In the ever-evolving world of skincare, finding the perfect serum to address the signs of aging can be a daunting task. However, the Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum has emerged as a promising contender in the market. This serum claims to target wrinkles and fine lines, providing a youthful and radiant complexion. In this review,we will delve into the scientific aspects of this serum, including its key ingredients, texture, return policy, and consumer reviews.

What are our top skincare picks?

Who is it for?

The Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum is designed for individuals who are concerned about the appearance of wrinkles and fine lines on their skin. It is suitable for all skin types, including dry, oily, combination, and sensitive skin. This serum is particularly beneficial for those who wish to combat the signs of aging and improve the overall texture and tone of their skin.

What are the key ingredients?

The effectiveness of any skincare product lies in its formulation, and the Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum boasts a powerful blend of ingredients. Let’s take a closer look at some of the key components:

Peptides: Peptides are short chains of amino acids that play a crucial role in stimulating collagen production. Collagen is a protein responsible for maintaining the skin’s elasticity and firmness. By incorporating peptides into the formula, this serum aims to promote collagen synthesis, thereby reducing the appearance of wrinkles and fine lines.

Neuropeptides: Neuropeptides are specialized peptides that target specific receptors in the skin, helping to relax facial muscles and minimize the formation of expression lines. By including neuropeptides in its formulation, this serum aims to smooth out existing wrinkles and prevent the formation of new ones.

Hyaluronic Acid: Hyaluronic acid is a naturally occurring substance in the skin that helps to retain moisture, resulting in a plump and hydrated complexion. By incorporating hyaluronic acid into the serum, it aims to improve skin hydration, reducing the appearance of fine lines and promoting a more youthful appearance.

Collagen: This serum contains collagen, a protein that provides structure and support to the skin. By replenishing the skin’s collagen levels, it aims to improve skin elasticity and firmness, reducing the appearance of wrinkles.

What are the best anti aging skincare ingredients?

Vitamin C

We’ve been hearing for years that Vitamin C is the best anti-aging ingredient. Vitamin C is a potent antioxidant that protects the skin from free radicals, the unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin.

Vitamin C also helps fade dark spots, evens out skin tone, and increases radiance. As if that wasn’t enough, research suggests that when vitamin C is applied to the skin, it significantly reverses aging-related structural changes by influencing collagen and elastin synthesis.

But our favorite Vitamin C serum is Carrot & Stick The Defence Serum. It contains 3 distinct types of Vitamin C that work together to help fight free radical damage. We recommend using it every morning.


As you age, your body’s production of collagen and elastin slows down. These two proteins are responsible for your skin’s structural support. As a result, the skin loses its natural plumpness and smoothness.

While collagen is necessary for maintaining youthful-looking skin, the collagen protein is too large to absorb into the skin topically. That’s why applying skin care products that contain collagen won’t provide the anti-aging benefits you’re looking for.

This is where peptides come into action. Peptides are the building blocks of protein, and they are easily absorbed into the deeper layers of skin due to their smaller size.

If you’re looking for a peptide serum, recommend Carrot & Stick The Repair Serum. It contains 7 plant-based peptides to promote plumper and smoother-looking skin. It also has skin-loving ingredients like hyaluronic acid and niacinamide.


Retinol is the go-to anti-aging ingredient recommended by dermatologists and skin experts. Retinol is clinically proven to minimize the appearance of fine lines and wrinkles, improve uneven skin tone, restore skin firmness, and shrink the appearance of enlarged pores.

The only downside? Retinol can often lead to side effects like skin dryness, peeling, and irritation. Look for products that contain Hydroxypinacolone Retinoate, an ingredient that provides the same benefits of retinol but without the irritation. One that we recommend is this retinoid oil serum.

What is the texture like?

The Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum has a lightweight and silky texture, making it easy to apply and absorb into the skin. It does not leave a greasy or sticky residue, allowing for seamless integration into your skincare routine. The serum glides smoothly over the skin, leaving it feeling soft, smooth, and hydrated.

What is the return policy?

Peter Thomas Roth offers a 30-day return policy for products purchased directly from their official website. If you are unsatisfied with the Peptide 21 Wrinkle Resistant Serum, you can return it within 30 days of purchase for a full refund. However, it is essential to review the specific terms and conditions of the return policy before making a purchase.


Consumer reviews provide valuable insights into the efficacy of skincare products. Users have reported positive experiences with the Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum. They have noticed a visible reduction in the appearance of wrinkles and fine lines, as well as improved skin texture and hydration. Users appreciate the lightweight texture of the serum and its ability to absorb quickly into the skin without leaving any residue.

Users have also reported a noticeable improvement in the overall radiance and brightness of their complexion after incorporating this serum into their skincare routine. However, it is important to note that individual results may vary, and it may take some time to see significant changes in the skin’s appearance.

In conclusion, the Peter Thomas Roth Peptide 21 Wrinkle Resistant Serum offers a scientifically formulated solution for those seeking to combat the signs of aging. With its powerful blend of peptides, neuropeptides, hyaluronic acid, and collagen, this serum aims to reduce the appearance of wrinkles and fine lines while improving skin texture and hydration.
