Release Date: May 7, 2025

In Episode 12 of Biohacking Beauty, hosts Amitai Eshel and Anastasia Hojaiva embark on a critical examination of the 12 most viral skincare trends. Their mission is to sift through the hype and provide scientifically-backed insights into each trend's efficacy and long-term benefits. Here's a detailed breakdown of their discussions:

1. Face Ice Baths

[00:30 - 05:55]

Anastasia introduces the concept of face ice baths, a popular trend purported to sculpt, depuff, and tighten the skin. Amitai draws a parallel between facial ice baths and traditional ice baths, highlighting a common misconception:

"Face ice baths and actual ice baths are pretty similar that they have nothing to do with each other."
– Amitai Eshel [02:12]

The hosts agree that while facial ice baths can offer immediate cosmetic benefits like constricting blood vessels for a temporary glow, there are no long-term skincare advantages. Anastasia adds:

"If that look at yourself in the mirror makes you feel better, sure. Have it as a part of your day."
– Anastasia Hojaiva [04:28]

2. Salmon Sperm Facials (PDRN)

[06:00 - 09:21]

The discussion shifts to salmon sperm facials, also known as PDRN (polynucleotides). Amitai explains the historical context and current resurgence:

"They source them from farm-raised fish... but you don't know if they're contaminated."
– Amitai Eshel [06:19]

Anastasia expresses skepticism about the sourcing and effectiveness of these facials, emphasizing the risks associated with contaminants like microplastics and heavy metals present in farmed salmon. They conclude that unless sourcing improves, alternative options like human-derived PRP are preferable.

3. Morpheus 8 (Radio Frequency Microneedling)

[09:27 - 12:01]

Morpheus 8 is critiqued as an overhyped radio frequency microneedling device. Anastasia and Amitai discuss its limitations:

"It creates scar tissue... it's actually temporary swelling and water retention."
– Amitai Eshel [10:27]

They argue that while initial results may appear promising due to swelling, the long-term effects include thinner scar tissue without substantial collagen stimulation. Both hosts agree that the procedure doesn't effectively replace plastic surgery as some proponents claim.

4. Red Light Face Masks

[11:58 - 16:56]

Red light face masks have gained traction on platforms like Instagram, with companies like Omnilux heavily promoting them. Amitai debunks their effectiveness:

"Red light therapy masks aren't as effective long term as a panel that would provide about three times the energy."
– Amitai Eshel [13:37]

They highlight that while the wavelengths used are correct (630-850 nanometers), the LEDs' power is insufficient to deliver meaningful results. Anastasia recommends using red light therapy in conjunction with photoactive ingredients like retinol for enhanced benefits.

5. Retinol Body Cream

[17:49 - 19:57]

Exploring the use of retinol in body creams, the hosts caution against its frequent application:

"Body cream is normally used multiple times a day... retinol is not ideal for that mode of application."
– Anastasia Hojaiva [17:49]

They suggest that integrating retinol occasionally and ensuring proper sun protection can aid in improving skin texture and reducing signs of aging on areas like knees and elbows. Overuse without adequate sunblock, however, can lead to adverse effects.

6. Niacinamide

[20:02 - 24:39]

Niacinamide is lauded for its versatility but scrutinized for potential long-term drawbacks. Amitai explains its role in the NAD cycle:

"Niacinamide can provide short-term benefits... but long-term, it might harm the NAD recycling system."
– Amitai Eshel [20:54]

While beneficial for strengthening the skin barrier and balancing oil production, excessive use can disrupt cellular energy processes. Anastasia advises consumers to check product concentrations and be mindful of possible irritations or breakouts.

7. Hyaluronic Acid

[24:46 - 26:26]

Often hailed as a hydration hero, hyaluronic acid is dissected for its actual benefits:

"It helps lock in moisture and prevent transepidermal water loss."
– Amitai Eshel [25:28]

The hosts emphasize that while it effectively supports skin hydration by retaining moisture on the skin's surface, it doesn't deliver moisture to deeper skin layers. It's best used as a supportive ingredient alongside more potent actives.

8. Glycolic Acid

[26:32 - 28:09]

Glycolic acid is recognized for its exfoliating prowess but warned against due to its potential for skin trauma:

"It's trauma for the skin... results are temporary and can lead to more fragile skin long-term."
– Amitai Eshel [26:32]

They recommend that glycolic acid treatments be limited to professional settings and not overused at home to avoid compromising the skin barrier and increasing susceptibility to damage.

9. Peptides

[30:27 - 37:12]

The conversation delves into the complexities of peptides in skincare. Amitai stresses the importance of peptide length and concentration:

"If you have a peptide that you want to absorb into the cell, it should be four amino acids long, max."
– Amitai Eshel [30:27]

They critique many commercial peptides for being too large to effectively penetrate the skin and for inconsistent formulations across products. Only specific, short-chain neuropeptides show promise in influencing gene expression and reducing biological skin age.

10. PRP (Platelet-Rich Plasma) / Vampire Facials

[34:00 - 37:55]

PRP facials, popularly known as Vampire Facials, are discussed as a potent but misunderstood trend. Amitai explains:

"It is supportive to stimulation of repair... requires consistent treatments for gradual results."
– Amitai Eshel [35:34]

While effective in promoting healing and rejuvenation, especially when combined with microneedling, results are not immediate and require dedication. The hosts caution against opting for subpar or off-brand treatments to ensure safety and efficacy.

11. CO2 Facials

[38:23 - 41:55]

CO2 facials are criticized for their coarse approach to skin oxygenation:

"CO2 masks are a pretty crude way of delivering oxygen to the skin... hyperbaric masks offer a more efficient alternative."
– Amitai Eshel [38:25]

They differentiate between CO2 lasers (a medical procedure) and CO2-infused masks (often spa treatments), highlighting potential risks and advocating for more refined methods like hyperbaric masks that enhance oxygen utilization without the trauma associated with lasers.

Conclusion

In wrapping up, Amitai and Anastasia encourage listeners to question skincare trends, verify scientific backing, and prioritize long-term skin health over fleeting fads. They invite feedback and discussions from the audience, emphasizing the importance of informed skincare choices.

"Understand trends. Don't just follow them and question the source. Check the science."
– Anastasia Hojaiva [42:36]

Key Takeaways:

• Skepticism is vital: Not all trending skincare treatments deliver on their promises. It's essential to research and understand the science behind each trend.

• Long-term vs. short-term benefits: Many popular treatments may offer immediate cosmetic improvements but lack sustainable skincare benefits.

• Ingredient efficacy and formulation: The effectiveness of skincare ingredients often depends on their molecular structure, concentration, and how they're formulated within products.

• Professional guidance: Treatments involving potent acts like glycolic acid or PRP facials should be pursued under professional supervision to minimize risks.

Final Thought:
Embrace skincare biohacks that are scientifically validated and tailored to your skin's needs, ensuring a graceful and enduring aging process.
