Questions and answers
What makes Paula's Choice PRO Retinaldehyde Dual-Retinoid Treatment a great fit for mature skin?
This treatment is a great fit for mature skin because it uses retinaldehyde and retinol to promote skin renewal and smooth out fine lines, while niacinamide helps repair the skin barrier. Soothing ingredients like bisabolol and licorice root extract are also included to keep normal skin calm and comfortable.
Which ingredients make this treatment a good fit for mature skin?
Retinaldehyde and retinol are the main ingredients that help smooth fine lines and renew mature skin, while niacinamide and soothing plant extracts keep it calm and comfortable. These ingredients have a strong safety profile and are well supported by clinical studies for reducing the signs of aging.
What does Retinal do for mature skin?
Retinal helps smooth fine lines, improve uneven skin tone, refine texture, and tighten pores on mature skin. It may also boost skin thickness and elasticity over time while keeping irritation low compared to stronger options.
Journal of Drugs in Dermatology, 2024Journal of Cosmetic Dermatology, 2018
What does Retinol do for mature skin?
Retinol helps smooth out fine lines and wrinkles while improving overall skin thickness and firmness over time. It may also cause temporary dryness, scaling, or stinging as your skin gets used to it.
Where does this treatment go in a skincare routine for mature skin?
This treatment goes in the evening routine, placed after cleansing and toning and before moisturizing. Putting active treatments in the PM helps keep things simple and offers extra safety around sun exposure.
Can I use this treatment with vitamin C, and in what order?
You can use this treatment alongside vitamin C by applying vitamin C in your morning routine and this treatment at night, as retinoids are best used in the evening. This separation helps reduce the likelihood of skin irritation while allowing both ingredients to work effectively.
How often should I use this treatment?
This treatment is a great fit for your mature skin and is meant for the evening routine. Start using it once a week, and if your skin feels comfortable and you see good results, you can carefully use it more often.
Can this treatment clog pores, cause breakouts or purging for mature skin?
Yes, this treatment may cause a temporary purging phase with breakouts as it speeds up skin renewal for mature skin. Ingredients like retinaldehyde and retinol help smooth fine lines, but this increased cell turnover can initially bring underlying congestion to the surface.
Is this treatment fragrance-free and alcohol-free?
Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
