Scientific Effects of Collagen on Skin Health and the Aging Process
Recent scientific studies provide better insights into the effects of active ingredients on collagen synthesis. Collagen is one of the fundamental building blocks of skin health, providing elasticity and firmness. As the skin ages, collagen production decreases, leading to an increase in wrinkles and sagging. It has been proven that active ingredients, especially Vitamin C, peptides, and hyaluronic acid, increase collagen production and delay signs of aging.
These ingredients found in skincare products support the natural structure of the skin, strengthen the skin barrier, and make it more resistant to external factors. These findings, based on scientific data, enable users to make conscious choices in skincare, achieving a healthier and more youthful skin appearance. Choosing active ingredients that support collagen production is crucial to enhance the effectiveness of skincare routines.
According to the 2018 study published by Anna Czajka and her team, daily collagen peptide supplementation, combined with vitamins and other bioactive components, has positive effects on improving skin elasticity and supporting joint health.
The study involves a double-blind, randomized, placebo-controlled clinical trial. The results showed a significant increase in skin elasticity and improvements in joint health for participants taking daily oral collagen peptide supplementation. These findings offer an effective solution to help slow down the signs of aging (Czajka and Team, 2018).

According to the 2022 study published by Jemin Kim and his team, oral supplementation with low-molecular-weight collagen peptides has shown positive effects in reducing skin wrinkles and improving the biophysical properties of the skin. The study suggests that it may provide anti-aging effects by restoring extracellular matrix proteins damaged by photoaging.
The study observed that oral supplementation with low-molecular-weight collagen peptides improved wrinkles, elasticity, moisture balance, and barrier integrity in photoaged facial skin (Kim and Team, 2022).

The 2022 systematic review and meta-analysis study published by Qian Sun and his team evaluated the effectiveness of different dietary supplements for skin hydration in healthy adults. The study found that oral supplements like collagen, ceramide, hyaluronan, and procyanidin are effective in skin hydration.
However, it was highlighted that there is insufficient and definitive evidence regarding the effectiveness of other supplements on skin hydration (Sun and Team, 2022).

The 2021 study published by Kyoungmi Jung and her team investigated the effects of oral intake of enzymatically hydrolyzed AP collagen peptides (APCPs) on increasing skin moisture and barrier function. The study evaluated changes in stratum corneum (SC) components and demonstrated that these supplements could increase ceramide and natural moisturizing factor (NMF) content.
These findings are considered a significant step toward improving skin with functional food (Jung and Team, 2021).

The 2023 study published by Adiv A. Johnson and his team examined the effects of glycine on extending lifespan and improving health outcomes related to aging disease models. The study showed that glycine could extend lifespan by mimicking methionine restriction and activating autophagy.
These findings reveal that glycine has positive effects on the aging process and provides significant health benefits (Johnson and Team, 2023).

The 1987 study published by P. S. Leboy and his team examined increases in tRNAGly levels required for chicken Type I collagen synthesis. The study showed that these increases rely on the amount of the primary tRNAGly isoacceptor in other tissues.
These findings help us better understand the relationship between glycine tRNA levels and collagen synthesis and its role in this process (Leboy and Team, 1987).
