What the product description says

“DESCRIPTION KSecret Collagen Boosting Secret Sun Lotion 60ml is a sunscreen that protects from sun exposure and offers anti-aging care.”

Source: Lila Beauty

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

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

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.

NiacinamideKey activeEffect: 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. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~1–1.5%

AdenosineKey activeEffect: HighMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.35–0.85%

Palmitoyl pentapeptide-4Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.3%

Acetyl hexapeptide-8Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.45%

Oligopeptide-1Key activeEffect: MediumA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.1–0.3%

Copper tripeptide-1Key activeEffect: MediumA 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.~0.1–0.4%

Hyaluronic acidEffect: LowOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin. Naturally present in skin. Typically has large molecule size unless advertised otherwise on the product label. Helps support skin's barrier function and may help to reduce inflammation~0.35–0.8%

Ascorbyl glucosideUnder-dosedA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products~0.15–0.55%

Moisturizing

Works well

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: glycerin, hyaluronic acid.

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: hydrolyzed collagen, c12-15 alkyl benzoate.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, copper tripeptide-1, niacinamide, oligopeptide-1, palmitoyl pentapeptide-4

"K-SECRET - Buy Collagen Boosting Secret Sun Lotion in Australia - Korean Skincare Online" is effective for: Anti-aging, Moisturizing, Evens skin tone and Anti-blemish

Ingredient callouts

Peptides (oligopeptide-1 0.10% - 0.30%, palmitoyl pentapeptide-4 0.10% - 0.30%, copper tripeptide-1 0.10% - 0.40% and acetyl hexapeptide-8 0.10% - 0.45%). 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% - 0.85%. 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).
Humectants (acetyl hexapeptide-8 0.10% - 0.45%, soluble collagen 0.20% - 0.80%, glycerin 0.20% - 0.75%, hydrolyzed glycosaminoglycans 0.15% - 0.65%, sodium acetylated hyaluronate 0.15% - 0.65%, sodium hyaluronate 0.35% - 0.75%, sodium hyaluronate crosspolymer 0.35% - 0.75%, hyaluronic acid 0.35% - 0.80%, hydrolyzed hyaluronic acid 0.35% - 0.80% and hydrolyzed collagen 22.00% - 33.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
