The Cathy Doll Collagen & Hya bedtime ritual, six steps for visibly firmer, plumper, more radiant skin by morning.
Step 1: Cleanse
Wash with the Cathy Doll Collagen & Hya Mousse Cleanser. Removes makeup and impurities while delivering the line's first dose of collagen and hyaluronic acid.
Step 2: Tone
Sweep Cathy Doll Collagen & Hya Toner & Essence across the face. Preps skin to absorb the next steps.
Step 3: Treat
Press 2 to 3 drops of Cathy Doll 15% 8 HYA Ampoule into damp skin. Concentrated hydration with 8 forms of hyaluronic acid and barrier support.
Step 4: Eye Care
Roll Cathy Doll Collagen & Hya Eye Serum under eyes and on lid creases. Targets fine lines and dark circles.
Step 5: Moisturize
Choose your finish based on the night:
• Every night, apply Cathy Doll Collagen & Hya Day & Night Cream (2% collagen) for your daily collagen care
• 3 to 4 nights per week, swap to Cathy Doll Collagen & Hya Sleeping Mask (3% collagen, 11 peptides) for intensive overnight repair
Both products are designed to work together, the Day & Night Cream is your daily essential; the Sleeping Mask is your premium intensive treatment.
Step 6: Wake
Rinse with lukewarm water in the morning. Reveal firmer, plumper, more radiant skin.
Caution: For external use only. Avoid contact with eyes. Discontinue use if signs of irritation occur.
