On the relationship between glycolic acid and rosacea
In people with rosacea, facial diseases are characterized by skin flushing, papules, pustules, and even hyperplasia of rhinophytes. Its etiology is complex, or related to genetics, neurovascular regulation disorders, and microbial infections. Glycolic acid, commonly found in skin care products, is a fruit acid and has many skin care effects. As for rosacea patients, what are the advantages and disadvantages? Discuss in detail.

Glycolic acid has the ability to exfoliate, which can loosen the connections between keratinocytes, make the aging stratum corneum shed, and promote epidermal cell renewal. For normal skin, it can make the skin smooth and delicate, and even in color. However, patients with rosacea have sensitive skin and damaged epidermal barrier. The peeling effect of glycolic acid may further weaken the barrier function, making the skin more susceptible to external stimuli and exacerbating inflammation. Studies have shown that some rosacea patients who use glycolic acid products for the first time show that the skin is red, swollen, tingling, and the inflammatory response is obvious.

Furthermore, glycolic acid may affect the neurovascular regulation of the skin. The neurovascular function of rosacea patients is already disordered, and the stimulation of glycolic acid may exacerbate vasodilation and cause facial flushing. Although it can promote collagen synthesis, long-term moderate use may be beneficial to improving the texture of the skin. However, during the acute onset of rosacea, rash use of it will increase the burden on the skin.

However, the effect of glycolic acid on rosacea cannot be completely denied. If rosacea is in remission, skin inflammation is mild, and the patient's skin is well tolerated to glycolic acid, you can start with low-concentration products and try them on a small scale. Close observation of skin reaction, if no discomfort occurs, you can gradually increase the frequency and concentration of use. During this period, with soothing and repairing skin care products to protect the skin barrier.

In summary, glycolic acid has advantages and disadvantages for rosacea. If rosacea patients want to use products containing glycolic acid, they should consult a professional dermatologist first. Choose carefully according to their own skin condition, and do not use it blindly to avoid aggravating the condition.
