Release Date: August 4, 2025

Introduction

In this insightful episode of the Naked Beauty podcast, host Brooke DeVard sits down with Desiree Stordahl, the Senior Research and Education Manager at Paula’s Choice. The conversation delves deep into the science behind skincare, exploring effective ingredients, personalized routines, and the importance of activism and representation in the beauty industry.

Guest Background: Desiree Stordahl

Desiree shares her journey into the beauty industry, highlighting her personal struggles with acne and the extensive research she undertook to find effective skincare solutions. “[It] wasn’t a clear-cut career path,” Desiree explains ([05:19]). Her passion for understanding skincare ingredients led her to her current role, where she focuses on educating consumers and developing research-backed products at Paula’s Choice.

Understanding Key Skincare Ingredients

1. Peptides ([21:28] - [22:53])

Peptides are small chains of amino acids that play a crucial role in maintaining skin health. Desiree emphasizes their versatility in targeting various skin concerns:

“Peptides can help with brightening, firming, and reducing wrinkles. They’re also preventative, helping to keep skin strong over time” ([21:28]).

She warns against expecting peptides to provide dramatic changes like a facelift but acknowledges their significant role in supporting collagen and elastin.

2. Retinol ([22:55] - [24:05])

Retinol is hailed as a powerhouse ingredient for its multifaceted benefits:

“Retinol is the generalist. It helps with skin renewal, wrinkles, discolorations, and even has anti-acne properties” ([22:55]).

Desiree advises starting with lower concentrations, especially for those new to retinol, and notes her personal experience of achieving noticeable results within weeks.

3. Niacinamide ([24:21] - [26:07])

Niacinamide, a form of Vitamin B3, offers multiple skin benefits, particularly for those with oily skin:

“Niacinamide can tighten enlarged pores, brighten skin, and reduce inflammation. It’s a true workhorse in skincare” ([24:21]).

Desiree recommends Paula’s Choice 20% Niacinamide Booster for its effectiveness, suggesting those with sensitive skin may start with a 10% concentration.

4. AHAs and BHAs ([27:25] - [32:26])

Desiree differentiates between Alpha Hydroxy Acids (AHAs) and Beta Hydroxy Acids (BHAs):

“AHAs are best for normal to dry, sun-damaged skin, while BHAs are ideal for oily and acne-prone skin” ([27:25]).

She explains that BHAs are oil-soluble and penetrate pores more effectively, making them suitable for treating blackheads and breakouts. Additionally, she highlights the importance of pH levels in ensuring these acids are both effective and gentle on the skin.

5. Vitamin C ([32:32] - [36:14])

Vitamin C is celebrated for its antioxidant properties and skin-brightening effects:

“Vitamin C is a powerful antioxidant that brightens skin and combats wrinkles. Stability is key—airtight, opaque packaging is essential” ([32:32]).

Desiree advises using Vitamin C products within three months of opening and pairing them with ferulic acid and Vitamin E to enhance stability and efficacy.

6. Sunscreen ([36:43] - [38:58])

Sunscreen remains a cornerstone of effective skincare:

“Sunscreen is the number one thing that ages skin. It’s essential for every skin type, rain or shine” ([36:43]).

She recommends using SPF 30 to 50 and emphasizes the importance of reapplying, especially when exposed to direct sunlight. Desiree also notes the advancements in sunscreen formulations that prevent white casts and offer more pleasant textures.

Personalized Skincare Routines

Desiree advocates for tailoring skincare routines to individual needs:

“Do what works for you. A routine that’s effective for one person may not be for another” ([40:44]).

She emphasizes that skincare is not one-size-fits-all and encourages listeners to adjust their routines based on skin type, concerns, and hormonal changes.

Career Journey and Passion for Research

Desiree recounts her transition from sales and marketing to research at Paula’s Choice, driven by her passion for skincare science:

“I showed Paula how passionate I was and my willingness to learn, even without a cosmetic chemistry background” ([18:31]).

Her dedication was recognized through multiple interviews, ultimately leading to her role in product development and consumer education.

Activism and Representation in Beauty

The conversation addresses the critical role of diversity and representation in the beauty industry:

“Representation holds a special place in my heart. It’s about showing solidarity and valuing every skin tone” ([45:36]).

Desiree discusses ongoing efforts at Paula’s Choice to improve inclusive hiring practices and ensure that marketing materials authentically represent all consumers. She highlights the importance of open dialogues and listening to marginalized voices to drive meaningful change.

Skincare During Life Changes

Pregnancy and Skincare ([10:11] - [50:35])

Desiree shares how pregnancy positively affected her skin but also discusses the challenges faced postpartum with hormonal acne:

“During pregnancy, my skin thrived, but postpartum hormonal changes led to unexpected cystic acne” ([10:11]).

She underscores the necessity of adjusting skincare routines during significant hormonal shifts and the importance of consulting with healthcare professionals about ingredient safety.

Product Favorites and Recommendations ([50:40] - [56:31])

Desiree highlights her top skincare and makeup products:

• Paula’s Choice BHA Liquid Skin Perfector: A top performer for treating breakouts and improving skin texture.
• 20% Niacinamide Booster: Highly effective for tightening pores and brightening skin.
• Lip and Body Balm: Renowned for its rich hydration.
• Cosrx Pimple Patches: Ideal for preventing blemish picking.
• Mac Water Weight Studio Foundation with SPF 30: A favorite for its lightweight feel and sun protection.
• Kosas Cream Blush and Fenty Beauty Senna Lip Paint: Praised for their durability and clean formulations.

Desiree emphasizes the balance between clean ingredients and effective formulations, ensuring that makeup products are both skin-friendly and performance-oriented.

Trends and Opinions

Desiree critiques certain beauty trends that lack scientific backing:

“Facial massage devices like Face Gym can be harsh on the skin. It’s important to use evidence-based practices” ([53:37]).

She advises listeners to use common sense and judgment when exploring new beauty trends, prioritizing their skin’s health over fads.

Final Thoughts: What Makes You Feel Most Beautiful ([56:42] - [57:31])

Desiree concludes by reflecting on the deeper aspects of beauty:

“True beauty comes from within—compassion, empathy, and kindness” ([56:42]).

She emphasizes that while skincare and makeup are valuable, they should complement the internal qualities that truly define beauty.

Key Takeaways

1. Adapt Your Skincare to Your Cycle: Recognize how hormonal changes, such as menstrual cycles and pregnancy, impact your skin and adjust your routine accordingly.

2. Tailor Solutions for Oily Skin: Utilize clay and charcoal masks, choose lightweight gel formulations, and avoid harsh cleansers to manage oiliness effectively.

3. Choose the Right Exfoliants: Understand the differences between AHAs and BHAs, and ensure products are within the proper pH range for optimal effectiveness and gentleness.

4. Consistent Ingredient Use is Beneficial: Beneficial skincare ingredients remain effective without the need for frequent changes, similar to how a balanced diet consistently supports health.

5. Personalization Over Rigid Routines: Skincare should be personalized. What works for one person may not work for another, and it's essential to listen to your skin's needs.
