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

Brand: [47 Skin](https://lovi.care/skincare/ca/brands/47-skin)
Category: [Serums and treatments](https://lovi.care/skincare/ca/best/serums)

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.

A weak match for oily skin; the serums alongside fit it better.

## Why this fit

- Offers moderate treatment for blemishes and scars due to allantoin aiding skin repair, but the emollient action of dimethicone and cyclopentasiloxane is not optimal for your oily skin and oily shine.
- While the product provides general skincare benefits like hydration and cleansing, these are mostly supportive and irrelevant to your primary concern of oily shine.

## What reviewers say

Based on a very large amount of data, this serum is frequently praised as a 'miracle' solution for stubborn acne and scarring, with users crediting its unique 'Silver Chitoderm' ingredient for clearing breakouts without drying out the skin.

## How to apply

- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- Apply the serum after cleansing and toning, but right before your moisturizer for the best results.
- Gently press 2-3 drops of the serum into your skin. Let it absorb ⏱ for a minute before applying the next product.
- Apply the serum on clean and dry skin since your skin is not sensitive and you want to target oily shine. This helps control excess oil throughout the night.
- Avoid the delicate eye area and do a patch test before using the serum for the very first time.

## Questions and answers

### Why is 47 Skin Anti-Blemish & Scar Repair Serum a weak match for oily skin?

This serum is a weak match because the smoothing ingredients like dimethicone are not optimal for oily skin and oily shine, while its hydrating benefits are mostly irrelevant to your primary concerns. A product for oily skin needs ingredients like niacinamide to control excess oil and zinc PCA to manage enlarged pores, along with soothing extracts and lightweight hydrators.

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

Dimethicone and cyclopentasiloxane make this serum a weak match for oily skin because their heavy smoothing action is not optimal and can worsen oily shine. A treatment for this skin needs ingredients like niacinamide, zinc PCA, and ferulic acid that control excess oil and pores without clogging.

### What does Silver do for oily skin?

Silver helps calm red, angry breakouts and keeps oily skin clear by fighting the bacteria that cause pimples. It is unlikely to clog pores, making it a safe choice for oily skin types.

### What does Chitosan do for oily skin?

Chitosan helps oily skin by absorbing excess oil and balancing the skin surface without feeling heavy. It is unlikely to clog pores and may help keep the skin feeling fresh and clean throughout the day.

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

This serum goes in the evening routine, after cleansing and before moisturizing, to keep things simple and safe around sun exposure. Because it is a weak match for oily skin, a product of this type needs lightweight ingredients that help control shine without adding heavy smoothing agents.

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

You can use this serum with retinol by applying the retinol first and following with the serum. Because this product contains heavy smoothing ingredients that can weigh down oily skin and worsen shine, it may not be ideal for your routine. An oily skin type needs lightweight treatments with exfoliating acids and oil-controlling ingredients rather than heavy smoothing agents.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38102855/)

### How often should I use this serum?

This serum is used in the evening once a week to start, as oily skin needs lightweight formulas and gentle exfoliating ingredients like lactic acid to control excess shine without heavy skin-softening oils.

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

This serum may not be the best fit for oily skin because the heavy smoothing ingredients like dimethicone can add an unwanted oily shine. Oily skin works best with lightweight, oil-free hydration and gentle exfoliating acids that clear pores without feeling heavy.

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

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
