Category: [Moisturizers and moisturizing serums](https://lovi.care/skincare/best/moisturizers)

This fit is calculated for the concerns frequently associated with acne-prone skin: breakouts, blackheads, and post-acne marks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for acne-prone skin; other moisturizers fit it better.

## Why this fit

- Offers moderate moisturizing and soothing benefits for your combination, acne-prone skin due to the presence of glycerin and panthenol, which hydrate and enhance barrier resilience.
- While it provides general hydration, the formula lacks targeted ingredients to effectively address your specific concerns of acne, blemishes, and breakouts.
- The safety profile is excellent, with no risks of irritation for your combination skin due to the absence of prohibited or harsh ingredients.

## What the research says

- Topical dexpanthenol acts as a moisturizer, improves stratum corneum hydration, accelerates wound healing and epidermal regeneration, reduces erythema, and improves symptoms of skin irritation compared to vehicle or no pretreatment.

## What reviewers say

Based on a very large amount of data, this serum is highly praised for its intense hydration and ability to visibly plump the skin, leading to immediate improvements in bounce and a reduction in fine dehydration lines. While many users with sensitive skin find it gentle and soothing, a significant number dislike its strong floral fragrance and sticky finish.

- Liked: Intense hydration (mostly mentioned)
- Liked: Smoothes fine lines (often mentioned)
- Disliked: Strong fragrance (often mentioned)
- Liked: Fast absorption (sometimes noted)
- Liked: Gentle on sensitive skin (sometimes noted)
- Disliked: High price point (sometimes noted)

## How to apply

- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help keep breakouts under control.
- Apply after your cleanser and toner, and make sure to use your SPF right after in the morning.
- Gently spread a small amount of moisturizer over your face using soft motions. Let it absorb into the skin for a minute before getting dressed or applying makeup.
- Apply on slightly damp skin to help lock in extra moisture. This keeps your combination skin balanced without feeling heavy.
- Avoid the eye area and do a patch test before your first use. Stop using if you feel any irritation.

## Questions and answers

### How well does La Roche-Posay Hyalu B5 work for acne-prone skin?

La Roche-Posay Hyalu B5 Serum works moderately well for acne-prone skin by offering basic hydration and calming benefits, though it lacks targeted ingredients for breakouts. To fit this skin better, a product of this type needs acne-fighting ingredients like Niacinamide along with deeply hydrating components that control excess oil.
Sources: [American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/), [The Journal of Dermatological Treatment, 2017](https://pubmed.ncbi.nlm.nih.gov/27425824/)

### Which ingredients make this serum a good fit for acne-prone skin?

Glycerin and panthenol make this serum a fit by giving your acne-prone skin moderate moisture and a calm feel. Because it lacks targeted ingredients for breakouts, a product for this skin needs ingredients like niacinamide and hyaluronic acid to manage blemishes while keeping moisture balanced.
Sources: [American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/), [The Journal of Dermatological Treatment, 2017](https://pubmed.ncbi.nlm.nih.gov/27425824/)

### What does Hyaluronic Acid do for acne-prone skin?

Hyaluronic acid helps acne-prone skin by soothing irritation, calming redness, and keeping the skin balanced without clogging pores. When combined with targeted ingredients like zinc oxide, it may also help reduce breakouts.
Sources: [Biomedicines, 2025](https://pubmed.ncbi.nlm.nih.gov/41007718/), [Drug Delivery, 2017](https://pubmed.ncbi.nlm.nih.gov/28155509/)

### What does Panthenol do for acne-prone skin?

Panthenol helps soothe acne-prone skin while keeping it hydrated and supporting the skin barrier. It is unlikely to cause irritation and may reduce redness, making it a gentle option for skin that breaks out.
Sources: [Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38366684/)

### Where does this serum go in a skincare routine for acne-prone skin?

This serum goes in the evening routine after cleansing and before moisturizing, which keeps it simple and safe around sun exposure. To properly care for acne-prone skin, this type of product needs targeted blemish-fighting ingredients alongside the gentle hydration it already provides.

### 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 and calm your skin, followed by your retinol treatment. This approach helps reduce potential irritation while keeping your face feeling soft and smooth.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/), [American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/)

### How often should I use this serum?

You can use this serum in your evening routine daily, as your routine places treatments in the evening for simplicity and extra safety around sun exposure. Some serums like this could also be used in the morning or twice a day if desired.

### Can this serum clog pores, cause breakouts or purging for acne-prone skin?

This serum is unlikely to cause irritation or breakouts on acne-prone skin, but because it lacks targeted ingredients for blemishes, this skin type typically needs a product with acne-fighting actives like salicylic acid or benzoyl peroxide.

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

You can use this serum on your body and around your eyes, as it is very safe and unlikely to irritate these areas. However, because skin is thinner around the eyes and varies in thickness across the body, this type of product works best when it also includes targeted ingredients for specific localized concerns.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/)

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

It contains fragrance (parfum) and drying alcohol (alcohol denat).
