Featured Ingredient

Coffee Arabica Silverskin Extract

What it is

Coffee Silverskin is the thin, protective outer layer of the coffee bean that is naturally released during roasting. At TEPI® Naturals, we upcycle this byproduct into a high-performance skincare ingredient.

What it does

Naturally rich in antioxidant polyphenols and containing naturally occurring caffeine, it helps support the skin's antioxidant defense while contributing to overall skin comfort and nourishment.

Why we use it

This ingredient sits at the heart of our brand. It represents our commitment to thoughtful upcycling, sustainability, and using nature's overlooked materials in meaningful ways. We use the whole extract — not an isolated compound — so its full profile of polyphenols, caffeine, and trace elements works together as a complete system.

The sent of this lotion lasts even after being in my hot car.

Hi Tracy, we're thrilled to hear you love the lasting scent of our Beach Bum Body Lotion! Thank you for sharing your experience.

LOVE IT !!!

OBSESSED with Lotions and Facial Serum!!!

Hi Margorzata, we're so happy to hear you love the RadiantBoost Serum! Thank you for your wonderful feedback and for choosing Tepi Naturals. Stay radiant!

Love Tepi!

Amazing vitamin c serum. Smells delicious and is potent on skin without being overly harsh. You feel it working but skin doesn’t become irritated and red compared to others I’ve tried. Greatly improved my skin.

Hi Anne,
Thank you so much for this lovely review! We’re so happy you’re loving the RadiantBoost™ Vitamin C serum. ❤️
It makes us smile that you can actually feel it working, but your skin stays calm and happy — that’s exactly how we designed it, especially for sensitive or sensitive-leaning skin. And yes, that delicious smell is pretty addictive, isn’t it?
Since you’re getting such great results with vitamin C during the day, we wanted to recommend our Original Antioxidant Serum for nighttime. It’s formulated with a different blend of antioxidants and is especially soothing and repairing while you sleep. Many of our customers use RadiantBoost in the morning for protection and the Original at night to renew and recover from the day. They make the perfect duo. If you haven’t tried it yet, we think you’d really love it.
Thank you again for taking the time to share your experience. It truly means a lot to us.
If you ever want to chat about your routine or need any recommendations, just hit reply — we’re here!
Wishing you the best skin of your life,
Steve and Brent

Excellent Serum!! RadiantBoost Vitamin C + Coffee Silverskin Hydrating Serum

I developed some skin damage spots on my face from a lot of sun exposure when I was growing up. The different pharmaceuticals my doctor gave me to try over the years do not work at all to lighten the spots (and they're synthetic and filled with junk).
I used a high potency Vitamin C serum that actually worked to lighten the spots, but the owner retired and went out of business about 6 years ago.
I met the owner of Tepi Naturals at a craft show in December and decided to try the RadiantBoost Vitamin C + Coffee Silverskin Hydrating Serum. It is great!! My spots have now lightened up and my skin feels hydrated and has a very nice glow. I now subscribe to the Serum. I highly recommend this product if you need to lighten spots, or you want a beautiful radiance to your skin.
Thank you Tepi Naturals! Your RadiantBoost Vitamin C + Coffee Silverskin Hyrdating Serum is great!

Hi Mary,
Thank you so much for taking the time to share this—it really means a lot to us.
We’re especially grateful that you gave RadiantBoost® a chance after everything you’ve tried over the years. Hearing that your skin is looking more radiant and feeling healthier is exactly why we started TEPI® Naturals in the first place.

And honestly… the coffee part of this is a pretty big deal.

There’s some incredibly promising research around coffee-derived ingredients—especially the antioxidant compounds found in Coffee Silverskin—and it’s what first got us excited about bringing this into skincare. We wish we could share everything we’ve learned along the way, because it’s genuinely fascinating—but we also want to be thoughtful about how we talk about it. We’re not a drug company, so we focus on creating well-formulated products and letting real experiences—like yours—speak for themselves.

That’s why your feedback means so much. It helps tell the story in a way we simply can’t on our own.

And we always say—skincare that feels good gets used, and that consistency is what really supports your skin over time. We’re so glad RadiantBoost® has become part of your routine.

If you ever want to complement it, our Original Coffee Silverskin Serum is a great evening pairing for continued support.

Thank you again for your trust and for sharing your story—we’re truly grateful to have you with us.

Be Radiant Naturally™

Local small business. Amazing product.

Michal, thank you for the kindness, please let us know if there is anything more we can do to be of serivce. Steve and the Tepi Family
