    Dewy Skin

    The peptide serum may be a permanent staple in my skincare routine. Within the first week I noticed my skin evening out and plumping back up which is absolutely amazing. Paired with the 1% retinol serum I can see that I’ll quickly be back to healthy youthful skin. I have incredibly sensitive skin and I haven’t noticed any extreme irritation or rashes from the products from Inkey List, which is another huge plus.

    The only downfall is the bottle style, I don’t feel like a serum should come in a squeeze bottle. If you’re not careful you’ll get way too much product with no good way to put it back in the container.

    First photo is before and the last two are after using for a week.

    Very nice

    Haven't used it enough to see a difference yet, but I do like the consistency and how my skin feels after.

    Moisturizes well, absorbs quickly but be mindful to use just the right amount
