## Why this fit

- Offers moderate benefits for your oily skin, with Zinc PCA helping to regulate oil production and Glycerin providing essential hydration without clogging pores. The bio-mimicking peptides like sh-oligopeptide-2 and sh-oligopeptide-1 are excellent for firming and plumping, though they do not directly address the primary concern of reducing oily shine.
- The serum is formulated with soothing ingredients such as Panthenol and Glycerin, ensuring a gentle experience for your oily skin.
- This product is safe for your skin, as it contains no harsh ingredients and is free from irritants.

## 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/))
- A new topical panthenol-containing emollient significantly improved transepidermal water loss reduction, stratum corneum hydration, and intercellular lipid lamellae length compared with control in healthy subjects without negatively impacting bacterial viability. ([The Journal of Dermatological Treatment, 2017](https://pubmed.ncbi.nlm.nih.gov/27425824/))
- 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. ([American Journal of Clinical Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12113650/))
- A panthenol-enriched mask significantly decreased erythema and hyperpigmentation, increased sebum and stratum corneum moisture, and reduced transepidermal water loss compared to a saline dressing in 60 subjects undergoing facial laser treatment. ([Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40613435/))
- 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/))
- Mangifera indica extract-loaded green nanolipid carriers in topical emulsion amplified overall antioxidant effectiveness and antiaging activity compared to vehicle in human volunteers over three months. ([Biomedicines, 2022](https://pubmed.ncbi.nlm.nih.gov/36140367/))
- Mangifera indica extract reduced lipid production by 40% in sebocytes, improved sebum quality and quantity in Caucasian volunteers, reduced porphyrins expression, and decreased C. acnes lipase activity by 29% compared to placebo while protecting microbiota equilibrium. ([Molecules, 2022](https://pubmed.ncbi.nlm.nih.gov/35897945/))
- Mango butter-based foot care cream repaired worn and cracked skin in all human volunteers and exhibited a significant healing response in rat excision and incision wound models compared to untreated conditions. ([Indian Journal of Pharmaceutical Sciences, 2008](https://pubmed.ncbi.nlm.nih.gov/20046792/))

## Why other serums fit oily skin better

- Niacinamide and ferulic acid incorporated in a stable multiple emulsion successfully reduced melanin, sebum, and skin erythema while improving skin elasticity and hydration in human skin compared to a placebo. ([BioMed Research International, 2022](https://pubmed.ncbi.nlm.nih.gov/35342760/))

## What reviewers say

Users with mature, dry, or dull skin frequently praise this serum for its ability to visibly smooth fine lines and improve skin elasticity, often describing a "tightening" effect. While many appreciate its lightweight, hydrating texture and lack of irritation, a significant number of reviewers feel the high price tag is not justified by the results, and recent feedback suggests the product may be difficult to find or discontinued.

## How to apply

- 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.

This serum works moderately well for oily skin, helping to manage oil and add hydration without clogging pores, though other products fit this skin type better.
