Description:  Peter Thomas Roth (PTR) Retinol Fusion PM Serum is a concentrated time-released microencapsulated vitamin A (1.5% Retinol) product.  This is a fragrance-free, oil-free product.  It also contains squalane (derived from sugar cane, not sharks), vitamins C (Ascorbyl Palmitate) and E (Tocopherol).  This serum is intended to be used at night following cleansing of the skin and prior to the application of heavier night creams or moisturizers.  It is supposed to assist with cell turnover through vitamin A, improve skin texture, and reduce the appearance of fine lines and wrinkles with an assortment of other chemical compounds.

All Retinol products are light and air sensitive.  Try to keep the bottle in a dark place at room temperature and expose it to as little air as possible.  Also, try to use up the contents prior to the expiration date for maximum effectiveness of the ingredients.

About Serums:  Since they were first introduced into the market about a decade ago, I have been a fan of serums.  I don’t like anything that feels thick or heavy on my skin and serums are much lighter than creams and thus easily absorbed into the skin.  I also find that the lighter consistency does not clog my pores and results in fewer irritations and breakouts than heavier products.  They also contain a higher concentration of effective ingredients so it generally  takes less product and time to produce positive results than thicker creams.

Morning Review:  Okay, so why am I providing a morning review for a product intended to be used at night?  Because after much trial and error, this is how I prefer to use this product.  The PTR Retinol PM Serum feels like a very light, almost watery oil, although it does not contain any oil.  It has almost no scent.  Because the consistency is almost like water, use it one drop at a time rather than a dropper full at a time, as it will just run all over the place and you will waste your product.

I like to use the serum in the morning following cleansing and toning and prior to the application of sunscreen, moisturizer or makeup.  It refines my pores, leaves my skin with a silky texture, and everything glides on easier and better following the application of the serum.  I also use this on my neck.  I actually find that the first ingredient, Cyclopentasiloxane (a silicone derivative), makes this product an effective makeup primer.  I have tried this on many clients and they agree.  This serum has never irritated my sensitive skin.  My clients have not reported any sensitivity issues.

Caution:  If you have never used a Retinol (vitamin A) product before, please only use this at night to start with.  If you have any tingling or burning, only use it every other night until you build up a tolerance for it.  Some people are highly sensitive to vitamin A.  Also, vitamin A can make your skin more susceptible to burning so that is why it is recommended for use at night.  You must wear an effective UVA/UVB sunscreen whenever you are using any kind of Retinol product to protect your skin from burning and photoaging.  I will provide an in-depth analysis of effective sunscreens when we get to those product reviews.

Morning Rating = 4 Stars

Evening Review:  At the end of the day my skin does not feel tight.  This serum helps to keep my skin feeling soft and smooth throughout the day.  For an added bonus to your skin, you may apply the serum following cleansing and prior to the application of any other night creams.  You can use this on your neck and décolleté, too.  I don’t like a lot of different products for the face, eyes and neck, so this works for me all over.

Caution:  This product should NOT be used in conjunction with any other products containing vitamins A and/or C.  The combination of the PTR Retinol Fusion Serum with other anti-aging products would probably prove too harsh and may lead to irritation and/or sensitivity issues.

Overall Review:  Peter Thomas Roth Retinol Fusion PM Serum is a very good Retinol product.  It does improve the texture of skin and makes it feel smoother.  I also like the fact that it makes my pores appear smaller which improves the application of makeup.  As far as removing lines and wrinkles, I have not seen any improvement in deep or fine lines and/or wrinkles.

This serum is suitable for the following skin types:

• All ethnicities;
• All ages;
• All sexes;
• Dry;
• Sensitive;
• Consistent;
• Oily;
• Combination.

Please note:  If you decide to buy this product I would advise you to stay away from discount re-sellers such as those found on Amazon or eBay, as there are some sellers that are marketing counterfeit products and this is a popular product that is frequently sold as authentic but is, in fact, fake.  If someone is selling this product for 50% less than the authorized retailers, you should be suspect of the authenticity.  If it sounds too good to be true, it probably is.  You don’t run any such risk when purchasing from an authorized retailer such as the ones at the top of this review.
