What the gurus are saying

Double the strength of a lower-potency retinol eye cream sounds intense, yet this one spreads easily, absorbs fast and leaves the under eye plump while smoothing fine lines. It suits anyone already comfortable with retinoids, and newcomers are told to start twice a week at night on dry skin, then ramp up. If winter leaves your eyes dry and crinkly, you may want something over it.

"This is the K-Secret eye cream. It has soy bean and fermented bean extract and some retinal in it, but I didn't feel it was that spicy. The texture is pretty thick, [...] thicker than [...] a classic eye cream, but it spreads so well and I feel really comfortable using it, it reminds me of my favorite eye cream from Sana, an affordable Japanese brand. I also like the packaging because you can apply it more precisely, it's easy to apply, so I'm giving this an A tier."

"This is a high potency eye cream that's going to snatch the under eye, minimize fine lines and wrinkles and smooth everything out. I adore it. What I think is great is if you're someone that's using a lower potency retinol eye cream but you want a higher potency option, go for this in the 4%. This is double the strength, and so definitely packs a punch. I like the fact that we now have different strengths when it comes to eye products."

"It's got this hydrating gel-like consistency and it absorbs really fast, leaving the skin around the eye area actually quite plump and hydrated. This is great year round, but if the skin around your eyes gets really dry and crinkly in the winter time then you may need something over it. [...] I've been using this around my eyes and so far it's been great. This formula is kind of a well-aging powerhouse."

"This is a really good product if you are more experienced with retinoids or if your skin is just really not sensitive to them. [...] If you're introducing a retinol to your routine, I'd highly recommend adding it to your routine slowly. For example, use it twice a week at night at first and then slowly ramp up. I'd also recommend using it on dry skin and using it with moisturizer and getting rid of any irritating products in your routine while you're starting on it."
