Smarter Vitamin A: Why Retinaldehyde Works Year-Round

Vitamin A Myths: Debunking the Summer Skincare Rules

You’ve probably heard it before: stop using Vitamin A in the summer. But what if the right form of Vitamin A could actually support your skin through every season?

While traditional retinol and prescription Retin-A may increase sun sensitivity and irritation, Osmosis takes a different approach. We use a clinically supported, non-toxic form of Vitamin A called retinaldehyde, which is sun-safe, non-irritating, and ideal for both professional and at-home use.

Whether you’re booking a facial or updating your daily skincare routine, here’s why retinaldehyde still belongs in your regimen all summer long.

 

What Is Vitamin A and Why Does It Matter?

Vitamin A is one of the most effective ingredients for supporting skin health and addressing visible signs of aging. It promotes a smoother-looking texture, more even tone, and firmer appearance by encouraging natural exfoliation and cell turnover. But not all forms of Vitamin A are created equal.

Traditional forms like retinol and Retin-A can be harsh on the skin, often leading to dryness, flaking, and increased sensitivity. These side effects are especially problematic during the warmer months when heat and sun exposure already challenge the skin barrier. That’s where retinaldehyde comes in.

 

Why We Use Retinaldehyde Instead of Traditional Vitamin A

Retinaldehyde is a more advanced, bioavailable form of Vitamin A. It delivers the same visible benefits as retinol with greater skin compatibility and fewer side effects. Here’s what makes it different:

  • One-step conversion: Retinaldehyde converts directly to retinoic acid within the skin, making it faster and more efficient than retinol or Retin-A.

  • Gentle yet effective: Supports firmer skin and a smoother-looking texture without triggering dryness, flaking, or barrier disruption.

  • Non-inflammatory and well-tolerated: Ideal for sensitive skin types and those new to Vitamin A.

  • Year-round use: Safe to use in the summer and does not increase sun sensitivity.

  • Advanced delivery system: Our patented liposomal delivery technology helps Retinaldehyde absorb deeper into the skin for longer-lasting results.

  • Supports skin resilience: Promotes the appearance of healthy collagen and elastin without stressing the skin.

  • Pregnancy-friendly: Safe for use while pregnant or breastfeeding (always consult your physician).

 

Daily Vitamin A: Correct Preventative Retinal Serum

Osmosis Correct Preventative Retinal Serum is an award winning serum powered by retinaldehyde. Formulated with an enhanced delivery system, this anti-aging serum contains 9 collagen stimulators and 7 potent antioxidants. It promotes a clearer, smoother, more balanced-looking complexion without the dryness or irritation common with other Vitamin A products.

Perfect for daily use, Correct helps improve the appearance of:

  • Rough or uneven texture

  • Fine lines & wrinkles

  • Loss of elasticity

  • Dull, unbalanced skin tone

And yes, it’s sun-safe, making it ideal for daily use!

 

In the Treatment Room: Vitamin A Facial Infusion

For professional use, the Osmosis signature Facial Infusion offers a non-acid, dermal rejuvenation that infuses retinaldehyde deep into the skin using liposomal delivery. Unlike traditional peels or exfoliants, this facial works with the skin to promote long-term health and visible improvements without inflammation.
