Westman Atelier’s Skin Activator is a hyper-potent, all-in-one serum formulated with 12 active ingredients including four types of hyaluronic acid, peptides, niacinamide, and prickly pear cactus extract. This serum is designed to restore, correct, and protect your skin by:
  • Softening fine lines

  • Improve skin texture and smoothness
  • Minimize pores and pigmentation

Its gentle, fragrance-free formula is suitable for all skin types, including sensitive skin, making it ideal for consistent daily use to maintain youthful, healthy-looking skin.

Night Repair Treatment: Potent Nighttime Renewal

Application Frequency:

  • How: Apply one pump to face, neck, and chest after cleansing; follow with moisturizer

Why Use It Nightly?

This serum combines bio-retinol (bakuchiol) and alpha hydroxy acids (glycolic acid and gluconolactone) to stimulate skin renewal and reverse signs of aging while you sleep. It is alcohol-free, fragrance-free, vegan, and suitable for sensitive skin. Regular nightly use helps:
  • Brighten and even skin tone
  • Improve texture and reduce redness
  • Diminish fine lines and wrinkles
Important: Start slowly if you have sensitive skin and always follow with a moisturizer to prevent irritation.

Day Preventive Treatment: Morning Vitamin C Protection

Why Use It Every Morning?

This vitamin C serum is a powerful antioxidant treatment that protects skin from environmental stressors, stimulates collagen production, and brightens skin tone. Key ingredients include tetrahexyldecyl ascorbate (a stable vitamin C derivative), acetyl zingerone, and bis(cyano butylacetate) anthracenediylidene. Daily morning use helps:
  • Slow signs of aging
  • Minimize sun damage
  • Reduce redness and improve skin texture
Pro Tip: Avoid over-application and do not use on irritated skin. Once skin is healthy, reintroduce gradually.
