What the product description says
“An oil-free salicylic acid face serum that reduces the formation of adult acne and improves visible signs of aging.”
Source: Skinceuticals

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

Glycolic acidKey activeEffect: HighAn 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~3.7–5.5%

What the product description says
“Improves the appearance of blotchiness, blemishes, and uneven skin tone.”
Source: Skinceuticals

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

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: capryloyl salicylic 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.

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: capryloyl salicylic acid, glycolic acid.

Product summary

"SkinCeuticals - Blemish + Age Defense Serum" is effective for: Anti-inflammatory, Exfoliation, Anti-aging, Evens skin tone and Anti-blemish

Ingredient callouts

  • Exfoliating acids (glycolic acid 3.70% - 5.50%). 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.
  • Salicylic acid (0.55% - 1.25%). This is an oil-soluble exfoliating acid. Because of this property, it can work inside pores and help reduce the congestion. It has an anti-inflammatory effect and is used to treat acne. Because it is a quite strong exfoliator, be careful with using this product too often: it could result in over-exfoliation.

Price

The product retails from 52.00£ up to 114.00£ in the United Kingdom, for 118.00CA$ in Canada and for 115.00$ in the United States.
