Abstract

Ultraviolet B (UVB) exposure is a major cause of skin aging, leading to collagen degradation and wrinkles due to free radical damage. Stevia (Stevia rebaudiana Bertoni) has antioxidant properties that may counteract this by preserving Transforming Growth Factor-β1 (TGF-β1), essential for collagen synthesis. This study evaluated the effects of stevia leaf extract cream on TGF-β1 and collagen levels in male Wistar rats. Thirty rats were divided into five groups: K0 (no UVB, no cream), K1 (base cream), P1 (2.5% stevia cream), P2 (5% stevia cream), and P3 (10% stevia cream). Groups K1, P1, P2, and P3 were exposed to a cumulative UVB exposure of 840 mJ/cm2 over four weeks. The TGF-β1 levels measured by ELISA did not differ significantly among groups (p>0.05). However, collagen levels, assessed using Picro Sirius Red staining, varied significantly (p<0.05). The K1 exhibited significantly lower collagen compared to K0 (p=0.003), whereas the P2 group effectively prevented collagen degradation compared to K1 (K1: 65.87% vs. P2: 77.92%; p = 0.005). While stevia leaf extract cream did not prevent TGF-β1 reduction, it demonstrated a clear protective effect against UVB-induced collagen loss. Among the tested concentrations, 5% stevia leaf extract cream was the most effective in preserving dermal Collagen, highlighting its potential as a topical agent for preventing photoaging and maintaining skin structural integrity.

Abstract

Introduction: Maintained skin moisture is an indication of healthy skin. Acute UV exposure can cause sunburn, which is characterized by a loss of moisture in the skin. Polyphenol compounds are one practical approach to protecting the skin from sunburn so that skin moisture is maintained. Blueberries are one of the natural ingredients consists of anthocyanin compounds, which are polyphenols from the flavonoid group. Aims: To determine the effect of blueberries on skin moisture exposed to acute ultraviolet rays. Methods: Literature study using references in the form of research articles and literature reviews from national and international journals and related books published in the last 10 years. In writing this literature review, 42 references were used which were accessed through Google Scholar, NCBI, Crossref, and Pubmed. Results: Blueberries anthocyanins can maintain skin moisture from increased transepidermal water loss (TEWL) due to acute UV ray exposure by reducing the formation of UV stimulated reactive oxygen species (ROS) and lipid peroxidation in keratinocyte cells to maintain the elastic modulus and mechanical properties of keratinocytes as well as can prevent sunburn by reducing the skin's modulation of UV exposure. However, the absorption of anthocyanin compounds in the intestine is so low that taking blueberries orally alone is not enough to achieve good biodistribution. Conclusion: Blueberries affect retaining moisture in skin exposed to acute UV rays, so they have the potential to be used as skincare ingredients. However, further research needs to be done, especially to determine the side effects that can be caused and the required extract concentration.
