Road Trip! My Must Have Products For Traveling
Road Trip! My Must Have Products For Traveling
Okay so I’m going on a stay-cation. Meaning I’m not leaving the town I live in I’m just staying at a house that’s not mine. Trying to sprinkle a lil spice into my life. Anywho As I was packing I thought it would be cool to share what I put in my travel bag. First👏🏾 of 👏🏾All👏🏾 If it’s travel size it’s coming with me! Also My skincare routine is a tad bit different when I travel. Back in the day when I traveled I felt like my skincare routine went out the window but this would throw my skin all outta wack. Consistency is key when you have sensitive and acne prone skin! However to my defense I felt like I would need a separate luggage for everything I used on my skin because most brands don’t make travel sizes unless it’s a staple product. Hopefully this changes🤞🏾 Thankfully now, most of my must haves come in travel sizes so I can stick somewhat close to my routine when I’m away. So, here is the break down! I start with Kiehl's - Ultra Facial Oil-Free Cleanser It’s in the same oil fee collection as the gel moisturizer I like from Kiehls. I follow up with a toner after cleansing pixi - Clarity Tonic I use a bit of Kiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C This is new to my routine I’ll share my thoughts later Then moisturize with #Kiehls - Skin Rescuer[products]#[FiveStars] This is my second favorite lotion from kiehls. I mainly carry this when I travel because the moisturizer is in a squirt bottle. I don’t like packing my oil free gel moisturizer because the shape fits awkwardly in most of makeup bags. Also selfishly😅 sometimes when traveling with other people some will go dipping there fingers in my moisturizer to try it if it’s left out in the bathroom. I have no problem with other people trying it. However It’s just the finger dipping that bothers me. I don’t even dip my own fingers in it I use a qtip so I don’t contaminate it with other products that I might have on my hands. I wrap up my routine with HUDA BEAUTY - Get Even Rose Face Oil I reviewed this already and y’all know how I feel about it. 😍 I kept the small bottle from the holiday kit and I refill it from my bigger bottle so I can take it with me when I travel. This bottle is glass so I reuse it especially since I reuse it for the same product. Supergoop! - Unseen Sunscreen Broad Spectrum SPF 40 Sunscreen is always a must! #Ebin - Ebin 24 Hour Edge Tamer[products]#[FiveStars] & most importantly edge control because Honey wherever I go the edges must be laid and this gets the job done right! ✅

{Kiehl’s Butter Milk Lip Treat
{Kiehl’s Butter Milk Lip Treatmeant 🧈🥛❤️}• When chapstick doesn’t seam to cut it but this product! It instantaneously mends cracked lips 👄 Making your kiss super silky soft! {Midnight Recovery Concentrate} • When applied to skin you are surrounded with a smell of lavender, relaxing you and making you stress free ! I love this product, I mostly use it at night. That’s when the ingredients are most at work. At night is when our skin is most able to repair itself. When you wake up your skin feels amazing and renewed. {Ultra Facial Moisturizer} - one of my favorite moisturizers! (All Skin Types) Easily absorbs into the skin. Helps with optimizing skin tone and ultimate hydration. Leaving a cool refreshing feeling on the face. Vitamin A & E SPF 30 {Powerful-Strength Line Reducing Concentrate with 12.5% Vitamin-C & Hylauronic Acid } Love love love this one! But let me start out by saying Vitamin C products are amazing! But did you know if there is too much of it in a product, it actually doesn’t do anything ? This product has the perfect amount of Vitamin C and as you apply it you feel a warming sensation ( my favorite part ). It helps reduce dark spots and uneven skin tone. Also gets rid of fine lines, wrinkles and is pore refining! Amazing product ! Must try all of these together !

Best👍 or Worst👎 Vitamin C Products 😲Same Ingredients, Different Results!
Best👍 or Worst👎 Vitamin C Products 😲Same Ingredients, Different Results!
Recently, on various platforms, many people are recommending skincare products containing vitamin C. Because this ingredient can not only effectively whiten, but also has a certain anti-aging function. I am a skin type who likes oily skin, so I hope to have products that have both oil control and whitening effects for my dark spots. Kiehl’s Powerful-Strength Vitamin C SerumKiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C $70/50ML This product comes from Kiehl's. Because I like Kiehl’s brand very much, I bought this product on the basis of trust. I have to say that a trustworthy brand will not let me down. After using this product in the morning and evening, the biggest feeling is that the skin does not become dull and the pores are thinner. Kiehl's uses exclusive polyol-C technology in this product, mixing 12.5% of high-concentration vitamin C and solid small molecule hyaluronic acid, but it can achieve the effect of non-interference. A potent Vitamin C serum formulated with 12.5% Vitamin C and Hyaluronic Acid. Such components can achieve antioxidant and anti-free radical effects. Regarding the use, we need to pay special attention. This ingredient is very afraid of ultraviolet rays, so be sure to take adequate sun protection. CLINIQUE Fresh Pressed Daily Booster with Pure Vitamin C 10% CLINIQUE - Fresh Pressed Daily Booster with Pure Vitamin C 10%$79 This is another product containing vitamin C. The biggest feature of this product is its packaging, which separates vitamin C from essence, and keeps the activity of vitamin C to the greatest extent. On the other hand, this tells the user that you must use a vial in a short time, otherwise, the ingredients will be invalid. This product has a concentration of 10% and is very friendly to sensitive skin. However, the moderate content of ingredients means that there is no obvious effect, and there is no big change after using it for a while. On the contrary, I don't really like the texture. After using this product, if you need make-up, it is unacceptable.

I’ve never really been a big fan of Vitamin C because of how unstable I have found it to be, honestly I don’t know if I will be using Vitamin C in my routine after I use these up. I want to simplify my routine, and by simplifying I mean reducing the number of products and thus ingredients on my face, which will hopefully increase the efficacy and thus I will see better results in the future. Right now, I am using Vitamin C because it is said to be very efficient in helping protect the skin from sun damage and consequently boosting the effects of the sunscreen. DERMA•E - Vitamin C Concentrated Serum As soon as I wake up and rinse my face, I apply this serum first. It smells amazing, citrusy. It’s a good texture, a thin gel which dries quickly on the skin, you definitely feel it seeping in your skin. TONYMOLY - Vital Vita 12 Synergy Ampoule The ampoule is like any other, watery and it gets a bit sticky as you pat it into your skin, I believe the heat of palm does that! I brought this on a whim but I don’t feel like it was wasted money. It has a good texture and does a good job supporting the effectiveness of the Derma-E serum. The Ordinary - Alpha Arbutin 2% + HA Alpha Arbutin is said to be very useful for pigmentation, the Hyaluronic Acid is an added bonus. Fantastic product. Does what it is supposed to. Kiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C I like to mix this with my face cream because it’s too oily to use on its own. I think it does a decent job hydrating my skin, and I have noticed an increase in how quick my skin fades. Kiehl's - Ultra Facial Cream I feel like it’s a pretty basic moisturizer, I have no problems with it. I just feel like I could get the same benefits from any other moisturizer for much less. Neutrogena - Clear Face Oil-Free Sunscreen SPF 55 The sunscreen is absolutely wonderful, just wish it didn’t burn when it got in my eyes. The price point as well as the matte finish make it an absolute go to product! (Also makes for a phenomenal primer)

My skin type is combo oily and my skin concern is acne, acne scars and dullness. . Propylene Glycol: A slightly thick liquid that has no scent or color. It is used in low concentrations in many products as a humectant and epidermal delivery agent. Basically that means it helps a product penetrate into the lipid bilayers of the epidermis and to help stabilize the formula so that it doesn’t change in extreme temperatures. It’s main functions are that it attracts water, lightly moisturizers, addresses visible signs of aging, enhances penetration, prevents water loss, and is safe for acne-prone skin. . Controversy: It seems to be common that “Clean Beauty” says to stay away from this ingredient. Misinformation about data that shows dramatic stores with prolonged use cause liver and kidney damage. However, these studies were done with the effects of inhalation or ingestion with large concentrations and over long periods of time. These levels aren’t relevant to how much is used in skincare or the form of use with skincare. There has also been confusion and blurred lines with its association with other glycols, like ethylene glycol (not used in cosmetic formulations). Both propylene and ethylene glycol are used in automotive applications and has caused skin irritations in some people, but when used at 100% concentration. It has no toxic effects when used topically and in the concentrations commonly used cosmetic formulations. . My Experience: I had honestly not heard about this ingredient until I started researching for this topic. I have been using the Kiehl's - Powerful-Strength Line-Reducing Concentrate 12.5% Vitamin C for the past couple of weeks and have noticed an improvement in my acne scars/overall glow/radiance. It hasn’t had an negative effects on my skin or caused any sensitivity. It is very lightweight and easily absorbs into my skin without leaving behind a greasy feeling. I also haven’t had any issues with pilling or painful reactions.

VITAMIN C HOLY GRAIL

Ooo ladies and gentlemen. This is going to become a cult favorite of mine. It’s hella expensive but I decided to pull the trigger. I tried the sample and had to purchase a full size. Not only does this contain 12.5 % Pure VC it also contains hyaluronic acid. Double benefits in one. It has this warming effect that feels so amazing once you rub it in. Someone my freckles aka sun spots have lightened. I have definitely seen some of my forehead wrinkles smooth out. Hopefully over time I’ll see more tightening. I have one cheek that is not as firm as my other. I’m praying this will do the trick. So far it’s been amazing.
