Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate anti-aging benefits for your dry skin, as adenosine and hydrolyzed soy protein help minimize fine lines, but the formula lacks specialized hydrating ingredients like ceramides or hyaluronic acid to effectively address dryness and flakiness.
  • The presence of alcohol denat may further exacerbate dryness, and while it offers general skincare benefits, the overall formulation is moderately unsuitable for your dry skin type.

How to apply

  • Apply this serum PM, starting 3×/week and working up to daily use as your skin adjusts.
  • Place the serum after cleansing and toner, but right before your moisturizer.
  • Gently press 2-3 drops of the serum into your skin and let it absorb for a minute.
  • Apply the serum on slightly damp skin to help lock in extra moisture.
  • Avoid the eye area and do a patch test before your first use.

Questions and answers

Why is Age Defender Power Serum a weak match for dry skin?

This serum is a weak match because it lacks specialized hydrating ingredients like ceramides or hyaluronic acid to address dry and flaky skin, and the alcohol denat inside may make dryness worse. A product of this type needs nourishing ingredients like ceramides, niacinamide, or peptides to provide deep hydration and support the skin barrier.

International Journal of Cosmetic Science, 2018Journal of Cosmetic Dermatology, 2019

Which ingredients make this serum a poor fit for dry skin?

Alcohol denat makes this serum a poor fit for dry skin because it may further dry out your skin, and the formula also lacks specialized hydrating ingredients like ceramides or hyaluronic acid to properly handle dryness and flakiness. Dry skin needs a treatment that includes ingredients that target hydration and skin barrier support, such as ceramides, niacinamide, propolis, bifida fermentation, or peptides.

What does Cypress Extract do for dry skin?

Cypress extract helps calm dry skin by reducing irritation and discomfort. This type of product needs soothing botanical ingredients and rich moisturizers to restore soft, smooth skin.

What does Glycerin do for dry skin?

Glycerin helps dry skin by drawing in moisture and keeping it locked in, which makes the skin feel much softer and smoother. It also supports your natural skin barrier to stop water from escaping easily. A product for dry skin needs extra ingredients like hyaluronic acid and soothing plant extracts to truly calm and hydrate dry patches.

Clinical, Cosmetic and Investigational Dermatology, 2017The British Journal of Dermatology, 2008

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

This treatment goes in the evening routine after cleansing and before moisturizing, though dry skin needs a product that includes strong hydrators like ceramides or hyaluronic acid to protect against flakiness.

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

You can use this treatment alongside retinol, but because your dry skin needs extra care, apply retinol first and follow with a rich moisturizer to prevent flakiness and irritation.

How often should I use this serum?

This serum is a weak match for dry skin, as alcohol denat may dry it out further while lacking deep hydrators like ceramides or hyaluronic acid. To care for dry skin, a product of this type needs rich moisturizing ingredients like ceramides and hyaluronic acid to lock in moisture and soothe flakiness.

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

This treatment is unlikely to clog pores or cause breakouts on dry skin, though alcohol denat may occasionally worsen dryness and flakiness. A product for this skin needs rich hydrating ingredients like ceramides or hyaluronic acid to lock in moisture and keep the skin soft and smooth.

Is it fragrance-free and alcohol-free?

It contains fragrance (parfum, limonene, linalool, and citral) and drying alcohol (alcohol denat).
