Description
Anti-aging day cream with broad-spectrum SPF 50 and peptides
A day cream with SPF 50 provides the highest level of daily UV protection for those facing more than just occasional sun exposure. For mature or dry skin with visible signs of aging, this level of protection is not a luxury but a necessity — UV radiation is responsible for up to 80% of visible skin aging. At the same time, this skin demands more than just a filter: peptides, antioxidants, and deep hydration are needed to address existing signs of aging alongside prevention.
Cosmedix Peptide Rich Defense combines these two functions in one concentrated day cream. The formula combines broad-spectrum SPF 50 with palmitoyl tetrapeptide-7 and palmitoyl oligopeptide — two peptides that actively target fine lines and wrinkles. Supplemented with trehalose, squalane, and vitamin E for deep hydration and antioxidant protection. With over 200 reviews, this product is among the bestsellers in the Cosmedix range, especially for mature users and those seeking a day cream that visibly works.

Active ingredients
Avobenzone 3.0%, Octinoxate 7.5%, Octisalate 5.0%, and Oxybenzone 5.0%: A combination of chemical UV filters that together provide broad-spectrum protection against both UVA (skin aging) and UVB (burning) rays. Avobenzone is especially valuable for its broad UVA spectrum, an area many classic sunscreens inadequately cover — while UVA is responsible for visible signs of aging.
Palmitoyl Tetrapeptide-7: A peptide with targeted action on skin structure. Research shows this peptide contributes to smoother-looking skin and reduces the visibility of fine lines. Works synergistically with palmitoyl oligopeptide for a complete peptide profile.
Palmitoyl Oligopeptide: A second targeted peptide that supports natural skin renewal. Helps reduce the visibility of wrinkles and contributes to firmer-looking skin with long-term use.
D-trehalose: A natural sugar known in science as a 'survival molecule.' Retains moisture in the skin under harsh conditions — dry air conditioning, cold wind, summer heat — without leaving a greasy film.
Squalane: A biomimetic lipid identical to a natural component of the skin's sebum. Strengthens the skin barrier and prevents moisture loss. An ingredient found in almost all premium Cosmedix moisturizers for its excellent tolerance.
Vitamin E (Tocopheryl Acetate and Tocopherol): A lipid-soluble antioxidant in two complementary forms. Protects against UVB damage, enhances the effectiveness of UV filters, and supports skin repair.
Moringa seed extract (Moringa Pterygosperma): An Asian ingredient rich in vitamins and antioxidants. Helps protect the skin from cumulative damage caused by urban pollution, fine dust, and blue light.
Saccharomyces Cerevisiae extract: A fermented yeast extract that supports the skin barrier and contributes to a healthy-looking complexion. An ingredient widely used in the fermented skincare movement for its strengthening properties.
Algae extract and Boerhavia Diffusa root extract: Two plant-based ingredients with antioxidant properties. Help calm the skin and contribute to an even complexion, even after intensive sun exposure.
Glucosamine HCl and allantoin: Two soothing ingredients that keep the skin supple and help reduce sensitivity. Allantoin is especially valuable for its effect on the skin barrier.
Safflower oleosomes (Carthamus Tinctorius): An innovative delivery system that releases active ingredients into the skin. Ensures even distribution and sustained action of peptides and antioxidants.

Frequently asked questions
What is the difference between Peptide Rich Defense and Hydrate+ SPF [1.7]?
Two different SPF levels for different needs. Hydrate+ SPF [1.7] is a daily hydrator with basic protection for office, commuting, and general use. Peptide Rich Defense SPF 50 provides the highest level of protection with added anti-aging peptides — suitable for those who spend more time outdoors, for mature skin, or for those actively addressing signs of aging. Both products should not be used simultaneously — you choose one depending on your daily need.
Does this product contain chemical UV filters? Is that safe?
Yes, Peptide Rich Defense uses chemical filters (avobenzone, octinoxate, octisalate, oxybenzone) instead of mineral ones like zinc oxide. Chemical filters are widely studied and approved by regulatory authorities worldwide for safe use on the skin. Those who prefer mineral filters can choose Hydrate+ (zinc oxide) or Zinc Defense (zinc oxide with a matte finish).
Can I use Peptide Rich Defense during pregnancy or breastfeeding?
The formula contains oxybenzone, a chemical UV filter that some professionals advise against during pregnancy and breastfeeding. For those seeking maximum safety during these periods, Hydrate+ SPF 17 or Zinc Defense SPF 30 — both with mineral zinc oxide — are safer choices. Always consult your midwife or skin therapist if in doubt.
Does Peptide Rich Defense work under makeup?
Yes, and that is one of the most appreciated features of this product. The cream has a dewy, non-greasy finish that works excellently as a base under foundation. No white cast, no greasy shine — just a hydrated, smooth base. Many makeup artists recommend Peptide Rich Defense as a base for mature skin for the best results under liquid foundation.
When will I see the first anti-aging results from Peptide Rich Defense?
The moisturizing effect is visible immediately after the first application. The direct smoothing effect of the peptides is noticeable within a few weeks. For structural reduction of fine lines and wrinkles, daily use for 8 to 12 weeks is recommended. Remember: without consistent SPF, no anti-aging routine works optimally — this product combines both.
How much Peptide Rich Defense do I need per application?
For effective UV protection according to international guidelines, about a quarter teaspoon is needed for the face and neck — a "quarter-sized amount" as recommended by Cosmedix. Underestimating the amount is a common reason why protection in practice is lower than stated on the tube. Be generous; it really makes a difference for the skin.
How long does a 50ml tube last?
With daily use, a tube typically lasts two to three months. If you reapply in the afternoon or use the product on the décolleté and hands, it lasts about one to one and a half months. Keep an extra tube or travel size on hand for reapplication outside — consistent use is the key for the best anti-aging results.
