Lovi Assistant explains
- Excellent suitability for your combination skin and acne concerns is provided by Camellia Sinensis Leaf Extract and Epigallocatechin Gallate, which offer potent antioxidant and anti-inflammatory benefits to calm blemishes and regulate oil production.
- Niacinamide and Panthenol further enhance hydration and skin tone, supporting overall skin health without compromising your non-sensitive skin.
- The formulation is safe for your skin, featuring soothing ingredients and avoiding harsh components.
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.

Niacinamide and panthenol further boost hydration and support overall skin health without clogging pores. The safe, gentle formula avoids harsh components to keep your skin smooth and calm.
Which ingredients make this serum a good fit for acne-prone skin?
Camellia Sinensis Leaf Extract and Epigallocatechin Gallate make this serum a great fit for acne-prone skin because they calm blemishes and regulate oil production. Niacinamide and Panthenol also support overall skin health by enhancing hydration.
What does Green Tea Extract do for acne-prone skin?
Green tea extract helps calm red, angry breakouts and controls extra oil when applied to acne-prone skin. It reduces both pimples and oily shine because its natural plant compounds soothe swelling and balance sebum production.
What does Niacinamide do for acne-prone skin?
Niacinamide helps acne-prone skin by reducing both inflamed and uninflamed breakouts and calming redness. It is also very helpful for keeping oily skin balanced by cutting down on excess oil production, and it is well tolerated by most people.
Where does this serum go in a skincare routine for acne-prone skin?
This serum goes in the evening routine after cleansing and toning, and before moisturizing. Using it in the evening helps keep things simple and safe around sun exposure while calming blemishes and regulating oil production.
Can I use this serum with retinol, and in what order?
You can use this serum with retinol by applying it before your retinol product to help calm and hydrate your skin. Green tea extract and other soothing ingredients help lower the chance of irritation while supporting your skin barrier during active treatments.
How often should I use this serum?
This serum is a great fit for your acne-prone skin and can be used in your evening routine. Using it daily helps calm blemishes and regulate oil production without causing irritation.
Can this serum clog pores, cause breakouts or purging for acne-prone skin?
Isntree Green Tea Fresh Serum is a great fit for acne-prone skin because green tea extract helps calm blemishes and regulate oil production. The formula avoids harsh components and is unlikely to clog pores or cause breakouts.
Can I use this serum around the eyes or on my body?
This serum is safe to use around the eyes and on the body, though the skin around the eyes is much thinner than body skin and absorbs products very easily. Its soothing and calming ingredients make it gentle enough for delicate areas without causing irritation.
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.
