What’s the difference between retinoids, retinol, and retinal? Which form is in Firm Revival HydroRetinal Firming Serum?

"Retinoid" is the umbrella term for a family of topical vitamin A derivatives used in skincare, from over-the-counter products to prescription treatments. While all retinoids work by increasing cell turnover and supporting collagen, they differ in potency, how quickly they work, and how they're converted by the skin. For a retinoid to deliver its benefits, it must ultimately convert to retinoic acid (the active form that drives results). Prescription treatments like tretinoin are already retinoic acid, while non-prescription retinoids must first be converted by the skin. The fewer conversion steps required, the more potent and efficient the retinoid. "Retinol" is the most common non-prescription retinoid found in skincare. It requires two conversion steps before becoming retinoic acid, making it an effective option, but slower-acting. "Retinal" (also called retinaldehyde), found in Firm Revival, is the most potent retinoid available without a prescription. Because it requires just one conversion step to become retinoic acid, it can deliver results more quickly and efficiently than traditional retinol. It’s a great option for those who find tretinoin to be too harsh but want a formula more fast-acting and effective than other cosmetic retinol products.

Who is Firm Revival HydroRetinal Firming Serum made for?

Firm Revival is designed for anyone looking to address visible signs of aging, including fine lines, wrinkles, uneven texture, and loss of firmness. Its gentle yet effective formula also makes it a great option for people who are new to retinoids or have experienced dryness, flaking, or discomfort when using retinoids in the past. If you're new to retinoids, we recommend applying Firm Revival 2-3 nights a week, then gradually building up to nightly use as tolerated.

What makes Firm Revival HydroRetinal Firming Serum different from other cosmetic retinal products and prescription retinoids?

Retinoids are considered the “gold standard” in skincare because they're backed by a wealth of clinical data that supports their ability to improve the appearance of fine lines and wrinkles, uneven skin tone, and skin texture. But for many people, incorporating one into their routine can be challenging, as dryness, flaking, and discomfort (often called the “retinal uglies”) can make it difficult to stay consistent. We created Firm Revival to help address this challenge. Formulated with a balance of powerful actives and deeply soothing ingredients, Firm Revival delivers the visible firming and smoothing benefits people want from a retinoid, but in a formula designed to minimize sensitivity and support the skin barrier at the same time. Awarded the National Eczema Association Seal of Acceptance, this hydrating retinal serum is effective enough for experienced retinoid users but approachable enough for people who've never used one before or have been too afraid to start.

I already use tretinoin. Is there any reason to use Firm Revival HydroRetinal Firming Serum?

If your skin can already tolerate tretinoin, great! That said, Firm Revival can still be a great addition to your routine to tackle areas where skin is thinner and tretinoin may be too harsh, like the under-eyes, neck, and chest area.

What is the percentage of retinal in Firm Revival HydroRetinal Firming Serum?

Firm Revival contains 0.05% next-gen retinal: an advanced, hyper-stable retinal with a proprietary multi-phase delivery system that helps maximize efficacy while minimizing sensitivity.

What does “next-gen retinal” mean?

When developing Firm Revival, it was a non-negotiable to create a high-performance formula that delivered the proven benefits of retinal while still being gentle on the skin. To do so, we partnered with a specialized supplier to create our own never-been-used-before retinal delivery system technology. If you're a retinoid nerd, you may have heard of encapsulation, a technology that surrounds retinal in a protective shell to help improve stability and delivery. Our retinal takes that concept one step further. Instead of relying on a single protective layer, our next-gen retinal uses a multi-phase delivery system with various layers and components designed to further stabilize the ingredient, optimize absorption, and provide controlled release over time to help mitigate sensitivity. Think of it like a jawbreaker; it just keeps getting better with every layer.

Should I apply Firm Revival HydroRetinal Firming Serum in the morning or at night?

Firm Revival should be applied only at night on completely dry skin.

Can I use Firm Revival HydroRetinal Firming Serum every day?

While Firm Revival is formulated to be gentle enough for daily use, for new retinoid users, we recommend starting 2-3 times a week and gradually building up to nightly use.

Should I expect an acclimation period with Firm Revival HydroRetinal Firming Serum?

When starting any retinoid, there may be an acclimation period. Firm Revival is formulated to be gentle, but temporary breakouts may occur when starting out. If these don't resolve or if you experience an allergic reaction, please discontinue use and reach out to us at hello@dieuxskin.com.

Can I use Firm Revival HydroRetinal Firming Serum around the eye area?

Yes! Firm Revival is ophthalmologist-tested and has undergone ocular safety testing to evaluate its potential to cause irritation or adverse reactions to the eye area. This means Firm Revival has been deemed safe for use around the eyes, including for sensitive skin and contact lens wearers. As always, everyone’s skin is different, so we recommend patch testing and discontinuing use if any irritation occurs.

Can I use Firm Revival HydroRetinal Firming Serum with Deliverance 3-in-1 Repair Serum?

Yes! After cleansing at night, apply Deliverance, then allow your skin to fully dry before applying Firm Revival. Ordering in this case doesn’t really matter, but since Deliverance has a lighter water-based texture, layering it first can help ensure both serums absorb seamlessly into the skin.

Are there any products or ingredients I shouldn't use with Firm Revival HydroRetinal Firming Serum?

While Firm Revival is formulated to be gentle on skin, we generally recommend avoiding using retinal with anything that might be considered exfoliating, especially if you're new to using it. This includes chemical exfoliants, but also ingredients like azelaic acid, which is a keratolytic exfoliant. Once you've used Firm Revival regularly for at least 8 weeks, you can gradually reintroduce exfoliants once or twice a week (ideally in the mornings when you aren't applying retinal, or alternating nights if you aren't using retinal daily).

Is Firm Revival HydroRetinal Firming Serum safe to use during pregnancy and while breastfeeding?

It is not recommended to use any form of retinoid while pregnant. While all of our formulas are reviewed by a toxicologist, we recommend always consulting your medical provider to make the most informed decisions for your skin.

Why is Firm Revival HydroRetinal Firming Serum yellow?

The yellow color comes naturally from retinaldehyde (retinal), a derivative of vitamin A! Vitamin A molecules naturally absorb blue and green light, which shows up to the eye as the complementary color: a yellow-orange hue!
