Pink Algae Pro-Retinol Moisturizer vs Argan Milk Microdroplet Serum
These are different steps, not rivals. The Pro-Retinol Moisturizer is the treatment-and-moisturizer step for fine lines; the Argan Milk Serum is a lightweight hydrating first layer that preps skin for whatever follows. At the latest prices, the moisturizer is cheaper: $42.75 at Mercari as of November 3, versus $60.00 at Sephora for the serum. Buy the moisturizer if you want one step that targets wrinkles; buy the serum if dehydration is your main complaint or your skin reacts to retinol.
Today the Pink Algae Pro-Retinol Moisturizer costs $17.25 less at its best price.

Questions and answers
- Which is better for fine lines and wrinkles?
- The Pro-Retinol Moisturizer. It is the one with a wrinkle active, and the brand reports 96% saw improvement in the look of wrinkles in 7 days. The serum smooths the look of lines by hydrating them, not by resurfacing.
- Can I use both together?
- Yes. Apply the Argan Milk Serum first, then the Pro-Retinol Moisturizer on top. The serum is designed to prep skin for the products that follow.
- Which is better for sensitive or dry skin?
- The serum. It is built for sensitive and driest skin and has no retinol. The moisturizer is formulated to be non-irritating, but it still contains Pro-Retinol.
- Is the serum worth $17 more?
- Only if you want a hydrating first layer. Per ounce it costs about $60 versus about $25 for the moisturizer, and it does not replace a moisturizer.
- Which lasts longer?
- The moisturizer, on size alone: 1.7 fl. oz. versus 1 fl. oz. Used twice daily as directed, the serum runs out first.
- Which one should I buy first?
- If wrinkles are your concern, start with the moisturizer at $42.75 at Mercari as of November 3. If tight, dehydrated skin is the issue, start with the serum at $60.00 at Sephora.
