Anti-aging products
Cosmetic products are intended to give the skin the appearance of being clearer, to remove wrinkles, or to increase the skin’s collagen[clarification needed]. The skin is the body's largest surface and interacts with the external environment. Cosmetic products are used to allow the skin to appear clearer, less textured, and brighter. They protect the skin barrier or change its appearance through ingredients like collagen and peptides, providing different effects based on the goal. Anti-aging products are designed to slow the progression and appearance of those changes.
Background
The first steps in skincare date back to the women of Ancient Rome and Ancient Greece: face masks were made with rosewater, animal fat, arugula, cucumber, almond oil, and eggs. Early medicinal efforts required innovation. The Ancient Egyptians were in the world of beauty, very fond of cleansing, and massaged ointments into the skin daily to keep it from drying out. Over time, ladies used Blanchet to lighten their complexion in pursuit of a pale look and cleansed with sour milk.[citation needed]
In the early 20th century, there was an increase in popularity for skin care, moisturizers, soaps, and night masks. Herbal and natural remedies became more desirable in the last half of the century; due to the outbreak of war, there was a low stock of skincare products. On a smaller scale, over the past 50 years, products have changed. The goals or ideals of that time period influenced the type of skin care products to be used. In the 1970s, during the feminist wave and the hippie era. Women had begun to reject the appearance of unnatural and cosmetic looks. During the 1980s, however, excessive makeup and a full-coverage appearance became popular. Anti-aging creams entered the stores; skincare was taken towards a medical approach. However, as the 2020s approach, skincare products had become more desirable for sustainable, personalized. Apps were created to track progress, and ingredients. The look of glowing, healthy with fewer products became the goal.[1]
Collagen
For skin elasticity or stretchiness, collagen makes up three quarters of the skin. Collagen helps maintain the fine lines that appear over time. Smoothing out wrinkles to helps improve and preserve the skin. Skin care supports the skin’s process by creating an environment for skin cells to grow. Cells regenerate, which improves dullness and uneven skin tone. Nonetheless, rashes, acne breakouts, and skin inflammation can occur, creating roughness. Combining amino acids, building blocks of proteins found in food, to produce collagen. [2]
Proline
The amino acid that helps retain moisture, supports hydration, and acts as a barrier. As a result, it is linked to a smoother appearance and reduced dryness. Proline is commonly found in hydrating serums and in face creams that are moisture focused. Due to the gentleness of proline, there is low irritation for sensitive skin. As of 2026, from Skincare Lab, “No known photosensitizing or comedogenic concerns at cosmetic use levels.”[3]
Glycine
Glycine is the smallest amino acid in the body but plays various roles in aging. Glycine being a component of collagen, may improve skin health and wrinkles. As aging continues, the levels of glycine being produced lowers. Providing the body with the glycine will give the skin the appearance of clearer and help with wrinkles. [4] Glycine is a contributing factor in slowing down, even though it is minuscule.[5]
Vitamin C also known as ascorbic acid comes in forms of serums and creams allowing the skin to absorb. Skin is under the constant exposure to the outside sun UVs, pesticides, and air contaminants. However, antioxidants can protect the skin from the free radicals. A study showed that vitamin C helped improve the dark under eye circles. The circles are caused by pooled blood, thinking the skin under the eye makes for pooled blood more difficult to see.[6] The study showed that Vitamin C's collagen boosting helped improve the appearance of the dark circles. [7]
Skin Regeneration
Collagen is an anti-aging agent that enhances the skin’s elasticity, ability to hold onto moisture, and ability to heal. Collagen peptides are defined as tiny pieces of animal collagen and are absorbed through the gastrointestinal tract. With research, there is affirmation that consistency plays a role in the results.
Peptides
A peptide is described as a short chain of amino acids, typically acting as messengers to perform functions. Peptides are backed scientifically as a multifunctional ingredient in skincare, with targeted benefits ranging from collagen stimulation to anti-inflammatory and brightening effects. They carry a low risk of irritation, making them suitable for daily use and useful for all age groups and skin types. With that, there is a selection of peptides combined with a well-rounded skincare routine. Allowing the balance to improve skin tone, texture, and resilience over time. In skincare, peptides are meant to mimic that natural look and encourage specific responses in the skin. Signaling peptides, carrier peptides, enzyme-inhibitor peptides. Signaling peptides are to encourage the collagen production, as well as elastin production. Improves the firmness and elasticity. Carrier peptides are to deliver minerals like copper for skin. Enzyme-inhibitor are involved with the collagen breakdown, meant to help persevere the existing collagen. Depending on the goal of applying skincare, it determines the type of product necessary. [8]
