Yes, Hyaluronic Acid can be beneficial for closed comedones. Closed comedones are typically caused by the accumulation of dead skin cells and sebum within the hair follicles, leading to clogged pores. Hyaluronic Acid is a humectant that attracts and retains moisture, making it an excellent ingredient for hydrating the skin.

By providing hydration, Hyaluronic Acid helps to maintain the skin's moisture balance, preventing excessive dryness that can exacerbate closed comedones. Additionally, it can help to improve the overall texture and appearance of the skin by plumping and smoothing the surface.

However, it's important to note that Hyaluronic Acid alone may not be sufficient to treat closed comedones. It is often recommended to combine it with other skincare ingredients, such as exfoliants (e.g., salicylic acid or glycolic acid), to help unclog the pores and promote cell turnover. Consulting with a dermatologist or skincare professional can provide personalized advice on the best approach for your specific skin concerns.
