The main ingredients of hyaluronic acid collagen peptides include collagen peptides and hyaluronic acid. When used in appropriate amounts, these ingredients generally exert positive effects such as improving skin tone, moisturizing, whitening, lightening pigmentation, and anti-aging. Possible side effects may include allergic reactions, gastrointestinal discomfort, and liver or kidney damage.

Some individuals may experience allergic reactions to these ingredients, manifesting as symptoms such as redness, swelling, itching, or rash. Therefore, it is recommended to perform a skin test on a small area before initial use of products containing these ingredients and observe for 24-48 hours to ensure no adverse reaction occurs; excessive intake of hyaluronic acid collagen peptides may burden the gastrointestinal tract, leading to problems such as diarrhea and bloating; long-term and excessive intake may also place a certain burden on the liver and kidneys.

When using hyaluronic acid collagen peptides, attention should be paid to selecting products manufactured by reputable manufacturers to ensure product quality and safety; follow the dosage instructions provided in the product manual or by a physician to avoid excessive intake; monitor your own response and discontinue use immediately if any adverse reactions occur, and seek medical advice. Many hyaluronic acid collagen peptide products on the market vary in quality. Consumers should choose brands with good reputations and avoid purchasing uncertified or untraceable products.
