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

Works for mature skin; other serums fit it better.

## Why this fit

- Offers moderate rejuvenation for your normal skin, as retinal and palmitoyl tripeptide-38 work to minimize fine lines and wrinkles, while niacinamide and sodium hyaluronate provide supportive hydration and soothing benefits.
- The formula is highly suitable for normal skin due to the presence of niacinamide and retinal, which help regulate sebum and skin cell turnover.
- The product has a good safety profile with no risks of irritation for your normal skin, as it lacks prohibited or harsh ingredients.

- Over-the-counter retinol products provided only weak evidence for a mild ameliorating effect on fine facial skin wrinkle lines in randomized, double-blind, vehicle-controlled trials, and major methodological flaws call the validity of positive results into question. ([The Journal of Clinical and Aesthetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/34980969/))
- A cosmetic niacinamide/peptide/retinyl propionate regimen significantly improved periorbital wrinkle appearance relative to a 0.02% tretinoin regimen at 8 weeks with comparable benefits at 24 weeks, while demonstrating significantly better tolerability in 196 women. ([The British Journal of Dermatology, 2010](https://pubmed.ncbi.nlm.nih.gov/20374604/))
- A novel triple-active cosmetic formulation containing 4-hexylresorcinol, retinyl propionate, and niacinamide improved the visual appearance of photoageing similarly to 0.02% tretinoin and reversed a consensus gene signature associated with ageing in female adults while causing less skin irritation. ([International Journal of Cosmetic Science, 2024](https://pubmed.ncbi.nlm.nih.gov/38685700/))

- Twice daily application of retinaldehyde 0.1% and 0.05% creams for 3 months improved skin texture and hydration and reduced transepidermal water loss in 40 female Korean volunteers, with only the 0.1% cream significantly improving the melanin index. ([Journal of Cosmetic Dermatology, 2018](https://pubmed.ncbi.nlm.nih.gov/29663701/))
