Evaluating Moisturizers for Effective Scar Management

Recent research conducted by experts from the University of Adelaide and the Royal Adelaide Hospital has shed light on the varying effectiveness of different moisturizers in managing scars. Not all skincare products offer the same benefits when it comes to hydration and reducing water loss from the skin, which are crucial factors in scar healing and appearance.

Ph.D. candidate Tanja Klotz, an occupational therapist specializing in burns, investigated the impact of eight popular moisturizing products on skin hydration and transepidermal water loss (TEWL) within a scar model. Her study emphasizes the importance of choosing the right moisturizer to support the healing process, especially for individuals with active, linear, widespread, or keloid scars. The skin barrier's integrity plays a vital role in preventing dehydration and minimizing scar activity, which is compromised when the skin is damaged or exposed to harsh environmental conditions.

The research, published in the journal Burns, highlights notable differences among common products. For instance, silicone gel sheets, frequently used for scar treatment, effectively block TEWL but simultaneously cause high hydration levels that evaporate quickly after removal. On the other hand, a liquid silicone gel showed poor hydration benefits. Interestingly, Eucerin Advanced Repair Cream outperformed other products in maintaining skin hydration, likely due to its formulation containing glycerin and urea, which promote moisture retention.

The study also pointed out that higher prices do not necessarily translate to better performance in scar moisturization. Products like Alhydran, Strataderm, and BioOil, despite being costly, demonstrated limited ability to normalize TEWL and enhance hydration compared to more affordable options. This finding underscores the importance of evidence-based choices over cost assumptions.

In summary, the research advocates for clinicians and patients to carefully consider the specific properties of moisturizing products used in scar care. Choosing evidence-supported products can significantly influence the outcomes of scar management, promoting better hydration, reducing water loss, and potentially improving scar appearance over time.
