- “This is a good option for retinoid newbies and for people with sensitive skin”▶ 1:22

Medik8$135.00- “I like how they have six stages because having a ladder of strength options helps different people choose a starting point that makes sense to them”▶ 2:07
- “The serum gets more and more creamsicle colored and the price goes up with every jump in strength”▶ 2:23
- “I think this line is nice, but it can be on the pricey side”▶ 3:43
- “Medik8 uses a patent protected stabilization method for their retinal”▶ 4:07

- “At 4, 8, and 12 weeks, the AlphaRet side was non-inferior to tretinoin at improving fine lines, facial redness, facial discoloration, and skin tone”
- “It was also less irritating than both retinol and tretinoin”
- “Unlike tretinoin which reduced skin hydration, AlphaRet increased skin hydration”
- “I really like this product because I have sensitive skin even though I hate how expensive it is”
- “If I completely ignore prices and I live in La La Land, it is my favorite over-the-counter retinoid”
- “My sensitive skin tolerates it well”
- “I like how the color isn't as scary as the stronger retinal's too”
