Agelyss Age Defying Day Serum Review

Manufacturer’s Claim

The following review is for a product called Agelyss Age Defying Day Serum. The manufacturer claims that this product contains patented active, trademarked and clinically-proven ingredients which penetrate deeply into the skin in order to firm and tighten skin. They further claim that this product will reduce fine lines and wrinkles, promote cellular repair, regulate oil production, soothe irritation, improve and restore elasticity, slow down the aging process and boost collagen production. It is also said that this formula will aid skin renewal, preserve the function of the human skin stem cells, reduce photo-aging, protect your skin from external elements, improve facial contours and boost skin immunity.

In this review, we list the facts to see if the manufacturer lives up to its claims about the product. Also, find out what to look for when reading day serum reviews.


  • Pepha-Tight
  • Gatuline Expression
  • Argireline NP
  • Trylagen PCB
  • PhytoCellTec Alp Rose

Pepha-Tight is an extract that is derived from microalgae, it increases the formation of collagen and instantly tightens skin in order to offer long-term skin-firming benefits. Gatuline Expression is also known as a natural botox as it targets cell communication and immediately improves deep wrinkles, smile lines and eye contours. Argireline NP reduces facial wrinkles and regular use has even shown effectiveness against their development. Trylagen PCB is a combination of proteins and peptides that smooth out fine lines, plump out wrinkles, prevent collagen degradation, boost collagen production and combat aging skin. PhytoCellTec Alp Rose has been proven to aid skin cell renewal and preserve the function of human skin stem cells. (Read more about the human skin stem cells and the aging process).

The ingredients mentioned above are the active patented ingredients included in this formula. When reading other day serum reviews, you’ll find that most day serums include only one or two active ingredients. It is, therefore, quite impressive that this formula contains 5 active and clinically proven ingredients. Even though one active ingredient may offer many benefits for a specific issue, it usually is not enough for a total care solution. There is no other product that comes close to the effectiveness of this formula because of the wide range of researched, active and quality ingredients contained in this formula.

Because of the fact that this formula contains 10% active, quality active ingredients it is said that it will penetrate deep into both the epidermis and dermis to repair damaged skin and boost moisture. It also offers protection from free radical damage and other external elements in order to prevent future damage and to maintain top skin health.

It is lastly also a product which is very safe to use as it complies with the US Pharmacopeia’s standards for purity and quality and it has been third-party tested to ensure effectiveness and safety. We also like the fact that it has not been tested on animals and that it is suitable for vegans. It has been registered in an FDA registered laboratory and is also cGMP certified.


The serum should be massaged directly onto the neck and face. It should be applied daily and under a moisturizer, throughout the day, for best results. It is suitable for a wide variety of skin types.


One day serum can be bought for $69.00. The three-pack-deal can be bought for $43.00 each and the six-pack savings package can be purchased for $33.00 each. The company is offering incredible discounts, as you will save $139.00 if you opt for the three-pack deal and $336.00 if you buy the six-pack savings package.

Possible Side Effects

This product is formulated without hormones, parabens, animal by-products, petrochemicals, synthetic dyes or phthalates. It also does not contain synthetic fragrances as they use 100% natural pure distilled essential oils. This makes it an extremely safe product to use with little to no side effects.

The product is also suitable for all ages and skin types, including sun damaged, mature and sensitive skin. It is a really safe product to use as it has been clinically tested and formulated without any harsh ingredients, which often provoke various skin irritations and are also dangerous for the environment and for your health. When reading day serum reviews you’ll find that no side effects have been reported when using this product.

What makes this product even purer, is the fact that it comes in an airtight sealed container which ensures the integrity and freshness of the formula. It also comes with a protective seal which will avoid contamination and, in turn, influence results.


We find it really impressive that the manufacturer offers a 365-day money back guarantee. If you are not 100% satisfied with your purchase, for any reason, you can simply return all the purchased bottles for a full refund. You don’t have to worry if you order multiples and take advantage of the price discount, as any containers, both opened and unopened will be eligible for a return. This shows us that the manufacturer is really confident about the effectiveness of their products and they know that their products do show results. This excellent money-back guarantee gives the consumer a chance to try out the product without the risk of losing their money. If you don’t see results, you don’t pay. There are many day serum companies who do not offer a money-back guarantee at all or who offer a guarantee only for a few days or weeks. These types of guarantees don’t give the consumer enough time to really find out whether the product is working for them or not.

The fact that this product is also GMP certified, made in an FDA registered facility, complies with the US Pharmacopeia’s standards for purity and quality and the fact that it has been third-party tested to ensure effectiveness and safety also gives the client much more peace of mind when making the purchase.

Agelyss Age Defying Day Serum – The Bottom Line

We have found that Agelyss Age Defying Day Serum is definitely one of the best anti-aging day serums available on the market. It is based on extensive research and it concentrates on actual science and clinical data to ensure you get a quality product. There are many other manufacturers who put together inferior products by using only around 2% active ingredients. With 98% inactive ingredients, these products are watered down. A really effective and quality anti-aging day serum will contain at least 10% active ingredients.

If your end goal is to firm and tone your skin, maintain a youthful appearance and reduce wrinkles and fine lines, we would highly recommend you try out this formula. The fact that the manufacturer offers a 365-day money-back guarantee also shows us that they are really confident about the effectiveness of their products. This also gives the consumer a chance to try out the products risk-free.

The fact that this product is formulated without hormones, animal by-products, parabens, synthetic dyes, phthalates or petrochemicals also makes it an extremely safe product to use. They make use of only natural distilled essential oils and no synthetic fragrances and the chance is, therefore, good that you won’t be experiencing any negative side effects. It is also suitable to all skin types and ages, including mature, sensitive and sun-damaged skin. As it contains no toxic substances, it won’t provoke skin irritations and it also isn’t dangerous for your health or for the environment.

Stick to the following guidelines when buying a new anti-aging day serum to ensure you get the highest quality product:

  • Make sure that it contains 10% or more active, trademarked, clinically-proven ingredients.
  • Make sure that it contains 5 or more active, trademarked, patented and clinically proven ingredients (5 or more active ingredients are necessary in order to work on a specific issue and area, while products with less than 5 clinically proven ingredients will be less effective and you will, therefore, require more than one product in order to address the same issue).
  • Avoid products that have not been researched. A quality product will be backed by research as it will show the client what results can be expected. This information should also be freely accessible.
  • Avoid weak, dangerous and unhelpful blends – make sure that there aren’t any added ingredients which might alter the results. Avoid products which contain phthalates, hormones, parabens and synthetic fragrances as they may cause dryness and do damage to the skin long-term.
  • Avoid free trial offers and automatic rebilling as many companies offer a free trial to lure you in and once you buy, it’s difficult to cancel as they often automatically bill your credit card each month. Make sure to acknowledge what you are paying for and to read the fine print.
  • Avoid products that have been tested on animals – many companies have boycotted testing their products on animals as there is no need to do this in today’s scientifically advanced world. It really is not necessary to torture or abuse animals in order to test the effectiveness of ingredients – there are many other ways to do this.
  • Be on the lookout for unsupported facts and false claims – make sure that any company you buy from supports their claims with research.
  • The day serum should be hygienically sealed and come in a sealed airtight container to optimize effectiveness by ensuring the freshness and stability of the ingredients.
