The Lovi Fit is the same in every country; only the stores and prices differ, and the ones here are for Singapore.

Brand: [Youth To The People](https://lovi.care/skincare/sg/brands/youth-to-the-people)
Category: [Serums and treatments](https://lovi.care/skincare/sg/best/serums)

This fit is calculated for the concerns frequently associated with sensitive skin: redness, stinging, and reactions to new products. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for sensitive skin; other serums fit it better.

## Why this fit

- Offers moderate treatment for minimizing fine lines and wrinkles due to the presence of retinal in concentrations that promote skin renewal, which is beneficial for your normal skin type. Niacinamide and glycerin provide barrier repair and soothing effects, supporting your skin's overall health.
- While the product offers general hydration from squalane and soothing from niacinamide, which are supportive for your redness and irritation, it lacks specialized ingredients to directly address these concerns.
- The product is safe for your sensitive skin due to the absence of harsh ingredients and the inclusion of soothing components like niacinamide and glycerin.

## 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 post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin. ([Journal of Cosmetic Dermatology, 2021](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- 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/))
- Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance. ([Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12218231/))
- Topical 0.05% retinaldehyde applied over 1 year significantly increased epidermal thickness of the temple and cutaneous elasticity compared to an emollient control group in 40 aging skin patients. ([Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473959/))
- Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women. ([The Journal of Investigative Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging. ([Dermatologic Surgery, 2005](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- Topical 2% niacinamide significantly decreased sebum excretion rate in Japanese individuals and casual sebum levels in Caucasian individuals compared to placebo or baseline. ([Journal of Cosmetic and Laser Therapy, 2006](https://pubmed.ncbi.nlm.nih.gov/16766489/))
- Squalane at 0.005-0.015% counteracts UVA-induced oxidative stress, inflammation, and collagen metabolism inhibition while stimulating fibroblast migration in human dermal fibroblasts. ([Molecules, 2025](https://pubmed.ncbi.nlm.nih.gov/40363772/))
- Plant-derived squalane protected human dermal fibroblasts against UVA-induced damage by counteracting ROS formation, suppressing apoptosis-related proteins p53, caspase-3, caspase-9, and PARP, and restoring the pro-survival p-Akt/mTOR pathway. ([Antioxidants, 2025](https://pubmed.ncbi.nlm.nih.gov/40722956/))

## Why other serums fit sensitive skin better

- Topical application of TAT-SOD significantly suppresses UVB-induced erythema formation, blood flow rise, and apoptotic sunburn cell formation in human volunteers compared to a vehicle control.

## Questions and answers

### How well does Youth To The People Retinal + Niacinamide Youth Serum work for sensitive skin?

Youth To The People Retinal + Niacinamide Youth Serum works moderately well for sensitive skin, offering safe skin renewal and soothing benefits, though other options fit this skin type better. A product of this type needs specialized ingredients that directly target redness and irritation with exceptional suitability and high compatibility.

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

This serum works for sensitive skin because it includes niacinamide and glycerin, which help calm and keep the skin comfortable. To be a better fit for this skin, a treatment of this type needs targeted ingredients that actively soothe redness and irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Retinal do for sensitive skin?

Retinal helps smooth fine lines, improve texture, and even out skin tone while generally maintaining a good tolerance profile with a lower likelihood of irritation compared to stronger forms of vitamin A.
Sources: [Journal of Drugs in Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/39496127/), [Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473963/)

### What does Niacinamide do for sensitive skin?

Niacinamide helps calm sensitive skin by strengthening the skin barrier and reducing redness and irritation. It is very well tolerated and may improve overall comfort and resilience with regular use.
Sources: [Cutis, 2005](https://pubmed.ncbi.nlm.nih.gov/16209160/), [Journal of Cosmetic Dermatology, 2004](https://pubmed.ncbi.nlm.nih.gov/17147561/)

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

This serum goes in the evening routine. This product needs calming extracts, extra hydrators, and barrier-repairing ceramides to properly care for sensitive skin.

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

You can use this serum with AHAs, but it is best to use them on alternating nights rather than at the same time to avoid overwhelming your skin. Using strong exfoliants and retinal together can easily lead to redness and irritation, so a product for this skin needs extra soothing and barrier-repairing ingredients like ceramides and squalane.

### How often should I use this serum?

This treatment serum works well in an evening routine, and you can start by applying it once a week to see how your skin tolerates it. This type of product needs extra soothing ingredients, barrier-repairing ceramides, and gentle hydrators to keep sensitive skin calm and comfortable.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This serum may cause temporary dryness and flaking as it helps renew your skin, but it is unlikely to harm sensitive skin thanks to its soothing ingredients. A product of this type for sensitive skin needs extra calming ingredients and deep hydration to keep skin smooth and comfortable without irritation.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Yes, it has no fragrance and no drying alcohol.
