Boost Your Sunscreen's Effectiveness

Summer is here, and it's time to relax and make the most of this beautiful season. Now more than ever, it's crucial to use the right skincare products. Choosing can be challenging given the growing number of options available. Here are some tips to help you make the best choices to protect your youthful skin:

Did you know that you can enhance your sunscreen's effectiveness by applying a Vitamin C serum beforehand? Research shows that using pure L-ascorbic acid as a base layer under sunscreen helps combat more free radicals caused by the sun—the main source of skin aging—significantly slowing down the aging process.

Vitamin C and Photoaging

Photoaging refers to the premature aging of the skin due to repeated exposure to the sun's ultraviolet (UV) rays or artificial UV sources. "Photo" comes from the Greek word "phos," which means "light," indicating skin aging caused by light. Photoaging differs from chronological aging as the damaging effects of UV rays alter the skin's normal structures.

Photoaging can begin as early as in the twenties, especially in people with very fair skin or those who have overexposed themselves to the sun and tanning booths, and it is more evident in smokers. In cases of mild photoaging, the skin becomes less supple and radiant. As it progresses, there's uneven skin tone, darkening in some areas, a yellowish or rougher texture in others, lack of firmness, permanently dilated small blood vessels, particularly on the cheeks, chin, nose wings, and the appearance of fine lines outside of normal expression lines. These signs of photoaging will inevitably progress, leading to deeper wrinkles, dark spots, rosacea, a grayish complexion, and often precancerous skin lesions.

Today, numerous clinical studies significantly demonstrate the improvement in the appearance of photo-induced aging signs through the topical application of Vitamin C. Its reputation as a cosmeceutical ingredient is well-established.

What Makes Vitamin C Unique?

Vitamin C is the most crucial antioxidant for the skin, offering multiple benefits:

• Protects the skin from premature aging, including that caused by sun exposure;
• Regulates pigmentation, thereby preventing the appearance or intensification of dark spots;
• Facilitates collagen formation, enhancing skin firmness;
• Reduces water loss, thus improving hydration.

Wrinkles and fine lines are significantly reduced, skin texture is smoothed, and skin regains tone and firmness, reactivating the radiance of the complexion.

Vitamin C has definitely established itself as a major active ingredient in combating premature aging.

Unique Features of the 10% Vitamin C Serum with M2PE by Laboratoire Dr Renaud

The 10% Vitamin C Serum with M2PE contains the purest and most bioavailable form: L-ascorbic acid. However, L-ascorbic acid is extremely sensitive to air, light, and water when used directly in a skincare product: it oxidizes very quickly, losing effectiveness and becoming irritating.

Laboratoire Dr Renaud has perfected a delivery system that provides greater stability for ascorbic acid compared to other vitamin C products, allowing for better penetration into all skin layers, thus offering maximum antioxidant protection. The 10% Vitamin C Serum with M2PE is stable, absorbed by the skin, and remains effective for up to 24 hours. Its rapid absorption enhances its effectiveness.

Here is a very simple daily program, designed for summer, based on the effectiveness of the 10% Vitamin C Serum with M2PE by Laboratoire Dr Renaud:
