Disclosure: This post is brought to you by Clarins.

As a beauty blogger, I test dozens of skincare products on a regular basis and frankly speaking often times I only have time to test each product for a few weeks and then it stays half-used simply because I have to move on to other products. There are some skincare goodies though that I continue using for months and even years. Today we’ll be talking about “my Holy Grail” products that I can’t imagine my life without. These are all the skincare products that I repurchased at least twice — and can’t recommend enough.

#1 Clarins Double Serum

My introduction to the brand happened back in Russia where I’m originally from. My mom is a real skin care junkie (I guess, my love for beauty products in generic!) and Clarins is one of the brands she’s been using for years. Even though I always had my own skincare products (in fact, I started my three-step skin care routine when I was about 12), every now and then I was sneaking her Clarins serums and creams as these always look so luxurious to me and I wanted to have the great skin my mom had.

One of the first products by the brand that I purchased for myself when I came to America, was Clarins Double Serum. Designed to promote firm skin and improve radiance, this miracle product turned out to become a perfect match for my dehydrated and prematurely aging skin. I love the serum because it’s full of exceptional ingredients that help to smooth, nourish, and protect skin. I also appreciate the fact that Double Serum is a multi-purpose product that you could use both during the day and at night — which is a big money saver as you don’t need to purchase individual serums for a.m. and p.m. Overall, when people ask me if there is one serum that I could recommend, that is it — Clarins Double Serum. Period!

This season, the brand re-introduced the iconic serum and made it even more perfect (is it even possible?) The new Clarins Double Serum now features a dual pump packaging which allows distributing just a perfect amount of product, depending on the current condition of your skin or the climate you live at. For instance, I use a small pump option in summer when my skin is naturally better hydrated. During the cold season, I’m planning on using more product so I’ll use the big pump option.

I know that some people are afraid of the change, especially when it comes to skincare products. My mom, for instance, stocks up on her favorite products the moment they are about to get discontinued. But with the Clarins Double Serum situation you don’t need to rush to your closest beauty store to get a backup of your favorite serum — the new formula is as good as the old one!

Shop: $89 for 1 fl.oz. and $122 for 1.7 fl.oz. at ClarinsUSA.com or at Bloomingdales.com.

#2: La Roche-Posay Thermal Spring Water

Here comes another story about my upbringing in Russia. Similar to many other European countries, La Roche-Posay is available in almost every Russian pharmacy so my introduction to the brand happened earlier in life. When I was just starting with makeup, I used La Roche-Posay Thermal Spring Water before applying makeup so my foundation looks more natural. Almost a decade later, I continue using this thermal water on a daily basis.

While thermal water is suitable for any season, I especially often reach out to it in summer. There is something super enjoyable in spritzing my face with refreshing thermal water a few times a day and on the beach. It’s also essential for me to have a can of this thermal water in my office. I feel that air conditioners are negatively affecting my skin and I minimize the drying effect of air conditioned air by using a naturally soothing and protecting thermal water by La Roche-Posay.

#3: Paula’s Choice Skin Perfecting 2% BHA Liquid

I was a late adopter of this cult toner, but once I tried it I never stopped using it. Technically, it’s not a toner though but an exfoliating liquid that contains salicylic acid which helps to even out the skin tone and unclog pores. I often describe the texture of Paula’s Choice BHA Liquid as dry toner which means that the product momentarily absorbs into skin and leaves it clean and refreshed.

You probably heard dermatologist talking about exfoliating your skin regularly and in many situations, it doesn’t actually mean that you should scrub your face with abrasive peels every single day. My personal preference when it comes to exfoliating is using a combination of BHA and AHA peels that I switch every single day and apply only at night. Basically, we are talking about glycolic and salicylic acids that gently exfoliate dead cells and improve the texture of your skin.

Personally, I noticed a tremendous difference when I started using incorporating these acids into my skincare routine. And if you are thinking of doing the same, I can’t recommend enough of starting from this BHA liquid. I’m not joking when I’m saying that I already finished three full-size bottles of this exfoliant — it’s literally that good!

Shop: $29 for 4 oz. and $9 for travel size at PaulasChoice.com.

#4: Lancome Bienfait Sunscreen UV 50+

I guess I have two problems — being a super pale girl and having very high standards for sunscreens. This summer I was planning on writing a roundup of the best sunscreens and I ended up disliking the majority of samples that were sent my way. Some of them were too thick, others caused breakouts, and the others were not working in combination with my favorite foundation. The only new product that passed the test was Lancome Bienfait Sunscreen UV 50+ as it features a super gentle and fast absorbing formula that totally works for me.

In addition to the fact that I love the texture of this sunscreen, I have to mention it’s compatibility with the majority of foundations that I have in my collection. There is something super smoothing and perfecting about this sunscreen that I don’t even have to use the primer before applying a foundation! Another important moment is that the formula of this sunscreen is oil-free which perfectly works for my acne-prone skin so I have no breakouts. What else to wish for in a perfect sunscreen? Personally, I’m just obsessed with it!

#5: Dermalogica Nightly Lip Treatment

That’s the only product that I just recently started testing, but it’s already on my Holy Grail list. Why? Because it helped me to get rid of a super unhealthy habit of applying petrolatum on my lips at night. I’m not sure if you heard about it before, but petrolatum is a derivative of oil refining. While this ingredient is not openly criticized for causing any danger, but something tells me that if it has something to do with petroleum it’s probably not that good for my health.

What I started using instead is Nightly Lip Treatment by Dermalogica. This lip product feels like a thick cream on my lips and it works even better than petrolatum! After applying I don’t feel the product on my lips at all, but in the morning my lips feel super hydrated and cracks-free. What I also noticed after switching to this lip treatment is that I need to use less lip balm throughout the day. Somehow my lips are constantly staying hydrated so I don’t need to re-apply a nourishing lip product every hour or so (as I used to do before!). In other words, this nightly lip treatment not only dramatically helps me with my constantly chapped lips, but also helps me to save time on being a lip balm addict!
