What did the company highlight?

LG H&H says Secret Essence first launched in 2009. For the fifth generation, it highlights 8,700 hours of fermentation and its proprietary ingredient CYTOSIS. The company also says its melting ceramide particles are 14.4% finer and the relevant ingredient is 2.12 times more abundant than in the previous product. That's the manufacturer's own comparison, not one against another brand.

An ingredient name or a fermentation time can't tell you whether a product suits every person's skin. So check the ingredient list and the precautions on the product before buying.

What sizes and prices were announced?

These are the prices in LG H&H's October 8, 2026 press release. We haven't verified whether promotional sets or retailer prices match them. Compare the size and the final amount before paying.

How should you read the usage-study claims?

The manufacturer also announced results for skin turnover and the skin barrier. It says the turnover test, for example, was conducted by P&K Skin Research Center in July 2026 with 31 women aged 20–59. Other measures had different sample sizes and periods.

These are the manufacturer's own results, obtained under limited conditions. They don't guarantee the same change across all ages and skin conditions. And the press release doesn't give enough detail to fully assess how each measure was obtained, so don't read the figures as an individual treatment outcome.

What if your skin is sensitive?

The US Food and Drug Administration (FDA) says cosmetics can cause allergic reactions in some people, and it advises checking ingredient lists and avoiding substances you know you're sensitive to. That's general cosmetic guidance, not a test of allergic reactions to this product.

If an ingredient has caused you trouble before, check the product label, and ask the manufacturer if you have any questions. If a rash, itching or another adverse reaction shows up, stop using the product and consult a health professional when needed.

Where is it sold?

LG H&H lists the sum37° official store, Olive Young online and offline, and department stores among its sales channels. Stock and sets can vary by location and time, so check before you go.
