” ...deliver the right amount
of collagen...”
Hoax. Collagen has to be stimulated to increase from inside the skin. Topically, it’s too big to be absorbed.
If it has water AND vitamin c, it’s also worthless. The vitamin c is often significantly degraded by the water by the time it gets to the customer.
Are you by chance a dermatologist?
If so, can you recommend a gentle but effective anti-aging cream, serum, whatever for sensitive skin with long-standing but mostly stable rosacea?
