This fit is calculated for the concerns frequently associated with dark spots: hyperpigmentation, sun spots, and uneven skin tone. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for skin with dark spots; other serums fit it better.

## Why this fit

- Suitable for normal skin, this serum utilizes Glycerin and Sodium Hyaluronate for hydration and peptides like Acetyl Octapeptide-3 and Acetyl Hexapeptide-8 to support skin structure and provide moderate plumping.
- While it offers general skincare benefits, the formulation does not specifically target your main concern of pigmentation.
- The safety profile is excellent, with no risks of irritation for your normal skin due to the absence of prohibited or harsh ingredients.

## 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/))
- Argireline treatment twice daily for 4 weeks produced a significant anti-wrinkle effect with 48.9% total efficacy and decreased skin roughness in Chinese subjects compared with 0% efficacy and no decrease in roughness in the placebo group. ([American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/))
- Treatment with cross-linked hyaluronic acid-based microneedle patches combined with acetyl hexapeptide-8 or epidermal growth factor significantly improved wrinkles and skin hydration compared to the patch alone in Korean females over 29 days. ([Annals of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/33911590/))
- Acetyl hexapeptide-3 and tripeptide-10 citrulline demonstrated antiwrinkle efficacy and decreased transepidermal water loss in twenty-four healthy volunteers compared to control groups, though synergistic effects between the two peptides remained unclear. ([Journal of Cosmetic Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28150423/))
- Daily topical acetyl hexapeptide-8 showed a trend toward a longer time until return to baseline Jankovic Blepharospasm Rating Scale scores compared to placebo (3.7 months vs. 3.0 months) in 24 patients with blepharospasm receiving botulinum toxin therapy. ([European Journal of Neurology, 2013](https://pubmed.ncbi.nlm.nih.gov/23146065/))
- Argireline applied twice daily for 4 weeks achieved a total anti-wrinkle efficiency of 48.9% and notably reduced wrinkle depth compared to placebo in Chinese subjects. ([Journal of Cosmetic and Laser Therapy, 2013](https://pubmed.ncbi.nlm.nih.gov/23607739/))
- 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/))
- Application of a cosmetic multiple emulsion containing vitamin C and wheat protein as well as a base formulation increased skin moisture in 11 human volunteers over four weeks, while producing no significant variations in skin sebum, pH, elasticity, melanin, or erythema. ([Pakistan Journal of Pharmaceutical Sciences, 2008](https://pubmed.ncbi.nlm.nih.gov/18166519/))
- The addition of polymers and hydrolysed proteins to model body wash cosmetics improves foaming properties, storage stability, and safety by reducing skin irritant potential, with the polyvinylpyrrolidone/hydrolysed wheat protein crosspolymer showing the strongest reduction effect. ([Colloids and Surfaces. B, Biointerfaces, 2015](https://pubmed.ncbi.nlm.nih.gov/26291586/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([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/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))

## Why other serums fit skin with dark spots better

- Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer. ([The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Treatment with 14% ferulic acid and 12% l-ascorbic acid significantly reduced pigmentation and erythema while improving hydration and elasticity in 20 women with photoaged skin, with neither acid proving definitively more effective overall though ascorbic acid showed slightly greater skin lightening. ([Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/34877760/))

## Questions and answers

### How well does ExLinea Pro Peptide Serum work for skin with dark spots?

This serum works for your skin, though other products fit it better because its formula does not specifically target dark spots. A product for this skin needs effective antioxidants and soothing ingredients that fade pigmentation without causing irritation, while still keeping normal skin hydrated and supported.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [American Journal of Clinical Dermatology, 2013](https://pubmed.ncbi.nlm.nih.gov/23417317/)

### Which ingredients make this serum a good fit for skin with dark spots?

This serum works for skin with dark spots because it contains glycerin and sodium hyaluronate to keep skin hydrated and plump. However, a product fit for this skin needs effective antioxidants and soothing ingredients like niacinamide and propolis to specifically target pigmentation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Acetyl Octapeptide-3 do for skin with dark spots?

Acetyl octapeptide-3 is commonly included in anti-aging formulas to help smooth fine lines and address skin concerns like dark spots by targeting muscle contractions and supporting a more even skin tone. This ingredient may help improve overall skin texture, but skin with dark spots also benefits from brightening ingredients like niacinamide and vitamin C to effectively fade discoloration.

### What does Argireline do for skin with dark spots?

Argireline is not known to do anything for dark spots on the skin. It is used to help smooth lines and reduce skin roughness by targeting facial wrinkles.

### Where does this serum go in a skincare routine for skin with dark spots?

This serum goes in the evening routine, after cleansing and before moisturizing, though skin with dark spots also needs targeted brightening ingredients like vitamin C or retinoids.

### 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 support your skin, followed by your retinol. This approach helps minimize potential dryness while allowing both products to work effectively.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### How often should I use this serum?

You can use this treatment in the evening as part of your routine. It is unlikely to cause irritation on normal skin, but skin with dark spots needs a product with targeted brightening ingredients.

### Can this serum clog pores, cause breakouts or purging for skin with dark spots?

This serum is unlikely to clog pores or cause breakouts for your skin with dark spots because it has a very safe formula with no harsh or heavy ingredients. However, because it does not target dark spots, this skin type needs a product that specifically focuses on brightening ingredients to fade discoloration.

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

Yes, it has no fragrance and no drying alcohol.
