This fit is calculated for the concerns frequently associated with dry sensitive skin: flakiness, tightness, redness, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

A great choice for dry sensitive skin; a few serums fit it even better.

## Why this fit

- Excellent suitability for your dry and sensitive skin due to the presence of glycerin and multiple peptides like copper tripeptide-1 and hexapeptide-11, which provide humectant action and support skin hydration and repair.
- The serum offers excellent plumping and firming benefits from peptides such as palmitoyl pentapeptide-4, addressing your dry or flaky skin concerns.
- The safety profile is high, with no risks of irritation for your dry and sensitive 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/))
- Topical palmitoyl pentapeptide (pal-KTTKS) provided significant improvement versus placebo control in the reduction of wrinkles and fine lines in Caucasian female subjects. ([International Journal of Cosmetic Science, 2005](https://pubmed.ncbi.nlm.nih.gov/18492182/))
- Combined therapy using a topical hyaluronic acid-niacinamide-Matrixyl serum and a multimodal facial device decreased TruSkin age by five years and reduced wrinkles more effectively than the serum alone in a 41-year-old woman with moderate facial aging over 12 weeks. ([Cureus, 2026](https://pubmed.ncbi.nlm.nih.gov/42500768/))
- Topical copper tripeptide complex on CO2 laser-resurfaced skin caused no significant reduction in erythema or objective improvement in wrinkles compared to controls, but significantly increased patient satisfaction regarding overall skin quality. ([Archives of Facial Plastic Surgery, 2006](https://pubmed.ncbi.nlm.nih.gov/16847171/))
- A novel regimen combining a hydroxy acid-based scrub and copper tripeptide serum significantly reduced adherent scalp flaking by 61.24%, increased hair density by 12.48%, increased hair thickness by 25.36%, and improved scalp skin hydration by 76.24% in adults with mild to moderate dandruff over 15 days. ([Cureus, 2024](https://pubmed.ncbi.nlm.nih.gov/39449909/))
- The combination of Thermus thermophilus and Bacillus subtilis mixed-culture ferment extract and copper tripeptide-1 GHK-Cu reduced inflammatory cytokines, protected skin explants from UV-induced damage, and improved wrinkles and skin barrier conditions compared to individual components or controls.

- Hexapeptide-11 activated proteasome, autophagy, chaperones, and antioxidant response genes, protected fibroblasts against oxidative-stress-mediated premature cellular senescence, and improved skin elasticity in human subjects. ([Redox Biology, 2015](https://pubmed.ncbi.nlm.nih.gov/25974626/))
- Hexapeptide-11 reversibly downregulated ATM and p53 protein expression in intrinsically aged fibroblasts, extrinsically aged fibroblasts, and extrinsically aged dermal papillae cells at concentrations between 0.1% and 1.0% in vitro, thereby influencing the onset of cellular senescence. ([Journal of Cosmetic Science, 2013](https://pubmed.ncbi.nlm.nih.gov/23578831/))
- Topical treatment with cyclized hexapeptide-9 significantly reduced wrinkles and roughness in crow's feet and forehead compared to vehicle, and generally outperformed retinol in healthy volunteers with aging skin.

- 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/))

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

## How to apply

- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.

### What does Hexapeptide-11 do for dry sensitive skin?

Hexapeptide-11 helps make dry, sensitive skin feel more firm and elastic by supporting its natural cellular repair and antioxidant defenses. Because it activates protective cell processes, it is unlikely to irritate easily, but dry skin of this type also needs rich soothing ingredients and gentle moisturizers to stay comfortable and smooth.
