Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate hydration for your combination skin, as sodium hyaluronate and seaweed extracts like Gigartina Skottsbergii Extract provide humectant and potential anti-inflammatory benefits.
- While beneficial for general skin health, these ingredients do not directly address your primary concerns of acne, blemishes, and breakouts.
- The product is safe for your combination skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.
How to apply
- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help keep breakouts under control.
- Apply after your cleanser and toner, and make sure to use your SPF right after in the morning.
- Gently spread a small amount of moisturizer over your face using soft motions. Let it absorb into the skin for a minute before getting dressed or applying makeup.
- Apply on slightly damp skin to help lock in extra moisture. This keeps your combination skin balanced without feeling heavy.
- Avoid the eye area and do a patch test before your first use. Stop using if you feel any irritation.
