion

The use of face masks is associated with high rates of acne eruption. Disseminating the guidelines and indications of World Health Organization (WHO) regarding proper use of mask, encouraging awareness among HCWs and following proper doffing and donning protocol as endorsed by Centers for Disease Control and Prevention (CDC) will possibly minimize the adverse reactions.

Adolescents' beliefs and perceptions of acne vulgaris: A cross-sectional study in Montenegrin schoolchildren

Background

Acne is a common chronic inflammatory skin disease with a high prevalence in adolescent and early adult years. The aim of this study was to assess the self-perceived beliefs of Montenegrin secondary school pupils regarding the acne aggravating and ameliorating factors.

Methods

This cross-sectional survey of the pupils was conducted during October and November 2020 in four randomly selected public secondary schools in Podgorica, Montenegro. All 500 pupils were asked to fill in a questionnaire that included questions on age, sex, presence of acne, perceived acne aggravating and ameliorating factors, and sources of their information about acne.

Results

A total of 500 pupils, 234 (46.8%) boys, and 266 (53.2%) girls, aged 14−17 years, participated in the study. Acne was self-reported in 249 (49.8%) pupils, whereas 251 (50.2%) did not report acne. Factors most often believed to aggravate acne were inadequate face washing (85.0%), hormones (84.0%), sweets (82.0%), greasy food (72.6%), makeup (71.2%), and stress (67.8%). Overall the most prevalent acne ameliorating factors were cosmetic treatment (80.4%), increased water consumption (77.6%), a diet change to a healthier food choice (77.4%), and being on school holidays (62.2%). Girls reported more frequently that genetics, stress, sweets consumption, inadequate face wash, and makeup are acne exacerbating factors, whilst cosmetic treatment, increased water consumption, smoking, and being on school holidays are acne ameliorating factors. Boys more frequently considered the benefit of losing weight. There was no statistically significant difference between pupils with and without acne in perceived factors, except for cosmetic treatment. Those with acne more frequently believed in the benefits of cosmetic treatment.

Conclusions

Many adolescents’ self-perceived beliefs about factors that aggravate and ameliorate acne are myths and misconceptions without evidence-based justification. More efforts are needed to educate pupils about the acne aggravating and ameliorating factors, its health-related consequences, and the treatment possibilities.

An increase in normetanephrine in hair follicles of acne lesions through the sympatho-adrenal medullary system in acne patients with anxiety

Acne vulgaris, a chronic inflammatory skin disease, has been associated with not only sebaceous gland dysfunction but also various endogenous and exogenous stresses. Since sebaceous glands are under neuroendocrine control, including the hypothalamic-pituitary-adrenal axis and neuro-autocrine mechanisms, it remains unclear how psychological stress relates to the pathogenesis of acne. In this study, we investigated the relationship between psychological stress and catecholamine in acne lesions from 18 patients with mild or moderate acne. The State-Trait Anxiety Inventory (STAI) revealed that all patients were anxious, with six having low anxiety and 12 high anxiety. Salivary α-amylase activity (sAA), which is regulated by the sympatho-adrenal medullary (SAM) system, positively correlated with the STAI State Anxiety scores (STAI-S) and was significantly detectable in acne patients with high rather than low anxiety. In addition, the level of normetanephrine, but not metanephrine, both of which are catecholamine metabolites, in hair follicles of acne lesions also positively correlated with the STAI-S. Furthermore, the normetanephrine level was higher in patients with high rather than low anxiety, whereas there was no change in metanephrine in the hair follicles of the acne lesions. Moreover, neither the sAA nor metanephrine and normetanephrine in the acne lesions was related to acne severity in the patients. Thus, these results provide novel evidence that a SAM system-associated increase of normetanephrine level in hair follicles is involved in the acne pathology of patients with anxiety.

Diet and acne: review of the evidence from 2009 to 2020

BACKGROUND

Dietary habits may play a non-negligible role in the development, duration, and severity of acne, as shown in past critical review articles on such association.

METHODS

The aim of this systematic review is to supplement data available on scientific literature spanning the last 10 years by inserting the keywords "acne" or "acne vulgaris" and "diet", "nutrition", "food", "chocolate", "dairy", "whey protein", "fatty acid", or "drink" in the timeframe "January 2009-April 2020" within the PubMed database.

RESULTS

Fifty-three reviewed articles met eligibility criteria. They included 11 interventional clinical trials (seven randomized controlled trials and four uncontrolled open label studies) and 42 observational studies (17 case-control and 22 cross-sectional studies, and three descriptive studies).

CONCLUSIONS

This review reinforces the notion of a rapidly growing exponential trend of interest in this subject by the scientific community. Acne-promoting factors include high GI/GL food, dairy products, fat food, and chocolate, whereas acne-protective factors include fatty acids, fruit, and vegetable intake. The role played by specific dietary components pertaining to different foods, as done for milk (full-fat/whole, reduced-fat, low-fat/skim milk), dairy products (milk cream, ice cream, yogurt, cheese, etc.), or chocolate (cocoa, dark/milk chocolate), remains an unsolved issue and objective of future research.

Psychodermatology of acne: Psychological aspects and effects of acne vulgaris

INTRODUCTION

Acne is a chronic inflammatory skin condition seen commonly in adolescence and young adulthood. Despite being a frequent and nonthreatening life condition, acne has a significant psychological impact and comorbidity.

AIMS

This review will describe prevalence, common clinical features, different clinical presentations, differential diagnoses, and treatment recommendation. Special focus has been put on psychological aspects.

METHODS

We conducted a literature search on PubMed from January 2001 to June 2020 with the search terms of Acne vulgaris, psychological, adolescents, anxiety, suicide, mood disorders. Reference lists of identified articles were examined for further relevant studies. The search was limited to English language articles. No specified quality criteria were used for study inclusion.

RESULTS

The clinical manifestations of acne are very important in the differential diagnosis and its psychological implications.

CONCLUSION

Through this article, we conclude that despite being a frequent and nonthreatening life condition, acne has a significant psychological impact which requires effective treatment to improve the patient's skin and self-esteem.
