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

Azelaic acid helps fade dark spots and uneven skin tone by slowing down the overactive pigment production in your skin cells. It is unlikely to cause irritation and may gradually clear up stubborn marks left behind by breakouts or sun exposure.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/), [Archives of Dermatological Research, 1990](https://pubmed.ncbi.nlm.nih.gov/2114832/)

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

Salicylic acid helps fade dark spots and uneven skin tone left behind after breakouts. It gently clears away surface buildup, which may improve the look of dark marks and support a smoother, more even complexion over time.
Sources: [Dermatologic Surgery, 2009](https://pubmed.ncbi.nlm.nih.gov/19400885/), [Dermatologic Surgery, 1999](https://pubmed.ncbi.nlm.nih.gov/9935087/)

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

This treatment goes in the evening routine after cleansing and before your moisturizer. Treatments with actives are placed in the evening for simplicity and extra safety around sun exposure.

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

You can use this treatment alongside a retinol, but it is best to apply them on alternate nights or separate them into your morning and evening routines to keep your skin calm and avoid irritation. Layering them together may be too strong for your skin, so introducing them slowly helps prevent dryness.

### How often should I use this treatment?

This treatment is a great fit for skin with dark spots and can be applied in your evening routine, starting just once a week. Azelaic acid and salicylic acid effectively target pigmentation and gently smooth the skin while keeping irritation very low, and you can carefully use it more often if your skin tolerates it well.

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

This treatment is unlikely to clog pores or cause breakouts for your skin, as its ingredients effectively target dark spots and provide gentle exfoliation without heavy oils. It helps clear the skin safely while evening out your skin tone.
Sources: [Dermatology and Therapy, 2024](https://pubmed.ncbi.nlm.nih.gov/38734843/)

### Is this treatment fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
