REAL PEOPLE

Cephy D. Verified buyer

"I have been using TO BE CLEAR for 1 month. I have very sensitive skin, but it doesn't cause any pain or inflammation. It exfoliates gently. My skin feels so smooth and clean afterwards, like nothing I’ve experienced before."

Mayoma D Verified buyer

"After using 4.5.6 Skin for a month, I noticed the hyperpigmentation on my skin finally starting to fade. I will keep using this product, until hopefully one day my face is clear, and will come back for another review. About to order my second bottle now!"

Laura E Verified buyer

“Green Bae cured my skin from acne. It is so gentle and yet very effective to clean all dirt and makeup. I love the fresh fragrance and detoxifying effect!!”

FAQ

How does the 4.5.6 Skin customisation process work?

Our products are researched, developed. Once you’ve taken the Skin Quiz, our algorithm determines the best-suited formulation for you. After that, your bespoke formulation(s) will be freshly made-to-order by our skin experts, and swiftly delivered to your door, and customised in our proprietary laboratory located in the heart of the French Cosmetic Valley. You can find us on Google Maps here.

Are your products 100% natural, organic, or vegan?

We are 100% Good Face Project approved, Sephora and Ulta Beauty Clean. We use 90% of natural, organic biodynamic ingredients combined with science-backed, lab-made ingredients for maximum effectiveness.

When can I expect to start seeing results from my products?

How quickly you see results will depend on consistency with your skincare routine. We’ll never promise miracles (no one should), but with commitment, you will see results from up to 1-month.

Are your products cruelty-free?

Absolutely. All our products are cruelty-free.

Is fragrance used in your products?

We offer two options; with or without fragrance. Any fragrance we may use has been legally-tested hypoallergenic, and proven to be allergen-free. For those with highly sensitive skin, we recommend a patch test on the inner arm a few days prior to face application.

Why the name ‘4.5.6 Skin?’

We cater our products, research, and development exclusively to darker skin tones ; phototypes 4, 5, and 6 on The Fitzpatrick Scale. That’s why we thought it only right to wear our philosophy on our sleeves, so to speak—and name our melanin-centric brand, 4.5.6 Skin.

Who manufactures 4.5.6 Skin?

Our products are researched, developed, manufactured, and customised in our proprietary laboratory located in the heart of the French Cosmetic Valley. You can find us on Google Maps here.

Can I get samples before I purchase the product?

Since our formulations are tailored to your specific needs and freshly made-to-order, we’re currently unable to offer samples. For more information, contact our team at hello@456skin.com, and we’ll ensure your formulation is the best fit for you.

What’s your return policy, and what are my options if I'm not 100% satisfied with my products?

We stand by our products with a 100% satisfaction guarantee that covers your order within 30-days of shipment. If you’re not completely satisfied with your products, you can either receive a one-time complimentary formula adjustment, or return your order for a full refund. Contact us at hello@456skin.com with your order number for the next steps.
