Article Synopsis
- The skin acts as a protective layer for the body and plays a crucial role in how we interact with our environment, with a strong interest in understanding its function and aging effects.
- A study was conducted comparing touch perception between younger (20-28 years) and older women (65-75 years), looking into aspects like touch detection, skin hydration, and the effects of moisturizing cream.
- Results showed that older adults experienced drier skin and reduced touch ability on their fingers, but touching appreciation increased with age, highlighting the importance of long-term skin care for maintaining touch perception, especially on the hands.
Background: Vascular cognitive impairment and dementia results from blood components passing through disrupted blood brain barriers (BBBs). Current treatments can reduce further progress of neuronal damage but do not treat the primary cause. Instead, these treatments typically aim to temporarily disrupt the BBB.

- Dandruff is a persistent scalp condition that can be influenced by various environmental and personal factors, leading to changes in scalp health that may require treatment like Selenium disulfide (SeS2) shampoo.
- Research focused on how SeS2 shampoo affects dandruff severity, scalp microbiome, and sebum properties during treatment and after resuming normal conditions.
- The study found that SeS2 significantly reduced dandruff symptoms and harmful microbes in the scalp, improved the balance of beneficial bacteria, and enhanced the quality of scalp oils, showing good tolerance from users even after stopping treatment.
Article Synopsis
- Dandruff is a common scalp issue caused by various microbial and host-related factors, with Malassezia restricta yeast playing a significant role in its development.
- Recent studies identified squalene monohydroperoxide and malondialdehyde as biomarkers related to dandruff, indicating that sebum lipoperoxidation is important in dandruff's onset and persistence.
- The research suggests that Malassezia restricta contributes to sebum peroxidation, leading to skin barrier changes, and proposes that inhibiting these processes might offer a new way to treat dandruff.
