This fit is calculated for the concerns frequently associated with combination skin: an oily T-zone, enlarged pores, and dry cheeks. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for combination skin; other serums fit it better.

## Why this fit

- Offers moderate treatment for your combination skin, as retinal helps minimize fine lines and niacinamide evens skin tone, while also providing hydration and soothing benefits supportive for oily shine.
- The presence of hyaluronic acid further aids in hydration, and niacinamide's seboregulation properties are beneficial for managing oiliness.
- The product is safe for your combination skin with no risks of irritation due to the absence of prohibited or harsh ingredients.

## What the research says

- 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/))
- 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/))
- Treatment with a combination of niacinamide and hyaluronic acid improved skin aging signs and demonstrated a senomorphic effect by decreasing SASP and autocrine signaling genes in women. ([Scientific Reports, 2024](https://pubmed.ncbi.nlm.nih.gov/39009698/))
- 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.

## Questions and answers

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

This treatment relies on ingredients like niacinamide and hyaluronic acid to provide balanced hydration without feeling heavy. To work best for this skin type, a product of this type needs effective ingredients like niacinamide, propolis, or zinc PCA that balance oil and boost radiance safely.

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

Retinal and niacinamide make this serum a good fit for combination skin because retinal helps smooth fine lines while niacinamide evens skin tone and helps manage oily shine. A treatment for this skin needs effective ingredients like niacinamide and propolis or zinc PCA that regulate oiliness and provide hydration without causing excess oiliness or dryness.

### What does Retinal do for combination skin?

Retinal helps smooth the skin and reduces signs of aging or breakouts when used regularly. It is unlikely to cause severe irritation when introduced gradually, keeping combination skin feeling calm and smooth.

### What does Niacinamide do for combination skin?

Niacinamide helps balance oily areas by reducing excess shine and pore size while keeping dry patches hydrated and smooth. It also works to calm redness and even out skin tone, making it very suitable for combination skin.
Sources: [The British Journal of Dermatology, 2002](https://pubmed.ncbi.nlm.nih.gov/12100180/), [Antioxidants, 2021](https://pubmed.ncbi.nlm.nih.gov/34439563/)

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

This treatment goes in the evening routine after cleansing and before moisturizing, which keeps things simple and safe around sun exposure. Combination skin works best with treatments that pair smoothing ingredients like retinal with soothing agents and lightweight hydrators to manage oily shine without drying.

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

You can use this serum with AHA by applying the AHA first and following with this treatment, though combination skin often needs products that balance oil and provide gentle hydration without overloading the skin.

### How often should I use this serum?

Use this treatment serum in your evening routine, starting just once a week to let your skin adjust safely. Combination skin of this type needs a balanced routine with gentle hydrating ingredients and oil control to manage both dry and oily areas effectively.

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

This serum is unlikely to clog pores or cause breakouts on combination skin, as it avoids heavy, pore-clogging ingredients. Retinal may cause some initial purging as it speeds up skin renewal, but the added niacinamide and ceramides help keep your skin calm and balanced.

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

Yes, it has no fragrance and no drying alcohol.
