Timestamp: [03:38]

Perry introduces a segment on Beauty News, highlighting an article from Cosmetics Design about Shiseido's strategic pivot towards enhancing fragrances in their skincare line.

Perry Romanowski: "The Japanese brand Shiseido is showing growing significance of scent in skincare in enhancing emotional well-being." ([03:38])

Key Insights:

• Emotional Well-Being: Shiseido leverages fragrances to provide psychological benefits, such as stress relief and confidence boosting.

• Consumer Trends: The rise of wellness and self-care trends has positioned fragrances as integral to daily beauty rituals.

• Industry Perspectives: Valerie echoes the sentiment by referencing the concept of "neuro cosmetics," where fragrances influence emotional states.

Valerie George: "There's scientific data about how phytocompounds soothe the brain and create a calming effect." ([05:15])

Conflict with Existing Advice:

The hosts discuss the apparent contradiction between Shiseido's approach and prevalent recommendations to avoid fragrances in skincare, especially for sensitive skin.

Perry Romanowski: "This does seem to conflict with the advice about avoiding fragrance in skincare." ([07:26])

3. Listener Question 1: Environmental and Health Impact of Silicones

Question from Lori:
"Are silicones like amodimethicone and dimethicone environmentally sound? Is there any merit to the concern that silicones are bad for your health or hair follicle?" ([08:19])

Discussion:

• Environmental Concerns:

  • Persistence: Silicones have been detected in remote environments like Antarctica, raising concerns about their environmental footprint.
  • Degradability vs. Biodegradability: While silicones can degrade through non-biological means (e.g., sunlight), they are not readily biodegradable by microorganisms.

• Health and Hair Follicle Safety:

  • Hair Health: Silicones like dimethicone and amodimethicone are deemed safe for hair, providing benefits such as shine, smoothness, and frizz reduction without harming hair follicles.
  • Accumulation: These silicones do not build up excessively on hair when used correctly and are effectively removed through regular shampooing.

Valerie George: "There is no issue when it comes to the health of the hair or the hair follicle because most silicones tend to get rinsed off of the hair or naturally fall off throughout the day." ([12:20])

Conclusion:

The hosts conclude that silicones are generally safe for both the environment and hair health when used responsibly. They emphasize the lack of alarming data concerning their adverse effects.

4. Listener Question 2: Using Both Rinse-Off and Leave-In Conditioners

Question from Kat (Patreon Patron):
"Does using both regular conditioner in the shower and a leave-in conditioner work to control flyaways, or am I expecting too much from conditioners?" ([08:52])

Discussion:

• Simultaneous Use: Valerie explains that using both types of conditioners can be effective if the products are designed for their respective applications.

Valerie George: "If you are still doing both of these products and you're still having flyaways, I would maybe say pull back on the conditioning agents." ([15:36])

• Product Formulation: It's crucial to ensure that the rinse-off conditioner is intended to be rinsed and the leave-in conditioner is formulated to remain on the hair without causing buildup.

• Benefits of Leave-In Conditioners:

  • Humectants: Leave-ins contain humectants like glycerin and hyaluronic acid, which provide additional moisture not achievable with rinse-offs alone.
  • Additional Attributes: Products may offer heat protection, UV protection, or color protection tailored to specific hair needs.

Perry Romanowski: "You can get some of the moisturizing benefits from those humectants that you're not going to get in a rinse off." ([17:28])

Conclusion:

Using both conditioners can enhance hair manageability and appearance, provided the products are compatible and used appropriately. The combination allows for comprehensive conditioning and targeted benefits.

5. Listener Question 3: Evaluating the Dermatologist-Recommended Brand Deafenage

Question from Louisa:
"Does the brand Deafenage seem worth the money, or is it just another brand that providers are pushing on patients to make extra money?" ([20:25])

Discussion:

• Brand Evaluation: Perry and Valerie scrutinize Deafenage's product offerings, noting the lack of unique or superior ingredients compared to mainstream brands.

Valerie George: "I just don't think that there's anything special here that exists in other type products." ([21:26])

• Pricing Concerns: The hosts express skepticism over the high pricing of Deafenage products, suggesting that similar or better-quality products are available from established brands at lower prices.

Perry Romanowski: "I mean, this is a pretty standard cream. And for that amount of money, you could buy a lot of Neutrogena or something for those prices." ([22:55])

Conclusion:

Deafenage appears to offer products comparable to other brands without distinctive advantages, leading the hosts to question the value proposition given its premium pricing.

6. Listener Question 4: Spraying Perfume on Unscented Hair

Question from Mitsuko:
"Can I spray perfume on my unscented hair to keep it smelling fresh?" ([23:06])

Discussion:

• Safety and Efficacy:
  • Regulatory Compliance: Perfumes are formulated with high volatile organic compounds (VOCs) intended to evaporate, ensuring they don't leave heavy residues on surfaces like hair.
  • Application Differences: While perfumes are designed for skin application with appropriate solvent ratios, using them directly as hair products can lead to residue and potential styling issues.

Perry Romanowski: "Perfumes have what is called a high volatile organic content. They have a lot of solvents in them that when you spray the perfume on whatever surface you're going to spray it on, the carrier in, the perfume evaporates into the air." ([24:24])

• Product Formulation: Perfumes regulate their VOC content to optimize scent without overwhelming residues, unlike hair products that may require different formulations.

• Recommendations:

  • Use Designed Products: It's advisable to use fragrances specifically formulated for hair to avoid unwanted buildup or negative interactions with hair products.
  • Application Tips: Light spritzing of perfume on hair can impart fragrance without significant residue, but caution is advised to maintain hair health and appearance.

Perry Romanowski: "I think it's perfectly acceptable for you to take your perfume, especially if you love the smell and your hair and scalp are stinky, which it's normal." ([26:45])

Conclusion:

Spraying perfume on hair is generally safe if done sparingly, but using products specifically designed for hair fragrance is preferable to ensure optimal results without compromising hair health or aesthetics.

7. Listener Question 5: The Importance of Exfoliation vs. SPF

Question from Jennifer:
"Is exfoliation just as important as using SPF for maintaining youthful skin?" ([28:25])

Discussion:

• SPF Significance:
  • Skin Protection: SPF is critical in shielding the skin from ultraviolet (UV) radiation, which can cause premature aging, hyperpigmentation, and increase the risk of skin cancer.

Valerie George: "SPF is very important, and it is key to maintaining a youthful, soft, supple appearance in skin." ([30:07])

• Exfoliation Benefits:
  • Skin Appearance: Exfoliation removes dead skin cells, leading to immediate improvements in skin texture and appearance.
  • Long-Term Effects: Regular exfoliation can prevent clogged pores, reduce breakouts, and enhance the effectiveness of moisturizers by removing the barrier of dead cells.

Unknown Speaker: "Every person needs to be exfoliating if they care about a youthful look." ([33:53])

• Potential Downsides of Exfoliation:
  • Increased UV Sensitivity: Removing the top layer of skin cells can make the skin more susceptible to UV damage, emphasizing the need for diligent SPF use post-exfoliation.
  • Skin Irritation: Over-exfoliation or using harsh exfoliants can damage the skin barrier, leading to irritation and accelerated aging.

Valerie George: "You have to be wearing SPF wherever you exfoliate if you are using acids." ([36:03])

Conclusion:

While SPF is indispensable for long-term skin protection and cancer prevention, exfoliation plays a crucial role in maintaining skin health and appearance. Both practices are complementary, and their combined use, along with consistent SPF application, is essential for youthful and resilient skin.

8. Final Thoughts and Recommendations

The episode underscores the balanced approach required in skincare routines, emphasizing that neither exfoliation nor SPF should be neglected. The hosts advocate for informed product choices, understanding ingredient functionalities, and being mindful of environmental impacts.

Listeners are encouraged to evaluate personal skincare needs, product formulations, and usage habits to optimize their beauty regimes effectively.

Notable Quotes:

• Perry Romanowski: "This does seem to conflict with the advice about avoiding fragrance in skincare." ([07:26])

• Valerie George: "There's a lot of similarities in those products, especially that particular one did not have any cationic surfactants that would be irritating." ([14:49])

• Unknown Speaker: "SPF is going to protect you in the long run. And yes, it protects you from cancer." ([34:38])
