What is a retinol serum good for?

Retinol B3 Serum is designed to address a variety of anti-aging concerns including fine lines, deep wrinkles and premature sun damage. This face and neck serum leaves skin feeling smoother, hydrated, and renewed.

When should retinol be applied?

Retinol should be applied at night after cleansing the skin and before moisturizing. This is because retinol can make the skin more sensitive to sunlight, and applying it in the evening allows it to work effectively while you sleep. Here is a simple nighttime routine to integrate Retinol B3 Serum : Step 1: Cleanse – Begin by washing your face with a hydrating cleanser, such as Toleriane Hydrating Cleanser, to remove dirt, makeup, and impurities. Step 2: Treat – Apply Retinol B3 Serum evenly to clean, dry skin. Step 3: Moisturize – Follow with a lightweight moisturizer like Toleriane Double Repair Moisturizer to hydrate and protect the skin barrier.

How should retinol be introduced into my skincare routine?

To avoid irritation, it's recommended to introduce retinol gradually into your skincare routine. Start by applying it 2-3 times a week and then gradually increase the frequency as your skin builds tolerance. You can eventually use it every other night or every night, depending on how your skin reacts.

What signs of sensitivity can occur when starting retinol?

When first using retinol, some people may experience dryness, redness, flakiness, or a tight feeling. These are common signs of initial sensitivity. If these symptoms persist, you can reduce the frequency of application or pair it with a soothing moisturizer to calm the skin.

Which products should be avoided when starting to use a retinol serum?

Retinol can be quite potent, so it’s best to avoid using it with other exfoliating products such as AHAs or BHAs in the same routine, as they can increase irritation. Additionally, avoid layering retinol with products containing benzoyl peroxide or other acne treatments that may be too harsh when combined with retinol.

Why is daily sunscreen recommended while using retinol?

Retinol can make your skin more sensitive to the sun, increasing the risk of sunburn and irritation. Therefore, it is crucial to apply daily sunscreen with a high SPF to protect the skin from harmful UV rays such as Anthelios UV Air Serum Sunscreen SPF 50. This helps prevent further skin damage and supports the skin's overall health and appearance while using retinol.

KEY INGREDIENTS:

Pure Retinol: A derivative of vitamin A (retinoic acid) that is widely recommended by dermatologists. When used in our formulas, it helps promote surface cell turnover and improves the appearance of fine lines and wrinkles.
Niacinamide: A form of vitamin B3, niacinamide is a water soluble vitamin. It is widely used in dermatology for its soothing properties, helping restore skin's moisture barrier, and visibly fading skin discolorations.
Hyaluronic Acid (HA): A polysaccharide (carbohydrate polymer) found naturally within the skin. When used in a formula, HA is an effective humectant that can hold a large amount of water to help maintain the skin's moisture.
Glycerin: Derived from vegetable sources, it's an excellent humectant. It helps hydrate skin by absorbing water from the surrounding environment.
Dimethicone: A silicone-based polymer used as a skin protectant to help reduce water loss.
La Roche-Posay Thermal Spring Water: A soothing water sourced in the town of La Roche-Posay in France and a core ingredient in most of our products. It contains a unique combination of minerals, trace elements, and a high concentration of selenium, a natural antioxidant.
