### What does Hyaluronic Acid do for skin with dark spots?

Hyaluronic acid is unlikely to directly fade dark spots, but it helps keep dry and uneven skin plump and deeply hydrated. To effectively target dark spots, this type of skin needs brightening ingredients like vitamin C or niacinamide alongside your hydrator.

### Where does this serum go in a skincare routine for skin with dark spots?

This treatment serum goes in your evening routine, applied after cleansing and before your moisturizer. Putting it on at night keeps things simple and provides extra safety around sun exposure.

### Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying the serum first and following with your retinol, or by using them on alternating nights to keep your skin calm. Because both ingredients work actively on your skin, spacing them out or introducing them slowly helps prevent any dryness or irritation.

### Can this serum clog pores, cause breakouts or purging for skin with dark spots?

Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/)
