Antioxidants play a central role in modern skincare, helping to protect the skin from environmental stressors, reduce oxidative damage, and support a healthier, more radiant complexion. Among the many antioxidants available, phloretin has gained attention for its unique properties and potential skin benefits. This article compares phloretin with other popular antioxidants, including vitamin C, vitamin E, ferulic acid, green tea polyphenols, resveratrol, niacinamide, and bakuchiol, to help you decide which antioxidant or combination might be best for your skin concerns and routine.

What is phloretin and how does it work on the skin?

Phloretin is a natural dihydrochalcone found in apple tree leaves and certain other plants. It is closely related to phlorizin, but phloretin is more bioavailable and active in skin tissues. On the skin, phloretin acts as an antioxidant, helping to neutralize reactive oxygen species (ROS) generated by UV exposure, pollution, and other stressors. It also exhibits anti-inflammatory properties, which can support calmer skin and potentially modulate immune responses in the skin. Additionally, phloretin may influence cellular pathways involved in melanin production and photoaging, contributing to a more even skin tone and reduced signs of aging in some contexts.

How phloretin compares to vitamin C

Vitamin C (ascorbic acid) is a cornerstone antioxidant in skincare, renowned for its brightening effects, collagen-stimulating potential, and photoprotection. When comparing phloretin to vitamin C, consider the following:

- Stability: Vitamin C is notoriously unstable in formulations and can degrade with exposure to air, light, and heat. Phloretin, while not immune to degradation, can be formulated in more robust ways in certain derivative forms that improve stability.

- Mechanism: Vitamin C primarily reduces oxidative stress and supports collagen synthesis via stimulation of pro-collagen gene expression. Phloretin primarily scavenges ROS and exerts anti-inflammatory actions, with potential modulatory effects on skin signaling pathways.

- Synergy: Some formulations combine vitamin C with ferulic acid to enhance stability and efficacy. Phloretin may be used in combination with other antioxidants to broaden protective coverage, particularly in mitigating inflammation.

- Sun protection: Vitamin C provides some photoprotection when used consistently, but it does not replace sunscreen. Phloretin complements sun protection by reducing oxidative damage after UV exposure and helping to calm inflamed skin.

Bottom line: If your goals include brightening and collagen support, vitamin C is a strong choice. Phloretin offers complementary benefits, especially in anti-inflammatory and ROS-scavenging actions, and can be advantageous in multi-ingredient antioxidant systems.

How phloretin stacks up against vitamin E and ferulic acid

Vitamin E (tocopherol) is fat-soluble and stabilizes cell membranes while providing antioxidant protection, particularly in lipid-rich environments like sebum. Ferulic acid is a phenolic antioxidant that dramatically stabilizes vitamins C and E and enhances their photoprotective effects.

- Stability and synergy: Ferulic acid is well-known for increasing the effectiveness and stability of both vitamins C and E when used together. Phloretin's stability profile can be favorable in certain formulations, but it does not have the same well-established trio synergy as vitamin C + ferulic acid + vitamin E.

- Targeted actions: Vitamin E protects lipid-rich skin areas and helps reduce transepidermal water loss, contributing to barrier support. Ferulic acid broadens antioxidant coverage and helps preserve the activity of other antioxidants. Phloretin provides anti-inflammatory benefits and ROS scavenging which can complement lipid protection and barrier health.

- Use case: For a skin routine focused on overall antioxidant network and photoprotection, a combination of vitamin C, vitamin E, and ferulic acid is a proven, widely used approach. Adding phloretin can offer additional anti-inflammatory and ROS-control benefits, especially for sensitive or inflamed skin.

Bottom line: Ferulic acid and vitamin E deliver strong, well-established photoprotective effects and barrier support. Phloretin adds anti-inflammatory and ROS-scavenging benefits that can enhance a multi-antioxidant strategy, particularly in inflamed or reactive skin.

Phloretin vs green tea polyphenols and resveratrol

Green tea polyphenols, especially epigallocatechin-3-gallate (EGCG), are potent antioxidants with anti-inflammatory properties. Resveratrol is another polyphenol with scavenging abilities and potential anti-aging signaling effects.

- Green tea polyphenols: EGCG is effective in neutralizing ROS, reducing UV-induced damage, and supporting immune responses in skin. EGCG also has anti-melanogenic properties, which can help with pigmentary concerns. Phloretin and EGCG can complement each other, offering a broader spectrum of antioxidant actions and possible synergistic effects in certain formulations.

- Resveratrol: Known for activating sirtuin pathways and supporting cellular resilience, resveratrol provides antioxidant and anti-inflammatory benefits. Its stability can be a concern, but modern formulations improve its bioavailability. Phloretin can pair with resveratrol to expand antioxidant coverage and potentially address more inflammatory pathways.

Bottom line: If you seek a robust, multi-faceted antioxidant system, combining phloretin with green tea polyphenols or resveratrol can provide complementary mechanisms. This approach may be especially helpful for aging concerns and inflammation-prone skin.

Phloretin in relation to niacinamide and bakuchiol

Niacinamide (nicotinamide) is a versatile ingredient addressing barrier function, inflammation, pigmentation, and sebum regulation. Bakuchiol is frequently touted as a natural retinol-like alternative that supports cell turnover and collagen production.

- Niacinamide: While not a classic antioxidant in the same way as vitamin C or ferulic acid, niacinamide reduces oxidative stress indirectly by improving barrier function and reducing inflammation. It stabilizes the skin environment, which can enhance the effectiveness of antioxidants like phloretin.

- Bakuchiol: Bakuchiol provides retinol-like benefits with a gentler profile, supporting collagen synthesis and turnover. Its antioxidant properties are present but not as potent as dedicated antioxidants. Phloretin can be used alongside bakuchiol to bolster antioxidant protection while bakuchiol works on renewal processes.

Bottom line: For a calm, resilient skin barrier with anti-aging benefits, place niacinamide in the routine alongside phloretin. If you want renewal benefits similar to retinol, combine bakuchiol with phloretin for both turnover and oxidative protection.

Practical guidance: building an antioxidant skincare routine with phloretin

- Start with a clean base: Use a gentle cleanser and a hydrating routine that maintains skin barrier integrity.

- Layering order: Apply lighter, more water-based products first, followed by heavier emulsions or creams. If using a serum with phloretin, allow it to absorb before applying moisturizers.

- Combine with complementary antioxidants: Consider pairing phloretin with vitamin C (in the morning) and ferulic acid for added stability and photoprotection. In the evening, a combination with green tea polyphenols or resveratrol can provide ongoing antioxidant support.

- Add barrier-supporting ingredients: Niacinamide can be used daily to strengthen the barrier, while ceramides and glycerin help retain moisture and improve texture.

- Sun protection: Always use broad-spectrum sunscreen during the day. Antioxidants work best when paired with effective sun protection to minimize UV-induced ROS.

- Patch testing: Introduce phloretin gradually, especially if you have sensitive or reactive skin. Start with a lower concentration and monitor for irritation.

Targeted concerns: who may benefit most from phloretin

- Sensitive or inflamed skin: Phloretin's anti-inflammatory properties may help reduce redness and irritation, especially when used in combination with barrier-supporting ingredients.

- Pigmentary concerns: Some evidence suggests phloretin can influence pathways related to pigmentation; when used with other brightening agents, it may contribute to a more even tone.

- Aging and photodamage: By scavenging ROS and supporting anti-inflammatory responses, phloretin can help mitigate some signs of photoaging, particularly when used as part of a broader antioxidant strategy.

Potential limitations and considerations

- Evidence scope: While phloretin shows promise in laboratory and some clinical contexts, it may not have as extensive a track record as better-studied antioxidants like vitamin C or ferulic acid.

- Formulation challenges: The stability and bioavailability of phloretin depend on the formulation. Work with reputable products to ensure proper delivery and potency.

- Individual variability: Skin type, sensitivity, and existing skincare ingredients influence how phloretin works for you. Personalizing your routine is key.
