Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate wrinkle reduction for you due to retinol promoting smoothing texture and minimizing fine lines, while squalane and tocopherol provide hydration and antioxidant support for your dry and flaky skin.
- The formula contains squalane and tocopherol to nourish your dry skin, but the retinol may pose risks of worsening dryness and sensitivity.
How to apply
- Use this PM routine for your evening skincare. Start using the serum 3 times a week and increase to daily use if your skin feels comfortable.
- Apply the serum after cleansing and toner, but right before your moisturizer. This step locks in deep hydration for dry skin.
- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.
- Since your skin is sensitive, apply the serum on completely dry skin for better tolerance and less irritation.
- Avoid the sensitive eye area during application. Always do a patch test before your first use to ensure your skin reacts well.
People Say
★4.5Overall rating based on 1.0k+ reviewsBased on a very large amount of data, users with dry, mature, or sensitive skin highly praise this oil for its gentle yet effective formula, noting significant improvements in skin texture, radiance, and fine lines without irritation. The rich oil base can be too heavy for oily or acne-prone skin types, leading to congestion, and many users find the short three-month shelf life after opening to be a major inconvenience.

Retinol is often too strong for dry sensitive skin because it may cause scaling and stinging, so a product of this type needs gentle soothing ingredients and extra moisture to keep the skin calm and smooth.
The British Journal of Dermatology, 2019Toxicology Letters, 2003
What does Squalane do for dry sensitive skin?
Squalane helps keep dry sensitive skin soft and smooth by locking in moisture and calming irritation without causing flare-ups. It is unlikely to cause redness or discomfort, making it a gentle choice that supports the skin barrier. This type of skin needs ingredients that deeply hydrate and soothe, such as plant oils and antioxidants.
International Journal of Molecular Sciences, 2017Molecules, 2009
Where does this treatment go in a skincare routine for dry sensitive skin?
This treatment goes in the evening routine after your toner and before your moisturizer, but because your skin is dry and sensitive, this product is a weak match that may worsen your dryness and sensitivity.

Can I use this treatment with vitamin C, and in what order?
It is best to avoid using this strong retinol treatment and vitamin C at the same time, as using them together may easily irritate dry and sensitive skin. Instead, a product of this type for this skin needs soothing ingredients and extra hydration to keep skin calm and comfortable.
How often should I use this treatment?
This treatment is a weak match for dry sensitive skin because the retinol may worsen dryness and irritation. A product of this type needs extra soothing, hydrating ingredients like squalane and vitamin E to calm the skin and keep it comfortable.
Clinical, Cosmetic and Investigational Dermatology, 2023Facial Plastic Surgery, 2014
Can this treatment clog pores, cause breakouts or purging for dry sensitive skin?

Is this treatment fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol.
