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

Brand: [Kiehl's](https://lovi.care/skincare/uk/brands/kiehl-s)
Category: [Serums and treatments](https://lovi.care/skincare/uk/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 anti-aging benefits for smoothing fine lines and wrinkles due to adenosine and hydrolyzed soy protein, which are suitable for your oily skin. Glycerin provides humectant action, though the formula lacks strong seboregulation for your oily shine.
- The product provides general skincare benefits like hydration and soothing, which are supportive but not directly targeted at managing excess oil.

- 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.

## Questions and answers

### Why is Kiehl's Age Defender Power Serum a weak match for oily skin?

This serum is a weak match because it lacks strong ingredients to control excess oil and shine. Treatments for oily skin need ingredients like niacinamide, ferulic acid, zinc PCA, and soothing extracts that manage oil production and pores while keeping the skin comfortable.

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

This serum is a weak match for oily skin because it lacks ingredients that control oil and shine, even though it provides hydration and smoothing benefits. Treatments that fit oily skin better need ingredients like niacinamide, ferulic acid, zinc PCA, and soothing extracts to manage excess oil and enlarged pores without clogging pores.

### What does Cypress Extract do for oily skin?

Cypress extract helps keep oily skin clear and balanced by reducing excess shine and soothing irritation. This type of skin needs lightweight, purifying ingredients that control oil without clogging pores or causing dryness.

### What does Glycerin do for oily skin?

Glycerin helps keep oily skin hydrated without feeling heavy and supports the skin barrier. Because this product is a weak fit for your skin, an ideal product of this type needs lightweight hydrators and ingredients that balance oil while protecting the skin.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [International Journal of Toxicology, 2019](https://pubmed.ncbi.nlm.nih.gov/31840548/)

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

This serum goes in your evening routine, applied after cleansing and before your moisturizer. Because this product is a weak match for oily skin, an ideal treatment for this skin type needs oil-controlling and shine-reducing ingredients.

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

You can use this serum with retinol by applying it after your retinol treatment to help soothe and hydrate your skin. This product offers general hydration and anti-aging benefits, but oily skin also needs strong oil-balancing ingredients and lightweight textures to manage shine effectively.

### How often should I use this serum?

Use this treatment in the evening for simplicity and extra safety around sun exposure. Oily skin needs a product of this type that also includes ingredients to control excess oil.

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

This serum is unlikely to cause purging since it does not contain exfoliating acids or retinoids, but it may feel heavy or lack oil control for oily skin. Oily skin generally needs lightweight, oil-balancing ingredients like niacinamide or salicylic acid to help manage excess shine and keep pores clear.

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

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