Day Cream, Night Cream: What’s the Difference?
Collagen, Essential for Youthful-Looking Skin
Collagen, produced by fibroblasts, is a fibrous protein naturally present in the skin. It is also the main component of connective tissue and gives it its elasticity, suppleness, and strength.
From the age of 20, the body stops producing collagen, and the slow progression of skin aging begins. With a loss of 1% of collagen per year, the first signs of aging inevitably appear around the age of 30: fine lines, loss of firmness and elasticity.
To limit the impact of this loss of collagen, which causes wrinkles and sagging skin, it is essential to use anti-aging skincare from a young age, ideally from 20-25. We then have 2 options:
- Either provide the skin with collagen, generally of marine origin (derived from algae) or animal origin (from fish and shellfish), through a cosmetic skincare product. In this case, collagen helps protect, hydrate, and smooth the skin, but its effect remains very superficial and stops as soon as application is discontinued.
- Or restart the skin’s natural collagen production. By stimulating collagen synthesis, the skin itself regenerates deeply and naturally, producing truly long-lasting results.
Although the first solution may seem the easiest to implement (many skincare products now include collagen in their formulas), its results are temporary and, above all, much less significant than when collagen renews naturally.

+ 43% increase in collagen synthesis thanks to an exclusive patented active ingredient: ISAGÈNE!
By stimulating collagen synthesis, the Graine de Pastel Regenerating Anti-Aging Night Cream helps redensify the skin, correct visible signs of aging, and prevent the appearance of new ones, such as wrinkles and fine lines, sagging, and loss of radiance.
Its secret? ISAGÈNE, an exclusive patented active ingredient discovered and fully developed by the Graine de Pastel laboratory after more than 5 years of research into the raw material. A true innovation derived from woad proteins, ISAGÈNE is one of the few active ingredients capable of acting at the heart of dermal cells by restarting the natural production of collagen and blocking the degradation of its fibers. It therefore increases collagen synthesis by 43%!
More numerous, collagen fibers restore the skin’s elasticity and act deeply to combat the appearance of wrinkles, reduce existing wrinkles, redefine facial contours, and restore smoother, firmer, plumper-looking skin.
For its protective and antioxidant action, the Regenerating Anti-Aging Night Cream also contains woad oil, exceptionally rich in omega 3, 6, and 9, as well as vitamin E, which contributes to the skin barrier effect.
Night after night, the skin is revitalized and appears denser and visibly younger!
Suitable for all skin types, the rich texture of the Regenerating Anti-Aging Night Cream melts into the epidermis for rapid absorption and nourishment throughout the night. Combined with the Firming Serum and Redensifying Day Cream, it promises genuine anti-aging effectiveness:
- 82% of users noticed firmer-looking skin*
- 82% of users noticed smoother-looking skin*
- 76% of users noticed plumper-looking skin*
Formulated with 99% naturally derived ingredients and certified organic by Ecocert, the Graine de Pastel Regenerating Anti-Aging Night Cream draws on the best of an ancestral medicinal plant, woad, through its major innovation ISAGÈNE, to offer organic, patented anti-aging skincare with proven results.
