What are collagen peptides?
Collagen peptides are short chains of 2 to 50 amino acids linked by covalent bonds and act as the building blocks of collagen which is the most abundant proteins in human body. 30% of the total protein content in the body is collagen. Collagen is the major skin component which provides structural integrity, support and strength to our skin.
Collagen Peptides in Skincare
Up to 80% of human skin contents by dry weight are collagen. The collagen levels in our skin decline with age, causing the skin to lose its firmness and strength. From mid twenties onward, a human body starts losing 1% to 1.5% of the total collagen content every year. Sagging skin is a sign of depleting levels of collagen in the skin. In skincare, collagen peptides are mainly used to restore the skin's collagen levels and lift up the skin. With its nano size particle, collagen peptides penetrate deep into the skin; stimulating collagen synthesis and restoring the youthfulness of the skin. However, collagen peptides have many more benefits for your skin.
Top 6 benefits of collagen peptides for Your Skin
1. Collagen peptides increase skin water content.
Studies showed that collagen peptides have excellent moisture retention properties. Collagen peptides stimulate the hyaluronic acid synthesis in the skin. Clinical data showed that the use of collagen peptides in skincare can improve the skin's hydration levels by around 200%.
2. Collagen peptides reduce wrinkles and fine lines.
In one of the clinical studies, more than 80% participants reported the visible reduction of wrinkles and fine lines on the face including on the skin around the eyes after using collagen peptide cream for 4 weeks,
3. Collagen peptides improve skin elasticity.
Clinical results showed that collagen peptides improve skin elasticity by up to 39% after 28 days of use.
4. Collagen peptides protect the skin from free radical damage.
Studies showed that collagen peptides exhibit excellent antioxidant activity. Collagen peptides have the ability to neutralise free radicals and prevent skin damage.
5. Collagen peptides prevent UV-induced photoageing.
UV rays stimulate melanin in the skin to produce reactive oxygen species (ROS), which can damage skin cells and cause photoageing including freckles, age spots and even skin cancer. Collagen peptides have been shown to reduce the excess production of melanin in the skin and hence collagen peptides help prevent UV-induced photoageing.
6. Collagen peptides firm up the skin.
Clinical data showed that collagen peptides firm up the skin and reduce skin sagging by 38% within 4 weeks of use.
Can all skin types benefit from collagen peptides in skincare?
Yes, all skin types can benefit from collagen peptides in skincare. Choose collagen peptide skincare products which suit your skin type. If you have an oily skin, choose collagen peptide skincare products with a light, oil-free formula. If you have dry skin, choose collagen peptide skincare products with a rich, nourishing formula.
Can you use collagen peptide skincare products on sensitive skin?
Yes you can as long as the other ingredients in the products are also suitable for sensitive skin; and before using any new product on sensitive skin always do a patch test to avoid skin irritation.
Can you use collagen peptide skincare products during pregnancy and breastfeeding?
Yes, collagen peptides are safe for use during pregnancy and breastfeeding. Always check and make sure that the other ingredients in the products are also safe for use during pregnancy and breastfeeding.
Is there any ingredient recommended to be used together with collagen peptides?
To prevent collagen loss in the skin; look for skincare products which contain collagen peptides, coenzyme Q10 and vitamin E as active ingredients. While collagen peptides stimulate collagen production in the skin; coenzyme Q10 and vitamin E help prevent collagen degradation.
When is the best time to use collagen peptide skincare products?
Collagen peptides are not phototoxic. They don't cause photosensitivity, so you can use collagen peptide skincare products at anytime during the day and night. Always check and make sure that the other ingredients in the products are also not phototoxic.
