fashionadminmegan Unlock 30 Percent Off: My Favorite Kate Somerville And Biossance Finds Today
I have been skimming through Sephora’s app-only offers since early morning, and I found something that every skincare lover should know before the day ends. Today is November 23, which means only one day stands between us and the Cyber Week madness that starts on the 24th. Before the big storm hits, Sephora is giving a solid 30 percent off on two powerhouse brands loved for real results: Biossance and Kate Somerville. I wanted to make sure no beauty enthusiast, especially my girls with winter-sensitive skin, gets left behind while trying to keep their holiday glow steady.
The weather across the U.S has already started cooling down, heaters are running, and skin is losing moisture faster than usual. That is exactly why these seven products feel like they were designed for this exact week. They brighten, exfoliate, hydrate, resurface, and keep the skin balanced when the air turns sharp and dry. And the best part? The thirty percent discount drops in automatically once you add them to your Sephora cart only if you are signed in on the app.
Before we jump in, here is a quick reminder: Sephora also gives free standard shipping, no minimum. So if you are trying to upgrade your routine while keeping your wallet taking thirty percent less impact, this is the perfect moment.
1. Biossance Squalane + 10% Lactic Acid Resurfacing Serum
Original Price: $65.00
30 Percent Off Price: $45.50
This is one of the most effective nighttime renewal serums for cold weather because it softens dull, tired, winter-worn skin in a single night. Lactic acid is one of the gentlest exfoliating acids, which makes it perfect for dry, normal, oily, or combination users dealing with texture, clogged pores, and dull patches. During late-November cold fronts, cell turnover naturally slows down, which is why resurfacing becomes even more important.
The formula includes vegan lactic acid that gently smooths away roughness and brings visible glow by morning. Clover extract helps the skin bounce back from environmental stress like blue light and pollution, something all of us experience daily. Then there is sugarcane-derived squalane, which adds hydration that lasts the entire night. Nothing in the formula feels heavy or sticky, and the serum blends in quickly with a lightweight finish.
Clinical results back the hype: hydration jumped by one hundred thirteen percent after one use, and one hundred percent of panelists saw reduced pores, better exfoliation, and fewer fine lines. This is why it works so well during colder months when skin needs both renewal and nourishment.
My favorite part about this serum is how rested my skin looks the next morning even when I do not sleep enough.
How to Use
Apply two to three pumps on clean skin at night. Cover your face, neck, and décolleté. Do not rinse. This is gentle enough for nightly use.
Upgrade your evening routine and grab it for $45.50 when you check out through the Sephora app.
2. Biossance Omega Repair Deep Hydration Moisturizer
Original Price: $60.00
30 Percent Off Price: $42.00
Winter air in the U.S is drying out skin faster than usual right now, and this moisturizer was practically made to save skin from tightness, flakiness, and early fine lines that show up when humidity drops. The formula is rich but never greasy, and the triple-boosted hydration from ceramides, hyaluronic acid, and squalane makes this perfect for barrier repair.
Ceramides and fatty acids reinforce the skin’s moisture barrier, keeping hydration sealed in. Hyaluronic acid plumps the skin and softens fine lines. Squalane adds deep nourishment for those cold, windy days that drain moisture from the cheeks and jawline. It is fragrance free and safe for sensitive skin, which becomes even more reactive during winter.
Clinical studies showed that every single participant had improved hydration in five minutes and improved barrier function in one week. That is exactly what our skin needs before December temperatures drop even further.
The first time I tried this cream, the hydration felt instant and long-lasting in a way winter skin rarely gets.
How to Use
Apply morning and night after your serums. Cover your face and neck evenly and allow it to absorb before layering makeup.

3. Biossance Vitamin C Rose Brightening And Firming Face Oil
Original Price: $74.00
30 Percent Off Price: $51.80
If your winter glow disappears the moment temperatures drop, this face oil brings it right back. The star ingredient, THD Ascorbate, is a stable, oil-soluble vitamin C that brightens the skin without irritation. It sinks in quickly and strengthens the skin’s radiance, making it ideal for dullness caused by cold air and indoor heating.
Sugarcane-derived squalane locks in hydration without heaviness, keeping the skin soft through chilly mornings. Chios crystal oil supports firmness and smoothness, which helps skin look more awake even when the days feel darker earlier.
In consumer studies, ninety-seven percent of users agreed that their firmness and suppleness improved. This product shines especially in winter because oils prevent moisture loss better than lightweight lotions.
The glow this oil gives is the kind that looks natural, not forced or greasy.
How to Use
Use as the last step in your routine. Massage a few drops onto the face and neck morning and night.
Grab this winter radiance booster for $51.80 once you add it to your Sephora app cart.
4. Biossance Marine Algae Eye Cream
Original Price: $56.00
30 Percent Off Price: $39.20
This eye cream works beautifully in cold weather when fine lines appear more defined and under-eye skin becomes thin and dry. The whipped texture melts into the skin instantly and creates a smooth base for concealer, which is a major bonus this time of year.
Paracress extract helps firm and relax the look of fine lines. Pink marine algae reduces wrinkles, and squalane provides deep hydration without weighing the area down. In clinical studies, ninety-seven percent of users saw improvement in firmness and fine lines after a single use, and ninety-four percent noticed brighter, lifted skin in one week.
The hydration level makes this ideal for anyone whose under eyes get flaky or creased during winter makeup.
I always notice my concealer looking ten times smoother whenever I use this eye cream.
How to Use
Use after cleansing and before serums. Apply around the eyes, temples, brow bone, and even eyelids. Use twice daily.

5. Kate Somerville EradiKate Acne Spot Treatment (10% Sulfur)
Original Price: $29.00
30 Percent Off Price: $20.30
Cold weather plus stress plus holiday sweets equals breakouts for many of us. This fast-acting sulfur treatment tackles blemishes within one hour. It reduces redness, unclogs pores, and prevents new breakouts from forming. Since winter skin can be dry, the formula keeps things balanced without stripping.
Sulfur minimizes active breakouts. BHA salicylic acid clears pores, and zinc oxide reduces excess oil. It is especially helpful for hormonal breakouts that arrive with seasonal changes or stress.
In clinical trials, ninety-four percent saw visible improvement in one hour, which is exactly why this is a holiday-season essential.
This is my go-to emergency fix for overnight spot control.
How to Use
Dip a cotton swab into the pink sediment and apply directly to blemishes. Do not shake the bottle. Rinse after one hour or leave overnight.
Handle your winter breakouts for $20.30 by checking out through the Sephora app.
6. Kate Somerville ExfoliKate Daily Foaming Wash
Original Price: $46.00
30 Percent Off Price: $32.20
Winter makes skin dull faster because dead skin builds up more quickly. This foaming cleanser uses fruit enzymes and AHAs to keep your skin bright and clear every day. It removes makeup, SPF, and impurities without drying the face.
Papaya, pineapple, and pumpkin enzymes exfoliate gently. Glycolic and lactic acids refine pores and smooth texture, which is ideal when dry patches start forming during cold winds. Users reported softer, fresher skin from the first wash.
I love how this cleanser keeps my skin glowing even in freezing wind.
How to Use
Use morning and night. Massage a small amount onto wet skin for thirty seconds, then rinse.

Original Price: $55.00
30 Percent Off Price: $38.50
This moisturizer is a winter staple for anyone wanting smoother texture and brighter tone. It uses AHA acids plus hydrating botanicals to keep the skin balanced. It works for all skin types and keeps fine lines soft even in cold air.
