## How to apply

- Gently press 2-3 drops of the serum into your skin using your palms. Let it absorb completely for a minute ⏱ before applying your next product.

## Questions and answers

### How well does K-SECRET SEOUL 1988 work for dry sensitive skin?

This serum works moderately well for dry sensitive skin by offering anti-aging benefits and essential hydration through ingredients like retinal, bakuchiol, and glycerin. While it is generally safe and helps smooth the skin, products for this skin type typically need deep-hydrating components, soothing barrier support, and a nourishing texture to achieve the best results without irritation.
Sources: [The British Journal of Dermatology, 2019](https://pubmed.ncbi.nlm.nih.gov/29947134/), [Health Science Reports, 2025](https://pubmed.ncbi.nlm.nih.gov/41424674/)

### Which ingredients make this serum a good fit for dry sensitive skin?

Retinal, bakuchiol, glycerin, and macadamia seed oil make this serum a good fit by smoothing fine lines and keeping dry skin hydrated. To fit dry and sensitive skin even better, a treatment of this type needs rich moisturizing ingredients that lock in moisture and protect the skin barrier without causing irritation.

### What does Retinal do for dry sensitive skin?

Retinal may help smooth fine lines and improve skin texture, but for dry and sensitive skin it is unlikely to be a good fit on its own. This skin type needs products that include gentle hydrating ingredients like hyaluronic acid and glycerin to lock in moisture and protect the skin barrier.
Sources: [Journal of Drugs in Dermatology, 2024](https://pubmed.ncbi.nlm.nih.gov/39496127/), [Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473963/)

### What does Ginseng Root Extract do for dry sensitive skin?

Ginseng root extract helps dry sensitive skin by locking in moisture and calming irritation to keep your skin feeling smooth and comfortable. It supports collagen to help maintain firmness while reducing the rough patches and redness common in sensitive skin.
Sources: [Journal of Ethnopharmacology, 2007](https://pubmed.ncbi.nlm.nih.gov/16890388/), [Journal of Ginseng Research, 2017](https://pubmed.ncbi.nlm.nih.gov/28123324/)

### Where does it go in a skincare routine for dry sensitive skin?

This treatment goes in the evening routine after your toner and before your moisturizer. Dry and sensitive skin of this type needs a gentle product with hydrating ingredients and soothing plant oils to maintain moisture balance while minimizing fine lines.
Sources: [The Journal of Dermatological Treatment, 2022](https://pubmed.ncbi.nlm.nih.gov/32239984/), [Journal of Drugs in Dermatology, 2025](https://pubmed.ncbi.nlm.nih.gov/40327583/)

### Can I use this serum with AHA, and in what order?

It is best to use this serum and AHA on alternate nights rather than together to help prevent your skin from becoming dry and irritated. This type of skin needs products that combine gentle smoothing ingredients with soothing plant extracts and heavy moisture to keep the barrier calm.

### How often should I use it?

This serum works for your dry sensitive skin in the evening, as treatments with actives fit best at night for safety and simplicity. To keep your skin soft and calm, a product for this skin needs nourishing plant oils and gentle hydrators to support the moisture barrier.

### Can this serum clog pores, cause breakouts or purging for dry sensitive skin?

This serum is unlikely to clog pores or cause major breakouts on dry sensitive skin, though initial mild breakouts may occasionally happen. To work best for this skin type, a product of this kind needs extra soothing plant extracts and barrier-supporting oils that keep the skin calm and deeply moisturized.
Sources: [Health Science Reports, 2025](https://pubmed.ncbi.nlm.nih.gov/41424674/), [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

### Is it fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol.
