The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Spain.

Brand: [Tatcha](https://lovi.care/skincare/es/brands/tatcha)
Category: [Moisturizers and moisturizing serums](https://lovi.care/skincare/es/best/moisturizers)

This fit is calculated for the concerns frequently associated with oily skin: shine, enlarged pores, blackheads, and blemishes. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for oily skin; other moisturizers fit it better.

## Why this fit

- Offers moderate suitability for your oily skin, as Saccharomyces Rice Ferment Filtrate and Glycerin provide humectant action to hydrate and plump, but it lacks sufficient seboregulating components for optimal oil control.
- While it offers excellent moisturizing due to Glycerin and Sodium Hyaluronate, its benefits are mostly supportive and irrelevant for addressing your oily shine.
- The product is generally safe for your oily skin, with minimal risks of irritation from alcohol and fragrance.

## Questions and answers

### How well does The Dewy Serum work for oily skin?

This serum works moderately well for oily skin, as it provides hydration with glycerin and rice ferment filtrate, but it lacks enough oil-controlling ingredients for your shine. Oily skin of this type needs a formula with niacinamide to help balance oil production and green tea extract to soothe without feeling heavy.
Sources: [Journal of Clinical Medicine, 2021](https://pubmed.ncbi.nlm.nih.gov/34198790/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Saccharomyces Rice Ferment Filtrate and glycerin make this serum a good fit for oily skin by providing hydration to plump the skin. Oily skin also needs ingredients like niacinamide and green tea extract to help control oil production and balance shine.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Squalane do for oily skin?

Squalane helps keep oily skin soft and smooth without feeling heavy, though oxidized forms may sometimes trigger irritation. To work well for oily skin, this type of product needs lightweight, non-clogging ingredients that balance moisture without adding excess grease.
Sources: [The Journal of Investigative Dermatology, 2006](https://pubmed.ncbi.nlm.nih.gov/16778793/)

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

Hyaluronic acid helps oily skin by reducing extra oil and sebum production without causing irritation. Clinical studies show it successfully balances oil levels while keeping the skin comfortable.
Sources: [The Journal of Investigative Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28163068/)

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

This treatment goes in the evening routine after cleansing and toning, followed by your moisturizer. Oily skin works best with products that contain oil-controlling components to help manage shine.

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

You can use this serum with retinol by applying the serum first to hydrate your skin, followed by your retinol treatment. This product is generally safe for your skin, though it lacks the oil-controlling ingredients needed to properly balance excess shine.

### How often should I use this serum?

You can use this treatment in your evening routine as part of your daily skincare steps. Oily skin of this type needs oil-controlling ingredients to manage shine effectively.

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

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

This serum is safe to use around the eyes and on the body, though it provides only moderate suitability for oily skin due to its lack of oil-balancing components. To better care for oily skin, a product of this type needs added oil-regulating ingredients that help manage shine.

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

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