Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate moisturizing for your combination skin due to glycerin's humectant properties, but lacks ingredients to specifically target oily shine, potentially exacerbating this concern.
- Dimethicone provides emollient benefits, which are generally suitable for combination skin, but the overall formula's focus on hydration may not sufficiently address your primary goal of reducing oiliness.
How to apply
- Use this moisturizer in your AM and PM routine every day to control shine. Always pair with SPF in the morning.
- Apply this moisturizer after your cleanser and toner, right before your morning SPF.
- Gently press a small amount of the moisturizer into your skin and avoid harsh rubbing. Let it ⏳absorb for a minute.
- Apply the moisturizer on slightly damp skin to help it lock in moisture better. This keeps your combination skin balanced.
- Avoid the eye area when applying the moisturizer. Do a patch test before your first use.
People Say
★4.5Overall rating based on 3.1k+ reviewsBased 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.

Questions and answers
Why does Lovi advise caution with SkinCeuticals P-Tiox for combination skin?
Lovi advises caution because this moisturizer offers moderate hydration with glycerin and dimethicone, but it lacks ingredients to specifically target oily shine and may exacerbate this concern. A product of this type needs effective brightening and moisturizing ingredients, soothing agents, and antioxidants that target hydration and brightness while reducing oily shine without irritation.
Which ingredients make this serum a poor fit for combination skin?
This moisturizer is a poor fit because glycerin provides moderate moisture but lacks ingredients to target oily shine, and dimethicone's feel may not suit your skin. A better choice for combination skin needs effective brightening and moisturizing ingredients to reduce oily shine without irritation, along with soothing agents, antioxidants, multiple peptides, and a balanced pH that delivers hydration without excess oil.
What does Water do for combination skin?
Water helps keep combination skin hydrated, though a product of this type needs additional barrier-protecting ingredients like ceramides or petrolatum to lock in that moisture and support overall skin health.
What does Glycerin do for combination skin?
Glycerin helps keep combination skin soft and smooth by pulling moisture in and keeping it there. It improves hydration and supports your skin barrier, which is unlikely to cause irritation.
The British Journal of Dermatology, 2008Clinical, Cosmetic and Investigational Dermatology, 2017
Where does it go in a skincare routine for combination skin?
This moisturizer fits in the morning routine after your hydrating toner and before your sunscreen, and in the evening routine as your final step. Combination skin needs products with ingredients that balance hydration without adding oily shine.
Can I use it with retinol, and in what order?
This moisturizer is a poor match for your combination skin and may increase oily shine while you use retinol, as it lacks ingredients to balance oil. Combination skin needs lightweight hydrators and oil-controlling ingredients like niacinamide or salicylic acid to stay clear and comfortable when using retinol.
How often should I use it?
This moisturizer is a poor match for your combination skin and may increase oily shine, so use a product of this type that helps control oil while keeping skin soft.
Can it clog pores, cause breakouts or purging for combination skin?
SkinCeuticals P-Tiox is unlikely to directly cause breakouts, but its heavy focus on moisture may worsen oily shine on combination skin. A product for this skin needs ingredients that help balance oil and keep pores clear while providing light hydration.
Can I use it around the eyes or on my body?
You can use this moisturizer around your eyes and on your body, but it is a poor match for your combination skin because it lacks ingredients to control oily shine. A product for this skin needs oil-balancing ingredients to keep the face looking fresh.
Is it fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
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, 2017Petrolatum-based skin protectants demonstrated protection against irritants and maceration while providing skin hydration, whereas dimethicone and zinc oxide products showed varying or limited performance across parameters among 18 healthy volunteers compared to positive and negative controls.
Ostomy/wound Management, 2005The 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, 2020Ten 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, 2001Niacinamide/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, 2012Wearing 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, 2024A 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, 2000Treatment 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.
