Two kiwis are enough, the easiest scientific habit to transform your skin
Research shows that adding just two kiwis to your daily diet can enhance your skin’s health. Known for promoting collagen production and improving skin thickness and regeneration, this fruit is gaining attention as a ‘natural remedy’ for restoring skin elasticity and vitality without dermatological treatments.
Firm Skin, the Science Behind ‘Gold Kiwi’
The skin is one of the first body parts to show signs of aging. Reduced collagen leads to thinner skin and wrinkles, a process that’s part of natural aging and difficult to avoid. The University of Otago in New Zealand has focused its research on the relationship between skin health and dietary Vitamin C.
The research team used the ‘Sun Gold variety’ of kiwis, rich in Vitamin C, for their experiment. Participants consumed two gold kiwis every day for eight weeks, equating to an additional 250mg of daily Vitamin C, comparable to 3.5 medium-sized oranges, 10 large strawberries, or 8 tangerines.
24 Participants, Unanimously Experienced Skin Improvement
The experiment targeted 24 healthy adults living in Christchurch, New Zealand and Hamburg, Germany. Their skin tissues were analyzed before and after the experiment, resulting in clear findings. Skin layers, from dermis to epidermis, showed positive changes as blood Vitamin C levels increased.
“All participants showed increased skin thickness and improved skin tissue regeneration abilities.”
With stimulated collagen production, skin structural thickness increased, and the epidermis displayed enhanced cell regeneration, resulting in healthier and more vibrant skin tones. As blood Vitamin C levels rose, more Vitamin C was delivered to skin cells.
Ingested Vitamin C, Actually Delivered to the Skin
Many wonder, “Do the nutrients I eat really reach my skin?” The skin, being the outermost organ, may face complex timing and mechanisms in nutrient delivery through bloodstream. However, this research provided a definitive answer.
The findings showed a significant increase in Vitamin C concentrations in both skin tissues and plasma after kiwi consumption, leading to direct changes in all skin layers. This increase in Vitamin C was associated with boosted collagen production in the skin.
“The skin reflects dietary changes much more quickly than we think.”
This is an assessment by Professor Margreet Vissers, the lead researcher. She emphasizes that the skin can respond more sensitively to dietary changes than other body organs.
Is Ingested Vitamin C More Effective Than Topical Skincare Products?
Many people use creams or serums containing Vitamin C for skincare. However, the research team explained that dietary intake—consuming Vitamin C—can have a deeper and broader impact on the skin than topical applications.
The outermost layer of skin, the stratum corneum, is a waterproof barrier composed of oils, making it difficult for water-soluble Vitamin C to be absorbed from the surface. Moreover, Vitamin C’s efficacy decreases once exposed to air due to oxidation. In contrast, dietary intake allows Vitamin C to be effectively delivered to deeper skin layers via the bloodstream.
Collagen Supplements? Direct Synthesis is Key
While collagen supplements have gained attention as skin health products, there is insufficient scientific evidence to prove they truly convert into skin collagen. Professor Vissers commented on this matter.
“The belief that consuming collagen supplements will increase skin collagen is a misconception. Skin collagen is directly synthesized by skin cells.”
The essence of collagen production lies not in the raw material itself but in the catalysts that promote collagen synthesis. Vitamin C is the substance that fulfills this role most effectively. Therefore, the conclusion is drawn that regular consumption of Vitamin C-rich foods is a more scientific approach to skin health than collagen supplements.
Easily Accessible Sources of Vitamin C, You Can Make the Change Now
Vitamin C is found abundantly in common ingredients. Gold kiwi, bell pepper, broccoli, strawberries, and tangerines are all well-known for their high Vitamin C content. Including these foods in your daily diet can infuse vitality and energy into your skin.
Dietary intake benefits not only skin health but also overall wellness, such as strengthening immunity, protecting cells, and reducing inflammation. Therefore, a Vitamin C-rich diet is a fundamental health strategy recommended for everyone.
The importance of Vitamin C for skin health is evidenced by research. is dedicated to providing you with naturally healthy beauty.
