Principia Mix-01 Multi-Acid Serum for Oil Control & Blemish-Prone Skin, 1.01 fl oz (30 mL)
Principia Mix-01 is a Brazilian dermocosmetics night serum created for modern, high-performance routines that prioritize clarity, comfort, and visible refinement. With a calibrated blend of 4 proven actives—5% niacinamide, 4% glycolic acid, 3% tranexamic acid, and 2% salicylic acid—this formula helps support a smoother-looking texture, less visible congestion, and a more balanced, luminous finish over time.
Key Ingredients
- Oil control: Helps reduce the look of excess shine and supports a more balanced finish.
- Blemish and blackhead care: Helps keep pores looking clearer and supports fewer visible clogs over time.
- Smoother texture: Helps refine the look of uneven texture for a softer feel.
- Radiance support: Helps improve the look of dullness for a healthier-looking glow.
- Pore appearance support: Helps reduce the look of enlarged pores with consistent nightly use.
-
Dermatologically tested (brand-reported): The brand reports primary irritation and sensitization testing with no irritation observed in participants.
How to use
- Apply on alternate nights for 1 week, then every night as tolerated.
- Use on clean, dry skin before creams.
- Dispense a few drops onto fingertips (avoid touching the dropper to skin) and spread gently over the face.
- Avoid the eye area. Use sunscreen daily and minimize sun exposure while using exfoliating acids.
Ingredients Highlights
- Niacinamide (5%): A stable form of vitamin B3 associated with supporting oil balance and improving the look of blemish-prone skin. Commonly used to help refine the look of pores and uneven texture in modern routines.
- Glycolic Acid (4%): A sugarcane-derived AHA with a small molecular size that helps promote surface-level exfoliation and skin renewal, supporting a smoother look and helping prevent the buildup of dead skin cells that can make pores look more noticeable.
- Tranexamic Acid (3%): A synthetic derivative of the amino acid lysine used in skincare to help support a more even-looking tone and reduce the appearance of dark marks, including those related to blemishes and sun exposure (appearance-focused cosmetic claim).
-
Salicylic Acid (2%): A BHA known for supporting pore clarity by helping exfoliate inside the pore lining. Commonly used in routines that target excess oil and the look of blackheads and blemishes.

FAQ
Is Principia Mix-01 suitable for all skin types?
The brand indicates it is suitable for all skin types. Because it contains multiple exfoliating acids, sensitive skin types may prefer a slower introduction.
How often should I use Mix-01?
Start on alternate nights for one week, then use nightly as tolerated. If dryness occurs, reduce frequency and support with a barrier-friendly moisturizer.
Can I use Mix-01 with vitamin C or retinoids?
Many routines can combine actives, but to reduce the risk of irritation, consider alternating nights and avoid stacking multiple strong exfoliants in the same routine.
Can I apply Mix-01 near my eyes?
No. Avoid the eye area and eyelids, and do not apply on the corners of the nose and mouth if those areas are easily irritated.
Is this product cruelty-free?
The brand states it does not test on animals.
