What the product description says
“Formulated with Peptides to strengthen the skin barrier and improve skin firmness, as well as Ceramides to strengthen the skin’s moisture barrier to prevent moisture loss,”
Source: Lila Beauty

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: betaine, glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, cholesterol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide ap, ceramide as, ceramide eop, ceramide np, ceramide ns, copper tripeptide-1, niacinamide, palmitoyl pentapeptide-4, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, panthenol, phytosphingosine

NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture.

“Isntree Hyper Retinol EX 1.0 Serum is an anti-aging serum that contains 1% Retinol EX to reduce the appearance of fine lines and wrinkles.”
Source: Lila Beauty

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinol, adenosine, bakuchiol, niacinamide.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, asiaticoside, copper tripeptide-1, ferulic acid, palmitoyl pentapeptide-4, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

RetinolHeroEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid.

The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritation0.6%

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinol.

In addition, this product contains bakuchiol, niacinamide. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Evens skin toneAnti-blemishAnti-agingExfoliation

Three steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect

A naturally occurring peptide. One of the most studied peptides in dermatology. It is sometimes abbreviated GHK-Cu. Belongs to the class of carrier peptides. It stimulates both synthesis and breakdown of collagen in skin. It is released in skin wounds and inflammation to support healing. It accelerates wound-healing of the skin and can stimulate hair growth. There are preliminary studies that confirm that copper tripeptide can help support collagen production reducing fine lines and wrinkles and decrease inflammation in skin.

Ingredient callouts

  • A good concentration of Niacinamide (3.10% - 3.70%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
  • This product contains an effective form of Retinoids (vitamin A): retinol 0.10% (declared). Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
  • Ceramides (ceramide eop 0.10% - 0.20%, ceramide ap 0.20% - 0.35%, ceramide as 0.20% - 0.40%, phytosphingosine 0.25% - 0.50%, ceramide ns 0.25% - 0.50% and ceramide np 0.25% - 0.50%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
  • Peptides (palmitoyl tripeptide-1 0.15% - 0.25%, palmitoyl tetrapeptide-7 0.15% - 0.30%, palmitoyl pentapeptide-4 0.15% - 0.25%, acetyl hexapeptide-8 0.15% - 0.30% and copper tripeptide-1 0.15% - 0.30%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that theynare helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
  • Adenosine 0.35% - 0.65%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
  • Actives derived from an extract of the Centella Asiatica plant (also known as Gotu Kola) - asiatic acid 0.20% - 0.40%, madecassic acid 0.25% - 0.45% and asiaticoside 0.20% - 0.35% The Centella Asiatica Actives help strengthen and restore the skin barrier, decrease inflammation in skin and neutralize free radicals. They also can help to reduce scarring. The good news is that these actives work even in low concentrations.
  • Humectants (acetyl hexapeptide-8 0.15% - 0.30%, betaine 0.70% - 1.05% and glycerin 4.10% - 5.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
