According to the brand, there are virtually no restrictions on combining Mix-01 with other actives. However, avoid layering with additional strong acids or retinol on the same night.
Ingredient breakdown
INGREDIENTSNiacinamide (Vitamin B3) 5%Proven
A multitasking form of vitamin B3 that strengthens the skin barrier, regulates sebum production, reduces pore appearance, fades dark spots, and improves overall skin texture. One of the most well-researched and versatile skincare actives.
- Sebum Control: Studies show 5% niacinamide significantly reduces sebum excretion rate after 4 weeks of use.
- Barrier Support: Boosts ceramide synthesis and strengthens the lipid barrier, reducing transepidermal water loss.
- Pigmentation: Inhibits melanosome transfer from melanocytes to keratinocytes, helping to fade dark spots over time.
Glycolic Acid (AHA) 4%Proven
The smallest and most penetrating alpha hydroxy acid, derived from sugar cane. Dissolves the bonds between dead skin cells to accelerate cell turnover, revealing smoother, brighter skin underneath. Stimulates collagen production over time.
- Exfoliation: Its small molecular size (76 Da) allows deeper penetration than other AHAs for effective chemical exfoliation.
- Cell Renewal: Promotes natural regeneration by accelerating the shedding of dead skin cells.
- Pore Refinement: Clears dead cell buildup from pore walls, helping minimize their visible appearance.
Tranexamic Acid 3%Promising
A synthetic amino acid derivative originally used in medicine to reduce bleeding. In skincare, it inhibits melanin production by blocking the plasminogen/plasmin pathway, making it a powerful brightening agent for stubborn hyperpigmentation and post-inflammatory marks.
- Hyperpigmentation: Clinical trials show significant improvement in melasma and post-inflammatory hyperpigmentation with topical use at 2-5%.
- Gentle Brightening: Works differently than hydroquinone with a much lower risk of irritation or rebound pigmentation.
- Synergy: Works synergistically with niacinamide for enhanced brightening and anti-inflammatory effects.
Salicylic Acid (BHA) 2%Proven
The gold standard beta hydroxy acid for acne-prone skin. Unlike AHAs, salicylic acid is oil-soluble, allowing it to penetrate deep into pores to dissolve sebum plugs, reduce inflammation, and prevent new breakouts from forming.
- Pore Penetration: Oil-soluble nature allows it to work inside clogged pores where AHAs cannot reach.
- Anti-Inflammatory: Structurally related to aspirin, providing soothing and anti-inflammatory benefits to irritated, acne-prone skin.
- FDA Recognized: 2% is the maximum OTC concentration recognized by the U.S. FDA for topical acne treatment.
Sodium Hyaluronate <1%Proven
The sodium salt form of hyaluronic acid with a smaller molecular weight, allowing deeper skin penetration. Attracts and holds up to 1,000 times its weight in water, providing hydration to counterbalance the drying effects of the acids in this formula.
- Hydration: Acts as a powerful humectant, drawing moisture from the environment into the skin layers.
- Barrier Support: Helps maintain skin hydration and plumpness even while using exfoliating acids.

How to use
HOW TO USECleanse Your Face
Start with clean, dry skin. Remove all makeup and impurities with a gentle cleanser and pat dry completely.
Dispense a Few Drops
Without touching the cannula to the skin, dispense 3-4 drops onto your fingertips or directly onto your face.
Spread Gently
Gently spread the serum evenly over your entire face, avoiding the eye area, eyelids, and outer corners of the nose and mouth.
Follow with Moisturizer
Allow the serum to absorb for 1-2 minutes, then apply a hydrating moisturizer suited to your skin type to lock in benefits.
Apply Sunscreen in the Morning
The next morning, always apply a broad-spectrum sunscreen SPF 30+ to protect skin from UV sensitivity caused by acids.
Who is it for?
WHOPerfect for you if:
- You struggle with acne, blackheads, and clogged pores
- You have oily or combination skin with excess shine
- You want to fade dark spots and post-acne marks
- You prefer a minimalist, multi-active approach
- You are looking for an affordable yet effective acid serum
- You want a fragrance-free, clean formula
Consider alternatives if:
- You are pregnant or breastfeeding (contains salicylic acid)
- You have very dry or dehydrated skin without oiliness
- You are extremely sensitive and cannot tolerate any acids
- You are already using multiple strong acid products
- You need a morning serum (this is PM-only due to photosensitivity)
Skin type compatibility
SKIN TYPESIdeal match. BHA and niacinamide work together to control sebum, while the oil-free formula absorbs instantly without adding shine.
Lightweight fluid balances well across oily and dry zones. AHA/BHA combo addresses T-zone congestion without over-drying cheeks.
Non-comedogenic, fungal-acne safe, oil-free formula with both AHA and BHA to clear existing breakouts and prevent new ones.
Good for refining texture and brightening, though the full acid combo may be more than normal skin needs. Can use 2-3 times per week.
Fragrance-free is a plus, but the 4-acid combination may cause stinging or redness. Start very slowly and apply hyaluronic acid underneath to buffer.
AHA and BHA can exacerbate dryness. If you do use it, limit to 1-2 nights per week and always follow with a rich moisturizer.
Results timeline

DUPES
Shares the niacinamide for oil control and pore refinement, but lacks glycolic acid, tranexamic acid, and salicylic acid. You would need to layer separate acid products to replicate the full Mix-01 effect.
Contains both AHA (glycolic) and BHA (salicylic) for exfoliation and pore clearing. However, concentrations are lower, lacks niacinamide and tranexamic acid, and comes in a toner format rather than a treatment serum.
Combines niacinamide with tranexamic acid for brightening, but lacks the AHA/BHA exfoliating component. Better for pigmentation-only concerns without the acne-fighting power.
Focused on 2% salicylic acid (BHA) for pore clearing and acne treatment. Simpler formula that addresses only the BHA component of Mix-01 without AHA, niacinamide, or tranexamic acid.

Frequently asked questions
FAQNo. Principia Mix-01 contains 2% salicylic acid (BHA), which is generally recommended to avoid during pregnancy and breastfeeding. It also contains 4% glycolic acid (AHA), which may cause increased skin sensitivity. Most dermatologists advise against using BHA products while pregnant or nursing. Please consult your OB/GYN or dermatologist for personalized guidance.
Yes. Principia Mix-01 is fungal acne safe. Its formula contains no oils, fatty acids, fatty acid esters, ferments, or polysorbates — the common triggers that feed Malassezia yeast. The oil-free, silicone-free formula with only 15 ingredients makes it one of the cleanest options for fungal acne sufferers who also want acid exfoliation.
According to the brand, there are virtually no restrictions on using Mix-01 with other actives. However, since Mix-01 already contains both AHA (glycolic) and BHA (salicylic), layering additional acid exfoliants on the same night may cause excessive irritation. If you use retinol, alternate nights: Mix-01 one evening, retinol the next. Vitamin C is best used in the morning while Mix-01 is used at night.
Principia Mix-01 is best suited for oily, combination, and acne-prone skin types. Its oil-free, lightweight formula controls sebum, clears pores with salicylic acid, and smooths texture with glycolic acid. Those with normal skin can also benefit by using it 2-3 times per week. It may be too active for very dry or extremely sensitive skin without careful introduction.
Most users report smoother texture and reduced oiliness within 2-4 weeks. Visible improvement in blackheads and acne typically appears by week 4. Dark spot fading and improved radiance take 4-8 weeks. Full results including pore refinement and even tone are generally seen at the 8-12 week mark with consistent nightly use.
Apply Mix-01 as step 3 in your evening routine: (1) Cleanser, (2) Toner (optional), (3) Mix-01 Serum on clean, dry skin, (4) Moisturizer. In the morning, apply sunscreen. During the first week, use on alternate nights only. The brand recommends using it before creams, sunscreen, and makeup.
No. Principia Mix-01 has a comedogenic rating of 0/5. It is completely oil-free, silicone-free, and contains no known pore-clogging ingredients. In fact, the salicylic acid (BHA) in the formula actively works to unclog pores, while glycolic acid (AHA) clears dead cell buildup from pore walls. It is recommended for acne-prone skin.
Principia Mix-01 should be used within 6 months after opening (6M PAO). The amber glass bottle helps protect the active acids from light degradation. Store in a cool, dry place with the cap tightly sealed. If the product changes color, consistency, or develops an unusual odor, discontinue use.
Verdict: Principia Mix-01 delivers exceptional multi-active performance at an unbeatable price point. Combining four clinically-backed ingredients — niacinamide, glycolic acid, tranexamic acid, and salicylic acid — in a clean 15-ingredient formula, it effectively addresses acne, blackheads, dark spots, and oiliness simultaneously. The minimalist, oil-free formulation is ideal for oily and acne-prone skin types seeking a streamlined routine. While the strong alcohol scent and initial adjustment period may deter some users, the results speak for themselves: smoother texture, fewer breakouts, and visibly brighter skin within weeks. Often compared to The Ordinary for its transparent, no-frills approach, this Brazilian gem is a standout choice for anyone looking for maximum active performance without the premium price tag.

Silicone-Free
Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.

Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
What are Notable Effects & Ingredients?
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Pro Tip Alert!
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

What is the Ingredient Safety Breakdown?
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
Pro Tip Alert!
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
