The Ordinary Resveratrol 3% + Ferulic Acid 3% is a cosmetic skincare serum containing plant-derived antioxidants marketed for anti-ageing benefits. Resveratrol, found in grapes and berries, and ferulic acid, present in oats and rice, are formulated together in an oil-free base for topical facial application. Whilst both compounds have been studied for their antioxidant properties in laboratory settings, cosmetic products are not regulated as medicines by the MHRA and do not require the same clinical trial evidence as pharmaceutical preparations. Individual responses vary considerably, and those with specific dermatological concerns should consult a GP or dermatologist for evidence-based treatment options.

What Is The Ordinary Resveratrol and Ferulic Acid?

The Ordinary Resveratrol 3% + Ferulic Acid 3% is a cosmetic skincare serum containing two plant-derived antioxidant compounds. Resveratrol is a polyphenolic compound naturally found in grapes, berries, and certain plants, whilst ferulic acid is a hydroxycinnamic acid present in the cell walls of plants such as oats, rice, and apples. This product is formulated as an anhydrous, oil-free serum with a propanediol base, designed for topical application to facial skin.

Both resveratrol and ferulic acid have been studied for their antioxidant properties in laboratory and clinical settings. Antioxidants are substances that may help neutralise free radicals—unstable molecules generated by environmental stressors such as ultraviolet (UV) radiation, pollution, and normal metabolic processes. Free radical damage is implicated in premature skin ageing, including fine lines, wrinkles, and uneven pigmentation.

It is important to note that whilst The Ordinary markets this product as a skincare treatment, cosmetic products are not regulated as medicines by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Instead, they fall under the UK Cosmetics Regulation (retained EU 1223/2009) overseen by the Office for Product Safety and Standards (OPSS). Unlike pharmaceutical preparations, cosmetic skincare products do not require the same rigorous clinical trial evidence to support efficacy claims. The product is intended for external use only and should not be ingested or applied to broken skin.

Consumers should be aware that individual responses to cosmetic skincare vary considerably. What works well for one person may not produce the same results for another, and there is limited and inconclusive clinical evidence for anti-ageing benefits of topical resveratrol and ferulic acid in humans. Those with specific dermatological concerns should consult a GP or dermatologist for evidence-based treatment options.

How Does Resveratrol and Ferulic Acid Work on Skin?

The proposed mechanism of action for topical resveratrol and ferulic acid centres on their antioxidant and photoprotective properties. When applied to the skin, these compounds may help mitigate oxidative stress by donating electrons to free radicals, thereby stabilising them and potentially reducing cellular damage. This theoretical mechanism has been explored in various in vitro (laboratory) and some human studies, though the clinical significance of topical application remains an area of ongoing research.

Resveratrol has been investigated for its potential to activate certain cellular pathways, including sirtuins—proteins involved in cellular repair and longevity. Some laboratory and animal studies suggest resveratrol may influence collagen synthesis and inhibit enzymes that break down the extracellular matrix, though translating these findings to meaningful clinical outcomes in human skin requires further robust evidence. Additionally, resveratrol may possess anti-inflammatory properties that could theoretically benefit inflammatory skin conditions, though there is insufficient clinical evidence for therapeutic use.

Ferulic acid is thought to enhance the stability and efficacy of other antioxidants, particularly vitamins C and E, when formulated together in specific products. This stabilising effect does not apply to this particular product, which does not contain vitamins C or E. Some research suggests that ferulic acid can absorb some UV radiation, but it is important to emphasise that this product has not been tested as a sunscreen and provides no measurable SPF protection.

It is crucial to emphasise that topical antioxidants should not replace sun protection. NHS guidance recommends using sunscreen with SPF 30 or higher and high UVA protection (4 or 5 stars) when the UV index is 3 or higher (typically March to October in the UK). Sunscreen should be applied generously and reapplied regularly, alongside seeking shade and covering up. Antioxidant serums may complement, but cannot substitute for, proper photoprotection measures.

How to Use The Ordinary Resveratrol and Ferulic Acid Safely

Before incorporating any new skincare product into your routine, it is advisable to perform a patch test to assess for potential sensitivity or allergic reactions. Apply a small amount of the serum to a discreet area of skin, such as the inner forearm or behind the ear, and observe for 24–48 hours. If redness, itching, swelling, or irritation develops, discontinue use and do not apply to the face.

When using The Ordinary Resveratrol and Ferulic Acid serum, follow these general guidelines:

• Cleanse your face thoroughly before application to remove makeup, dirt, and excess oils

• Apply the serum to dry skin, preferably in the evening, as resveratrol may be sensitive to light and heat

• Use a few drops and gently massage into the face and neck, avoiding the immediate eye area

• Allow the serum to absorb fully (approximately 5–10 minutes) before applying additional products

• Follow with a moisturiser if desired, as this anhydrous serum may not provide sufficient hydration alone

• Always apply broad-spectrum sunscreen (SPF 30 or higher with high UVA protection) the following morning, as antioxidants do not provide UV protection

The product should be stored in a cool, dark place away from direct sunlight and heat sources, as both resveratrol and ferulic acid can degrade when exposed to light and elevated temperatures. Check the product's expiry date and discard if the colour, consistency, or smell changes significantly.

Do not use this product on broken, irritated, or inflamed skin. If you are using prescription topical medications such as retinoids, benzoyl peroxide, or corticosteroids, consult your GP or dermatologist before adding new products to ensure compatibility and avoid potential interactions or irritation.

Potential Side Effects and Skin Reactions

Whilst many individuals tolerate The Ordinary Resveratrol and Ferulic Acid serum without difficulty, adverse reactions can occur, particularly in those with sensitive skin or specific allergies. Common side effects associated with topical antioxidant serums may include:

• Mild irritation: Temporary redness, tingling, or warmth upon application

• Contact dermatitis: Allergic or irritant reactions manifesting as itching, rash, or inflammation

• Dryness or flaking: Particularly if used in combination with other active ingredients

• Breakouts: Some individuals with acne-prone skin may experience increased comedones (blackheads/whiteheads) or acne

Some users with acne-prone skin may experience breakouts and should monitor their skin's response carefully during the first few weeks of use.

Photosensitivity is not typically associated with resveratrol or ferulic acid; however, any skincare routine should include daily sun protection. If you notice increased sensitivity to sunlight, burning, or unusual pigmentation changes after starting this product, discontinue use and consult a healthcare professional.

When to seek medical advice: Contact your GP or a dermatologist if you experience:

• Severe or persistent skin irritation that does not resolve within 48 hours of discontinuation

• Signs of allergic reaction, including widespread rash, swelling (particularly of the face, lips, or tongue), or difficulty breathing

• Worsening of pre-existing skin conditions such as rosacea, eczema, or psoriasis

• Any unexpected or concerning changes in your skin's appearance

If you develop symptoms suggestive of anaphylaxis (a severe allergic reaction), such as difficulty breathing, swelling of the throat, or feeling faint, seek emergency medical attention immediately by calling 999 or attending your nearest A&E department.

If you experience any suspected side effects, you can report them via the MHRA Yellow Card Scheme at yellowcard.mhra.gov.uk.

Who Should Avoid This Skincare Product?

Certain individuals should exercise caution or avoid using The Ordinary Resveratrol and Ferulic Acid serum altogether. Pregnant and breastfeeding women should consult their GP or midwife before using cosmetic products containing active botanical compounds, as safety data for topical resveratrol during pregnancy and lactation is limited. While systemic absorption from topical application is likely minimal, a precautionary approach is advisable.

Individuals with known allergies to grapes, berries, or related plants may theoretically be at increased risk of allergic reactions to resveratrol. Similarly, those with sensitivities to grains might theoretically react to ferulic acid, though cross-reactivity is not well established. If you have a history of contact dermatitis or multiple skincare allergies, consider patch testing and consulting a dermatologist before trying new products.

People with active skin conditions should seek professional advice before use. This includes:

• Rosacea: The active ingredients may trigger flushing or worsen inflammation

• Perioral dermatitis: Adding new products can exacerbate this condition

• Active eczema or psoriasis: Application to inflamed skin may cause further irritation

• Severe or cystic acne: Monitor for potential worsening of breakouts

Those currently using prescription skincare treatments, particularly retinoids (tretinoin, adapalene), should discuss compatibility with their prescribing clinician. Combining multiple active ingredients can increase the risk of irritation and compromise the skin barrier.

For children and adolescents, skin may be more sensitive; consider patch testing and simpler formulations. Parental supervision is advisable for younger users.

If you are undergoing treatment for skin cancer or other dermatological conditions, discuss any new skincare products with your dermatologist or oncology team before use, as they may wish to monitor your skin more carefully or recommend specific products compatible with your treatment plan.
