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 due to the humectant action of glycerin and hyaluronic acid, which support skin hydration, but these ingredients offer general skincare benefits that are mostly supportive and irrelevant for your main goal of pigmentation.
- Acetyl hexapeptide-8 and palmitoyl tripeptide-1 provide moderate plumping by improving volume and elasticity, which is a secondary benefit for your skin concerns.
- The product is safe for your normal skin, with no risks of irritation 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/))
- Chronomodulated daytime application of baicalin and nighttime application of palmitoyl tripeptide-1 synergistically improved skin luminance by 16.29%, nasolabial fold depth by -36.35%, and firmness by 24.35% in 30 female participants. ([Journal of Cosmetic Dermatology, 2026](https://pubmed.ncbi.nlm.nih.gov/41527525/))
- 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/))
- 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/))
- Palmitoyl tetrapeptide-7, acetyl hexapeptide-8, palmitoyl tripeptide-1, and palmitoyl tetrapeptide-10 significantly increased type III collagen levels in human dermal fibroblasts following UV exposure, with their combination demonstrating a greater effect in vitro and enhancing type I, III, and IV collagen levels in ex vivo skin tissues compared to individual components. ([International Journal of Cosmetic Science, 2026](https://pubmed.ncbi.nlm.nih.gov/42683869/))

## 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/))
