Collection: Face Serums

Physician-formulated face serums for anti-aging, brightening, peptides, and antioxidant defense. A serum is the most concentrated step in a skincare routine — and where most of the visible work happens. The Dr. Rusnak Wellness serum collection delivers targeted actives in clinically meaningful concentrations, formulated to support smoother, more even-looking, and more resilient skin.

Every serum in this line is developed by Dr. Cecilia Rusnak, a licensed acupuncture physician and paramedical aesthetician with more than a decade of clinical experience. Formulations are vegan, cruelty-free, paraben-free, and balanced to minimize the irritation that often accompanies highly concentrated active ingredients.

How to choose the right serum

  • For fine lines and firmness: Peptide Renewal Complex or Qi Firm Peptide Renewal
  • For dullness, dark spots, and uneven tone: Qi C+ Corrective Serum or Qi Brightening Corrective Serum
  • For redness, blemishes, and post-inflammatory marks: Azelaic Skin Corrector 10%
  • For deep hydration and smoother texture: peptide and antioxidant-based serums layered under moisturizer

How to layer serums correctly

  1. Cleanse
  2. Apply toner (optional)
  3. Apply water-based serums first (vitamin C, peptides)
  4. Apply heavier or oil-based serums second
  5. Wait 60-90 seconds between layers for absorption
  6. Seal with moisturizer
  7. Finish with SPF every morning

Frequently asked questions

How many serums can I use at once?
Most routines work well with one or two serums. More than three can be redundant, dilute results, and increase irritation risk. Pick the one or two actives that match your top concerns.

Can I use vitamin C and peptide serums together?
Yes — they pair very well. Vitamin C in the morning for antioxidant protection, peptides in the evening for repair and renewal is a common and well-tolerated approach.

How much serum should I use?
A few drops (typically two to four) are enough for the entire face and neck. More product does not equal more results — it can actually impair absorption.

Do serums replace moisturizer?
No. Serums deliver active ingredients; moisturizers provide hydration and seal in those actives. Always apply a moisturizer after your serum.

How long should a bottle of serum last?
A 30ml serum used twice daily typically lasts six to eight weeks. Once opened, most serums are best used within six months for maximum potency.
