I use Serum of Plenty and Serum of Clear, so I'll post this review on both products.
My skin goals are to have clear, smooth skin. I've been striving to have great skin that means I don't feel the need to wear foundation of any kind to cover up marks or smoothen out skin tone. I first found Glory Oil and used it for my stretch marks as recommended by my sister, and then started using it on my face. I noticed it helped make my skin smoother and started fading marks.
I went ham using these products since the start of the year. I used them every day. After about a week, I started breaking out, and the tingling turned into stinging to the point it became unbearable. I looked at the reviews to see other's experiences, and noticed that the Eco Tan staff responded advising to use it once a week, and build up slowly so that your skin becomes more accustomed to the active ingredients. In Eco Tan's YouTube videos with Sonya, she always says "check ingredients, people!" - both Serum of Plenty and Serum of Clear have active ingredients that cause tingling and can cause 'purging'. So, instead of giving up on the products, I dialed it back to once a week, then gradually increased. From January to now March, I went from once a week to Mon, Wed and Thurs. The purging stopped, and the tingling stopped as well (I have sensitive skin).
My skin is now brighter and smoother. My severe acne scars (from teenage years which faded but still can be seen) have faded, as well as other marks and blemishes. All the bumps on my chin that can be seen in the light have faded.
I can tell you, as a dark-skinned mid 30 yr old who has had severe acne issues growing up and who has sensitive skin - these products work!
Don't give up just because you don't see results after one or two uses.
Don't give up because it tingles a bit.
Do what I did and after 3 months, you'll notice a different.
I love these products and I'll definitely keep using them. They are affordable, natural and they produce results.
I am also using both serums on my back after daily exfoliating (may be overdoing the exfoliating), but I have noticed a massive difference and all my marks are now starting to fade (confirmed by my faithful husband who applies it for me lol).
Try it!
