Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate suitability for your oily skin, as Saccharomyces Rice Ferment Filtrate and Glycerin provide humectant action to hydrate and plump, but it lacks sufficient seboregulating components for optimal oil control.
- While it offers excellent moisturizing due to Glycerin and Sodium Hyaluronate, its benefits are mostly supportive and irrelevant for addressing your oily shine.
- The product is generally safe for your oily skin, with minimal risks of irritation from alcohol and fragrance.
How to apply
- Could be used as part of your AM or PM routine every day to keep your face fresh.
- Apply this moisturizer after cleansing and toning, but right before your SPF in the morning.
- Gently press a small amount into your skin and let it absorb fully.
- Apply on clean, slightly dry skin to help control that oily shine.
- Avoid the eye area and do a quick patch test before your first use.

Questions and answers
How well does The Dewy Serum work for oily skin?
This serum works moderately well for oily skin, as it provides hydration with glycerin and rice ferment filtrate, but it lacks enough oil-controlling ingredients for your shine. Oily skin of this type needs a formula with niacinamide to help balance oil production and green tea extract to soothe without feeling heavy.
