Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Suitable for normal skin due to niacinamide and panthenol, which support barrier repair and hydration, but azelaic acid offers moderate treatment for acne-prone skin, not your primary concern of wrinkles and fine lines.
  • Aloe barbadensis leaf extract and panthenol provide general skincare benefits like soothing and hydration, which are supportive but not directly targeted at addressing wrinkles and fine lines.
  • The product is generally safe for your normal skin, with a low risk of irritation from azelaic acid.

How to apply

  • Use this serum in your PM routine. Start by applying it 3 times a week, and work up to daily use if your skin likes it.
  • Apply this serum after your toner and before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
  • You can apply the serum on dry skin for the best results against fine lines.
  • Always do a patch test before your first use and avoid the sensitive eye area.

Questions and answers

How well does Cos De BAHA Azelaic Acid 10% Serum work for mature skin?

This serum works for mature skin, though other products fit it better because its ingredients focus more on soothing and hydration than on directly smoothing wrinkles and fine lines. To truly care for mature skin, a product of this type needs high-quality anti-aging ingredients and potent antioxidants to improve skin elasticity and target fine lines.

Which ingredients make this serum a good fit for mature skin?

Niacinamide and panthenol make this serum a good fit for mature skin by supporting barrier repair and hydration. However, because wrinkles and fine lines are your main concern, this product needs potent antioxidants, hydrating components, and skin-repairing ingredients that directly target aging.

The Journal of Dermatological Treatment, 2017American Journal of Clinical Dermatology, 2002

What does Azelaic Acid do for mature skin?

Azelaic acid helps mature skin by targeting dark spots and uneven tone, while supporting smoother texture and a more youthful look. It provides antioxidant benefits that may reduce signs of aging and protect skin from environmental stress.

Frontiers in Medicine, 2026Journal of Cosmetic Dermatology, 2022

What does Hyaluronic Acid do for mature skin?

Hyaluronic acid helps mature skin by deeply boosting moisture, improving elasticity, and smoothing the appearance of fine lines and wrinkles. Regular use keeps the skin looking plump and soft while supporting overall firmness and hydration.

Journal of Drugs in Dermatology, 2011Skin Research and Technology, 2024

Where does this serum go in a skincare routine for mature skin?

This serum goes in the evening routine after cleansing and before moisturizing, as treatments with active ingredients are typically used at night for simplicity and extra safety around sun exposure. Because your primary concern is wrinkles and fine lines, mature skin needs targeted ingredients like peptides or retinoids that directly address signs of aging rather than general soothing and hydration.

Can I use this serum with retinol, and in what order?

You can use this serum with retinol by applying the serum first and following with your retinol product, or by using them on alternating nights to keep your skin calm. This product is generally safe for normal skin with a low risk of irritation, but mature skin needs targeted ingredients like peptides and retinoids to effectively smooth fine lines and wrinkles.

How often should I use this serum?

Apply this serum in your evening routine, starting once a week to see how your skin responds before gradually increasing frequency if well tolerated. Mature skin seeking smoother, firmer texture needs dedicated anti-aging ingredients like retinoids, peptides, or antioxidants that directly target fine lines and wrinkles.

Can this serum clog pores, cause breakouts or purging for mature skin?

This serum is unlikely to cause breakouts for mature skin, and reviewer complaints of breakouts are low. However, mature skin looking to smooth wrinkles needs products with ingredients that directly target fine lines and firmness, such as retinoids or peptides.

Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
