Retinol 2.5% Facial Serum

Retinol is a form of vitamin A and one of the most extensively studied active ingredients in cosmetic science. In this serum, it is combined with vitamin C, vitamin E, hyaluronic acid and collagen.

The role of retinol and vitamins in cosmetics

Retinol is used in cosmetics in formulations designed to improve skin texture and refine the complexion. Vitamins C and E are well-known antioxidants in the cosmetics industry, whilst hyaluronic acid helps to hydrate the formula and collagen is a commonly used cosmetic ingredient. Together, they form a concentrated, versatile formula.

This information describes the cosmetic context of the ingredients and does not constitute a medical claim.

A serum differs from a standalone research peptide in that the active ingredients are already incorporated into a balanced, ready-to-use carrier. With retinol, this formulation is particularly important, as retinol is a powerful yet sensitive ingredient that benefits from a carefully designed carrier and packaging. This attention to formulation makes the difference between a pleasant product and one that causes irritation.

Retinol and antioxidants such as vitamins C and E are among the most extensively researched ingredients in cosmetic science, particularly in formulations designed to address skin texture and ageing from a cosmetic perspective.

Cosmetic context

This serum is a cosmetic product; the areas of focus mentioned relate to cosmetic research and formulation, not to any medical effects. No claims are made regarding the treatment or cure of skin conditions. For a related antioxidant used as a research compound, see Glutathione.

Retinol is one of the most extensively researched active ingredients in cosmetics and is often combined with antioxidants and moisturising ingredients to create a balanced formula. For the user, this means a product that is ready to use; however, it is advisable to build up usage gradually, as retinol can make the skin more sensitive. Gradual build-up is therefore a common piece of advice for retinol products.

Retinol 2.5% Facial Serum is ready to use and is applied externally to the face. As retinol can make the skin more sensitive to sunlight, it is usually used in the evening.

1. 1Cleanse your face and pat your skin dry.
2. 2Apply a few drops of serum in the evening, avoiding the area immediately around the eyes.
3. 3Gently massage the serum in with your fingertips and leave it to absorb.
4. 4Use sun cream during the day, as retinol can increase your sensitivity to sunlight.
5. 5Build up your use gradually to allow your skin to get used to it.

Practical tips

Use the serum consistently in accordance with the instructions on the packaging. If you have sensitive skin, carry out a patch test on a small area of skin beforehand and discontinue use if irritation occurs. This product is for external cosmetic use only; do not swallow and keep out of the reach of children.

It’s best to start by using it a few times a week and gradually increase this as your skin gets used to the serum. Listen to your skin and adjust the frequency if necessary.

Store the serum in a cool, dry place, away from direct sunlight, to preserve the quality of the formula.

Practical storage tips

• Store at room temperature or in the fridge, away from direct sunlight.
• Keep the bottle tightly closed after use.
• Avoid extreme heat and freezing temperatures.
• Please check the use-by date on the packaging.

Storing the product in a cool, dry and dark place keeps the cosmetic formula stable and pleasant to use.

Retinol products should ideally be stored in a cool, dark place, as retinol is sensitive to light and heat.
