Skincare FAQs

Is vitamin C serum a good fit for menopause skin?

Yes. During the menopause transition, skin often starts to look duller, drier, and less even, partly because the hormonal shifts that once supported natural luminosity are changing. A vitamin C serum formulated for this — with the full antioxidant trio of L-ascorbic acid, ferulic acid, and tocopherol, plus hydration support from sodium hyaluronate and squalane — gives skin more than a generic serum does. Radiance C + Ferulic Serum is designed for the visible changes that appear during perimenopause and beyond.

What does ferulic acid actually do in a vitamin C serum?

Ferulic acid does something single-ingredient serums can't: It stabilizes L-ascorbic acid, which is notoriously sensitive to air and light, and it supports antioxidant performance across the full trio. The vitamin C, E, and ferulic acid combination is among the most studied in topical antioxidant research. In this serum, it ensures your vitamin C is working at its best, not degrading in the bottle or on your skin.

Does this vitamin C serum help with the look of dark spots?

Yes, when used consistently. L-ascorbic acid helps support a more even-looking tone, and with regular use, the appearance of dark spots and uneven pigmentation can soften over time. Pair it with daily broad-spectrum sunscreen to protect those results long term.

Should I use vitamin C serum in the morning or at night?

It’s best used in the morning. L-ascorbic acid provides antioxidant support that works alongside your daily exposure to environmental stressors. Apply after cleansing, before moisturizer, and follow with SPF.

Is this serum comfortable on dry menopause skin?

Yes. The formula pairs its antioxidant layer with sodium hyaluronate, glycerin, squalane, and panthenol — ingredients that support hydration and help skin feel softer, feel more comfortable, and look more moisturized. This serum is designed to target the dryness that often comes with the menopause transition in addition to delivering antioxidants.

Who should introduce this serum slowly?

Anyone with extremely sensitive skin, a compromised skin barrier, rosacea-prone skin, or active acne should check with a dermatologist before use, because L-ascorbic acid can be irritating on skin that is already reactive. If you're already using strong exfoliants or retinoids, introduce this serum gradually, every other day at first, and give skin time to adjust before layering active ingredients. If you experience persistent redness or irritation, pause and check with a doctor.

What combination of skincare products do I need?

Our Core → Defense → Renewal system makes it simple. Cleanse and moisturize daily (Core). Protect with antioxidants and SPF (Defense). Add targeted treatments for the specific signs you most want to address (Renewal).

What makes Winona's skincare different from other products?

Winona's skincare is physician-curated and designed specifically for women in the menopause transition and beyond. Our line uses clinically-proven ingredients chosen for the visible changes that appear at this stage of life. While it was created with menopausal women in mind, the line serves as premier skincare for any woman over 30.

Can I use Winona's skincare with HRT, and do I need to be on HRT for it to work?

Winona’s skincare is an excellent complement to HRT but does not require HRT to work. Both can be used independently or in combination, as they serve different purposes. HRT addresses the root hormonal shifts, principally estrogen decline, that lead to a range of symptoms, including skin changes. While HRT can improve skin health, it is not a skin-specific treatment and cannot reverse existing changes like lost firmness, uneven tone, or dryness. Winona’s skincare is formulated specifically around these concerns to address skin barrier health, loss of hydration, accumulated sun damage, skin laxity, and collagen loss.
