🌿 DIY Lactic Acid Skincare at Home

Naturally Brighten, Smooth, and Hydrate Your Skin

Lactic acid is a gentle alpha hydroxy acid (AHA) that you can find naturally in fermented dairy. But did you know you can recreate its benefits using basic kitchen ingredients? Here's a homemade treatment that works for dry, dull, or uneven skin—without the chemicals.

🥣 DIY Gentle Lactic Acid Glow Mask

🌼 Ingredients:

2 tablespoons full-fat plain yogurt (unsweetened)

1 teaspoon manuka or raw honey

½ teaspoon fresh aloe vera gel

(Optional: A few drops of rosewater for calming effect)

💡 Why These Ingredients Work:

Yogurt is a fermented ingredient rich in skin-friendly acids that help loosen dull, dead cells on the surface—offering a smoother feel without harsh scrubbing

Honey supports hydration and is known for its antimicrobial properties.

Aloe vera calms inflammation and enhances post-mask glow.

🧖 How to Apply:

In a small clean bowl, mix all ingredients until creamy and smooth.

Cleanse your face with lukewarm water (no cleanser needed if your skin is already clean).

Apply a thin layer of the mask, avoiding eyes and lips.

Leave on for 8–12 minutes (less for sensitive skin).

Gently rinse off with cool water using circular motions.

Follow up with a hydrating toner and moisturizer.

✅ Pro Tips:

Apply this mask no more than two times a week to allow your skin time to renew naturally.

Prepare a fresh batch for every use, as homemade blends don't contain preservatives and may spoil quickly.

For dry skin: layer on a few drops of squalane or facial oil after rinsing.

Best used in the evening to allow skin recovery overnight.

⚠️ Caution & Don’ts:

Don’t apply to broken or freshly exfoliated skin.

Avoid sun exposure right after use (wear SPF the next morning).

Skip lemon juice—it's too acidic and can irritate your skin in DIY blends.
