Retinal, or retinaldehyde, has become a star ingredient in the skincare world. It's the form of Vitamin A that sits just one conversion step away from retinoic acid—the active form your skin actually uses. This means it works up to 11 times faster than traditional retinol, often with less irritation. If you're looking to add this powerful serum to your routine, here's a guide to the best places to find it in the United States.
1. Ulta Beauty: Your One-Stop Shop
Ulta Beauty is a prime destination for retinal serums, offering both high-end and accessible options. It's an excellent starting point because you can find a few standout brands that specialize in this ingredient.
-
Peach & Lily Retinal For All Renewing Serum: This is a favorite for those concerned about irritation. It pairs a potent 0.1% encapsulated retinal with ectoin, a soothing ingredient that helps protect the skin barrier. It's praised for delivering clinical results—like a 50% reduction in the appearance of fine lines—while being gentle enough for sensitive skin. You can find this exclusively at Ulta.
-
Rodan + Fields Redefine Intensive Renewing Serum: For a more potent option, Rodan + Fields offers a serum with Retinal-MD™ Technology. This is a powerful retinoid that's still available without a prescription. Ulta is one of the primary retailers for this brand, making it readily accessible.
2. Costco: The Viral K-Beauty Find
Believe it or not, Costco has become a hotspot for retinal serums. The wholesale retailer is currently carrying KSECRET SEOUL 1988 Serum: Retinal Liposome 2% + Black Ginseng, a product that has gone viral on platforms like TikTok.
This is a notable option because it's an exclusive Costco deal, offering a 50ml double set for $35.99. The formula uses liposome technology to help deliver the retinal effectively while minimizing irritation, and it includes black ginseng for its antioxidant properties. It has been clinically shown to improve skin tone, fine lines, and texture within 14 days.
3. Amazon: Convenience and Variety
Amazon is, of course, a massive marketplace for skincare, and it carries several popular retinal serums. It's a convenient option if you have a specific product in mind.
-
Medik8 Crystal Retinal: This is a cult-favorite retinal serum, though on Amazon, you'll primarily find it through third-party sellers . It's often available in a progression of strengths (from 1 to 20), with the highest strengths recommended for experienced users.
-
MEDITHERAPY Retinal Skin Booster Serum: This is a K-beauty option that's highly ranked on Amazon. It combines retinaldehyde with niacinamide to target fine lines, firmness, and radiance. It's a more affordable entry point, often priced around $19.9.
4. Dermstore: Expert Curated
For a selection that's more curated by skincare experts, Dermstore is a top choice. This is an authorized retailer for premium brands and is a key destination for Medik8. In fact, the brand's most powerful serum, Crystal Retinal 20, is exclusively available in the USA through Dermstore, and it requires an online consultation before purchase to ensure it's right for your ski.
5. Drugstores and Mass Retailers
While retinal is a more advanced ingredient, you can still find it at traditional drugstores and mass retailers like Target. Look for these brands:
-
Naturium Retinaldehyde Cream Serum: Available at Target and other mass retailers, this serum comes in three strengths (0.05%, 0.1%, and 0.15%). This is perfect for beginners who want to start with a lower concentration and work their way up as their skin builds tolerance.
-
Avene RetrinAL 0.1 Intensive Cream: Found in drugstores, this is a gentle, fragrance-free option formulated for sensitive skin.
Final Tip: Starting Your Retinal Journey
Retinal is potent, so a common piece of advice from dermatologists is to start slowly. Begin by applying it once or twice a week in the evening, and gradually increase the frequency as your skin adjusts. And, as always, consistent use of a broad-spectrum SPF 30 sunscreen during the day is non-negotiable.
Your best bet will depend on your budget and how much guidance you want. For a gentle, beginner-friendly option, try Ulta or Target. If you're looking for the highest potency, Dermstore or Costco have you covered.
