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 serums fit it better.

## Why this fit

- Guaiazulene provides soothing benefits, and the absence of harsh ingredients ensures a gentle experience for your oily skin.
- The product is safe for your oily skin, with no risks of irritation and the inclusion of soothing agents.

## What the research says

- Bovine basic fibroblast growth factor combined with ultrapulsed fractional CO2 laser increased the overall response rate, reduced ECCA scores, scar base depth, skin pore value, texture value, transepidermal water loss, redness duration, scabbing duration, erythema duration, and adverse reactions, while increasing skin water and epidermal oil content in patients with acne scars compared to ultrapulsed fractional CO2 laser therapy alone. ([Clinical, Cosmetic and Investigational Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37841061/))
- Pterostilbene at 20 μM protected HaCaT keratinocytes from particulate matter-induced damage by reducing intracellular ROS, inhibiting AHR nuclear translocation, suppressing inflammation and aging protein cascades, and rescuing moisturizing protein expression. ([Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34679686/))
- Topical epidermal growth factor combined with silver sulfadiazine accelerated the rate of epidermal regeneration and significantly decreased healing time by approximately 1 to 1.5 days across all stages of healing in skin-graft-donor sites of 12 patients compared to silver sulfadiazine alone. ([The New England Journal of Medicine, 1989](https://pubmed.ncbi.nlm.nih.gov/2659995/))
- Topical recombinant human epidermal growth factor combined with ablative fractional carbon dioxide laser significantly improved striae surface texture and showed significantly greater participant satisfaction regarding marked improvement compared to ablative fractional carbon dioxide laser combined with Aloe vera gel in patients with striae alba. ([Lasers in Surgery and Medicine, 2020](https://pubmed.ncbi.nlm.nih.gov/30614013/))
- Topical EGF combined with fractional CO2 laser significantly improves the clinical appearance of atrophic acne scars and decreases skin pigmentation compared to fractional CO2 laser alone in patients with atrophic acne scars. ([The Journal of Clinical and Aesthetic Dermatology, 2022](https://pubmed.ncbi.nlm.nih.gov/35942017/))
- Topical application of PTD-EGF and FGF1 increased cell proliferation and collagen accumulation while protecting against UV-induced damage and improving wrinkle parameters in human skin. ([Journal of Cosmetic Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/24305427/))
- Basic fibroblast growth factor-loaded human serum albumin nanoparticles enhanced the proliferation and migration of human dermal fibroblasts, down-regulated myofibroblast-related genes, and accelerated wound healing with enhanced angiogenesis in vivo compared to unstable native forms. ([Journal of Nanobiotechnology, 2023](https://pubmed.ncbi.nlm.nih.gov/37658367/))
- Topical application of basic fibroblast growth factor decreases elevated transepidermal water loss and increases Ki67 expression in keratinocytes following mechanical scratching in a mouse model. ([Skin Pharmacology and Physiology, 2013](https://pubmed.ncbi.nlm.nih.gov/23108135/))
- Applying a topical product containing blueberry extract and Pro-xylane following micro-focused ultrasound significantly improved global aesthetic improvement, skin elasticity, and fine lines compared to standard moisturizer in 50 patients. ([Journal of Cosmetic Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40635529/))
- Topical usage of blueberries may prevent skin damage from environmental stressors by inducing an active skin response against noxious effects. ([Antioxidants, 2023](https://pubmed.ncbi.nlm.nih.gov/37371992/))
- Pretreatment with blueberry extracts prevented ozone-induced ROS production, NLRP1-ASC scaffold formation, and CASP1 and IL-18 transcripts across 2D, 3D, and human skin explant models. ([Oxidative Medicine and Cellular Longevity, 2020](https://pubmed.ncbi.nlm.nih.gov/32855770/))

## Why other serums fit oily skin better

- A panthenol-enriched mask improved skin hydration, regulated sebum, and reduced redness and TEWL across dry sensitive, oily sensitive, and oily acne skin subgroups with excellent tolerance and no adverse reactions. ([Journal of Cosmetic Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/38366684/))
- 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/))

## How to apply

- Use this serum in your PM routine. Start by applying it 3 times a week and build up to daily use if your skin tolerates it well.
- 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.

## Questions and answers

### How well does the Midnight Blue Youth Activating Drop work for oily skin?

This treatment works for oily skin by helping soothe and rejuvenate it safely, but it lacks oil control. A product of this type needs ingredients like niacinamide, zinc PCA, and ferulic acid to manage excess oil and shine.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37841061/)

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

This serum works for oily skin because it contains soothing guaiazulene and peptides that help renew the skin gently. However, because it lacks oil-controlling ingredients, an oily skin type needs a product that includes sebum-regulating ingredients like niacinamide, zinc PCA, or ferulic acid.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2023](https://pubmed.ncbi.nlm.nih.gov/37841061/)

### What does EGF do for oily skin?

Epidermal growth factor helps improve skin texture and supports overall barrier function for oily skin. When used in serums, it is generally well-tolerated and helps keep the skin smooth and balanced.
Sources: [Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22527430/), [Gels, 2025](https://pubmed.ncbi.nlm.nih.gov/41294565/)

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

This treatment goes in the evening routine after cleansing and before your moisturizer. Oily skin also needs specialized ingredients for oil control.

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

You can use this treatment alongside retinol by applying the treatment after your toner and before your moisturizer in your evening routine. It is unlikely to cause irritation on oily skin, but this skin type also needs specialized ingredients for oil control.

### How often should I use this serum?

This treatment works well in the evening routine, where it helps rejuvenate oily skin with a gentle and safe experience. Because this product type lacks oil control, oily skin needs specialized ingredients that balance oil production alongside this serum.

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

This serum is unlikely to clog pores, cause breakouts, or lead to purging on oily skin, as it has a very gentle formula with no harsh ingredients. However, because it lacks oil-controlling ingredients, oily skin may still need additional products that help balance oil and shine.

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

Yes, it has no fragrance and no drying alcohol.
