Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and antioxidant protection for your normal skin due to high concentrations of ascorbic acid and ascorbyl glucoside, which help even skin tone and shield from environmental stressors.
  • While sodium hyaluronate provides general hydration, the formula does not directly target your primary concern of wrinkles and fine lines.
  • The product is safe for your normal skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

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 Obagi Professional-C Serum 20% work for mature skin?

This serum works moderately well for mature skin by offering brightness and shield from daily stressors, but it does not directly target wrinkles and fine lines. A treatment for mature skin needs to be exceptionally safe, target wrinkles and fine lines with high-quality ingredients, perform its anti-aging function excellently, and be perfectly suitable for normal skin through potent antioxidants, hydrating components, and skin-repairing ingredients.

Journal of Cosmetic Dermatology, 2020International Journal of Molecular Sciences, 2024

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

Ascorbic acid and ascorbyl glucoside make this serum a good fit for mature skin by offering moderate brightening and antioxidant protection. Treatments that fit mature skin better need to safely target wrinkles and fine lines with high-quality, effective ingredients that improve skin elasticity and moisture retention.

Journal of Cosmetic Dermatology, 2020International Journal of Molecular Sciences, 2024

What does Vitamin C do for mature skin?

Vitamin C helps mature skin by smoothing out wrinkles, brightening dark spots, and boosting firmness. It works by encouraging collagen production to keep skin looking youthful and radiant.

Journal of Cosmetic Dermatology, 2020Journal of Cosmetic Dermatology, 2023

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 treatment serum goes in the evening routine after cleansing and before moisturizing. A mature skin product of this type also needs ingredients that directly target wrinkles and fine lines.

Can I use it with retinol, and in what order?

You can use this treatment with retinol by applying the retinol in your evening routine and using this vitamin C serum in the morning, which helps prevent potential irritation from combining strong actives at the same time. To improve your mature skin further, this type of product also needs ingredients that directly target wrinkles and fine lines.

How often should I use it?

You can use this treatment in the evening as part of your routine for mature skin. It offers moderate brightening and antioxidant protection, but a product of this type needs ingredients that directly smooth fine lines and target wrinkles for this skin.

Journal of Cosmetic Dermatology, 2020International Journal of Molecular Sciences, 2024

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

This serum is unlikely to clog pores or cause breakouts on mature skin, as it contains no harsh ingredients that typically trigger irritation or congestion. However, because it does not directly target wrinkles and fine lines, mature skin needs a product with ingredients that boost collagen and firm up the skin.

Is it fragrance-free and alcohol-free?

It has no fragrance and contains drying alcohol (alcohol).
