This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other moisturizers fit it better.

## Why this fit

- Offers moderate suitability for your normal skin, as Glycerin and Sodium Hyaluronate provide excellent hydration and plumping effects, while Saccharomyces Rice Ferment Filtrate and Stearyl Glycyrrhetinate offer some calming benefits for redness and irritation.
- The formula's humectant action is well-suited for normal skin, though it lacks more potent actives to fully address your primary concerns.
- The product is generally safe for your sensitive skin, with minimal risk of irritation from ingredients like alcohol, fragrance, and ascorbic acid.

([Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40722956/))

## Questions and answers

### How well does Tatcha The Dewy Serum work for sensitive skin?

Tatcha The Dewy Serum works moderately well for sensitive skin, as it provides good hydration and helps calm redness, though other products fit this skin type better. A product of this type needs effective hydrating and soothing ingredients that calm redness without any risk of irritation, along with rich moisture-retention components.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Which ingredients make this serum a good fit for sensitive skin?

This serum works for sensitive skin because glycerin and sodium hyaluronate provide good hydration while keeping the skin calm, and saccharomyces rice ferment filtrate helps soothe redness and irritation. A product of this type needs effective hydrating and soothing ingredients that address redness and irritation without posing any risk of irritation, along with beneficial extracts and multiple types of hyaluronic acid to maintain skin balance and vitality.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Squalane do for sensitive skin?

Squalane helps calm sensitive skin by defending against everyday irritation and keeping it smooth and soft. It is unlikely to cause irritation and supports your skin barrier so it stays comfortable and hydrated.
Sources: [International Journal of Molecular Sciences, 2017](https://pubmed.ncbi.nlm.nih.gov/29280987/)

### What does Hyaluronic Acid do for sensitive skin?

Hyaluronic acid helps calm and hydrate sensitive skin while supporting the skin barrier to keep it soft and comfortable. Clinical studies show it improves surface moisture and reduces dryness, roughness, and redness without irritation.
Sources: [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/41037531/), [Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/29356277/)

### Where does this serum go in a skincare routine for sensitive skin?

This treatment goes in your evening routine after your soothing toner and before your moisturizer. Putting it in the evening keeps things simple and adds extra safety around sun exposure, while a product for this skin needs stronger calming ingredients and richer hydrators to truly soothe and comfort it.

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

You can use this treatment alongside retinol by applying it before your retinol product to help keep your skin hydrated and calm. To work best for sensitive skin, a product of this type needs gentle barrier-restoring ingredients and soothing agents to help prevent dryness and irritation.

### How often should I use this serum?

You can use this treatment in the evening as part of your routine. Daily use of moisturizing treatments helps improve skin hydration and barrier function.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32141711/), [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/)

### Can this serum clog pores, cause breakouts or purging for sensitive skin?

This serum is unlikely to clog pores or cause breakouts for sensitive skin, as the risk of breakouts with this formula is low. Sensitive skin needs lightweight, non-greasy hydrators and calming ingredients that soothe redness without heavy oils that trap debris.

### Can I use this serum around the eyes or on my body?

You can use this moisturizing treatment around the eyes, where skin is thin, and on your body. The formula is generally safe for sensitive skin with a low risk of irritation, though it may not address all specific concerns.

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

It contains fragrance (parfum, citral, limonene, and linalool) and drying alcohol (alcohol).
