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 moisturizers fit it better.

## Why this fit

- Offers moderate moisturizing for your normal skin due to the humectant action of glycerin, which hydrates and plumps the skin. However, this product does not directly address your primary concern of wrinkles and fine lines.
- While glycerin provides basic hydration, the formula lacks ingredients specifically targeted to improve the appearance of wrinkles and fine lines.
- The product is safe for your normal skin, as it contains no harsh or prohibited ingredients that would cause irritation.

## 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/))
- The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol. ([Journal of Cosmetic Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/31532576/))
- Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant. ([International Journal of Cosmetic Science, 2001](https://pubmed.ncbi.nlm.nih.gov/18498456/))
- Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects. ([Journal of Drugs in Dermatology, 2012](https://pubmed.ncbi.nlm.nih.gov/22206073/))
- Wearing an N95 mask alone compared to using dimethicone cream or hydrocolloid dressing caused more adverse skin reactions among 73 military health care workers, with no significant differences in fit test failure rates between groups. ([Military Medicine, 2024](https://pubmed.ncbi.nlm.nih.gov/38771104/))
- A dimethicone skin protectant lotion significantly decreased visual scoring and transepidermal water loss compared to vehicle control and SLS-only treated sites in 12 healthy humans exposed to sodium lauryl sulfate. ([Skin Research and Technology, 2000](https://pubmed.ncbi.nlm.nih.gov/11428946/))
- Treatment with a moisturizer containing dimethicone and glycerine increased epidermal thickness by 0.019 mm, improved barrier function by decreasing transepidermal water loss by 13%, decreased melanin intensity, and induced keratins 6 and 16 in fifteen women with moderately photoaged forearms. ([Clinical and Experimental Dermatology, 2007](https://pubmed.ncbi.nlm.nih.gov/17137484/))

## Why other moisturizers fit mature skin better

- Topical application of Lactobacillus plantarum-GMNL6 enhanced collagen synthesis and SPTSSA gene expression while reducing melanin synthesis, Staphylococcus aureus biofilm, and Cutibacterium acnes proliferation, leading to clinical improvements in skin moisture, color, spots, wrinkles, UV spots, and porphyrins in human volunteers. ([International Journal of Medical Sciences, 2021](https://pubmed.ncbi.nlm.nih.gov/33526970/))
- Nanoemulsions containing Macadamia integrifolia seed oil successfully enhanced skin hydration and reduced wrinkles in human volunteers, outperforming conventional emulsions in skin hydration enhancement. ([Nanomaterials, 2024](https://pubmed.ncbi.nlm.nih.gov/38668218/))
- 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/))

## What reviewers say

Based on a very large amount of data, users frequently report achieving a "glass skin" radiance and noticeably smoother texture, with many praising its ability to soften fine dynamic lines around the eyes and forehead. While effective for most, results vary on deeper, etched-in wrinkles, and some users with sensitive skin experienced minor irritation or found the high price point unjustifiable for the subtle changes observed.

- Liked: Improves skin texture (mostly mentioned)
- Liked: Enhances radiance (often mentioned)
- Liked: Lightweight absorption (often mentioned)
- Disliked: High price point (often mentioned)
- Liked: Reduces fine lines (sometimes noted)
- Disliked: Lack of results (sometimes noted)
- Disliked: Skin irritation (rarely noted)
- Disliked: Sticky texture (rarely noted)

## How to apply

- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help smooth fine lines.
- Apply this product after your toner and serum, but before your SPF in the morning. Follow your cleanser and toner steps to keep your skin balanced.
- Gently press a small amount into your face and neck. Avoid rubbing the skin too harshly to prevent extra tension.
- Apply the moisturizer on slightly damp skin to help lock in extra moisture. Clean skin helps the product absorb much more evenly.
- Avoid the sensitive eye area during application. Do a quick patch test before your very first use to stay safe.

## Questions and answers

### How well does SkinCeuticals P-Tiox work for mature skin?

SkinCeuticals P-Tiox works moderately well for mature skin, as it provides basic hydration through glycerin but does not directly address wrinkles and fine lines. A product of this type needs potent ingredients like peptides and antioxidants, along with a rich blend of emollients and humectants, to effectively smooth wrinkles and maintain moisture balance in mature skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This moisturizer provides basic hydration for mature skin through glycerin, but it does not contain the specialized ingredients needed to reduce wrinkles and fine lines. To truly fit mature skin, a product needs potent anti-aging ingredients like peptides, antioxidants, and soothing components, alongside a rich blend of hydrators to smooth and nourish the skin.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### What does Water do for mature skin?

Water helps keep mature skin hydrated, which significantly lowers the severity of wrinkles and maintains elasticity. Because aging skin often loses moisture and firmness, it needs hydrating ingredients like glycerin and hyaluronic acid to stay plump and smooth.
Sources: [Skin Research and Technology, 2013](https://pubmed.ncbi.nlm.nih.gov/22672420/)

### What does Glycerin do for mature skin?

Glycerin helps keep mature skin feeling soft and smooth by drawing moisture into the outer layer and locking it in. This daily hydration boost supports the skin barrier, keeping dry areas comfortable and protected against irritation.
Sources: [The British Journal of Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/18510666/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

SkinCeuticals P-Tiox is a moisturizer that goes after your hydrating toner in the morning and after your treatment step at night. Because this product offers only moderate hydration and lacks ingredients specifically targeted for wrinkles and fine lines, mature skin needs a product of this type that also includes powerful anti-aging actives and nourishing peptides to truly smooth and firm the skin.

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

You can use this moisturizer with retinol by applying the moisturizer after your retinol treatment to help soothe your skin and keep it soft. Using a moisturizer with retinol is unlikely to cause irritation and helps your skin adjust to active treatments.
Sources: [Cutis, 2006](https://pubmed.ncbi.nlm.nih.gov/17121065/)

### How often should I use this serum?

This product is a moisturizer, so you can use it in your morning and evening routines. It provides basic hydration, but mature skin also needs targeted ingredients specifically formulated to smooth wrinkles and fine lines.
Sources: [Health Science Reports, 2021](https://pubmed.ncbi.nlm.nih.gov/34141902/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

This moisturizer is unlikely to clog pores or cause breakouts for mature skin, as it is safe and free of harsh ingredients that typically cause irritation. However, a product of this type needs targeted ingredients like peptides or retinoids to properly smooth out wrinkles and fine lines on mature skin.

### Can I use this serum around the eyes or on my body?

This moisturizer is safe to use around the eyes and on the body because it contains gentle ingredients that are unlikely to cause irritation. However, mature skin needs targeted anti-aging ingredients like hyaluronic acid, peptides, or botanical extracts to effectively smooth wrinkles and fine lines in delicate areas.
Sources: [Surgical and Radiologic Anatomy, 2002](https://pubmed.ncbi.nlm.nih.gov/12375070/), [Polymers, 2023](https://pubmed.ncbi.nlm.nih.gov/37896378/)

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

Yes, it has no fragrance and no drying alcohol.
