Page built Nov 8, 2026How the Fit score works
Lovi Assistant explains
- Offers moderate exfoliation for your dry skin due to lactic acid, which helps smooth texture, while squalane and glycerin provide some hydration. However, the formula lacks sufficient emollient and occlusive ingredients to fully address dryness.
- The presence of lavender oil may pose a slight irritation risk for sensitive skin, though it is generally well-tolerated.
- The product is generally safe for your dry skin with a low risk of irritation.
How to apply
- Use this exfoliant as part of your PM routine once a week, increasing slowly to twice a week if your dry skin tolerates it well. Always remember to apply SPF every morning to protect your newly smoothed skin.
- Apply the exfoliant after cleansing and toning, but always before your rich moisturizer.
- Gently press 2-3 drops of the exfoliant into your skin and let it absorb for a minute. Avoid rubbing to prevent any irritation on flaky areas.
- Apply the product directly to dry clean skin to ensure the best possible tolerance for your dry type. This helps address flaky patches without causing extra stress.
- Avoid the sensitive eye area and do a quick patch test before your very first use. Do not mix this with other strong acids or retinoids on the same night.

Questions and answers
How well does Biossance Squalane + Lactic Acid Resurfacing Night Serum work for dry skin?
This serum works moderately well for dry skin, providing some smoothness through lactic acid and basic hydration from squalane and glycerin. However, because it lacks sufficient heavy moisturizers and sealing ingredients to fully lock in moisture, a dry skin routine of this type needs rich soothing ingredients, ceramides, or peptides to deeply nourish and support the skin barrier.
Which ingredients make this serum a good fit for dry skin?
Lactic acid smooths texture while squalane and glycerin provide some hydration. However, an exfoliant treatment for dry skin needs rich hydrating and barrier-supporting ingredients like ceramides, niacinamide, or peptides to fully address dryness without irritation.
What does Squalane do for dry skin?
Squalane helps keep dry skin soft and smooth by acting as a hydrating agent that locks in moisture and prevents water loss. It is unlikely to cause irritation and may protect the skin from damage while improving overall hydration.
Advances in Food and Nutrition Research, 2012Molecules, 2009
What does Lactic Acid do for dry skin?
Lactic acid helps relieve dry skin by drawing in moisture and strengthening the skin's barrier so it stays soft and smooth. This ingredient gently sheds dead cells and supports natural moisturizing factors, making it very useful for improving rough or flaky areas.
International Journal of Dermatology, 2025Skin Research and Technology, 2013
Where does this serum go in a skincare routine for dry skin?
This treatment goes in the evening routine after cleansing, because Lovi routines put treatments there for simplicity and extra safety around sun exposure. Dry skin needs a product of this type to include rich moisturizing ingredients and oils to fully lock in hydration and prevent dryness.
Can I use this serum with retinol, and in what order?
It is best to use this exfoliating serum on a different night than retinol to avoid irritation, as combining strong treatments can be too harsh for dry skin.
How often should I use this serum?
Start by using this serum once a week in the evening, and if your skin feels comfortable and you see good results, you can carefully use it more often. This dry skin needs a product that includes rich, deeply nourishing ingredients that trap moisture and keep your skin soft and smooth.
Can this serum clog pores, cause breakouts or purging for dry skin?
This serum is unlikely to cause breakouts for dry skin, though it carries a low risk of irritation. Because this is an average fit for your skin, a product of this type needs richer rich oils and heavy moisturizing ingredients to lock in hydration and fully care for dry skin.
Is this serum fragrance-free and alcohol-free?
It has no drying alcohol and contains fragrance (linalool). Cetearyl alcohol is a fatty alcohol, which soften the skin.
