Lovi Assistant explains

Questions and answers
How well does Medik8 Crystal Retinal 3 work for combination skin?
Medik8 CRYSTAL RETINAL 3 works reasonably well for combination skin, offering moderate benefits since retinaldehyde and hyaluronic acid help control oily shine and provide hydration. Glycerin and squalane add nourishment while supporting overall skin health without causing irritation. However, combination skin often needs ingredients like niacinamide, zinc PCA, and propolis to better balance oiliness and enhance radiance.
Which ingredients make this serum a good fit for combination skin?
Retinaldehyde and hyaluronic acid make this serum a good fit for combination skin because they help regulate skin renewal and provide hydration that can manage oily shine. Glycerin and squalane add further nourishment and hydration, while the safe formula is unlikely to cause irritation. To fit combination skin even better, a treatment of this type needs ingredients like niacinamide, propolis, or zinc PCA to enhance radiance and better control oiliness.
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.
European Review for Medical and Pharmacological Sciences, 2014Journal of Cosmetic Dermatology, 2011
What does Hyaluronic Acid do for combination skin?
Hyaluronic acid is a great fit for combination skin because it quenches dry areas with a boost of hydration while keeping oily zones balanced. Regular use helps smooth out fine lines and makes your skin feel soft and plump without causing irritation.
Dermatology and Therapy, 2021Journal of Drugs in Dermatology, 2011
Where does this serum go in a skincare routine for combination skin?
This treatment goes in the evening routine after cleansing and toning, and before moisturizing. A product for combination skin needs ingredients like retinaldehyde and hyaluronic acid to help manage oily shine while providing hydration.
Can I use this serum with niacinamide, and in what order?
You can use this treatment with niacinamide by applying niacinamide first to keep your skin calm and hydrated, followed by this product. This type of skin also needs ingredients like ceramides and soothing botanical extracts to balance oil and moisture without irritation.
How often should I use this serum?
Use this treatment in your evening routine, starting once a week to see how your combination skin tolerates it before considering more frequent use. This product of this type needs ingredients like retinoids and hyaluronic acid to help manage oily shine while keeping the skin hydrated.
Can this serum clog pores, cause breakouts or purging for combination skin?
Medik8 CRYSTAL RETINAL 3 is unlikely to clog pores or cause breakouts on combination skin, though you may experience mild dryness or purging as your skin adjusts to the retinaldehyde. This treatment helps regulate skin renewal and provides balanced hydration, but a product for combination skin needs lightweight hydrators and pore-clearing ingredients that won't feel heavy on oily areas.
Is this serum fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
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, 2017Twice 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, 2018Topical retinaldehyde demonstrated significant antibacterial activity against gram-positive bacteria both in vitro and in vivo, leading to decreased bacterial counts without inducing resistance.

Antioxidants, 2025The 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.
