Taking very high doses of vitamin B5 (pantothenic acid) could reduce excess sebum and improve acne, when coupled with a simplified and less frequent face-cleansing routine.
The community seems very positive and encouraging, converging on emotional support, although the 'megadosing' aspect is an individually reported experience. Scientifically, the idea that vitamin B5 regulates sebum is based on old and limited studies, such as the one by Lit-Hung Leung (1995), which suggested effects on sebum production at massive doses, but these results have never been confirmed by robust randomized clinical trials (RCTs). The use of benzoyl peroxide (2.5%) is, however, solidly supported by numerous meta-analyses as an effective first-line treatment for acne. Reducing the frequency of cleansing is a common practice in 'wellness' to preserve the skin barrier, which can effectively limit irritation, but this remains a subjective observational approach. In summary, if improvement is real, it is impossible to say whether it comes from vitamin B5, benzoyl peroxide, or simply from stopping an overly abrasive routine. Furthermore, very high doses of supplements without monitoring may present risks of interactions or side effects not documented here.

Taking a break from daily makeup wear could allow the skin to breathe better, restore its natural balance, and reduce visible imperfections.
The community largely agrees on the psychological and aesthetic benefits of this practice, reporting satisfaction linked to the simplification of their routine. From a scientific standpoint, the idea that skin 'breathes' is a misuse of language, as it does not possess lungs; however, stopping makeup can reduce pore obstruction (a comedogenic phenomenon) in sensitive individuals, as indicated by studies on non-comedogenic cosmetics (Journal of Clinical and Aesthetic Dermatology). The perceived improvement is often linked to the simultaneous adoption of a gentler skincare routine or the removal of ill-suited products, rather than the absence of makeup itself. There are no RCTs demonstrating that makeup inherently prevents skin health if cleansing is adequate. Conversely, the benefit is real regarding the reduction of potential mechanical or chemical irritation. The community converges positively toward this approach, although a minority emphasizes the importance of an appropriate cleansing routine to observe real results.

To optimize the healing of a cutaneous wound and limit residual scarring, it is preferable to favor a moist environment (rather than letting the wound air dry) by using occlusive agents or specific dressings, while consulting an expert for initial care.
The community strongly converges on the 'moist wound healing' method to avoid the formation of scabs, a consensus supported by research. According to systematic reviews (e.g., Cochrane Library), keeping a wound hydrated helps skin cells migrate more quickly, thereby reducing the risk of visible marks compared to air-exposed healing. The use of silicone (gel or dressings) for scar management once the wound has closed is also validated by meta-analyses as a reference strategy to prevent raised scarring. The idea that superficial abrasions do not systematically leave marks is confirmed by standard clinical observation, as the skin possesses a high capacity for natural regeneration. The use of occlusive ointments is prudent, but self-diagnosis remains risky; the systematic recommendation to consult a professional is therefore the most robust point of the thread. Advice regarding protein intake and hydration constitutes common-sense metabolic levers, although their direct impact on an isolated scratch is difficult to isolate from genetic factors.

The community notes, with humor and insistence, that sun protection should not be limited to the face but extended to the entire body to maintain a youthful appearance and prevent signs of overall skin aging.
The community converges on the idea that UV exposure is the primary factor in premature aging, which is strongly supported by research. Observational studies and reviews of dermatological literature widely confirm that ultraviolet radiation is responsible for the majority of visible changes in the skin over time (photoaging). Daily use of sunscreen is recognized by public health authorities as the most effective method to limit this damage. However, the thread confuses the causes somewhat, suggesting that the use of retinol or simple topical application could compensate for or cause systemic effects, which lacks scientific nuance. While protection is crucial, the idea that loss of hair density (mentioned by the author) is directly linked to a facial skincare routine or a lack of body sun protection remains without direct clinical evidence. The consensus here is a strong signal of the popularity of sun prevention, rather than a scientific validation of the link between facial routines and overall hair health.

Using an anti-dandruff shampoo containing ketoconazole as a facial cleanser is said to eliminate sebaceous filaments and fungal skin imperfections.
The community largely converges on the idea that this product, when used off-label for the face, is an effective tool against skin irregularities, although some note the risk of dryness. Scientifically, ketoconazole is a powerful antifungal recognized for treating seborrheic dermatitis, which is often linked to the proliferation of Malassezia yeast (source: Mayo Clinic, expert opinion/clinical practice). If imperfections are caused by this yeast, topical use can indeed improve the appearance of the skin. However, the idea that it reduces sebaceous filaments through a direct anti-androgenic action is an extrapolation not supported by solid clinical evidence in aesthetic dermatology. There are no robust studies validating the use of ketoconazole as a routine treatment for the overall management of skin oil or pores. The observed effect could also be related to the temporary drying of the skin, which makes pores less visible—an approach to be handled with caution to avoid altering the skin barrier.
