Does Your Skincare Actually Sink In? The Truth About Product Penetration with RE+NU Naturals

Ever wondered if your RE+NU Naturals skincare products are truly being absorbed by your skin? It's not just about the price tag or the promised results—let’s dive into the reality of ingredient penetration and what it takes for those claims to hold true!

First, let’s understand how our skin, the largest organ of our body, functions as a protective barrier. It’s composed of three layers:

Epidermis: The top layer, known as the waterproof barrier, contains the stratum corneum, which is made up of dead skin cells arranged like tiles on a roof, held together by fatty acids.
Dermis: This middle layer houses elastin, collagen, blood vessels, hair follicles, and sweat glands.
Hypodermis: The innermost layer, composed of fat and connective tissue.

Now, here’s an important fact: skin is not a sponge! Most topical products, including those from RE+NU Naturals, primarily work on the surface, in the epidermis, and only a small percentage can penetrate deeper to reach the dermis. As board-certified dermatologist Dr. Shereene Idriss states, the stratum corneum acts as a formidable barrier designed to keep unwanted substances out.

Factors Affecting Absorption

Several elements influence how well your RE+NU Naturals products penetrate:

Molecule Size: Smaller molecules can pass through the stratum corneum more easily. Our formulations are designed to include such ingredients for better absorption.
Lipophilicity: Ingredients that love oil can integrate better with the skin's lipid-rich environment. Many RE+NU Naturals products harness this property for effective results.
Concentration: Higher concentrations of active ingredients may enhance penetration, which is a focus in our product development.
Formulation: The type of product (serum, cream, ointment) affects ingredient delivery. RE+NU Naturals offers a variety of formulations to suit your needs.
Skin Condition: Compromised barriers from dryness or irritation can allow for greater absorption. Our products aim to nourish and restore the skin barrier.
Application Technique: A gentle massage can increase blood flow and improve contact time, enhancing absorption.

Ingredients That Actually Penetrate

While many ingredients stay on the surface, some in RE+NU Naturals products can indeed penetrate the stratum corneum:

Small Molecular Weight Ingredients: Hyaluronic acid, certain peptides, and some vitamins (like Vitamin C) in our formulations can penetrate effectively.
Vitamins: Vitamin A derivatives (like retinyl esters), Vitamin E, and niacinamide are included in our products for their beneficial properties and ability to reach deeper layers.
Lipophilic Ingredients: Retinoids are oil-soluble and penetrate well; you can find these in our targeted treatments.
Chemical Exfoliants: AHAs (glycolic, lactic acid) and BHAs (salicylic acid) help loosen bonds between skin cells, improving penetration. Our exfoliating products are designed with this in mind.
Enzymes: Ingredients like papain and bromelain can enhance penetration by breaking down proteins in the upper skin layers.
Squalane: This highly emollient lipid, found in some of our products, is easily absorbed.
Glycolic Acid: A potent AHA that penetrates effectively and is featured in our formulations.
Tamanu Oil: Known for its penetrating properties, this oil is included in our nourishing products.
Essential Oils: Some, like lavender and citrus oils, contain compounds that may enhance penetration and are thoughtfully incorporated into our formulations.

Carrier systems, such as liposomes or microencapsulation, are also used in our products to help deliver ingredients deeper into the skin.

Tips for Maximizing Product Absorption

You can optimize your skincare routine with RE+NU Naturals to improve absorption:

Cleanse Properly: Start with a clean base using our Lactic Acid Cleanser to remove dirt and oil that can hinder absorption.
Exfoliate Regularly: Gentle exfoliation with our products removes dead skin cells, allowing for better penetration of subsequent treatments.
Apply in the Right Order: Use products from thinnest to thickest; apply our lightweight serums before heavier creams to maximize absorption.
Use Targeted Treatments: Our serums and concentrates are formulated with higher concentrations of active ingredients designed for better penetration.
Consider Occlusives: A layer of an occlusive product, like RE+NU Luxury Beauty Oil, can seal in moisture and enhance absorption.
Be Patient and Consistent: Results take time, so consistent use of our well-formulated products is key.

The Takeaway

Your skin may be a powerful barrier, but understanding the factors that affect ingredient absorption can help you make informed choices about your RE+NU Naturals skincare routine. By maximizing the benefits of our products, you can achieve the glowing skin you desire.

An Important Update from the Founder of RE+NU Naturals on Pricing Transparency and the Impact of Tariffs

Apr 10, 2026

by Bonnie Giangrande

minute read

Hello, everyone! As the founder of RE+NU Naturals, I believe in the importance of transparency, especially concerning pricing. I want to share with you a critical update on the evolving landscape of the international cosmetic industry, specifically regarding tariffs, consumer price hikes, and what we’re facing as a business.

The Numbers Nobody Is Explaining to You

Since the implementation of Donald Trump’s April 2, 2025, “Liberation Day” tariffs, U.S. tariff rates have soared to over 20%—the highest in a century. That’s significant, especially for the U.S. beauty industry, which heavily relies on imported packaging, raw materials, and finished products.

Here's where the math gets uncomfortable:

China, a major supplier for cosmetics and packaging, now faces tariffs of up to 55%.
South Korea, a leading source for K-Beauty products, is contending with tariffs of 25% or higher.
France and Italy, our go-to countries for fine fragrances and prestige skincare, are both facing tariffs over 20%.

Additionally, BASF, one of the world's largest ingredient suppliers, just announced price increases on *amines used in personal care formulations effective April 6th, 2026. This affects products ranging from shampoos to lotions.

Packaging costs are projected to rise 5%-10% industry-wide, compounded by simultaneous increases in ingredient costs, freight, compliance, and legal fees.

Industry analysts are projecting a retail price increase of 10%-15% across all cosmetics and personal care products.

It’s Not Just Indie Brands Anymore

When we first looked at this issue, we focused on independent brands faced with a unique vulnerability due to tariff shocks. However, major cosmetic corporations are not immune.

Procter & Gamble has raised prices, while Estée Lauder disclosed $100 million in profitability challenges linked to tariffs. Their response includes cutting up to 7,000 jobs and reevaluating pricing across their brands.

E.l.f. Beauty E.l.f. Beauty, the brand that built its entire identity on accessible price points to a mass market, raised prices by $1 per SKU starting in August 2025.
On a product that retailed for $10, it’s only a 10% increase, but on a $3 product, that’s a 33% increase. The CEO, to his credit, was remarkably transparent about the reason, and the brand communicated directly with consumers via social media.

The Consumer Backlash Is Building

Consumers are aware of price increases and are not pleased. A Civic Science survey revealed that 29% of beauty shoppers plan to cut back on purchases due to tariff-driven price hikes, and 60% would stop buying cosmetics altogether if prices rose more than 10%.

Many consumers are already buying fewer products or resorting to discounts and cheaper brands. This shift is not just a passing trend; it’s a survival strategy influenced by economic pressures.

What Happens Next?

The honest answer is we still don’t fully know. The tariff landscape is in legal limbo, with multiple challenges underway. If the tariffs are ultimately struck down, brands may receive refunds, but it’s unlikely those savings will reach smaller brands or the consumer.

As we move through 2026, we are closely monitoring pricing trends and actively searching for ways to provide savings for our customers on our website. We understand the impact that rising costs can have, which is why we’ve rolled out several options to help you save:

Loyalty Program: Earn rewards with every purchase to make your shopping experience even more rewarding.
No Box Options: Choose to eliminate excess packaging for a more economical choice at a lower price.
Bundle Options: Save more when you purchase products together in bundles.
Refill Options: Opt for refillable products that reduce waste and lower costs.

We are committed to providing you with the best possible value while maintaining transparency about our pricing. Thank you for being a valued part of the RE+NU Naturals community!

*Amines are nitrogen containing organic compounds that play a significant role in skincare. They are often used as emulsifiers, pH regulators, and conditioning agents

Additional Tips for Glowing Skin:

- Stay Hydrated: Drink plenty of water throughout the day to keep your skin hydrated from the inside out.

- Eat a Balanced Diet: Incorporate plenty of fruits, vegetables, and healthy fats for glowing skin.

- Get Enough Sleep: Aim for 7-8 hours of sleep each night to allow your skin time to repair and rejuvenate. Sleep enhances the production of collagen, which helps maintain skin elasticity and reduces the appearance of fine lines and wrinkles.

- Regular Exercise: Engage in physical activities, even if it is just 15 - 20 minutes a day of walking, to promote circulation, which enhances your skin’s natural glow.
