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 moisturizing for your oily skin due to birch sap and sodium hyaluronate, which hydrate and enhance barrier resilience without adding excess oil. Glycerin further supports general hydration, though specialized ingredients for controlling oily shine are lacking.
- The formula is highly suitable for oily skin, providing humectant action and hydration without contributing to oiliness.
- The safety profile is excellent, with no risks of irritation for your oily skin due to the absence of harsh ingredients and the presence of soothing components like birch sap and dipotassium glycyrrhizate.

## What the research says

- A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women. ([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- Betula alba bark extract and Empetrum nigrum fruit juice upregulated barrier genes, strengthened the skin barrier, and showed significantly better skin restructuring, hydration, and TEWL compared to placebo and 3% niacinamide.

- A birch juice spray decreased lactic acid sting test scores, transepidermal water loss rates, skin blood perfusion, and redness, while increasing stratum corneum hydration and sensory nerve thresholds at 5 Hz in participants with sensitive skin compared to a control spray. ([Archives of Dermatological Research, 2023](https://pubmed.ncbi.nlm.nih.gov/36961534/))
- Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control. ([Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/))
- Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction. ([Clinical Oral Investigations, 2022](https://pubmed.ncbi.nlm.nih.gov/34623507/))
- Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days. ([BMC Oral Health, 2019](https://pubmed.ncbi.nlm.nih.gov/31311529/))

([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))

- Treatment with topical formulations containing beta-glucan combined with nanofractional radiofrequency plus magnetic nanofractional radiofrequency showed the best efficacy and was tolerable and effective in Chinese women with abdominal stretch marks compared to control groups.

## Questions and answers

### How well does Round Lab Birch Juice Serum work for oily skin?

This serum works moderately well for oily skin by providing hydration through birch sap and sodium hyaluronate without adding excess oil, though other products fit it better because they also include specialized ingredients to control oily shine. To work best for oily skin, a product of this type needs peptides and hydrating agents that maintain a lightweight texture, along with ingredients that manage shine without heavy oils or clogged pores.

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

This serum works well for oily skin because birch sap, sodium hyaluronate, and glycerin provide moderate moisture and support skin barrier strength without adding extra oil. It is also unlikely to cause irritation due to soothing ingredients like dipotangent glycyrrhizate. Oily skin often benefits from lightweight hydrators combined with peptides and specialized ingredients to control excess shine.

### What does Birch Juice do for oily skin?

Birch juice helps keep oily skin calm and hydrated by soothing redness and reducing water loss while balancing moisture. It is unlikely to clog pores and works well to keep your face feeling smooth and fresh.
Sources: [Archives of Dermatological Research, 2023](https://pubmed.ncbi.nlm.nih.gov/36961534/)

### What does Hyaluronic Acid do for oily skin?

Hyaluronic acid helps oily skin by reducing extra oil and sebum production without causing irritation. Clinical studies show it successfully balances oil levels while keeping the skin comfortable.
Sources: [The Journal of Investigative Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28163068/)

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

This serum goes in your evening routine after cleansing and before moisturizing, which keeps application simple and safe around sun exposure. You may also use it in the morning or twice a day if your skin tolerates it well.

### 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 your skin and then following with your retinol treatment. This approach helps maintain moisture while your skin adjusts, though an oily skin type also benefits from specialized ingredients that help control excess shine.

### How often should I use this serum?

You can use this treatment in the evening as part of your routine, or twice a day if your skin tolerates it well. Its gentle formula hydrates your oily skin without adding excess oil and has an excellent safety profile without harsh ingredients.

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

This serum is unlikely to clog pores or cause breakouts for oily skin, as it has an excellent safety profile with soothing ingredients like birch sap and no harsh irritants. However, because it lacks specialized ingredients for controlling oily shine, oily skin often needs a product that includes oil-balancing or mattifying ingredients to fully manage excess oil.
Sources: [Archives of Dermatological Research, 2023](https://pubmed.ncbi.nlm.nih.gov/36961534/), [International Journal of Molecular Sciences, 2022](https://pubmed.ncbi.nlm.nih.gov/36293365/)

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

You can use this serum around the eyes, though the skin there is particularly thin. This product needs specialized ingredients to control oily shine and manage excess oil for oily skin.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/)

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

Yes, it has no fragrance and no drying alcohol.
