15% Vitamin C+ Clean Caffeine Energy Serum - Sérum énergisant à la caféine

4+ year staple

Going on 4+ years using this, and I really like it. I feel like it keeps my skin looking bright and refreshed, and I've definitely noticed a reduction in redness. I'm pretty sensitive to retinol and anything even close (skin peeling, redness, etc.), but this one has worked out well with my skin. It is definitely a bit tacky/sticky when you first put it on, but I always follow it up with the air whip moisturizer by YTTP and it balances that out. I also noticed I basically never get dry patches of skin anymore where my makeup clings with that combo (and their cleanser). I will say I feel like this product goes so fast when I use it though, and it's definitely not cheap. I use like 5-7 pumps on my face, neck, and decollete 6 days at least a week. A bottle typically lasts a month maybe less. I'm fair skinned, 39, historically had trouble with redness, sensitive to retinols/harsher chemicals, hormonal acne.

Great product

This is an effective product but I cannot justify the price. You can find cheaper from the ordinary or Inkey list that work just as well.

Repeat purchase!

I’ve gone through 2-3 bottles of this over the past year - long lasting and I find effective!

Buyer beware!

This product is horrendous. I consider myself to have a pretty resistive skin with daily use of vitamin C in am and retinol in pm. This serum caused me to have a horrible allergic reaction, including eye swelling and extr and ex , intense, itching, and extreme redness.

Allergic Reaction

I had a horrible allergic reaction from this serumMy face was covered in painful hives after using this serum.

Allergic Reaction

I too like others am experiencing an allergic reaction. My face is really swollen right now and itchy.

Love it

Feels great and noticeably evens out my skin tone. Others have noticed my skin looking brighter.

SEVERE ALLERGIC REACTION

What a nightmare. Three days ago, I applied this serum before bed, and since then my eyelids have been completely swollen and I’ve developed a painful rash across my entire face. I had to see a doctor and cancel all my plans because I look and feel awful. Reading through other reviews, I see I’m not alone—many people reported similar reactions. This product should come with serious warnings.

Allergic reaction

Gave me hives, bumps and itchiness. Horrible reaction

Final Sale for a Reason

Buyer beware. I bought this at full price. Like many of the others, I had a severe reaction on my face. I’m on day three and it doesn’t seem to be getting any better. Do not buy this product.

Best Vitamin C I’ve tried

This has been a staple in my morning routine for years. No other product brightens and reduces spots like this one for me

Super harsh, caused reaction

I love and use a lot of the YTTP products especially their cleanser, glow berry mask, and adaptogen moisturizer. When I applied the vitamin C, my face started immediately tingling and I washed it off right away. It was too late and the product made my skin super red and inflamed. I also do not have sensitive skin and have never reacted like this to a product before
