What is retinal and why is it so effective?
Retinal (retinaldehyde) is an active form of vitamin A that stimulates cell renewal, supports collagen synthesis, and improves skin texture and evenness – a key ingredient in anti-aging skincare.
Retinal is considered one of the most effective ingredients in modern skincare for wrinkles and uneven skin tone, as it combines high activity with good tolerability when formulated correctly.
Why does retinal sometimes cause irritation?
When starting use, the skin goes through an adaptation process known as "retinization" (adaptation to retinal).
This can lead to:
• Dryness
• Mild flaking
• Increased sensitivity
These are common side effects when starting retinal and retinoids. In many cases, this is a natural response to accelerated cell renewal, rather than a sign of intolerance to the ingredient.
Does the formula matter?
Retinal is the same molecule, regardless of the source.
The difference in tolerability comes from how the product is formulated - a key factor when choosing a retinal product.
In simpler formulas, retinal can act more aggressively, increasing the likelihood of irritation for sensitive skin.
In well-balanced formulas that include lipids, nourishing oils, and modern delivery systems, the action is smoother and more comfortable for the skin.
This supports:
• Easier adaptation
• Better support for the skin barrier
• Lower risk of discomfort
How to start with retinal correctly?
The most common mistake is introducing retinal into the routine too quickly.
Recommended approach:
• Start 2–3 times a week
• Use a small amount
• Apply to completely dry skin
• Avoid the eye area initially
• Combine with a hydrating or restorative cream
This is the optimal retinal routine for beginners. Over time, the frequency can be increased according to individual tolerability.
How to build a retinal routine?
Evening:
• Gentle cleansing
• Retinal
• Moisturizing cream
Morning:
• Hydration
• Mandatory SPF (sun protection with retinal)
Retinal makes the skin more sensitive to UV rays, so daily protection is key.
What to avoid?
These are important rules for using retinal without irritation, to minimize the risk:
• Do not combine with acids initially
• Do not use excessive amounts
• Do not skip hydration
• Do not neglect SPF
Can retinal be used every day?
Over time and with good tolerability, retinal can be used more frequently in a daily evening routine.
With well-formulated products, this transition is usually smoother and more comfortable for the skin.
When to expect results?
Retinal requires consistency. These are visible results from retinal with regular use:
• 2–4 weeks → improved texture
• 6–8 weeks → more even skin tone and smoothing of fine lines
The Face Oil Elixir Youth Boost combines biotechnologically developed retinal with centella asiatica phytosomes and a selection of nourishing oils.
A formula designed to work in synergy with the skin – with a smoother action, good tolerability, and a focus on long-term balance.
