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 niacinamide helps with seboregulation and glycerin provides hydration, but it lacks stronger ingredients for comprehensive oil control.
- The presence of aloe barbadensis leaf juice and camellia sinensis leaf extract ensures a gentle experience, minimizing irritation risks for your oily skin.
- The product is safe for your skin, with no harsh ingredients and a focus on soothing components.

## What reviewers say

The serum is widely praised for its hydrating properties and lightweight, whipped consistency that leaves skin feeling smooth and refreshed. However, many users and experts caution that it functions more like a basic moisturizer than a targeted serum, and those with acne-prone skin should be wary of potentially pore-clogging ingredients like coconut oil and cocoa butter.

## Questions and answers

### How well does TRULY Glass Skin Facial Serum work for oily skin?

TRULY Glass Skin Facial Serum works moderately well for oily skin, as niacinamide helps balance oil and glycerin provides lightweight hydration. It has a very safe and gentle formula, but oily skin needs a treatment with stronger oil control, a high concentration of hyaluronic acid, and soothing ingredients like allantoin to maintain balance and refine pores.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Niacinamide helps balance oil and glycerin provides hydration, while aloe juice and green tea extract keep the formula gentle and soothing on oily skin. Oily skin often needs a moisturizing treatment with ingredients like hyaluronic acid to maintain lightweight moisture and ceramides to keep pores clear.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Jojoba Oil do for oily skin?

Jojoba oil helps calm oily and breakout-prone skin by reducing blemishes and inflammation. It is unlikely to clog pores and helps keep the skin feeling balanced and smooth.
Sources: [Forschende Komplementarmedizin, 2012](https://pubmed.ncbi.nlm.nih.gov/22585103/), [Giornale Italiano Di Dermatologia E Venereologia, 2013](https://pubmed.ncbi.nlm.nih.gov/24442052/)

### What does Niacinamide do for oily skin?

Niacinamide helps balance oily skin by significantly reducing excess oil production and shine. It is well tolerated and may improve skin texture without clogging pores.
Sources: [Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

This treatment goes in the evening routine after cleansing and before moisturizing. Putting it at night keeps it simple and avoids extra safety concerns around sun exposure.

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

You can use this treatment with retinol by applying it after your retinol step to help soothe the skin. This product works for oily skin, though other products fit it better because it lacks stronger ingredients for comprehensive oil control.
