This fit is calculated for the concerns frequently associated with mature skin: fine lines, wrinkles, and loss of firmness. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for mature skin; other serums fit it better.

## Why this fit

- This product offers moderate benefits for your normal skin, with Ascorbic Acid and Glycerin providing antioxidant activity and humectant action to support your goals of reducing wrinkles and fine lines. Adenosine and Hydrolyzed Hyaluronic Acid further aid in hydration and wrinkle reduction, though stronger concentrations of these actives could enhance efficacy.
- The formulation is generally safe for your normal skin, as it lacks harsh ingredients and includes soothing components like Ascorbyl Glucoside and Hydrolyzed Hyaluronic Acid, minimizing irritation risk.

Sources: [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/), [Skin Research and Technology, 2024](https://pubmed.ncbi.nlm.nih.gov/38591218/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, though some treatments can also be used in the morning. Mature skin requires products with stronger concentrations of active ingredients like vitamin C, peptides, and hyaluronic acid to better reduce wrinkles and improve firmness.

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

You can use this serum with retinol, but it is best to apply retinol at night and use this vitamin C treatment in the morning to avoid overwhelming your skin. This product works for mature skin, though this skin type benefits most from a product with stronger concentrations of active ingredients for better wrinkle reduction and hydration.

### How often should I use this serum?

You can use this serum in the evening as part of your routine for simplicity and extra safety around sun exposure. This type of mature skin needs treatments featuring stronger concentrations of active ingredients like vitamin C and hyaluronic acid to better reduce wrinkles and fine lines.
Sources: [Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31975502/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum is unlikely to cause breakouts for mature skin, as it has a low risk and lacks harsh ingredients. However, a product of this type needs stronger concentrations of active ingredients and lightweight, non-greasy hydrators to give mature skin the best results.

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

It has no drying alcohol and contains fragrance (limonene and citral).
