Discover Retinal: The Essential Ingredient for Rejuvenated Skin
In the world of skincare, retinal is emerging as a powerful active ingredient with multiple benefits. But what is retinal, and how does it differ from retinol? Let's explore the characteristics, benefits, and precautions for using this promising ingredient.
What is Retinal?
Retinal, also known as retinaldehyde, Retinal is a derivative of vitamin A belonging to the retinoid family. Unlike retinol, which requires two conversion steps to become active, retinal requires only one.
Retinal vs. Retinol: What Are the Differences?
Efficiency and Speed of Action
When applied to the skin, the retinol undergoes initial oxidation to transform into retinal, before being converted into retinoic acid, biologically active form of vitamin A. As a result, retinal is often considered more powerful than retinol due to its more direct conversion to retinoic acid. This increased effectiveness allows for faster visible results, particularly in terms of reducing wrinkles and improving skin texture.
Skin Tolerance
Although retinal is more powerful, it is generally well tolerated by the skin. However, due to its potency, it can cause irritation, especially on sensitive skin. It is therefore recommended to gradually introduce retinal into your skincare routine, starting with a low concentration of between 0.015% and 0.1%.
Benefits of Retinal for the Skin
Anti-Aging Action
Retinal stimulates collagen production, which helps reduce the appearance of wrinkles and fine lines. It also improves skin elasticity, making it firmer and more toned.
Improvement in Skin Texture
By promoting cell renewal, retinal helps refine skin texture, making it smoother and more even. It also helps reduce pigmentation spots, resulting in a more even complexion.
Acne Treatment
Thanks to its antibacterial properties, retinal is effective in treating acne by reducing inflammation and preventing the appearance of new blemishes.
What ingredients can be combined with retinal?
Choose gentle ingredients that are well tolerated by all skin types:
. vitamin C to enhance antioxidant action (use as part of your morning routine)
. azelaic acid to target imperfections
. niacinamide in case of pigment spots
. hyaluronic acid for optimal hydration
However, avoid combining it with AHA acids or BHA, which could cause skin irritation.
Precautions for use
Retinal should be used gradually to allow the skin to adapt to it. It is advisable to start with one or two applications per week, then increase the frequency depending on skin tolerance. In addition, as retinal is photosensitizing, it is best to apply it in the evening and use SPF 50 sunscreen during the day to protect the skin from UV rays.
