Topical Collagen Jelly vs Edible Collagen: What’s the Difference?

Collagen, a protein that makes up about a third of the protein content in the human body, plays a crucial role in maintaining skin health. It contributes to skin's elasticity, hydration, and overall appearance. Age, however, gradually decreases the body's ability to produce collagen, leading to signs of aging like wrinkles and sagging skin. This has led to the popularity of collagen supplements, both topical and edible, in the skincare industry. But what's the difference between these two? Let's dive in.

Topical Collagen Jelly

Topical collagen, including collagen jellies, creams, and serums, is applied directly to the skin. The idea is that by applying collagen topically, it can permeate the skin and address aging signs directly.

Efficacy of Topical Collagen

However, the efficacy of topical collagen is a subject of debate among researchers. Collagen molecules are relatively large and may not be able to penetrate the skin's surface effectively. Some studies suggest that the efficacy of topical collagen is limited to the outermost layer of skin, the epidermis, and may not reach the dermis where collagen is produced (Proksch et al., 2014).

Despite this, topical collagen can still deliver some benefits. Research has shown that topical collagen can increase skin hydration and reduce the depth of facial wrinkles (Proksch et al., 2014).

Edible Collagen

Edible collagen, on the other hand, is ingested orally. It's typically available in forms like powders, capsules, and gummies. The body breaks down the ingested collagen into amino acids, which are then used to produce new collagen.

Efficacy of Edible Collagen

Research suggests that edible collagen can enhance skin health more effectively than topical collagen. A study found that participants who consumed collagen peptides for 8 weeks experienced increased skin elasticity compared to those who took a placebo (Proksch et al., 2014).

Another study found that edible collagen can significantly increase skin hydration and collagen density in the dermis, and reduce wrinkle depth (Asserin et al., 2015).

Conclusion

Both topical and edible collagen have their merits. While topical collagen may provide immediate hydration and surface-level benefits, edible collagen appears to offer more comprehensive skin health benefits by enhancing collagen production from within. However, more research is needed to understand the full potential of collagen in skincare.

Remember, it's always important to consult a healthcare provider or a dermatologist before starting any new skincare routine or supplement regimen.
