Because it is a blend of 1% retinol and trichloroacetic acid (TCA). Here is exactly what these active ingredients do for your skin:

1% retinol encourages skin cells to turnover at a faster rate, making way for new skin. Retinol also prevents collagen breakdown, and thickens the deeper layer of the skin where wrinkles form keeping them at bay longer and softening fine lines that have already formed.

TCA (trichloroacetic acid), a chemical peel ingredient, causes skin rejuvenation by an exfoliative process of removing the outer layer of dead skin cells to reveal more smooth, firm, radiant and evenly toned skin. 

It's completely normal for skin to feel dry, flaky, and look pink or red during the introductory phase. This is part of the process of adapting to increased cell turnover, and can last 2-6 weeks. It is NOT a sign that you are too sensitive to the ingredients or that you cannot tolerate the product.

Purging is also a normal part of the introductory period. With increased cell turnover, oil and dead skin cells trapped within pores clear out much quicker than they would have otherwise, which can look like new blemishes for a week or so. Stick with it — the treatment for the breakout is the exact ingredients causing it.

Remember, the active ingredients in Perfect Change Serum reveal fresh, new skin that is more vulnerable to harmful UV rays. Be sure to use SPF each morning and wear a wide-brim hat during prolonged sun exposure.

This product is NOT ok to use if pregnant or breastfeeding.

In the evening after thoroughly cleansing and drying your skin, dilute PCS by mixing 1-2 pumps with an equal amount of an oil-free fragrance free moisturizer (such as Dew). Apply the mixture evenly over your entire face every night (do not apply to the eyelids or skin directly under the eyes). It is ok to use every other night if necessary, but be sure you are not using it less than 3-4x per week. The diluted mixture can help the skin adjust more easily for the first 4 weeks. Once the skin is adjusted, then you can use PCS undiluted and layered separately from your moisturizer application by about 10 minutes.

To further support the skin with deep hydrating nourishment, layer The One Serum underneath PCS in the evening, and before your morning moisturizer too. This product can do wonders for comforting the skin.

A note about moisturizers. I highly recommend investing in one of the PRFCT SKIN moisturizers to mix with Perfect Change Serum if you are purchasing it for the first time. Dew is the ideal pairing because it is a clean formula without fragrances, dyes, parabens and dimethicone so it should not cause any additional irritation. Please see the moisturizers collection to decide which one is best for your skin type.

PCS is available in a mini size as well.

Remember, the active ingredients in PCS are revealing fresh new skin that is more vulnerable to harmful UV rays. So, be sure to use a daily SPF each morning. A couple of our faves are Shade and Perfect Powder. Always wear a wide brim hat during prolonged sun exposure.

PCS is ok to use on your neck. However, the neck can be a very sensitive area, and often takes much longer to build tolerance. Consider mixing 1 pump Perfect Change Serum with 2-3x the amount of Firming Neck Cream and slowly increasing the strength over a longer period of time.

This product is NOT ok to use if pregnant or breastfeeding. Take a look at the safe mama collection for ways to keep your skin looking great while keeping your baby safe. 

This product uses an airless pump technology that may require priming when using the product for the first time (or anytime air is allowed into the bottle). Airless packaging helps to keep air and contaminates out of the product and allows for use with little to no waste. However, sometimes they do malfunction. To prime the dispenser, place the lid on the pump, turn it upside down, and tap it several times strongly in the palm of your hand. Then attempt pressing the dispenser multiple times until product is revealed. This should do the trick. If you are still not able to dispense any product after 15-20 pumps, use a large paperclip in the hole on the bottom of the product. Push the paperclip into the hole until you feel a ‘give’. Again, attempt pressing the dispenser multiple times until product is revealed.
