🧪 Key Ingredients
🍊 L-Ascorbic Acid 15% Proven
The gold standard form of vitamin C, proven to neutralize free radicals, stimulate collagen synthesis, and brighten skin. At 15%, this is the optimal concentration for efficacy without excessive irritation.
- Research: L-ascorbic acid at 15% provides optimal antioxidant protection per Duke University studies
- Benefit: Protects against UV and pollution damage, stimulates collagen production
- pH Level: Formulated at low pH (2.5-3.5) for maximum absorption
🌿 Silymarin (Milk Thistle) 0.5% Proven
A powerful plant-based antioxidant derived from milk thistle that specifically targets oil oxidation—a key trigger for blemish formation. This is the unique differentiator of this formula.
- Research: Studies show silymarin has potent antioxidant and anti-inflammatory properties
- Benefit: Prevents sebum oxidation which leads to breakouts and premature aging
- Unique: Replaces vitamin E found in CE Ferulic, making it suitable for oily/acne-prone skin
🌾 Ferulic Acid 0.5% Proven
A plant-based antioxidant that stabilizes and enhances the efficacy of vitamin C. Provides synergistic protection against environmental damage.
- Research: Doubles vitamin C's photoprotective effects when combined (Duke study)
- Benefit: Stabilizes the formula and boosts overall antioxidant activity
💊 Salicylic Acid 0.5% Proven
A beta-hydroxy acid (BHA) that penetrates into pores to dissolve excess sebum and dead skin cells. Provides gentle exfoliation and anti-inflammatory benefits.
- Research: BHA is oil-soluble, allowing it to penetrate and unclog pores
- Benefit: Refines texture, minimizes pores, and prevents blackheads

No, Silymarin CF is not recommended during pregnancy due to its 0.5% salicylic acid content. While the concentration is low for topical use, medical professionals generally advise avoiding BHAs during pregnancy. For breastfeeding, consult your healthcare provider—while topical absorption is minimal, it's best to discuss with your doctor. SkinCeuticals CE Ferulic (without salicylic acid) may be a safer alternative during this time.
Yes, Silymarin CF is fungal acne safe. The formula is free from oils, fermented ingredients, fatty acids, esters, and polysorbates that can feed malassezia yeast. The oil-free, lightweight formula makes it an excellent choice for those dealing with fungal acne while still wanting the benefits of a potent vitamin C serum.
Silymarin CF already contains vitamin C and BHA (salicylic acid), so you don't need additional vitamin C products. For retinol: use Silymarin CF in the morning and retinol at night to avoid irritation. For additional AHA/BHA: proceed with caution as Silymarin CF contains 0.5% salicylic acid—adding more acids may cause over-exfoliation. If using additional exfoliants, alternate days. Silymarin CF pairs well with niacinamide.
Silymarin CF is specifically designed for oily and blemish-prone skin. It's excellent for combination skin (especially oily T-zones) and acne-prone skin types. The oil-free formula with silymarin (instead of vitamin E found in CE Ferulic) prevents the oiliness and breakouts some users experience with other vitamin C serums. It's not ideal for dry or dehydrated skin due to the high alcohol content—those skin types should consider CE Ferulic instead.
Results timeline varies but most users report: Week 1 - Reduced oiliness and shine (16% reduction clinically proven). Weeks 2-4 - Improved skin clarity, radiance, and refined pores (76% reduction in oil oxidation). Weeks 4-6 - Fewer breakouts and clearer complexion. Week 8+ - Visible improvement in fine lines (24% improvement clinically proven) and overall skin tone. For best results, use consistently every morning.
Apply Silymarin CF in the morning only, after cleansing and toning, on completely dry skin. Use 4-5 drops, press gently into face, neck, and chest. Wait 1-2 minutes for absorption, then follow with your other serums, moisturizer, and always finish with SPF 30+. Do not use at night—vitamin C serums are most effective during the day when they can protect against environmental damage.
No, Silymarin CF has a comedogenic rating of 0 and is specifically formulated not to clog pores. The oil-free formula contains no ingredients known to cause comedones. In fact, the 0.5% salicylic acid actively helps unclog pores. Some users experience initial "purging" (temporary breakouts) as the BHA brings existing congestion to the surface, but this typically resolves within 2-4 weeks.
Once opened, use Silymarin CF within 3-4 months for optimal efficacy. L-ascorbic acid oxidizes when exposed to air, light, and heat. Signs of oxidation include color change (turning yellow, orange, or brown) and loss of effectiveness. Store in a cool, dark place away from direct sunlight. The dropper bottle design helps minimize air exposure. With daily use of 4-5 drops, one 30ml bottle typically lasts 3-4 months.

Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
