Page built Nov 8, 2026How the Fit score works

Lovi Assistant explains

  • Offers moderate brightening and smoothing for your dry skin due to ascorbic acid, which can be drying and lacks sufficient humectant or emollient ingredients to counteract this effect.
  • While allantoin and tocopherol provide some soothing benefits, they do not directly address the core issue of dryness or flakiness.
  • The formulation is safe for your dry skin, as it contains no harsh ingredients and includes soothing components like allantoin and tocopherol.

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 does Lovi advise caution with Dr. Althea Vitamin C 50% Boosting Powder for dry skin?

Lovi advises caution because this treatment can be drying on dry skin and lacks enough moisturizing or softening ingredients to counteract that effect. A product of this type needs rich moisturizing ingredients, soothing components, and skin-repairing elements that target dryness, flakiness, and barrier support.

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

This treatment is a poor fit for dry skin because its high amount of ascorbic acid can be drying and lacks enough softening or moisturizing ingredients to balance it out. A treatment for dry skin needs ingredients that focus heavily on deep hydration, skin barrier support, and soothing nourishment like propolis, niacinamide, ceramides, and peptides.

What does Vitamin C do for dry skin?

Vitamin C helps dry skin by boosting moisture and keeping the surface smooth and soft. It may also improve skin hydration and support the outer protective barrier over time.

Skin Research and Technology, 2008Experimental Dermatology, 2008

What does Silica do for dry skin?

Silica helps absorb excess oil while maintaining moisture, making it a useful addition for balancing skin. It works to keep your face feeling smooth and soft without causing extra dryness.

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

This treatment goes in the evening routine for dry skin, placed after cleansing and before moisturizing. Because this product can be drying and lacks enough moisturizing or softening ingredients to balance that effect, dry skin needs a product packed with rich hydrators and soothing skin softeners to keep it comfortable.

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

You should use caution when combining this treatment with retinol on dry skin, as it may cause additional dryness and irritation. If you choose to use both, apply the retinol first, let it absorb completely, and follow with this powder mixed into a rich moisturizer to help protect your skin. Dry skin needs formulas packed with heavy moisturizers and hydrating ingredients like glycerin or hyaluronic acid to prevent flakiness and keep it soft and smooth.

How often should I use this treatment?

This treatment should be used once a week to start, because it can be drying on dry skin. To work well for dry skin, a product of this type needs enough hydrating and softening ingredients to keep the skin comfortable and smooth.

Journal of Cosmetic Dermatology, 2020

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

This treatment is unlikely to clog pores or cause breakouts on dry skin, as it contains no heavy or harsh ingredients that typically block pores. However, because it lacks enough moisturizing and softening ingredients, a product of this type needs added richer oils or hydrating components to properly care for dry skin.

Is this treatment fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
