Summary of "Astaxanthin: Is it BETTER THAN VITAMIN C?| Dr Dray"
Summary of Key Points on Astaxanthin in Skin Care (Dr. Dray)
What is Astaxanthin?
- Astaxanthin is a carotenoid antioxidant found in lobster, salmon, and microalgae.
- It gives seafood its reddish color.
- Known for potent antioxidant properties demonstrated in lab studies (cells in a dish).
Claims vs. Evidence
- Marketed as more potent than vitamin C for brightening, hyperpigmentation, and evening skin tone.
- Lab studies suggest astaxanthin may be better than some carotenoids at scavenging free radicals.
- However, there is no strong clinical evidence supporting its effectiveness in humans, especially when applied topically.
- Stability and skin penetration of topical astaxanthin are not well studied.
- Existing human studies are limited and of low quality (small sample sizes, lack of controls).
Potential Benefits (Mostly from Lab and Animal Studies)
- Antioxidant and free radical scavenging effects.
- Anti-inflammatory properties.
- Immune-boosting effects (shown in mice).
- Possible improvement in skin hydration and wrinkles (based on small, inconclusive studies).
Safety and Risks
- Topical use appears safe and well-tolerated, with no common irritation reported.
- Safety of oral supplements is uncertain; potential risks include:
- Interaction with medications metabolized by the P450 enzyme system.
- Possible inhibition of 5-alpha reductase enzyme, which could cause side effects similar to certain medications (e.g., decreased libido, impotence).
- Not recommended for pregnant or breastfeeding women due to unknown risks.
- Theoretical risk for people with autoimmune diseases because of immune-boosting potential.
- Caution is advised with oral supplements; it is better to obtain antioxidants from diet (vegetables, salmon).
Comparison with Vitamin C
- Vitamin C (L-ascorbic acid) also faces stability challenges but is much better studied.
- Well-formulated vitamin C serums (e.g., Skinceuticals CE Ferulic) have proven benefits.
- There is currently no evidence supporting astaxanthin as superior to vitamin C for skin concerns.
Product Recommendations and Considerations
- Some products contain astaxanthin, such as:
- DHC Astaxanthin Collagen All-in-One Cream
- Paula’s Choice Super Antioxidant Concentrate Serum with retinol
- These products tend to be expensive.
- Dr. Dray plans to try Rovectin Skin Essentials Barrier Repair Face and Body Cream (contains ceramides, fragrance-free, affordable) and may review it.
- For hyperpigmentation, it is best to stick to ingredients with proven efficacy (e.g., hydroquinone, soy).
General Advice
Don’t chase astaxanthin hype without solid evidence. Continue using products and ingredients with demonstrated benefits. Always use sunscreen. Consider diet over supplements for antioxidants.
Key Wellness and Skincare Tips
- Prioritize ingredients with strong clinical evidence for hyperpigmentation and anti-aging.
- Be cautious with antioxidant supplements due to potential risks and interactions.
- Focus on diet-based antioxidants rather than supplements when possible.
- Use stable, well-formulated topical antioxidants like vitamin C serums.
- Avoid supplements during pregnancy, breastfeeding, or if you have autoimmune conditions without medical advice.
- Always apply sunscreen daily for skin protection.
