This fit is calculated for the concerns frequently associated with dry skin: flakiness, tightness, dehydration, fine lines, and wrinkles. For scores based on a full skin profile (12D face scan, goals, preferences), use the Lovi app.

Works for dry skin; other serums fit it better.

## Why this fit

- Offers moderate skin rejuvenation for your dry skin due to retinaldehyde and hyaluronic acid, which hydrate and smooth texture, but lacks specialized ingredients to directly address dryness.
- Glycerin and hyaluronic acid provide humectant action supportive for dry or flaky skin, though insufficient emollient ingredients like caprylic capric triglyceride are present to fully address dryness.
- The formula is safe for your dry skin, with no risks of irritation due to the absence of prohibited or harsh ingredients.

## Questions and answers

### How well does Medik8 Crystal Retinal 6 work for dry skin?

Medik8 CRYSTAL RETINAL 6 works for your dry skin, though other products fit it better because while it hydrates and smooths texture, it lacks specialized ingredients to directly address dryness. A treatment for dry skin needs rich, soothing ingredients that provide significant hydration and skin barrier support, such as ceramides, niacinamide, propolis, peptides, or vitamin C.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/)

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

Retinaldehyde and hyaluronic acid make this serum a fit for your dry skin by hydrating and smoothing texture. To fully address dry skin, a product of this type needs richer moisturizing and barrier-supporting ingredients like ceramides, niacinamide, and peptides.
Sources: [Clinical, Cosmetic and Investigational Dermatology, 2017](https://pubmed.ncbi.nlm.nih.gov/28860834/), [Dermatologic Therapy, 2022](https://pubmed.ncbi.nlm.nih.gov/36200921/)

### What does Retinaldehyde do for dry skin?

Retinaldehyde helps make dry skin feel much smoother while boosting overall skin thickness over time. It is a gentler option that is unlikely to cause heavy irritation when used regularly.
Sources: [Journal of Drugs in Dermatology, 2020](https://pubmed.ncbi.nlm.nih.gov/32574009/), [Dermatology, 1999](https://pubmed.ncbi.nlm.nih.gov/10473959/)

### What does Hyaluronic Acid do for dry skin?

Hyaluronic acid draws moisture into dry skin, giving an immediate and lasting boost in hydration that helps smooth out fine lines and soften rough patches. It is very gentle and unlikely to cause irritation while improving overall skin smoothness and plumpness.
Sources: [Dermatology and Therapy, 2021](https://pubmed.ncbi.nlm.nih.gov/34176098/), [Journal of Drugs in Dermatology, 2011](https://pubmed.ncbi.nlm.nih.gov/22052267/)

### Where does this serum go in a skincare routine for dry skin?

This treatment goes in the evening routine after cleansing and before your moisturizer. Dry skin needs a rich moisturizer and extra nourishing ingredients like plant oils or butters to lock in moisture and fully comfort the skin.

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

You can use this serum with niacinamide by applying niacinamide first in your routine and following with this treatment once it absorbs. This product is unlikely to cause irritation on dry skin, though a product of this type works best for dry skin when it includes rich, nourishing ingredients that deeply lock in moisture.

### How often should I use this serum?

Use this treatment in the evening as part of your nighttime routine. It is safe for your skin with no expected irritation.
Sources: [Facial Plastic Surgery, 2014](https://pubmed.ncbi.nlm.nih.gov/24488631/)

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

This treatment is unlikely to clog pores or cause breakouts on dry skin, though mild dryness or purging may occur as your skin adjusts to the vitamin A. The formula has a safe profile with no harsh ingredients.

### Is this serum fragrance-free and alcohol-free?

Yes, it has no fragrance and no drying alcohol. Cetearyl alcohol is a fatty alcohol, which soften the skin.
