### Which ingredients make this toner a good fit for acne-prone skin?

This toner is an exceptional fit for acne-prone skin because betaine salicylate and glycerin gently clear dead skin and balance oil while keeping moisture locked in. Panthenol and centella asiatica extract further help calm the skin and reduce irritation, making the complexion feel much smoother and more comfortable.
Sources: [Indian Journal of Pharmaceutical Sciences, 2016](https://pubmed.ncbi.nlm.nih.gov/27168678/), [American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/)

### What does Bha do for acne-prone skin?

BHA helps clear acne-prone skin by clearing out pores to reduce both inflammatory and non-inflammatory breakouts. It also helps calm redness and lower oil production, and is unlikely to cause harsh side effects when used regularly.
Sources: [BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/), [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/37941097/)

### What does Chestnut Extract do for acne-prone skin?

Sources: [International Journal of Molecular Sciences, 2024](https://pubmed.ncbi.nlm.nih.gov/38731983/)

### Where does this toner go in a skincare routine for acne-prone skin?

This exfoliating toner fits into your routine as a cleansing toner used in the evening, or as a hydrating toner in the morning. Lovi routines start exfoliating toners once a week, and people who tolerate them well and see good results can carefully use them more often.

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

You can use this exfoliating toner with retinol by applying the toner first after cleansing, waiting for it to absorb, and then following with your retinol. Because both ingredients actively renew the skin, using them together may occasionally cause dryness or irritation, so it helps to start slowly just a few nights a week to see how your skin reacts.

### How often should I use this toner?

Start by using this exfoliating toner once a week, and if your skin tolerates it well and you see good results, you can carefully use it more often. This gentle approach helps balance oil production and keeps your complexion calm without causing irritation.

### Can this toner clog pores, cause breakouts or purging for acne-prone skin?

This toner is unlikely to clog pores or cause breakouts because it contains no harsh ingredients and features soothing components that help keep skin calm. It may cause mild purging as the BHA gently exfoliates dead skin cells and clears out pores.
Sources: [BioMed Research International, 2020](https://pubmed.ncbi.nlm.nih.gov/33150170/)

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

Yes, it has no fragrance and no drying alcohol.
