Silymarin + CF | Clarifying Antioxidant Serum

Liquid gold, not liquid grease. A highly specialized Vitamin C serum engineered specifically for oily and blemish-prone skin. We paired a potent 20% stable Vitamin C with Silymarin and Salicylic Acid to visibly brighten post-acne marks, control excess oil, and keep your pores clear—all in a beautifully lightweight, water-like finish.

Why You'll Love It:

• The Vitamin C for Acne-Prone Skin: Finally, a high-potency clinical Vitamin C that doesn't feel heavy, sticky, or cause new breakouts. We swapped the heavy lipids for clarifying acids.

• Stops Blackheads at the Source: Silymarin is a powerful antioxidant that specifically prevents sebum oxidation(the chemical reaction that turns oil into blackheads and triggers inflammation).

• Fades Post-Blemish Marks: Delivers an impressive 20% Vitamin C to rapidly blur the look of those frustrating red and brown spots left behind by old breakouts.

• Clears & Refines: Infused with 0.5% Salicylic Acid to gently sweep away dead skin cells inside the pore, instantly smoothing bumpy texture.

The Vitamin C Dilemma

If you have oily or blemish-prone skin, you've probably been burned by Vitamin C before. Most traditional clinical formulas rely heavily on Vitamin E and oily solvents, which can feel suffocating and trap debris in your pores. We knew you deserved the incredible collagen-boosting and brightening benefits of Vitamin C, minus the fear of waking up with a new spot.

The Cyrène Difference (A Smarter Formula)

To solve this, our Cosmetic Chemist completely re-engineered the classic antioxidant serum. First, we used a highly stable derivative of Vitamin C (Ethylated L-Ascorbic Acid) so it won't rapidly oxidize and turn brown in the bottle. Then, we introduced Silymarin (Milk Thistle Extract) to stop your natural oils from oxidizing on your face. Combined with pore-clearing Salicylic Acid, it's the ultimate daily defense for clear, bright, and resilient skin.

Inside The Formula

• 20% Ethylated L-Ascorbic Acid: A next-generation, highly stable form of Vitamin C. It penetrates deeply to boost healthy collagen and fade pigmentation without the rapid degradation (turning brown) or high irritation associated with older Vitamin C formulas.

• 0.5% Silymarin (Milk Thistle): A targeted plant-based antioxidant. It specifically prevents sebum from oxidizing, drastically reducing the environment where blemish-causing bacteria thrive.

• 0.5% Salicylic Acid (BHA): The gold standard for congested skin. It is oil-soluble, meaning it dives deep into your pores to dissolve excess sebum and refine texture.

• 0.8% Ferulic Acid: An antioxidant booster that stabilizes the formula and provides a fierce shield against daily environmental stressors like pollution and UV rays.

Your Morning Ritual

When to use: ONLY in the AM (Morning).

1. Cleanse: Wash away nighttime oil production with our AHA/BHA Exfoliating Gentle Cleansing Gel. Pat skin completely dry.

2. Treat: Apply 4-5 drops of Silymarin + CF to a dry face, neck, and chest. Gently press it into the skin. (Notice how quickly it absorbs—leaving a fresh, matte-like finish).

3. Moisturize: Follow with a lightweight, non-comedogenic moisturizer like our Skin Rescue Moisturiser.

4. Protect (Always): Finish with our Invisible Physical Sunscreen SPF 50. Sun protection is crucial to prevent those post-acne marks from getting darker.

The FAQs 

Q: Most clinical Vitamin C serums turn brown and go bad in a month. Will this? A: This is the biggest frustration with traditional pure L-Ascorbic Acid serums! We formulated Silymarin + CF using Ethylated L-Ascorbic Acid. This specific derivative is incredibly stable, meaning it stays potent (and clear/light) for significantly longer, so you get the full value out of every single drop.

Q: Does it have that typical "hot dog water" or metallic smell? A: Because we use a more advanced, stable form of Vitamin C and avoid certain degrading solvents, our formula has a much more neutral scent profile compared to the traditional, strong-smelling clinical serums on the market.

Q: Will this dry out my skin since it has Salicylic Acid? A: Not at all. We use a precise 0.5% concentration of Salicylic Acid—enough to keep the pores clear daily, but gentle enough that it respects your skin's natural moisture barrier. It leaves your skin feeling smooth and fresh, never stripped.

Q: I already use your 2% BHA Serum. Can I use both? A: Since Silymarin + CF provides your skin with a gentle daily dose of exfoliation, we recommend using this in your morning routine, and saving your Skin Renewing 2% BHA Serum for your evening routine. This ensures your pores stay clear without over-exfoliating.

What is Silymarin CF Clarifying Serum?

It is a lightweight morning antioxidant serum designed for oily and blemish-prone skin. The formula combines 20% ethylated vitamin C with silymarin, 0.5% salicylic acid, ferulic acid and hydrating support ingredients.

Is this a vitamin C serum for oily skin?

Yes. The formula was developed around oily and combination-skin concerns, including rich texture, visible congestion, post-blemish marks and difficulty layering vitamin C beneath sunscreen.

What type of vitamin C does it contain?

It contains 3-O-Ethyl Ascorbic Acid, an ethylated vitamin C derivative. It is not the same ingredient as pure L-ascorbic acid, so comparisons should consider the complete formula rather than percentage alone.

Is 20% ethylated vitamin C strong?

It is a high active level and may not suit every first-time or sensitive user. Introduce it gradually and reduce frequency if persistent dryness or stinging develops.

What does silymarin do in skincare?

Silymarin is associated with milk thistle and is used for antioxidant support. Product-specific claims about sebum oxidation must be based on Cyrene's own formula and evidence, not another brand's study.

Why does the formula contain salicylic acid?

Salicylic acid is oil-soluble and helps improve the visible appearance of congested texture and pores. This formula contains a stated 0.5%, subject to final documentation checks.

Can it help with post-blemish marks?

The formula is intended to improve the appearance of uneven tone and marks left after blemishes. Results vary, and daily sunscreen is important because UV exposure can make uneven pigmentation look more persistent.

Does it treat acne?

No. It is a cosmetic serum for blemish-prone skin and does not treat or cure acne. Seek medical advice for persistent, painful or scarring acne.

Will it clog pores or cause breakouts?

No cosmetic can guarantee that every person will remain breakout-free. The formula is designed with oily skin in mind, but individual response varies. Add a non-comedogenic claim only if appropriate evidence supports it.

Is the texture oily or sticky?

The intended finish is lightweight and water-like. Confirm the final sensory wording through testing. Apply a thin layer and let it settle before moisturiser and sunscreen.

Will the serum oxidise or turn brown?

Ethylated vitamin C is selected partly for formulation stability, but the finished product still needs approved storage and PAO guidance. Do not promise that oxidation is impossible. Replace the product if its colour, smell or texture changes outside the approved specification.

Does it smell like traditional vitamin C serum?

It is fragrance-free with a mild, pleasant natural scent from its ingredients.

Can salicylic acid dry the skin?

It can feel drying or irritating for some people, even at lower levels. This formula also contains glycerin, panthenol and sodium hyaluronate, but individual tolerance and the rest of the routine matter.

Can I use it every day?

It is intended for daily morning use once tolerated. Begin three times in the first week if you are new to high-strength vitamin C or salicylic acid.

Can I use vitamin C and salicylic acid together?

They are already combined in this formula. Avoid automatically stacking another leave-on BHA in the same routine, particularly if your skin is sensitive or new to acids.

Can I use it with niacinamide?

Yes, many routines can include both. Introduce products individually and use a simpler routine if your skin becomes uncomfortable.

Can I use it with retinal?

A simple approach is Silymarin CF in the morning and Diamond Retinal in the evening. Introduce each active gradually and use sunscreen every morning.

Can I use it with benzoyl peroxide or prescription acne treatment?

Ask the clinician or pharmacist managing your treatment. Combining several active products can increase dryness and irritation, and prescription directions take priority.

Do I need moisturiser after it?

Use a lightweight moisturiser if your skin needs it. Oily skin can still be dehydrated, and avoiding all moisturiser may leave an active routine less comfortable.

Do I need sunscreen?

Yes. Broad-spectrum sunscreen is the final morning step and is particularly important when post-blemish marks and uneven tone are concerns.

Is it suitable for sensitive skin?

This high-active formula contains vitamin C and salicylic acid, so sensitive skin should introduce it cautiously. Patch-test according to approved directions and do not apply to irritated or broken skin.
