1.      What is a face serum?

Face serum is a skincare product that is designed to reduce the signs of aging. It contains active ingredients as well as inactive ingredients which combined gives your skin the boost it needs to moisturise the skin and help It look its best. The ingredients in face serums can include Vitamins, Antioxidants, minerals and acids all specifically formulated for various skin concerns. In this article we will help you learn about face serums and also which to choose for your specific skin type.



2.      Is serum a lightweight moisturiser?

Yes, face serum is effectively a lightweight moisturiser. The reason for this definition is that moisturisers typically absorb into the skin to help moisturise and hydrate the skin. Because face serum does this, we can class it as a moisturiser. However, they provide more than just moisture. The blend of ingredients within face serums acts more as a defence barrier to help your skin throughout the day when applied just before a typical moisturisers such as “Obagi Hydrate Luxe Moisture Rich Cream”. In general moisturisers tend to be thicker cream based product that is applied after serum to lock in the goodness of the serum for a longer time period. In summary, a face serum is a targeted treatment and a moisturizer is a more general hydration and protection.



3.      Why use a face serum?

There are a number of reasons why you may decide to use a face serum, these are some of the main reasons people start and continue to use them:

  • Antioxidant Protection: Obagi C Serum 20% contains vitamin C, which is a powerful antioxidant that can help protect the skin from damage caused by free radicals
  • Brightens the skin: Vitamin C is also known to help brighten the skin, reduce the appearance of dark spots and even out skin tone.
  • Aids Collagen Production: Vitamin C plays an important role in the production of collagen, which helps to keep the skin firm. Obagi C Serum 20% can help to boost collagen production and improve the overall appearance of the skin.



4.      How To Use A Face Serum?

To use Obagi C-Serum, firstly you should cleanse your face followed by patting it dry. Then you can apply a small amount of the serum to your face and massage it in gently. The aim here is to focus on areas of your face that show visible signs of pigmentation, aging or wrinkles. It is recommended to use the serum in the morning and at night before you moisturise. In addition to this, you should use a suitable sunscreen such as “Obagi Sun Shield” during the day for maximum effect.

It is important to note that face serums contain potent ingredients and due to this fact, we highly recommend booking a consultation with us before you start using face serums. In addition to this, we recommend that you apply the face serum to a small area such as the back of the hand before applying to your face to ensure that you don’t have any adverse reactions.



5.      What Is The Best Time To Apply Face Serum?

The best time of day to apply face serums will depend on the specific serum you choose and its intended use. In general, it is recommended to apply serums in the evening, just after your cleansing routine and before moisturising. The reason for this is that while you sleep yours skin is relaxed and in a much more receptive state when compared to during the day. This helps the ingredients absorb deeply into the skin.




6.      What is the best face serum?

The best face serum for you depends on your skin type. We all have slightly different skin types and because of this the best one for you may not be the best for someone else. Analysing the 3 popular face serums by Obagi we can determine the following:

  • The Obagi C-Face Serum 10% is the lowest concentration of the three and is best for those with sensitive skin or if you are just starting to use face serums as part of your skincare routine.
  • The Obagi C-Face Serum 15% is a slight step up from the 10% concentration (as the percentage suggests) and is best for those with normal to oily skin.
  • The Obagi C-Face Serum 20% is the highest concentration in the Obagi Professional C range and is best for those with mature skin.



7.      How to choose the right face serum?

If you are confident of your skin type then you can use the guide in point 6 to work out which one will be most suited to your skin type. However, if you are unsure we recommend that you book a consultation with us to help determine which face serum is likely to work best for you.



8.      Key benefits of using face serum

There are many benefits to using a face serum when you get to a certain age but the key benefits are as follows:


  • Your skins texture will look smoother and its appearance in general will look more youthful. This is due to increased collagen content which will give your skin a firmer look.
  • The open pores on your skin will be less visible due to a reduction in their size.
  • Whiteheads and blackheads will be reduced.
  • If you suffer from dry skin and fine lines around the eyes these lines will appear reduced and the dryness will be reduced.
  • Scars, spots and pimples will appear reduces due to the antioxidant nature of the serum.



9.      How to get the most out of your serum?

To get the most out of your face serum the key is to not apply too much. Applying large amounts to your face can sometimes cause the skin to become irritated. So start with small amounts.

To make the most of your new face serum it’s important to make sure you cleanse the skin thoroughly first. The reason for this is that if you skin contains dead skin or dirt which should be removed prior to using face serum.  If your face is not clean, the serum may not absorb quite as effectively therefore not giving you the maximum benefits.

When cleaning your face before applying face serum be sure not to use really hot water as this will open your pores and may make the skin sweat. The use of slightly warm water Is best as this relaxes the skin for better absorption.

If you suffer from dry skin then it may be best to apply when the skin is still damp. However, if you have sensitive skin applying the serum to dry skin may suit you better. As with all face serums you should test this on a small area first such as on your wrist just to make sure your skin reacts well to the serum.

Do not apply face serums after you have moisturised. If you do so, the serum will not be absorbed into the skin and the moisturiser will act as a barrier to the serum meaning it will not be effective. The trick is to always apply any moisturisers after you apply a serum, simple!



10. What is the ideal age to start using a serum?

Most face serum users start when they are in their 20s or 30s, as this is when many people start to notice the first signs of aging, such as fine lines and wrinkles. However, there is no specific age at which it is appropriate to start using a face serum. What determines whether or not you should be using a serum is purely down to your specific skin type or concerns.

Face serums are sometimes often used by younger adults where they have a specific skin concern, hyper pigmentation, dullness or dryness of the skin. To discuss your skincare needs you can book a consultation with our in house doctor for professional expert advice.



11.      Does It Take Long For Face Serum To Work?

The time it takes for results to show varies. It varies depending on the individual and the specific product being used, but generally it takes several weeks to see results when using a face serum. It’s important to use the product consistently and as directed by your doctor or skincare specialist. It’s also important to note that different types of serums may target different skin concerns, so the results and the time it takes to see them do vary.

The Obagi Professional-C Serum range of product, according to Obagi, many people see noticeable improvements in the appearance of their skin within 4 to 6 weeks when used consistently.



12.      What Is The Difference Between Serum And Face Oil?

Face serums and face oils are both skincare products that can provide hydration and nourishment to the skin, but there are some key differences between the two as we will explain.


Face serums are typically water-based and have a lightweight, fast absorbing texture. They are formulated with high concentrations of active ingredients, such as vitamins, antioxidants, and hyaluronic acid, and are designed to target specific skin concerns, such as aging, wrinkles, or hyper pigmentation of the skin.


Face oils, on the other hand, are oil-based and have a thicker texture. They are made from a blend of natural oils and are designed to provide hydration to the skin. They can also provide a protective barrier for the skin, helping to lock in moisture.
