Summer Wrecked Havoc on My Skin and Hair—These 13 Budget-Friendly Sale Items Will Help


UV rays! Saltwater! Chlorine! Summer is always hard on my hair and skin, but this year, it's next-level. I spent lots of time traveling in dry climates. I laid out on the beach under the hot sun. I maintained an inconsistent sleep schedule peppered with cocktail hours and late-night dinners. Sure, I had fun, but I incurred some serious skin and hair damage.
Allow me to give you all the unsavory details. Firstly, my hair is dry and brittle, and I have more split ends than I can count. It's not cute. Secondly, despite diligent sunscreen application, my skin is dull and discolored. It's always been prone to hyperpigmentation, so I'm not surprised TBH. Generally speaking, I need a glow-up—not just in an aesthetic sense but also in a "skin and hair health" sense.
Luckily, Dermstore's Anniversary Sale is on through August 18. Select products are up to 25% off with the code CHEERS. During it, I'm snagging damage-reversing skin and hair products at a discount. Think brightening vitamin C serums, moisturizing hair masks, dark spot–fading exfoliants, and more. Ahead, see every single item I'm buying to reverse late-summer skin and hair damage.
Skincare

Before I do anything else, I want to fade dark spots and discoloration from sun damage. This two-step exfoliating peel uses seven AHAs and BHAs to reduce the look of fine lines, wrinkles, dullness, discoloration, acne scars, pores, and more. It's the perfect post-summer skin brightener.

This LED mask uses seven (yep, seven!) light therapy treatment modes to target basically every single skin concern I can think of. I can't wait to start using this regularly for a fall skin reset. Check out the deets on each light therapy treatment mode:
- Red light: promotes collagen production to smooth lines and wrinkles
- Blue light: reduces breakouts
- Green light: soothes irritated skin
- Yellow light: improves skin texture
- Purple light: repairs acne scars
- White light: boosts skin metabolism to improve tone and sagging
- Clear blue light: enhances cell energy for healthier skin

With my summer sun damage, a good vitamin C serum is a must. This one uses two advanced forms of vitamin C (tetrahexyldecyl ascorbate and 3-O-ethyl ascorbic acid) to brighten the skin, reduce dark spots and discoloration, defend against pollution, and offer anti-aging benefits. I love that it's fragrance-free to avoid further irritating my sensitive skin.

I'm not done with the brightening products yet. This one combines vitamin C with skin-polishing microdermabrasion. I'm going to use it to slough off dead skin, smoothing the rough texture around my nose and mouth and evening my skin tone.

ICYMI, snail mucin is so good for the skin. It's hydrating, anti-inflammatory, and antioxidant rich, so it's no wonder this TikTok-viral product is a best seller. I can't wait for the glass skin this is going to give me.
Deal: 20% off
Retinol is still the gold standard in anti-aging, and with all the sun damage I have, I'm committing to using it three nights a week come fall. Over time, it will resurface my skin to smooth lines and wrinkles and fade dark spots and discoloration. Of course, I'll wear sunscreen every day, as it makes the skin more sensitive to UV rays.
Deal: 20% off
I took a break from face oils during the summer when my skin veered on the oily side. For soft, plump skin as the weather turns cooler, I'm bringing them back—Pai's Rosehip Bioregenerate Universal Facial Oil in particular. The multitasking formula is rich in cold-pressed rosehip and seed oils, omegas, and antioxidants. It improves everything from dryness and dullness to firmness, blemishes, and acne scars. Plus, it gives my skin the most incredible glow.
Haircare
Deal: 20% off
Here's something you rarely think about—the water you shower in at home. Often, your household water supply contains high levels of minerals like chlorine that lead to dullness, dryness, and frizz. (FYI: That's what the term "hard water" refers to.) This handheld showerhead contains a filter that uses a complex blend of tourmaline, calcium, zinc, and copper to remove damaging minerals from the water before they hit your hair and skin. That means you'll see shinier, sleek, and healthier hair and more hydrated skin without using a single product.
Deal: 25% off
I can't tell you just how much I love this hair oil. It's one of the only formulas that *actually* does what it says it will—hydrating, smoothing, and strengthening damaged hair. My bleached strands basically drink it up, which is why I'm snagging two or three bottles while it's on sale.
Deal: 25% off
A classic. A masterpiece. An icon. This moisturizing hair mask uses algae extract, B vitamins, almond oil, and rosehip oil to nourish, strengthen, and repair damaged strands. I've had one of these little white tubs in my shower for years, and I'm snagging another one during this Dermstore sale.
