Frequently Asked Questions

What makes this serum different?

The difference is having many powerful, proven ingredients in one serum. The multitasking formula truly simplifies your daily skincare routine and provides visible anti-aging results.


How does it feel on the skin?

Skin Harmony Estriol Face Serum feels beautiful, refreshing and smooth.


Can makeup be applied over it?

Yes, simply allow it to sink into skin for one to two minutes.


Should I use it morning or evening?

You can apply it once or twice daily, so you can choose morning, evening or both!


Should I apply sunscreen?

Yes. We recommend using SPF daily.


What are Ceramosides?

Ceramosides are a patented natural source of phytoceramides, derived from French wheat (formulated to be gluten-free). Ceramosides are clinically shown with continuous use to improve the skin’s texture, hydration and firmness. Skin ceramides are lipid molecules found in high concentrations within cell membranes in the upper layer of the skin. They hold skin cells together, forming a protective layer that plumps the skin and holds moisture. They also act as a barrier against bacteria and environmental pollutants. Ceramides decline with age.


What skin type can use this product?

The serum is suitable for all skin types.


How many applications can I get from one bottle?

On average, you can expect about 100 one-pump applications.


Will estriol impact my hormonal balance?

Evidence suggests that estriol only stays in the dermis (skin).


How is estriol different than other forms of Estrogen?

Estriol is the least potent of the three estrogens: estradiol, estrone and estriol. Not only does it have weak estrogenic activity, levels are virtually non-existent, except during pregnancy. Topically applied, estriol does not penetrate well below the dermal layer. This means that there is minimal impact in places other than where it is applied. It is about 80 times less potent than estradiol. Despite its lower potency, topical application has been shown to effectively help with the changes we see in the skin as it ages.


Do the exfoliants linger on my skin?

The exfoliants in Skin Harmony Estriol Face Serum are very gentle exfoliants that can be used every day. Over time, they will assist in the gradual removal of dead skin cells.


Which plant is the estriol sourced from?

The estriol in Skin Harmony Estriol Face Serum is sourced from Wild Yam.


What are phenoxyethanol and tetrasodium glutamate diacetate?

Phenoxyethanol is a naturally-derived preservative. Phenoxyethanol has replaced parabens in more natural-based cosmetics and personal care products. Tetrasodium glutamate diacetate is a preservative booster and chelating agent. Compared to EDTA, it demonstrates enhanced preservative boosting power, and it is not toxic to cells or genetic material.


Is there any soy in the formula?

No, but the glycerin in the formula is extracted from soybean.


Is Skin Harmony tested on animals?


What is the Proposition 65 warning?

The purpose of Proposition 65 is to notify consumers that they are being exposed to chemicals that are determined by California to cause cancer and/or reproductive toxicity. The “Prop 65” warnings are only required under California law. Prop 65 standards are among the most stringent standards in place anywhere and are often far more stringent than federal standards. Consumers can decide on their own if they want to purchase or use the product. A Proposition 65 warning does not necessarily mean a product is in violation of any product safety standard, law or regulation. Our product meets all federal regulatory and safety standards. The warning is provided to allow consumers to assess their individual risk. The calculation used to determine the risk is - a person exposed to the chemical at the “no significant risk level” for 70 years would not have more than a “one in 100,000” chance of developing cancer as a result of that exposure.

What gives the serum its unique color?

The eye-catching pink tint comes from Vitamin B12.


Are there any artificial fragrances or colors in the formula?



Is there a satisfaction guarantee?

Yes, we recognize there may be a small percentage of consumers that will not be completely satisfied with the results of this formula. To ensure 100% satisfaction, we offer a 60-day money back guarantee from the date of purchase. Call 888-300-9181 or email for details.
