Glycolic acid, Gluconolactone + 2 more
Not delivered

This product contains ingredients (gluconolactone, glycolic acid, zinc pca) that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.

Glycolic acidKey activeEffect: MediumAn alpha-hydroxy acid (AHA) that helps to remove the dead skin cells on the surface of the skin reveling a more even, smoother complexation. It is also able to stimulate collagen production with long-term use. Could help to reduce pore congestion. It can be irritating to the skin. Apply sunscreen daily if using products with glycolic acid~5.9–7.2%
GluconolactoneKey activeEffect: MediumA polyhydroxy acid (PHA) that helps shed the dead cells from the skin surface revealing smoother skin. Is believed to be genter than AHAs. It helps attract water to the upper layer of the skin and can stimulate production of skin's own hyaluronic acid resulting in improved hydration levels. It has been shown to be helpful against acne and clogged pores if used consistently (e.g over a period of 12 weeks) in high enough concentration. It can help reduce fine lines and wrinkles and improve skin tone with long-term application. Can help neutralize free radicals~4.1–5%
Zinc pcaKey activeEffect: MediumA compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing~0.55–0.8%
Salicylic acidUnder-dosedUsed for skin exfoliation. It has an anti-inflammatory and anti-bacterial effect, helps to unclog pores, prevent blemishes and speed up healing of the existing ones. Sometimes referred to as a BHA (beta-hydroxy acid)~0.4–0.6%
Exfoliation
Not advertised by the brand · Glycolic acid, Gluconolactone + 1 more
Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: gluconolactone, glycolic acid.

Evens skin tone
Not advertised by the brand · Glycolic acid, Gluconolactone + 1 more
Works well

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: gluconolactone, glycolic acid

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.

Anti-aging
Not advertised by the brand · Glycolic acid, Gluconolactone + 2 more
Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains gluconolactone, glycolic acid.

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.

This product contains antioxidants (gluconolactone) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.

Moisturizing
Not advertised by the brand · Gluconolactone, Xylitylglucoside + 6 more
Works

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": anhydroxylitol, xylitylglucoside.

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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

Product summary

"Isispharma - Teen Derm K concentrate" is effective for: Exfoliation, Evens skin tone and Anti-aging

This product could be helpful for: Moisturizing, but its actives are not the most effective or are not well-studied.

Ingredient callouts

  • Exfoliating acids (glycolic acid 5.90% - 7.20%). In this concentration, they will have a noticeable exfoliating effect. They can also have an anti-aging effect and stimulate collagen production in a long-run. PHAs (gluconolactone 4.10% - 5.00%) in this product also work for improving skin hydration. They might be even able to stimulate the production of skin's natural humectants and support the healthy skin microbiome.
  • Humectants (anhydroxylitol 0.45% - 0.70%, zinc pca 0.55% - 0.80% and xylitylglucoside 0.65% - 0.95%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
