## Why this fit

- Offers moderate soothing and toning for your combination skin, as minerals like calcium and magnesium help calm irritation and balance the skin, while zinc and copper provide mild astringent and antioxidant activity.
- The presence of selenium and zinc offers general soothing and hydration benefits for your acne-prone skin, though these minerals are not specialized for treating active breakouts.
- The product is safe for your skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

A product of this type needs calming and hydrating ingredients like chamomile, oat extract, or aloe to effectively address acne and blemishes while maintaining hydration without causing imbalance.

### What does Thermal Spring Water do for acne-prone skin?

Thermal spring water helps calm acne-prone skin by reducing dryness and stinging while improving overall tolerability when used alongside standard acne care. It may also help manage acne and reduce local irritation.

### What do Naturally Properties do for acne-prone skin?

Naturally Properties helps acne-prone skin by balancing oil production, calming redness, and targeting acne-causing bacteria. This product type needs ingredients that regulate oil and soothe irritation to keep oily skin clear and comfortable.
Sources: [Phytotherapy Research, 2021](https://pubmed.ncbi.nlm.nih.gov/32816329/), [Molecules, 2019](https://pubmed.ncbi.nlm.nih.gov/30634461/)

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

This toner goes in the morning routine after cleansing and before moisturizing, and also after a cleansing mask in your weekly routine. An average fit for your acne-prone skin means this product needs specialized ingredients that target active breakouts.

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

You can use this toner with retinol by applying it right after cleansing to calm and hydrate your skin before you put on your retinol treatment. It is unlikely to cause irritation, but acne-prone skin often works better with products that include specialized blemish-fighting ingredients and barrier-restoring components like ceramides.

### How often should I use this toner?

You can use this soothing toner daily to help calm irritation and hydrate your acne-prone skin. Because these minerals are not specialized for treating active breakouts, this skin also needs targeted ingredients like salicylic acid or benzoyl peroxide to effectively clear blemishes.
Sources: [Journal of Controlled Release, 2025](https://pubmed.ncbi.nlm.nih.gov/40254135/), [Wound Repair and Regeneration, 2007](https://pubmed.ncbi.nlm.nih.gov/17244314/)

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

This soothing toner is unlikely to clog pores or cause breakouts for acne-prone skin, as it contains no harsh or pore-clogging ingredients. However, it is not specialized for treating active breakouts, so acne-prone skin still needs targeted ingredients like salicylic acid or benzoyl peroxide to properly clear blemishes.

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

Yes, it has no fragrance and no drying alcohol.
