## Questions and answers

### How well does Curology Formula work for combination skin?

Curology Formula works reasonably well for combination skin by using tretinoin and azelaic acid to target breakouts and oily shine, while clindamycin helps clear up acne-causing bacteria. It is safe for this skin type and is unlikely to cause irritation. However, a treatment for combination skin needs ingredients like niacinamide, propolis, and zinc PCA to provide balanced hydration and regulate oiliness without risking imbalance.

### Which ingredients make this treatment a good fit for combination skin?

Tretinoin, azelaic acid, and clindamycin make this treatment a good fit by reducing acne blemishes, targeting oily shine, and clearing acne-causing bacteria. To fit combination skin even better, a treatment of this type needs ingredients like niacinamide, zinc PCA, and propolis to balance hydration and regulate oiliness.
Sources: [Pharmaceutics, 2021](https://pubmed.ncbi.nlm.nih.gov/33923739/), [Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34146120/)

### What does Tretinoin do for combination skin?

Tretinoin helps clear breakouts and smooth out uneven texture by speeding up skin renewal. Because it can be drying, combination skin needs a gentle moisturizer and daily sunscreen to protect the skin barrier while using this ingredient.
Sources: [Archives of Dermatological Research, 2022](https://pubmed.ncbi.nlm.nih.gov/34146120/), [International Journal of Women's Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35620028/)

### What does Azelaic Acid do for combination skin?

Azelaic acid helps combination skin by calming redness, clearing breakouts, and fading dark spots while keeping the skin smooth. It is unlikely to irritate dry areas while working on oily spots. Combination skin of this type needs a balanced routine with gentle exfoliants and soothing hydrators.
Sources: [Postepy Dermatologii I Alergologii, 2023](https://pubmed.ncbi.nlm.nih.gov/38282869/), [Journal of Drugs in Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/26355614/)

### Where does this treatment go in a skincare routine for combination skin?

This treatment goes in the evening routine after cleansing and before moisturizing. Combination skin works well with treatments like this, though other products fit it better by providing extra soothing hydration and gentle balancing ingredients to keep both dry and oily areas comfortable.

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

You can use this treatment with niacinamide by applying niacinamide first in your routine to keep your combination skin calm and smooth. Combination skin works best with products that balance oil and add gentle moisture.

### How often should I use this treatment?

You can use this treatment in your evening routine once a week to start, then carefully use it more often if your skin handles it well. This type of product for combination skin needs ingredients that help target breakouts and oily shine while keeping the skin calm.

### Can this treatment clog pores, cause breakouts or purging for combination skin?

This treatment is unlikely to clog pores or cause new breakouts on combination skin, as Tretinoin and Azelaic Acid help clear blemishes and reduce oily shine. However, the skin may experience some mild purging or peeling when first starting out as the ingredients promote skin renewal. Combination skin of this type needs products that balance oil and promote gentle cell turnover without causing irritation.
