CUSKIN Clean-Up Retinol Activator 0.5% is a retinol serum built around the brand's oleosome delivery technology, designed to introduce retinol gradually so the formula stays comfortable to use — even for skin that doesn't usually get on well with actives.

Oleosomes are tiny natural spheres found in the seeds of oil-bearing plants. Here they act as a release system, letting the retinol settle into the skin slowly rather than all at once. That measured release is what keeps the experience smooth and helps make a 0.5% concentration approachable. CUSKIN pairs this with ferulic acid, so the serum can suit reactive and more sensitive skin types looking to start or build a retinol routine.

Key ingredients

  • Encapsulated retinol with 5000 ppm oleosome technology — helps visibly smooth the look of fine lines and uneven texture, supports a firmer, more even-looking complexion, and helps brighten the appearance of dull, uneven tone.
  • Ferulic acid — an antioxidant that supports the retinol and helps skin adapt to it more comfortably, while helping the complexion look more even.
  • Macadamia oil — moisturises, softens and nourishes, helping protect against dryness and flaky-looking skin.
  • Gluconolactone — a gentle PHA that hydrates and helps smooth the look of skin texture.
  • Boswellia and Japanese coptis root extracts — help soothe and comfort the skin and support a balanced, less shiny appearance.

Who is it for?

It suits anyone wanting to introduce retinol for a smoother, firmer-looking, more even complexion — including reactive and sensitive skin types thanks to the gradual oleosome release. Used by women and men alike.

How to use

Apply in the evening to clean, dry skin. Smooth a small amount over the face, avoiding the eye area and lips. Follow with a moisturiser. Because this is a retinol serum, start two to three nights a week and build up as your skin gets used to it. Always wear a broad-spectrum sunscreen during the day while using retinol.

How to use

After cleansing and toning, apply the serum (2-3 pumps) to dry skin on the face, neck and décolleté, distribute along the massage lines. After complete absorption, finish the treatment with a restorative cream. It is important to introduce retinol into your care very carefully, the amount of the product at the beginning should be minimal. During the first 2 weeks, use the cream 2 times a week. The next 2 weeks – every other evening. Then you can use it every night (if there is no irritation). Use only in evening care! In the morning, don't forget to protect your skin from the sun (SPF50+PA+++)
