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

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

## Why this fit

- Offers moderate firming for your oily skin due to Tetrapeptide-21 and Palmitoyl Tripeptide-1 Acetate, which promote elasticity and reduce fine lines, while Aminopropyl Ascorbyl Phosphate and Glycerin provide antioxidant and humectant benefits. This formula is highly suitable for oily skin and generally safe, lacking harsh ingredients and including soothing agents like Sodium Hyaluronate.
- While it provides general hydration and antioxidant support, the formula lacks targeted ingredients to address your primary concerns of acne, blemishes, and breakouts.
- 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.

([Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/))

([Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/))
- A multi-modal methodology combining MALDI-MSI, in vivo RCM, echography, and histology revealed age-related decreases in extracellular matrix and epidermal-dermal junction proteins and undulation depth, while a blend of palmitoyl oligopeptide and palmitoyl tetrapeptide-7 improved subepidermal low-echogenic band thickness, density, and extracellular matrix structure compared to placebo. ([Journal of Cosmetic Dermatology, 2015](https://pubmed.ncbi.nlm.nih.gov/25817264/))

- 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/))

## Questions and answers

### How well does Bio Serum Firm work for oily acne-prone skin?

This serum works moderately well for your oily skin by offering firming benefits and hydration, though other products fit it better because it lacks targeted ingredients for acne and breakouts. An oily acne-prone skin needs a product with ingredients like niacinamide, propolis, or Vitamin C that control excess oil and target blemishes without causing breakouts.
Sources: [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum works for your oily skin because it contains peptides and growth factors that firm the skin, along with sodium hyaluronate and glycerin for hydration. It also has vitamin C derivatives for antioxidant support, though treatments that rate higher for acne-prone skin need targeted ingredients like niacinamide and propolis to control excess oil and clear breakouts.
Sources: [Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Growth Factor do for oily acne-prone skin?

Growth Factor helps reduce both red, inflamed spots and clogged pores on oily, acne-prone skin. Studies show it supports skin repair and improves acne lesions over several weeks of regular use.
Sources: [International Journal of Dermatology, 2014](https://pubmed.ncbi.nlm.nih.gov/24962549/)

### What do Peptides do for oily acne-prone skin?

Peptides help calm oily, acne-prone skin by targeting acne-causing bacteria and reducing redness and swelling. Advanced delivery methods like nanomicelles may also improve how deeply these helpful ingredients sink into the skin.
Sources: [Advanced Science, 2025](https://pubmed.ncbi.nlm.nih.gov/39783908/), [Bioorganic Chemistry, 2025](https://pubmed.ncbi.nlm.nih.gov/40925226/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, which keeps application simple and safe around sun exposure. While it provides good firming and hydration, this skin type needs targeted ingredients like salicylic acid or niacinamide to address breakouts.

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

You can use this serum with retinol by applying the serum first and following with your retinol after it absorbs. This formula lacks harsh ingredients and is unlikely to irritate oily skin, but to treat acne effectively, it needs targeted ingredients like salicylic acid or benzoyl peroxide.

### How often should I use this serum?

This treatment is used in the evening, applying it once a day for your oily skin. Oily and acne-prone skin of this type needs acne-fighting ingredients like salicylic acid, benzoyl peroxide, or retinoids to clear breakouts and prevent blemishes.

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

This serum is unlikely to clog pores or cause breakouts on oily skin, as it has a very safe formula with soothing ingredients and no harsh irritants. However, because it lacks targeted ingredients for acne and blemishes, oily acne-prone skin needs a product that includes acne-fighting and oil-controlling ingredients like salicylic acid or niacinamide.

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

Yes, it has no fragrance and no drying alcohol.
